现行实际所得税率的行业地区差异及经济影响

The Industrial and Regional Differences of Effective Income Tax Rate and The Economic Consequences

2008年1月1日实施《中华人民共和国企业所得税法》,目的是实现税制公平,改善税收优惠政策等。新税法实施以后,内外资上市公司所得税制度是否真的实现了公平,不同行业、地区的上市公司实际税率(ETR)是否存在差异,市场是否会对ETR的差异作出正面的积极的反应,诸多问题亟待检验。本文选取2008年A股非金融类的上市公司作为研究样本,用实证的方法研究上述问题,得出结论:我国上市公司确实实现了内外资企业所得税制度的公平,ETR在不同行业和地区之间确实存在差异,市场对ETR较低的公司也做出了正面反应。

The implementation of the ＂PRC Enterprise Income Tax Law＂ in 2008 aims at achieving a fair tax system,improving the tax incentives.After the implementation of the new tax law,have foreign-invested and domestic listed companies achieved equity in income tax？ Is there any difference of the effective tax rate（ETR） of listed companies in different industries and regions？ Could the market make positive response to the differences between ETRs？ So many issues need to be tested.This paper selected non-financial listed companies of class A shares in 2008 as the samples,studied the issues with empirical method and reached the conclusions： Chinese listed companies have achieved fairness in income tax system within foreign-invested and domestic listed companies;ETR differences do exist in different industries and regions;the market has already made positive responses to the companies with lower ETR.
