| The problems that the reinvestment of listed companies loses the balance of assets structure and the efficiency of assets become more and more serious, which are caused by the unreasonable distribution of resources. In fact, the indexes that are used to evaluate the operation achievement of main business affect the enterprises' direction and continuity of development.In this thesis, we introduce three indexes that are used to evaluate the main business firstly. They're profit of main business, cashflow of main business and integrated index of main business. Then, we construct a series of regression models of assets structure with profit of main business and cashflow of main business, which signalize the current assets and the fixed assets help them; the long-term investments hinder them; the other assets help or hinder them uncertainly, and even have nothing to do with them sometimes. Finally, we construct the regression models of assets structure with integrated index of main business, and put forward a method to optimize the assets structure.We do empirical analysis of the relationship between the assets structure and the operating capacity of the listed companies in this thesis, therefore, we could know more about the relationship between assets structure and operating capacity, and provide beneficial policies and suggestion in order to strengthen management for operator, investor and other stakeholders. |
