In this thesis, we introduce three indexes that are used to evaluate the main business firstly. Theyre 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.
