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.

本文首先将主营业务指标分为主营业务利润、主营业务现金流量与主营业务综合指标；然后，通过构建资产结构与主营业务利润、资产结构与主营业务现金流量回归模型，发现流动资产、固定资产对主营业务利润和主营业务现金流量为正影响，长期投资对主营业务利润和主营业务现金流量为负影响，其他资产对主营业务利润和主营业务现金流量影响时有时无，时正时负；最后，在此研究基础上，构建资产结构与主营业务综合业绩指标回归模型，并提出优化资产结构的方法。
