【摘要】：企业税收负担是税收理论与制度的重要组成部分之一，税收即宏观地影响着国家财政收入情况，又决定着企业承受负担的大小。公平合理的税负比例，既能保证国家财政收入提供公共服务的需要，又能促进经济环境的公平有效，促使企业走上良性发展的道路。近年来，我国税制不断的改革发展并日趋完善，本文将研究在这样的大环境下，企业实际承担的税收负担情况以及其影响因素。本文选取2005——2012年在沪深两市上市的上市公司作为研究样本，分别进行描述性分析和多元线性回归分析，刻画上市公司实际税率基本情况、研究实际税率影响因素。通过描述性统计，笔者发现：上市公司实际税率总体低于一般名义税率，国有性质上市公司实际税率均值高于非国有性质上市公司，东部地区上市公司企业实际税率均值最高，中部地区次之，西部地区最低，不同行业上市公司实际税率也处在不同水平之上。另外，随着时间的推移，上市公司实际税率在逐年下降，各地区实际税率差异也在逐步减少。通过多元线性回归，得到如下结论：上市公司实际税率与实际控制人背景显著正相关；与国有股比例显著正相关；非国有上市公司实际税率与高管持股比例显著负相关，国有上市公司，则不存在这一显著相关性，但系数仍为负；税收征管强度与上市公司实际税率显著正相关，，且税收征管强度对非国有上市公司的影响比对国有上市公司的影响更大。另外，就企业基本特征而言，非国有上市公司实际税率与资产收益率显著正相关，国有上市公司则表现为显著负相关；与资产负债率、固定资产比率显著负相关，z盾效应明显；与总资产的自然对数显著正相关。
[Abstract]:Corporate tax burden is one of the important parts of tax theory and system. Tax affects the state financial revenue macroscopically, and determines the size of the burden borne by enterprises and the fair and reasonable tax burden ratio. It can not only guarantee the need of the public service provided by the national financial revenue, but also promote the fairness and efficiency of the economic environment, and promote the enterprises to take the road of benign development. In recent years, the tax system of our country has been continuously reformed and developed and become more and more perfect. In this paper, we will study the tax burden of enterprises and its influencing factors in such a big environment. This paper selects listed companies listed in Shanghai and Shenzhen stock markets from 2005 to 2012 as the research samples. Descriptive analysis and multiple linear regression analysis are carried out to depict the basic situation of the effective tax rate of listed companies and to study the influencing factors of the effective tax rate. Through descriptive statistics, the author finds that the effective tax rate of listed companies is generally lower than the general nominal tax rate, and the average effective tax rate of state-owned listed companies is higher than that of non-state-owned listed companies. The average effective tax rate of listed companies in the eastern region is the highest, followed by the central region, the lowest in the western region, and the effective tax rates of listed companies in different industries are also on different levels. In addition, with the passage of time. The effective tax rate of listed company is decreasing year by year, and the difference of effective tax rate among different regions is gradually decreasing. Through multiple linear regression, the following conclusions are obtained: the effective tax rate of listed companies is significantly positively correlated with the background of actual controllers; There is a significant positive correlation with the proportion of state-owned shares; There is a significant negative correlation between the effective tax rate of non-state-owned listed companies and the proportion of senior managers' shareholding, but the coefficient is still negative. The intensity of tax collection and management is significantly positively correlated with the actual tax rate of listed companies, and the impact of the intensity of tax collection on non-state-owned listed companies is greater than that on state-owned listed companies. In addition, in terms of the basic characteristics of enterprises, the effective tax rate of non-state-owned listed companies is significantly positively correlated with the return on assets, while the performance of state-owned listed companies is significantly negative correlation. There is a significant negative correlation between the ratio of fixed assets and asset-liability ratio. There is a significant positive correlation with the natural logarithm of total assets.
