[Abstract]:With the development of capital market in China, insider trading of listed companies is gradually active. However, insider trading in listed companies may be transformed into insider trading under the condition of lax supervision. Illegal insider trading and insider trading have adverse effects on listed companies, external investors and securities market, so it is urgent to study and standardize the management of insider trading. Based on the study of the insider trading data of listed companies published by Shanghai and Shenzhen Stock Exchange since 2006, this paper first analyzes the present situation of insider trading, then verifies the influencing factors of insider trading, and finally investigates the experience and shortcomings of insider transaction management in China, and on the basis of the above conclusions, puts forward some effective measures for the standardized management of insider trading in listed companies. In this paper, it is found that the frequency, scale and market value of insider transactions in listed companies are large, and there is an upward trend year by year. The situation of insider collective trading is obvious, the behavior of insider relatives trading is significant, short-term trading, sensitive period transactions are more, and the postponement announcement behavior after insider share changes is common. In addition, it is found that information power is the basis of insider trading profit of listed companies, excess income is direct motivation, information disclosure affects the choice of profit strategy, insider position affects transaction content, perfect corporate governance environment, strict transaction supervision and good legal environment can effectively prevent the occurrence of insider illegal trading behavior. Finally, the effective measures for the standardized management of insider transactions of listed companies are put forward from four aspects: autonomy of listed companies, intermediate organizational supervision, national legislative regulation and market participation supervision. The paper mainly has the following two innovations: first, the insider transaction of the listed company still occupies the dominant position of the insider transaction; second, for the first time, it puts forward three measures to standardize the management of the insider transaction: the automatic locking illegal trading account method, the pre-transaction announcement system and the insider property declaration system of the listed company. Automatic locking of illegal trading account is a new method to prevent illegal trading by locking illegal insider trading account in time; pre-transaction announcement system is a kind of prior declaration system of insider transaction; and insider property declaration system of listed company is a new method to control insider illegal transaction by supervising the source of insider property. Generally speaking, this paper makes a comprehensive analysis of the situation and influence of insider transactions of listed companies, and puts forward some new measures for the standardized management of insider transactions of listed companies, however, it still needs to be tested in practice.
