Study On Replacing Business Tax With VAT Policy's Effect Of Transportation Industry Based On DID Model

Replacing business tax with VAT as an important part of the fiscal and taxation system reform in our country,in order to reduce short-term fiscal revenue for the development trend of continued growth,the steady development of our country's economy is of great significance,also for the structural reform of the power supply efficiency.Review test at the beginning of the reform,the overall tax effect is obvious,but the transportation average taxpayer's tax burden is not reduced but increases,some scholars put forward this kind of phenomenon is not unusual,with the passage of time,the reform of the dividend will be gradually released,namely the impact of policy may have certain hysteresis quality.Although the analysis of replacing business tax with VAT has a lot of papers,but the impact of policies on the industry tax burden and performance has not formed yet,further research on hysteresis quality were not recorded in the domestic and foreign literature.VAT reform has been for 5 years,this paper uses the DID model method is currently one of the mainstream international econometric community,continue to study transportation VAT tax policy effect,to verify the expected lag effect exists,the review of the current transportation tax reform has been achieved.The reason of using this method is that it can avoid the interference of other synchronic factors which can not be excluded in the research,and get the net causality inference of the policy.Firstly,the paper classifies the Chinese and foreign literatures of the transportation industry,in order to avoid the limitations of the existing research methods and establish the mathematical model used in this paper.Secondly,the transportation industry in the current operating state,different definition of taxpayer identity,based on expounding the theory and performance evaluation of tax system,selected comprehensive evaluation index system,respectively,from the four aspects of corporate profitability,operating capacity,solvency and development ability to find out the specific policy of replacing business tax with VAT through which financial index of the burden of enterprises and affect the performance,according to the characteristics of business tax and value-added tax,the impact factor calculation of equilibrium critical value and turnover tax burden changes the amount of corporate tax changes on the overall amount of tax changes.The part of empirical research in selected 58 transportation companies listed in Shanghai and Shenzhen as a sample,gathering enterprise 2010-2016 panel data,using multi index evaluation system,through principal component analysis to reduce the dimensionality,establish DID model for variable to the overall tax burden rate of sample enterprises and comprehensive performance,through the two time difference are replacing business tax with VAT net effect of general tax impact on the transportation industry,conclusion is the expected hysteresis qualityis does exist,replacing business tax with VAT influence on enterprise reform in early years was the most obvious,has negative effect,after getting better year after year.Finally,aiming at the problems in the process of camp reform,this paper puts forward specific countermeasures.
