The Study On The Chinese Government Fiscal Costs And Income Quantification Of The Tax Deferred Pension Insurance

Based on the social and economic data of Sichuan Province in 2015,this paper quantitatively analyzes the effect of chinese government fiscal costs and income quantification of the tax deferred pension insurance by establishing a tax expenditure model and substitute rate model under different parameter hypothesis,such as the average growth rate of wages and the investment yield.According to the results of the model calculation,the substitute rate of the tax deferred pension insurance in Sichuan Province is generally between 2% and 5%,which is far less than the expectation of 10% of the substitute rate.The main reason is the insufficient payment and the low return on investment;The government's financial costs is proportional to insurance time and average wage;If the policy of 2400 yuan every year limit deferred tax incentives is implemented,the first year of the Sichuan provincial government tax will be 16.071 to 482.12 billion yuan,the proportion of which is less than 1% of the present value of fiscal revenue,that is to say,there is very little impact on the local fiscal policy;In Sichuan Province,the eligible currently uninsured'tax expenditure of the present value is RMB 32.141 billion,from the age of 30 to 60,the present value of fiscal expenditure accounts for only 0.198% of the tax present value and the present value of fiscal revenue 0.011%,all the ratio of is less than 1%,which shows that Sichuan has sufficient fiscal revenue to support the development of preferential tax policies.Finally,the paper puts forward the policy of adjusting the amount of preferential tax,implementing the discriminating discount policies for main body of different incomers and different economic groups with different economic development levels,supervising the various insurance companies strictly,setting a certain insurance credit grading system.
