The research topic of corporate finance is

The research object of corporate finance is: corporate enterprises. Corporate finance mainly studies the financing, investment, income distribution and related issues of enterprises. It is a branch of finance, which is used to examine how companies can effectively use various financing channels, obtain the lowest-cost sources of funds, and form an appropriate capital structure; It also includes enterprise investment, profit distribution, working capital management and financial analysis. The theoretical research on corporate finance in China mainly stems from the reform needs of state-owned enterprises. Some people believe that the financial difficulties of state-owned enterprises are due to their heavy debts, that is, the capital structure is unreasonable. However, a more general view blames the inefficiency of state-owned enterprises on their unclear property rights and serious defects in corporate governance. Therefore, we should vigorously promote the shareholding system reform, improve the corporate governance structure and capital structure, so as to improve the efficiency of enterprises. From this point of view, a large number of literatures about corporate governance and corporate performance in China can be classified into the research category of corporate finance. The research in this field mainly uses the data of listed companies for empirical test, covering the company's capital structure, corporate governance, performance evaluation and information disclosure. For example, Zhang Yi and others have done research on the relationship between diversification and corporate performance of listed companies, while Wang Peng and Li Zhouan have done research on the relationship between control and ownership of controlling shareholders and corporate performance.
