【摘要】：本文在国内外公司避税问题越来越突出的背景下，主要研究上市公司股权结构及公司所处的地区市场化进程差异是否会导致公司所得税避税行为恶化这样的一个问题，在分析国内外相关研究的基础上，，通过信息不对称理论、委托代理理论以及税收筹划理论建立了股权结构、市场化进程水平与所得税避税程度关系的理论模型，并通过实证研究证实了本文关于股权结构与企业所处的市场化进程对上市公司所得税避税关系的论断。本论文中股权结构主要以上市公司股权性质、股权集中度、股权制衡度以及其中的交叉关系来衡量，对于市场化进程以政府监管力度来衡量研究以上几者与企业所得税避税程度的关系。对于企业所得税避税程度的度量是本文中的一大重点以及难点，综合国内外关于避税的研究，本文最终决定利用实际所得税税率来衡量企业的避税程度。通过本文的研究，得到的主要结论有：（1）我国上市公司确实存在所得税避税行为，且存在行业差异。在行业上，表现为税收优惠越少的行业越倾向于采取较激进的避税措施。（2）股权集中度与企业所得税避税程度正相关，并且受到股权类型的影响。（3）股权制衡度与企业所得税避税程度正相关，也受到股权类型的影响。（4）上市公司高管持股比例与企业所得税避税程度正相关。（5）市场化进程与企业所得税避税程度负相关。上市公司所得税一直都是我国税收的主要来源，近几年，随着我国经济不断的快速发展，税收流失率也一直高居不下，影响着我国的财政收入，从而影响我国宏观调控能力与资源配置有效性。通过本文的研究，可以有效地为税务部门在税收征收管理制度层面提出建议，减少企业不合理地避税行为。
[Abstract]:Under the background of domestic and foreign companies' tax avoidance problem becoming more and more prominent, this paper mainly studies whether the differences in the ownership structure of listed companies and the regional marketization process of companies will lead to the deterioration of corporate income tax avoidance behavior. Based on the analysis of relevant research at home and abroad, this paper establishes a theoretical model of the relationship between equity structure, the level of marketization process and the degree of income tax avoidance through information asymmetry theory, principal-agent theory and tax planning theory. Through the empirical research, this paper confirms the conclusion of the relationship between the ownership structure and the marketization process of the listed companies on income tax avoidance. In this paper, the equity structure of listed companies is mainly measured by the nature of equity, the degree of ownership concentration, the degree of equity checks and balances, and the cross-relationship among them. This paper studies the relationship between the above mentioned factors and the degree of corporate income tax avoidance. The measurement of the degree of corporate income tax avoidance is one of the key points and difficulties in this paper. Synthesizing the domestic and foreign research on tax avoidance, this paper finally decides to use the actual income tax rate to measure the degree of corporate tax avoidance. The main conclusions are as follows: (1) China's listed companies do have income tax avoidance behavior, and there are industry differences. In the industry, the industries with less tax preference tend to take more radical tax avoidance measures. (2) the degree of equity concentration is positively related to the degree of corporate income tax avoidance. And affected by the type of equity. (3) the degree of equity balance and corporate income tax avoidance degree is positively related, (4) the proportion of stock ownership of listed companies is positively related to the degree of corporate income tax avoidance. (5) the marketization process is negatively correlated with the degree of corporate income tax avoidance. The income tax of listed companies has always been the main source of tax revenue in our country. In recent years, with the rapid development of our economy, the rate of tax revenue loss has been high, which has affected the financial revenue of our country. This will affect the ability of macro-control and the effectiveness of resource allocation. Through the research of this paper, we can put forward effective suggestions for tax departments in the level of tax collection and management system, and reduce the unreasonable tax avoidance behavior of enterprises.
