Abstract: - From the perspective of enterprise innovation, this paper studies whether companies with higher
ownership concentration are willing to hire a technology CEO. This paper studies the relationship between
ownership concentration, CEO’s technical background, and enterprise innovation by taking private listed
companies on small and medium-sized boards in Shenzhen Stock Market from 2011 to 2019 as research
samples. The results show that CEO’s technical background promotes enterprise innovation. However,
enterprises with higher ownership concentration are more willing to hire a non-technology CEO. Ownership
concentration not only directly hinders enterprise innovation, but also indirectly hinders enterprise innovation
by hindering the selection and recruitment of technical CEOs. Further research shows that under the condition
of shareholding, technology CEOs significantly promote enterprise innovation, while under the condition of
non-shareholding, technology CEOs have no significant impact on enterprise innovation. Without serving as
chairmen, technical CEOs significantly promotes enterprise innovation, while serving as chairmen, technical
CEOs have no significant impact on enterprise innovation. However, in the samples with high ownership
concentration, there are significantly more companies where CEO serves as chairman and significantly fewer
companies where CEO holds shares, which indicates that companies with high ownership concentration do not
actively implement innovation incentive measures for CEOs. This study provides an important basis for
Chinese private small and medium-sized enterprises to make innovative decisions in major shareholder
governance and general manager selection.

1 Introduction
Enterprise innovation is an important means to
enhance the core competitiveness of small and
medium-sized enterprises and a powerful driving
force to promote the high-quality development of
the national economy. As two key figures of
enterprise innovation, the influence of major
shareholders and general managers on enterprise
innovation cannot be ignored. In recent years,
foreign technology companies have successively
appointed technical talents to CEO positions. For
example, in 2014, Microsoft appointed Satya
Nadella with technical background as its new CEO.
In 2015, Google named product chief Sundar Pichai
as its new CEO; In April 2020, IBM named
engineer Arvind Koshner as its new CEO; In
February 2021, Intel named technology veteran Pat
Gelsinger as its new CEO. However, from 2011 to
2019, the number of CEOs with technical
backgrounds in domestic private small and medium-
sized listed companies declined year by year. Under
the background of the urgent improvement of
technical innovation ability, why the small and
medium-sized private listed companies in China are
more and more reluctant to hire technical CEOs
with technical backgrounds? Are technology CEOs
hindering enterprise innovation? if not, then why are
enterprises unwilling to hire a technology CEO? Is it
because of a dominant share structure? The
motivation behind this paper is to find out the
reason behind this phenomenon.
The contribution of this paper is to study major
shareholders, technology CEOs, and corporate
innovation together. Most of the existing literature
only studies the influence of shareholders on
enterprise innovation, or the influence of managers
on enterprise innovation, and there is a lack of
integration of managers, shareholders, and
enterprise innovation. First, this paper chooses the
CEO group of small and medium-sized enterprises
to study the relationship between technology CEOs
and enterprise innovation. As for the relationship
between technology CEOs and enterprise

innovation, most literatures think that the
relationship is positive, [1], [2]. While a few
literatures think that the relationship is not
significant, [3]. The research conclusions are not
uniform, and the research objects are concentrated
in high-tech industries. The kinds of literature focus
on the technical backgrounds of executive teams,
rather than specific types of executives, such as
CEOs. Second, this paper studies the relationship
between ownership concentration and enterprise
innovation. As for the relationship between
ownership concentration and enterprise innovation,
the conclusions include a positive correlation, [4], a
negative correlation, [5], and an inverted U-shape
correlation, [6]. The research conclusions are not
uniform yet. Thirdly, this paper studies the
relationship between the shareholding ratio of the
largest shareholder and the selection and
employment of technology CEOs, as well as the
mediating effect of technology CEOs between
ownership concentration and enterprise innovation,
which has not been studied in the previous
literature.
However, Chinese enterprises generally face two
kinds of agency problems, that is, the agency
problem between major shareholders and minor
shareholders, and the agency problem between
shareholders and managers. Under the background
of imperfect company law, large shareholders will
interfere in the selection of general managers and
appoint acquaintances and relatives as senior
executives. Therefore, it is crucial to integrate major
shareholders, general managers, and enterprise
innovation into a research framework to improve the
level of enterprise innovation. Therefore, this paper
takes the private non-financial listed companies in
the SME board from 2011 to 2019 as the research
object and studies the relationship between the
three. This study helps to explain the objective
phenomenon that the average technical background
of CEOs of private listed companies on small and
medium-sized boards has declined year by year in
the past 10 years. This study is also helpful to
explain the micro-mechanism of ownership
concentration affecting enterprise innovation and
enrich the theoretical research of enterprise
innovation.
2 Theoretical Analysis and Research
Hypothesis
2.1 CEO with a Technical Background and
Enterprise Innovation
The high-level echelon theory, first proposed by
Hambrick & Mason in 1984, holds that managers
are bounded rationality, unable to fully understand
the development of things, and can only make
decisions based on their own experience and
cognition, [7]. As the most important manager of an
enterprise, the technological experience and
cognition of CEOs will have a positive impact on
enterprise innovation, which is reflected in the
strong driving force of technological CEOs to carry
out enterprise innovation activities and reduce the
risk of enterprise innovation.
First, technical CEOs have a higher drive for
technological innovation. Internal motivation is the
source of power to ensure the vitality of enterprise
innovation. The innovation drive of technical CEOs
comes from their high cognition of innovation
activities, their ability to overcome the short-
sightedness of management, and their self-worth
realization needs. First, technical CEOs have a high
awareness of enterprise innovation, because
executives tend to internalize work experience into
cognitive ability, thus affecting the formulation and
implementation of corporate decisions, [8]. The
technical work experience of CEOs enables them to
have a relatively comprehensive understanding of
the process of enterprise R&D, deeply realize the
importance of financial support for enterprise R&D,
and are more willing to invest in product or
technological innovation, [9]. Second, technical
CEOs can overcome the short-sightedness of
management, because short-sighted management is
common in listed companies due to internal and
external pressures, which prevents management
from engaging in high-risk innovative activities,
[10]. Technical CEOs often have invention
experience and relatively high technological
innovation ability. To a certain extent, the inventor
background of senior executives can curb the short-
sightedness of corporate management, which is
conducive to increasing the long-term technological
innovation investment of enterprises, [11]. On the
other hand, high-ability managers pay more
attention to reputation and can get higher salaries, so
they have weaker motivation to maximize their
interests through rent-seeking behavior, [12], [13],
[14]. Third, technology CEOs need self-realization.
According to Maslow’s five-level demand theory,
CEOs in top management positions need to

Volume 11, 2023
maximize their skills. So they are more likely to
focus on technological innovation and transform
their technological talents into new products through
innovative activities.
Second, technological CEOs can reduce the risk
of innovation. The specific reasons are as follows.
First, the innovation opportunities found by
technical CEOs are more valuable. As technical
experts in this field, technical executives have deep
professional knowledge, a deeper understanding and
grasp of the technological frontier, and a strong
sensitivity to the development direction of the
industry and the technological innovation frontier,
so they can provide efficient guidance and
suggestions for enterprise innovation, and can
explore more valuable innovation opportunities,
[15]. Second, enterprises with technical CEOs can
provide positive signals to the market and provide
financial guarantees for innovative activities.
Studies have found that academic CEOs can inhibit
enterprise R&D manipulation and thus improve
enterprise innovation efficiency, [16]. Therefore,
appointing a technology CEO can send a signal to
the market that the company is serious about
technology, increase investor confidence, and thus
obtain more financial support. Third, technical
CEOs can integrate innovation resources more
effectively. Executive social networks promote
enterprise innovation through obtaining information
advantage, obtaining a capital advantage, and
reducing risk levels, [17]. There are many resources
within the social network, and the technical
relationship network formed by technical CEOs can
establish the “intangible innovation research
network”, bring technical social resources to the
enterprise, which is conducive to the enterprise
obtaining innovation information, timely adjusting
innovation deviation, and solve innovation
problems.
So this paper proposes hypothesis 1: CEOs with
technical backgrounds promote enterprise
innovation.
2.2 Ownership Concentration and
Enterprise Innovation
Shareholders are often divided into major
shareholders and minority shareholders due to their
different shareholding ratios. The shareholding ratio
is a symbol of shareholders’ decision-making power
and cash flow right. The higher the shareholding
ratio is, the higher the concentration of decision-
making power and cash flow right. Major
shareholders have higher shareholding, greater
decision-making power, and cash flow power, so
they have a greater probability of abuse of power. In
the context of one share, one right” in China, small
and medium-sized innovative private enterprises
adopt an equity-dominated governance structure,
and the shares are mostly held by the founders, [18].
A dominant share is not conducive to access to
innovation funds, and is not conducive to the
independence of innovation decisions, for the
companies. Therefore, ownership concentration may
negatively affect enterprise innovation.
First of all, a dominant share is not conducive to
access to innovation funds. The specific reasons are
as follows. First, major shareholders have
“hollowing out” behavior. Johnson et al. first put
forward the idea that major shareholders “hollow
out” the company. In the case of equity
concentration, to obtain private interests, large
shareholders will occupy the resources of listed
companies using tunnels, [19]. There are various
ways for major shareholders to hollow out listed
companies, including related transactions, fund
occupation, and cash dividend policy, [20]. A large
number of studies have found that the higher the
degree of ownership concentration is, the stronger
the motivation and ability of major shareholders to
hollow out listed companies [21], [22]. The
hollowing behavior of major shareholders
encroached on the limited resources of the company
and restricted the cash flow to enterprise innovation.
Second, the high uncertainty of innovation makes
major shareholders have no investment intention.
The high uncertainty of innovation activities is
reflected in high investment, high risk, long cycle,
and easy to imitate. New products from research and
development to marketization, not only need
enterprises to invest a lot of human resources and
material resources, but also face the risk of failure
and free rider effect at any time. In an environment
where intellectual property protection is weak, the
innovation achievements of enterprises are more
likely to be modeled. Due to the high shareholding
ratio, if the innovation investment fails, the major
shareholders will face greater losses. Therefore,
major shareholders prefer stable management and
are not willing to invest in innovation.
Secondly, a dominant share is not conducive to
the independence of innovation investment
decisions. The specific reasons are as follows. First,
the independence of innovation decision-making of
the board of directors decreases. At present, the
main form of the governance structure of listed
companies is “one layer three meetings”, which
include shareholders’ meetings, boards of directors,
supervisory boards, and senior management, the
WSEAS TRANSACTIONS on COMPUTER RESEARCH

Volume 11, 2023
core of which is the board of directors. The
members of the board of directors who are elected
by the general meeting of shareholders decide on the
company’s business plan and investment plan. The
general meeting of shareholders is composed of all
shareholders and is the highest authority of the
company, exercising decision-making and
supervision power on behalf of all shareholders.
Due to the high proportion of shareholding, major
shareholders have larger voting power in the general
meeting of shareholders, and even one vote
determines the result. The members of the board of
directors elected by the general meeting of
shareholders reflect the will of major shareholders,
and the board of directors is likely to become the
dominant voice of major shareholders and cannot
play its core role in corporate governance, [23].
Which greatly reduces the independence of
innovation decision-making of the board of directors
decreases. Second, major shareholders hold the
power to make decisions on important matters. The
separation of ownership rights and control rights
gives birth to the corporate governance mechanism,
but because of the scarcity of capital, and the
matching of responsibility and right, the
phenomenon of excessive centralization of major
shareholders in our country has always existed,
resulting in the fact that the ownership rights and
control rights of companies are not separated in
essence. A single major shareholder holds the
largest ownership of the company, the right to
nominate and appoint executives, and the right to
make investment decisions. Small shareholders have
difficulty challenging large shareholders because of
their low shareholding ratio. The majority
shareholder essentially controls the company.
Although listed companies have established
corporate governance mechanisms in accordance
with regulatory requirements, whether this
mechanism can operate smoothly depends entirely
on the will of major shareholders. The over-
centralized major shareholders, limited by their
vision and risk aversion preference, would rather the
company develop slowly than delegate power,
resulting in the company falling into the “major
shareholder trap” and difficult to carry out
innovative activities. The research found that a high
degree of ownership concentration means a high
degree of risk concentration, [24], leading to major
shareholders using their control rights to intervene
in high-risk investment decisions and refusing to
invest in R&D innovation projects with large
amounts, long-cycle, and uncertain returns, [25].
Under the condition of high ownership
concentration, the opinions of various stakeholders
are often represented by major shareholders, and it
is difficult to express their interest demands, which
makes it difficult to realize the scientific nature and
independence of innovation investment decisions.
So this paper puts forward hypothesis 2:
ownership concentration inhibits enterprise
innovation.
2.3 Ownership Concentration and Technical
CEOs
Currently, the manager market in China is not
perfect, and the executive turnover rate is low, [26],
which indirectly reflects that companies prefer to
select senior executives from within rather than
directly recruit from outside. Compared with
enterprises that parachute management talents from
the outside, enterprises that train management
talents internally can establish a more effective
innovation incentive mechanism, better motivate
executives to improve the efficiency of asset use,
and promote the improvement of enterprise
innovation ability, [27]. But whether trained
internally or parachuted from the outside, the
common characteristic of technical CEOs is a past
or present technical background. Based on theories
such as the self-interest protection of major
shareholders, the influence of Chinese relationship
culture, and the transmission of negative signals, it
is speculated that enterprises under the control of
major shareholders are less likely to hire executives
with technical backgrounds.
First, large shareholders have a stronger
incentive to resist technical managers. The
separation of ownership and management makes the
agency problem of shareholders and managers
always exist, that is, the first kind of agency
problem. According to the hypothesis of economic
man, shareholders, and managers have inconsistent
interests. Managers may take advantage of
information advantages and management rights to
maximize their interests rather than the interests of
shareholders. Appointing technical personnel as
technical executives may increase the degree of
information asymmetry between shareholders and
managers and make the agency conflict between
them more serious. Compared with non-technical
CEOs, technical CEOs have a deeper understanding
of the implementation of innovation investment
plans and have more opportunities to maximize their
interests. To reduce supervision costs, shareholders,
especially major shareholders, may intervene in the
decision of the board of directors to select CEOs
and reduce the selection of technical CEOs.

Secondly, the influence of relationship culture in
China. The influence of culture on corporate
governance is just as important as the system, but
more deep-rooted and hidden. In the case of a low
level of social trust, influenced by the traditional
culture of “cronyism” in China, the board of
directors is more inclined to choose relatively
familiar personnel when hiring general managers.
The “one-share dominance” of corporate ownership
structure in China is one of the root causes of the
formation of the nepotism board culture, [28].
Companies with strong boards of directors often
choose candidates with similar characteristics to the
board of directors as the new CEOs, [29]. The
research finds that only private enterprises with high
operational risks are more willing to recruit senior
executives from outside to supplement management
talent due to their greater demand for management
talent, [30]. That means hiring a CEO from outside
sends a signal that the company is riskier. Most
private listed companies prefer to select CEOs from
within the company. Technical internal members
have relatively weak interpersonal skills, and it is
difficult to form a familiar relationship with the
board members who decide the appointment and
removal of the general manager. As a result, boards
are much less likely to hire a technical CEO.
So this paper proposes hypothesis 3: Companies
with a higher concentration of ownership are more
likely to hire non-technical CEOs.
2.4 The Mediating Effect of Technical CEOs
in the Relationship between Ownership
Concentration and Enterprise Innovation
The two major agency problems in corporate
governance are agency conflict between
shareholders and managers, and agency conflict
between major shareholders and minority
shareholders. The common core of these two
problems is the major shareholder. On the one hand,
major shareholders should prevent the inaction and
benefit theft of outsiders (managers), and on the
other hand, they should exercise important decision-
making power on behalf of insiders (minority
shareholders). The articles of association of the
company stipulate that the general meeting of
shareholders shall decide on the overall plan of
innovation investment, the board of directors shall
decide on the action plan of innovation investment
and the appointment of the management, and the
management shall organize the implementation of
the innovation investment plan. Previous studies
have found that the company’s attributes have a
greater impact on enterprise innovation than the
managers’ attributes, which may be because the
company’s attributes directly affect enterprise
innovation and indirectly affect enterprise
innovation through managers. The attributes of
enterprises are often the embodiment of the
willpower of major shareholders. Therefore, this
paper speculates that the influence of major
shareholders on enterprise innovation is not entirely
direct.
So this paper puts forward hypothesis 4: The
controlling majority shareholders may indirectly
affect enterprise innovation by influencing the
selection and recruitment of technical CEOs.
3 Empirical Research Design
3.1 Sample Selection and Data Sources
The initial research samples of this paper are all the
private listed companies on the small and medium-
sized boards in Shenzhen Stock Market from 2011
to 2019, which are excluded according to the
following criteria: (1) Listed companies in the
financial industry; (2) ST and *ST companies
during the sample period; (3) The absence of
management information and corporate financial
data; (4) Companies with an asset-liability ratio
greater than 1; (5) The IPO companies of that year.
After screening, the final study sample size was
3476 company observations. The sample period
begins in 2011 to eliminate the impact of the 2008
financial crisis on corporate innovation and ends in
2019 to eliminate the impact of the COVID-19
pandemic on corporate innovation. The technical
background data of the CEO in this paper are
obtained after manual sorting according to the
executive resumes in the CSMAR database, and
other financial data are from the CSMAR database.
To eliminate the influence of extreme values, a
boxplot was used to detect whether outliers existed
in all continuous variables, and a 1% tail reduction
was carried out. The data analysis software used in
this paper is Stata13.1.
3.2 Design of Main Variables
(1) Ownership concentration (Top1)
Referring to Chen and Chen’s research, the
shareholding concentration variable is measured by
the proportion of the largest shareholder, [31]. This
index can reflect the decision-making ability and
control degree of major shareholders in the
enterprise and is a symbol of the power of discourse.

(2) CEO’s technical background (Tech)
Referring to Zhang’s research, if the CEO has
the career background, professional background,
and academic background related to the main
business of the currently employed listed company,
the CEO is considered to have the technical
background, and the value is 1; otherwise, the value
is 0, [32].
(3) Control variables
Referring to Yu and Li’s research, the control
variables include enterprise Size (Size), operating
performance (ROA), growth opportunity (TQ), net
operating cash flow (OCF), listing years (Age), and
debt level (Lev), [33]. In addition, this paper
controls for annual and industry effects. See Table 1
for specific variable definitions. All control
variables are indicated in the following model and

3.3 Model Construction
In order to test hypothesis 1, referring to Chen and
Lian’s research, this paper builds model (1), [34].
The specific model is as follows. Fixed effects
control the annual and industry effects of the
enterprise.
(1)
In order to test hypotheses 2, 3, and 4, referring
to Fang, Wen, and Zhang’s research, this paper
builds model (2) - (4), [35]. The establishment of
the mediating effect of CEOs’ technical background
needs to meet the following three conditions: (1) the
regression coefficient of the equity concentration
variable (Top1) on enterprise innovation variable
(RD) reaches a significant level; (2) The regression
coefficient of the equity concentration variable
(Top1) on the intermediary variable CEO technical
background (Tech) reached a significant level; (3)
When equity concentration (Top1) and CEO
technical background (Tech) are included in the
regression at the same time, the coefficient of
CEOs’ technical background (Tech), the
intermediate variable, reached a significant level. If
the coefficient of ownership concentration (Top1) is
not significant, CEOs’ technology background
(Tech) plays a complete mediating effect. When the
coefficient of ownership concentration (Top1) is
still significant, CEOs’ technology background
(Tech) plays a part in the mediating effect. The
following models are constructed respectively in
this paper:

4.1 Analysis of Descriptive Statistical
Results
From Table 2, it can be seen that the average,
maximum, and minimum levels of innovation
input(RD) are 0.045, 0.211, and 0.000, indicating
that there are great differences in the innovation

investment levels of small and medium-sized private
enterprises in China. Among the 3476 observed
values, 1151 of them had an innovation investment
level above 0.045, accounting for 33.11%, which
indicates that the innovation investment level of
small and medium-sized private enterprises in China
is generally low. There is a big difference between
the maximum value of 0.698 and the minimum
value of 0.041 of ownership concentration (Top1),
which indicates that the shareholding ratio of the
largest shareholder of small and medium-sized
private enterprises is quite different. The average
value of CEOs’ technical background (Tech) is
0.421, which shows that the proportion of
technology CEOs is low.
However, in the group with higher ownership
concentration, the number of companies with
technology CEOs is significantly less, which proves
that companies with higher ownership concentration
are not inclined to hire a technical CEO. In the
group with higher ownership concentration, the
number of companies with a CEO as the chairman is
more, which preliminarily indicates that companies
with higher ownership concentration are not willing
to hire external CEOs, and are more inclined to
concentrate decision-making power in the hands of
shareholders’ representative --chairman. In the
group with a higher concentration of ownership, the
number of companies in which the CEO holds
equity is significantly less, which may indicate that
a dominant company rarely uses equity incentive
measures to motivate the CEO, because the major
shareholders do not want the CEO to become a
shareholder, to facilitate the major shareholders to
infringe on the interests of minority shareholders.

4.2 Analysis of Regression Results
This paper mainly adopts the fixed-effect regression
model of panel data for empirical tests, and the
specific regression results are shown in Table 3.
According to Column 1 of Table 3, the regression
coefficient of CEO technology background (Tech) is
significantly positive at the 1% level, which
indicates that CEO technology background
promotes enterprise innovation, and hypothesis 1 is
confirmed. According to Column 2 of Table 3, the
regression coefficient of ownership concentration
(Top1) is significantly negative at the 1% level,
which indicates that ownership concentration
inhibits enterprise innovation, and hypothesis 2 is
confirmed. According to the third column of Table
3, the regression coefficient of ownership
concentration (Top1) is significantly negative at the
1% level, which indicates that the higher the
ownership concentration is, the less likely the
enterprise is to hire technology CEOs. Hypothesis 3
is confirmed. According to the fourth column in
Table 3, the regression coefficient of equity
concentration (Top1) is significantly negative at the
1% level, and the regression coefficient of CEOs’
technology background (Tech) is significantly
positive at the 1% level, which indicates that CEOs’
technology background (Tech) plays a partial
mediating effect in the negative relationship
between equity concentration (Top1) and enterprise
innovation input (RD). Hypothesis 4 is confirmed.

Enterprise Size (Size), growth opportunity (TQ),
and listing years (Age) are positively correlated with
enterprise innovation. Because companies with
larger scales, higher growth, and longer-lasting life
have more economic strength and ability to invest in
innovation. However, operating performance
(ROA), net operating cash flow (OCF), and debt
level (Lev) are negatively correlated with enterprise
innovation. Because the source of enterprise
innovation funds is not mainly dependent on their
funds and external liabilities.

Note: *, **, and *** are significant at the level of 10%,
5%, and 1%, respectively. The square brackets below the
regression coefficient are the T value or Z value, the
same as below. In the fixed effects regression method, R2
refers to within R-squared; in the probit regression
method, R2 refers to Pseudo R2; in the mixed OLS
regression method, R2 refers to R-squared. In the process
of regression, Breusch & Pagan LM test and Hausman
test were carried out in this paper, and a fixed effect
model was adopted.
4.3 Endogeneity Test
There may be a problem of sample self-selection
between the technical background of CEOs and
enterprise innovation, that is, enterprises with a high
level of innovation investment may be inclined to
hire technical CEOs. To solve the possible problem
of sample self-selection, Heckman's two-stage
method is adopted in this paper. In the first stage,
the Logit model was used to estimate the probability
of hiring technical CEOs, and the inverse Mills ratio
(IMR) was calculated according to the estimated
results. In the second stage, IMR was substituted
into the original regression model as a control
variable. Referring to Li and Liu’s research, the
instrumental variable adopts the proportion of
technology-based CEOs of other enterprises in the
same industry in the same year, [36]. The specific
regression results are shown in Table 4. The
regression results of the first stage (column 1 of
Table 4) show that the regression coefficient of the
instrumental variable IV_Tech is significantly
negative at the 1% level, which indicates that the
instrumental variable IV_Tech is highly correlated
with the endogenous variable, and the instrumental
variable is effective. The results of the second stage
regression (column 2 of Table 4) show that the
regression coefficient of IMR is not significant, and
the technical background (Tech) of CEOs is
significantly positive at the 1% level, which
indicates that the result of hypothesis 1 is relatively
robust.

4.4 Robustness Test
First, this paper remeasures the ownership
concentration variable. To eliminate measurement
bias, the Herfindale index (H1) is used to measure
equity concentration, [37]. The specific regression
results are shown in Table 5.

Volume 11, 2023
Second, this paper remeasures the technical
background variables of CEOs. Considering that
technological innovation requires the management
to find innovation opportunities, integrate
innovation resources, make innovation plans, and a
series of complex activities that need a certain
amount of time to complete. In other words,
technological CEOs have a time lag effect on
enterprise innovation. So the CEOs’ technology
background variable (Tech) is advanced one phase.
The specific regression results are shown in Table 6.
Third, this paper remeasures the enterprise
innovation variables. (1) To eliminate the industrial
differences in enterprise innovation, the intensity of
R&D investment adjusted by the annual and
industrial mean is used to measure the enterprise
innovation level. The specific regression results are
shown in Table 7. (2) This paper remeasures the
level of enterprise innovation from the aspect of
innovation output. Based on the study of Chen et al.,
ln (total patent applications +1) is used to measure
enterprise innovation, [38]. The specific regression
results are shown in Table 8. The results in Table 5,
Table 6, Table 7, and Table 8 show that the results
in this paper are robust.

5 Further Analysis
The regression results above show that the technical
background of the CEO promotes firm innovation.

This part further studies how to better play the role
of CEOs’ technology background in promoting
enterprise innovation. This paper mainly considers
the factors such as the shareholding of the CEO and
the combination of the managing director and
chairman.
5.1 Whether the CEOs Hold Shares or Not
There is a common overlap between shareholders
and managers in family enterprises. The data in this
paper shows that the shareholding ratio of CEOs is
73.96%. Management shareholding can effectively
alleviate the first kind of agency problem so that the
interests of management and shareholders converge.
CEOs holding shares have the dual identities of
shareholders and managers, so they will reduce
short-sighted behaviors, give play to the sense of
ownership and increase innovation input. The
samples are grouped according to whether the CEO
holds shares. When the CEOs hold shares of the in-
service company, the variable value is 1; otherwise,
it is 0. According to the grouping regression results
in Table 9, under the condition of shareholding, the
technical background of CEOs is significantly
positively correlated with innovation input, while
under the condition of non-shareholding, the
technical background of CEOs is not significantly
positively correlated with innovation input. This
indicates that equity incentives play a positive role
in motivating technical CEOs to increase R&D
intensity.
5.2 Whether the CEO also Serves as the
Chairman
Most small and medium-sized private enterprises
are family enterprises, and it is common to combine
the chairman and general manager. The data in this
paper shows that 37.50% of the sample of small and
medium-sized private enterprises combine the
chairman and general manager. On the one hand, the
two-in-one leadership structure of the board of
directors weakens the supervisory function and
decision-making independence of the board of
directors, which provides convenient conditions for
the general manager to pursue his interests. On the
other hand, it distracts the technical CEOs’ energy
to concentrate on technology. As a result, the
appointment of a technology CEO as chairman may
reduce investment in innovation.
If the position of chairman and general manager
shall be assumed by one person, the value is 1;
otherwise, the value is 0. According to the grouping
regression results in Table 9, the technical
background of CEOs is significantly positively
correlated with enterprise innovation input under the
condition of non-integration of two jobs, while the
technical background of CEOs is not significantly
positively correlated with enterprise innovation
input under the condition of integration of two jobs.
This indicates that the non-dual board governance
structure is conducive to the increase of innovation
investment for technology CEOs.

6 Research Conclusions and Policy
Recommendations
6.1 Research Conclusions
It is worth thinking about how to develop the
positive factors, overcome the negative factors, and
obtain the excess profit of innovation for small and
medium-sized enterprises. This paper takes the
panel data of non-financial small and medium-sized
private listed companies in the Shenzhen Stock
Market from 2011 to 2019 as samples. Starting from
two key figures, major shareholders and technical
CEOs, through theoretical reasoning and empirical
analysis, this paper finds out their roles in enterprise
innovation. It is found that the controlling
shareholder not only directly inhibits enterprise
innovation, but also indirectly inhibits enterprise
innovation by influencing the selection of
technology CEOs. Further research shows that
technical CEOs can significantly promote enterprise
innovation under the condition that CEO holds
shares or does not concurrently serve as chairman.
These conclusions are consistent with the history
and culture of China, the development of the capital
market, and the characteristics of small and
medium-sized enterprises. First of all, Chinese
enterprises are influenced by traditional culture, and
the idea of moderation occupies the mainstream.
They do not like to take risks and do not like to be
the first to try. As a relatively vulnerable group, the
WSEAS TRANSACTIONS on COMPUTER RESEARCH
DOI: 10.37394/232018.2023.11.21
Yuping Shi
E-ISSN: 2415-1521
239
Volume 11, 2023
owners of small and medium-sized enterprises are
more reluctant to participate in risky activities, such
as innovation. Second, in China, the capital market
started late and is not perfect. The major
shareholders use the advantage of equity to interfere
excessively in the decision-making of the board of
directors and influence the selection of managers.
Third, small and medium-sized enterprises have a
poor ability to resist risks, and their business goal is
mainly to maximize short-term profits. For the sake
of enterprise survival, major shareholders are
unwilling to hire a technology CEO with high
salaries to enhance the long-term value of
enterprises. However, the competitiveness of stocks
and products of small and medium-sized companies
is weak, and it is difficult for them to grow if they
are excessively conservative in management. Small
and medium-sized enterprises should hire a
technical CEO, improve product quality, and
quickly occupy the market, just like Apple
company. They should attach importance to
products and innovation from the beginning, and
achieve the goal of quickly occupying the market.
The research conclusions of this paper may not
apply to foreign SMEs, because there are great
differences in traditional culture, capital market
development, and economic level. These
conclusions of this paper also do not apply to
China’s state-owned enterprises, which are subject
to government interference in major decisions.
6.2 Policy Recommendations
According to the research conclusions of this paper,
this paper puts forward the following suggestions to
improve the innovation level of small and medium-
sized private enterprises in China.
Regarding major shareholder governance, the
suggestions are as follows. First, enterprises can
cultivate a group of major shareholders with
innovative consciousness. The urgent task is to
cultivate a group of rational major shareholders with
innovative consciousness. These entrepreneurs can
lead team members to actively invest in innovation,
form a culture of enterprise innovation inside and
outside the company, and influence the behavior of
employees imperceptibly so that all employees can
make efforts towards innovation. Major
shareholders of enterprises should have a sense of
the overall situation and take the initiative to assume
the social responsibility of rejuvenating the country
through innovation, instead of blindly pursuing
profit maximization. They should not excessively
interfere in the decision-making of various
departments of the enterprise but should trust and
appropriately authorize all departments. Second,
enterprises can give play the supervisory role of
Party members over major shareholders. The
standard, sound, and independent three-tier
governance structure can promote the cooperation
and supervision of various departments and
maintain the normal and efficient operation of the
company. But the independence of the three-tier
institutions is vulnerable to interference by major
shareholders. Therefore, Party members can be
appointed to supervise the major shareholders of the
enterprise, encourage the controlling shareholders to
rationally allocate limited enterprise resources to the
production field, focus on the innovation ability of
the enterprise, and make the capital increase in the
production.
Regarding manager selection, the suggestions are
as follows. First, enterprises can improve the
employment mechanism of technical executives. As
the world’s largest developing country, China has
yet to complete its legal system, market-oriented
system, and modern enterprise management system,
and corporate governance is still immature and at a
relatively low level. It is common for management
to speculate and short-sighted behaviors that harm
shareholders and the long-term development of
enterprises. The short-sighted behaviors of
managers who pay more attention to short-term
profits rather than the long-term development of
enterprises lead to increased distrust of managers by
shareholders, which seriously affects innovation
activities. The introduction of external or internal
technical CEOs can effectively improve the
diversity of the management, reduce the short-
sightedness of the enterprise management, and
facilitate the management to take strategic decisions
in line with the long-term development of the
enterprise. Second, enterprises can improve equity
incentive measures for technical CEOs. This paper
finds that equity incentives can significantly
promote technical CEOs to increase innovation
investment. The key to improving the technological
innovation level of enterprises is to motivate the
technical staff to give full play to their intelligence.
The technical CEO is the leader in implementing
enterprise technology innovation activities. The
implementation of equity incentive measures for
technical CEOs can not only give full play to the
leading role of technical CEOs but also convey to
the market the signal that enterprises are actively
engaged in technology, which is conducive to access
to innovation resources and improve the innovation
level of enterprises.
