我国A股上市公司管理层股权激励与公司绩效的关系研究
[Abstract]:The development of productive forces further refines the division of labor in society. Owners of enterprises do not possess the best strength of operating enterprises because of their knowledge, ability and energy. Professional division of labor produces a large number of agents with professional knowledge. They have the energy and ability to perform well the work entrusted by owners. Because the utility function of the principal and the agent is different, the principal pursues the maximization of his own wealth, while the agent pursues his own salary and income, and maximizes his in-service consumption and leisure time, which will inevitably lead to the conflict of interests between them. Finally, it will damage the interests of the principal, which is the root cause of the agency problem.
Management plays an important role in the separation of ownership and management rights of modern enterprises. Although they can not own the enterprise, they stand at the forefront of enterprise management decision-making. How to supervise and manage the shareholders and keep their behavior in line with the interests of shareholders is a common problem faced by all enterprises, because shareholders do not participate in the company day It is inevitable that there is information asymmetry between management and management, and the agency cost caused by moral hazard and adverse selection is inevitable. Equity incentive gives the management residual claim to the company's value, binds the interests of the management and the shareholders together, and establishes a positive correlation between the interests of the management and the company's performance. This can effectively stimulate the management's professionalism, reduce agency costs, and improve the company's management mechanism. And increase the performance level of the company.
Since the 1950s in the United States, equity incentive as a long-term incentive system for management and employees began to germinate in practice, in the early development of this incentive system did not cause widespread concern until the 1960s, the United States Silicon Valley, some of the high-tech, high-growth companies due to the early start-up stage. Lack of funds, under the pressure of maintaining the stability of the core personnel and ensuring the company's competitive edge, large-scale equity incentives were implemented to the core personnel such as management to retain outstanding personnel. In the following 1970s, the professional manager seller market was further strengthened and the mobility of senior personnel was increasing. This phenomenon also poses a threat to enterprises. At the same time, because equity incentive does not include accounting costs, it will not reduce the book profits of enterprises, so this incentive method is especially favored by innovative companies in the growing period and cash flow is tight. Therefore, equity incentive has rapidly developed into an important incentive for management in developed countries in Europe and the United States. Tools.
In order to improve business performance and improve governance structure, listed companies in China have learned from western experience and made active exploration in the management of equity incentives. However, due to the defects of market environment and institutional environment, equity incentives have faced many obstacles, especially the unique equity division in China's securities market, which has caused the capital of China. In this market, the state-owned shares are dominant, the proportion of circulating shares is small, and the stock price can not fully reflect the value of the company. Therefore, it is obviously lack of practical and logical support to encourage the management with equity. At the same time, the lack of market-oriented degree and the imperfection of corporate governance structure lead to the phenomenon that managers are appointed by the administration is more common. More concerned about their administrative status and other non-economic factors as well as whether they can fulfil the target task given by their superiors in full, and are unwilling to take risks, although these risks may bring enormous benefits to the enterprise, therefore, the implementation of equity incentives for such managers can not achieve the desired results. The implementation of the split share structure reform in 2005 is the top priority. The implementation of equity incentive in listed companies has created favorable conditions. In December 2005, the SFC promulgated the Measures for the Management of Equity Incentive in Listed Companies (Trial Implementation). The promotion of the regulatory authorities has become a stimulant to the implementation of equity incentive in Listed Companies in China. Since then, more and more listed companies have begun to implement corporate governance. The "golden handcuffs" are used in stock affairs.
The research on equity incentive abroad started very early and is relatively mature, so the relevant conclusions have a certain reference for this paper. However, due to the late start of China's capital market, the imperfect legal system and corporate governance structure, there is a big gap with the mature capital market system of western developed countries, foreign scholars in The conclusions drawn in the related fields of equity incentive can not be transferred to the market environment of our country. China is in the period of economic transformation. The implementation of "Management Measures" began in January 2006. The listed companies in our country began to implement equity incentive in real sense only at this time. At present, the relevant empirical research is limited, and the scholars in China have limited knowledge about equity. Whether incentive can really improve corporate performance has not yet reached a consensus.
The overall objective of this study is to examine whether the implementation of equity incentives by Listed Companies in China has a positive impact on corporate performance, and the time span of this impact. Before the reform of "management measures" and non-tradable shares, there are still many institutional and legal barriers to the implementation of equity incentives. The proportion of managerial ownership is the same as that of equity incentive, and it is after 2006 that listed companies in China begin to implement equity incentive in a real sense. So there are not many literatures about equity incentive in China. This paper selects 138 A-shares listed companies in Shanghai and Shenzhen stock markets which implemented equity incentive plan from 2006 to 2009. As a sample, the company examines the impact of managerial equity incentive on corporate performance in real sense.
The structure of this article is as follows:
The first chapter, the introduction part, this chapter elaborated the management stock right incentive topic background; The research significance, the mentality and the method.
In the second chapter, literature review, this chapter first expounds four classical theories related to equity incentive, such as principal-agent theory, and then elaborates two hypotheses related to equity incentive effect: interest convergence hypothesis and managerial defense hypothesis. Summary and comment.
In the third chapter, the concept of management equity incentive is expounded, the advantages and disadvantages of various equity incentive modes are compared, and the development of management equity incentive in China is reviewed as a whole.
In the fourth chapter, the empirical part of managerial equity incentives, this chapter chooses 138 A-share listed companies in Shanghai and Shenzhen from 2006 to 2009 which have implemented equity incentive plans as samples, and studies the relationship between performance and equity incentives of A-share listed companies in China by constructing a multiple regression econometric model. The ROE of listed companies adjusted by industry mean is taken as the example. As a dependent variable, ROE with a lag of 0 years, 1 year, 2 years and 3 years is comprehensively investigated in order to comprehensively analyze the time lag of the impact of equity incentives on corporate performance. The model chooses SRAT and its square SRAT2 as independent variables, and controls the choice of corporate nature, ownership concentration and equity checks and balances. This paper studies the relationship between equity incentive and corporate performance.
In the fifth chapter, the results of the empirical study are summarized as follows: (1) management equity incentives have time lag to improve corporate performance; (2) there is a "inverted U" relationship between management equity incentives and corporate performance; (3) ownership concentration, enterprise size and the proportion of supervisors in management are negatively correlated with corporate performance; (4) executive compensation and corporate performance are negatively correlated. The company's performance is positively correlated.
The main innovations of this paper are as follows: firstly, this paper comprehensively examines the time lag of equity incentive, which is different from the previous literature which only examines the ROE lagging behind 0 years and 1 year. This paper comprehensively examines the ROE situation with lag of 0 years, 1 year, 2 years and 3 years, and grasps the relationship between equity incentive and corporate performance from a longer time span, and it is empirical. The results also show that the delayed impact of equity incentives on corporate performance does exist, and it is longer than the one year generally believed, reaching 2 years or even 3 years; second, the data processing method used in this paper is better to integrate the samples of each year together, the sample is divided into 13 industries according to the industry classification standards of the SFC. The adjusted ROE reflects the unique ROE of a single enterprise, which is not affected by the factors of industry and year. It is only affected by the factors of the enterprise itself, because the A-share listed companies in China only opened after 2006. In the real sense of equity incentive, the sample size per year is small, which can be used to integrate the samples of each year to obtain better parameter estimates.
The shortcomings of this paper are as follows: Firstly, this paper examines the delayed effect of managerial equity incentives on corporate performance, but it does not further investigate what factors affect the variable of equity incentives, that is, there is no further discussion on the endogenous issues of equity incentives, the future author will try to stand in this perspective on equity incentives. Second, although this paper has adopted a reasonable way to integrate the sample data of each year, as the date of finalization of this paper, most of the annual reports of Listed Companies in 2011 have not been published, so the sample is slightly inadequate when investigating the impact of equity incentive delay, I believe that with the sample data become more and more abundant. Third, there are many factors that affect corporate performance. This paper may omit some important variables when choosing the explanatory variables. We hope that in the future research, we can choose the relevant variables more comprehensively to analyze in order to get better empirical results.
