[Abstract]:After ten years of gestation, China's GEM market was finally born in October 2009. By March 1, 2012, 291 enterprises had listed on the GEM, and began to become a new force in China's capital market. The rapid development of GEM has made the listed companies on GEM become the focus of attention. After that, the ownership will be gradually dispersed, the ownership and management rights will begin to separate, the agency relationship between shareholders and management will be highlighted, and the agency problem will also arise. Therefore, it is more and more important to evaluate the performance of the enterprise rationally. Note which factors have an impact on the performance of these GEM listed companies. According to previous research experience, the ownership structure of enterprises is a hot issue in the study of influencing factors of corporate performance.
Domestic scholars mainly study the relationship between ownership structure and corporate performance of Listed Companies in the main board market or listed companies on the small and medium-sized board. The biggest difference between GEM listed companies and the main board market is that the proportion of senior managers is very high. The first largest shareholders are natural shareholders or legal shareholders ultimately controlled by natural persons, and these natural individuals are senior managers in the enterprise, enterprises. The interests of large shareholders are consistent with those of senior managers.
This article will select 153 companies listed on the Shenzhen Stock Exchange before the end of 2010 as the research sample. The whole article is divided into two parts: the first half of the article, first of all, the theoretical basis of the ownership structure - principal-agent theory and stakeholder theory are expounded, expounding how the ownership structure through the enterprise. The governance structure plays an important role in the performance of enterprises, and finds relevant literature both at home and abroad. This paper reviews the existing research literature from the perspective of equity nature and equity concentration. Then, it introduces the characteristics of equity structure of GEM and listed companies on GEM, as well as the stocks of main board and small and medium-sized board enterprises. In the second half of the article, we use the empirical analysis method, select the substitution index of the ownership structure as the independent variable, select the substitution variable of the company's operating performance as the dependent variable, collect the data of the sample companies, and through the construction of a model for descriptive analysis, correlation analysis and regression analysis, point out the listing of GEM. What is the causal relationship between the characteristics of the equity structure and the operating performance of the listed companies on the GEM? At the end of the paper, the author puts forward relevant policy recommendations and points out the shortcomings of this paper.
This paper draws the following conclusions through empirical study.
1. There is a weak negative correlation between state-owned shares and the performance of GEM companies, but the coefficient has not passed the significant test: theoretically, the inefficiency of state-owned shares participating in corporate governance makes the proportion of state-owned shares negatively correlated with corporate performance. In GEM listed companies, because the proportion of state-owned shares is very small, the proportion of state-owned shares is very small. It does not have a significant impact on the company performance of the GEM listed companies.
2. The relationship between corporate shares and the performance of GEM is not obvious. On the one hand, compared with state-owned shares, corporate shares use their own capital. In order to increase the value of their investment capital, these corporate shareholders have the motivation to supervise the behavior of managers of enterprises. Compared with natural shareholders, corporate shareholders are more rational. On the other hand, these corporate shareholders still seek to maximize their own interests rather than the interests of listed companies, so corporate shareholders may engage in activities beneficial to themselves but harmful to the interests of listed companies. However, it will bring negative effects to listed companies and offset the positive effects of corporate shareholders on corporate performance. Because of the positive and negative effects of corporate shareholders, the test results are not significant.
3. There is a significant positive correlation between the executive stock and the performance of GEM: the senior managers are an important force for the development of the enterprise, whether the senior managers work hard or not is related to the performance of the enterprise. Shareholders'interests are bundled together, and the adoption of this equity incentive mechanism can make them pay attention to the long-term development of the enterprise, which is conducive to the improvement of the performance of the enterprise; moreover, many of the shareholders of the listed companies on the GEM are senior managers of the enterprise, and the interests of these controlling shareholders are one of the interests of the enterprise. Of course, of course, we are willing to do our best to improve the company's performance.
4. there is a significant negative correlation between circulating shares and operating performance of GEM companies.
Most of the holders of tradable shares are individual shareholders, and their distribution is extremely scattered. These tradable shareholders have the phenomenon of "hitchhiking". They have neither enthusiasm nor ability to participate in the governance of enterprises. The increase of the proportion of tradable shares in enterprises means that the degree of decentralization of the enterprise's equity becomes greater, and the decentralized ownership structure arrangement will produce. There are two problems: one is that the shareholders'supervisory ability to the managers of the enterprise will be weakened, the other is that the shareholders' enthusiasm to supervise the managers of the enterprise is also weak, so it has a negative impact on the business performance of the enterprise.
5. ownership concentration is positively related to the operating performance of GEM companies.
On the one hand, when the proportion of major shareholders increases, the tightness of the combination of the interests of the major shareholders and the interests of the company will increase, and the good and bad management of the company will play a great role to the major shareholders of the company. At this time, because of the convergence of the interests of the major shareholders and the interests of the company, the major shareholders will have more incentive to supervise and manage and effectively solve the problem. On the other hand, in our GEM enterprises, the first largest shareholder often plays the role of manager and presides over the daily affairs of the enterprise, because he personally assumes the role of manager will be greatly reduced because of the separation of shareholders and managers. And the length of the principal-agent chain avoids the problem of principal-agent. Because the manager is the owner of the enterprise at this time, the two are essentially unified, so the goal they are pursuing at this moment is the same. In this case, the shareholders of the enterprise do not need to deliberately supervise the various acts of the supervisor, because of common interests. Driven by profit, managers will consciously pursue the maximization of shareholders'interests, which is conducive to improving the performance of enterprises.
Looking at the above research, this article has its own characteristics in the following aspects:
1. The paper chooses a new angle of view. As the GEM has just been established in China's capital market for a short time, it is an emerging sector of China's capital market. Up to now, many domestic scholars have not studied the relationship between ownership structure and corporate performance, and most of them have focused on the Shanghai and Shenzhen main board. This study is based on many existing literatures at home and abroad, choosing the listed companies on the GEM as the research perspective, studying the ownership structure of the listed companies on the GEM. The relationship between ownership structure and operating efficiency and performance of GEM listed companies, on the one hand, is a supplement to previous studies, on the other hand, it also provides some empirical data for the optimization of ownership structure of GEM listed companies. Because the use of Tobin Q must have a prerequisite, that is, the capital market is effective, the price of assets can fully reflect all kinds of information, so the use of Tobin Q as a business performance measurement index of foreign literature, such as: Morek, Shleifer and Vishmy (1988), McConnell and Servae (1990), and so on. Some domestic scholars are also Tobin Q value is used as the research variable (Sun Yongxiang, Huang Zuhui (1999), Zhang Hongjun (2000), Yu Xiaoming (2003). However, this paper argues that the development of China's capital market is not sound, the use of Tobin Q value to measure the performance of enterprises seems inappropriate, this paper uses financial accounting indicators, many domestic scholars are using financial accounting. Chen Xiao, Jiangdong (2000) used the return on net assets and the profit margin of the main business to represent the business performance of enterprises, Wu Shukun (2002) used the total asset profit margin to measure the business performance of enterprises, Wei Le (2010) used the main business profit margin index, Wang Ling (2010) used the return on net assets (ROE), core business assets. Based on the GEM perspective, this paper uses the earnings per share (EPS), which reflects the overall profitability of the enterprise, as the company's operating performance, and from the perspective of financial management, uses the net cash per share of the enterprise's operating activities. Flow (CPPS) is another alternative indicator of company performance. The reason why we choose this indicator is that the net operating cash flow per share can reflect the ability of enterprise to earn cash flow. At the same time, asset-liability ratio and company size are moderately introduced into the model as control variables.
3. Considering the particularity of the ownership structure of the listed companies on the GEM, this paper does not divide the ownership into state-owned shares, legal person shares and circulating shares directly as previous scholars (Chen Xiao, Jiangdong (2000)). From the latter statistical analysis, we can see that the proportion of senior executives in the main board market is only 0.74%, small and medium-sized. The proportion of senior managers holding shares is 12.83% in the listed companies on the board, but the proportion of senior managers holding shares in the listed companies on the GEM is as high as 32.07%. The proportion of senior managers holding shares has a very significant correlation with the company's performance. Therefore, the index of senior managers holding shares is added to the board, and the other three indicators are used as an alternative variable of ownership structure. As for the index selection of ownership concentration degree, this paper does not regard Z index as the index of ownership checks and balances (Fan Lihong (2007), Chen Deping, Chen Yongsheng (2011), but as the substitute variable of ownership concentration degree together with CR1 index and H5 index, and draws the conclusion that Z index and GEM listed companies. Performance has a weak positive correlation.
