| Tax reduction and fee reduction are the government’s policy means to accelerate supply side reform and promote the transformation and upgrading of macroeconomic structure.Innovation driven is the core strategy of China’s economic development in the coming period,which has a bearing on the overall improvement of the quality of market micro subjects and the realization of the goal of macroeconomic structure transformation and upgrading.Small and medium-sized manufacturing enterprises are the key support objects of the tax reduction and fee reduction policy,and also the main force to realize technological innovation.This paper focuses on the impact of tax reduction and fee reduction on the technological innovation performance of small and medium-sized manufacturing enterprises.This paper introduces in detail the relevant background,research status,main concepts and basic theories of tax reduction and fee reduction and technological innovation of small and medium-sized manufacturing enterprises,and carries out basic relationship research assumptions and heterogeneity research assumptions.The basic relationship assumptions include tax reduction and fee reduction and enterprise technology R&D input and output,and the relationship between tax reduction and fee reduction and technological innovation is affected by different taxes.The heterogeneity assumptions include regional characteristics,property rights characteristics and market characteristics.In terms of data sample selection,8096 pieces of panel data of 758 manufacturing SMEs from 2010 to 2021 are selected to construct a multiple linear regression model of panel data.There are two explanatory variables:technology R&D investment and patent authorization.At the end of the paper,the research situation of the whole paper is summarized,and four policy implications are put forward,and the business trend and research mode of the future tax reduction and fee reduction and technological innovation of small and medium-sized manufacturing enterprises are preliminarily prospected.The main conclusions of this paper are:first,tax reduction and fee reduction are positively related to the R&D investment of manufacturing enterprises,that is,the more policies enterprises enjoy,the greater the amount of R&D investment.Different tax categories have different incentive effects on technological innovation of enterprises.The positive incentive effect of value-added tax is greater than that of income tax.The partial regression coefficients are 0.423 and 0.262,respectively.The former is 38%higher than the latter;Second,in the process of the impact of tax reduction and fee reduction on the development of enterprise technological innovation.there are heterogeneity in three aspects:regional characteristics,marketization degree characteristics and property rights characteristics.In comparison,the eastern region,private enterprises and high-tech enterprises are more encouraged by the tax reduction and fee reduction policy;Third,different indicators to measure technological innovation of small and medium-sized manufacturing enterprises have different effects on the implementation of tax reduction and fee reduction policies.Therefore,a set of scientific and comprehensive performance evaluation standards for technological innovation should be established to provide a basis for comprehensively evaluating the implementation effect of tax reduction and fee reduction. |
