营改增对煤炭企业经营绩效的影响

Study on Impact of Replacing BT with VAT on Business Performance of Coal Enterprise

营改增是我国1994年分税制改革以来财税体制的又一重要变革,对作为我国能源主体的煤炭行业也产生了影响。选取2012年～2016年煤炭行业上市公司数据,运用配对样本t检验方法,通过对煤炭企业营改增前后边际利润系数及息税前利润的弹性系数实证分析发现,营改增对煤炭行业经营绩效的影响弹性显著,对边际影响不显著。

As one of the important changes in the tax system since the tax-sharing reform in 1994,replacing the BT with the VAT has an impact on the coal industry, which is the main energy source of China. Takes the financial data of listed companies in the coal industry in 2012 to 2016, which is before and after the point of time when the pilot of replacing the BT with a VAT was carried out, as the basis, uses paired samples t-test to carries out the empirical research on both the margin of NP and the elasticity of EBIT. It is found that the margin is not significant but the elasticity is very significant on coal enterprise business performance.
