Research On The Impact Of Enterprise Income Tax Preferential Policy On Enterprise Innovation Efficiency

Technological innovation is the core of the national development strategy and the inexhaustible motive force for ensuring rapid economic growth.Nowadays,technological innovation has increasingly become the focus of national competition.China needs to increase its emphasis on technological innovation under the trend of world economic development.Economic and social sustainable development.The report of the 19 th CPC National Congress has pointed out that innovation is the first driving force for development and the strategic support for building a modern economic system.This theory gives the innovation a new historical position in the development strategy.Only by adapting to the new era and new requirements can we give full play to the strategic support role of innovation in building a modern economic system.In the road to innovation,China needs to stimulate the innovation vitality of the whole industry,strengthen the construction of basic research,create a social development environment based on innovation,promote institutional innovation through comprehensive deepening reform,and remove the institutional barriers that restrict the independent innovation of market players.Effectively stimulate the vitality and enthusiasm of independent innovation of market players.Enterprises will face technological R&D risks,technology design risks,and technology application risks when they are engaged in independent innovation.At the same time,they will bear the high cost of R&D costs.The government can indirectly help enterprises reduce R&D costs through taxation policies,and guide enterprises to increase the Strength of R&D investment,and to a certain extent,promote the technological innovation capability of enterprises.However,in the fierce and innovative competitive environment,the improvement of R&D capability brought by high investment does not fully reflect the core competitiveness of the enterprise.More is to ensure high output while high investment,so objectively evaluate enterprise innovation.Efficiency is of great significance,and at the same time,at the government level,how to guide through taxation policy is also crucial.Based on the literature review and theoretical analysis,this paper adopts the SFA method,selects the data of 97 CGEM listed companies from 2011 to 2017,by measuring the innovation efficiency by using the number of patent applications as the output variable,the number of R&D personnel and R&D expenditure as the input variables,and measuring the average level of innovation efficiency of enterprises in China,the actual tax rate is used as an indicator to measure the preferential policies of corporate income tax,verify the impact of corporate income tax incentives on the efficiency of innovation;According to the regional classification of samples in the eastern coastal areas and non-coastal areas,observe the differences in innovation efficiency levels between different regions and how the corporate income tax incentives have different effects in promoting innovation efficiency.R&D found that the overall level of innovation efficiency of enterprises is not high at present,but with the passage of time,the efficiency of innovation shows an upward trend,indicating that there is still room for improvement in the overall situation;.The corporate income tax preferential policy has a negative impact on the efficiency of enterprise innovation,and the impact effect is significant;In addition,the input of R&D personnel and R&D expenditure has a significant positive impact on innovation output.The net increase in fixed assets and government subsidies have a significant positive impact on innovation efficiency,the size of the firm has had a significant negative impact on innovation efficiency.From the perspective of regional subdivision,the innovation efficiency of the eastern coastal areas and non-coastal areas is quite different,and the average value of innovation in the eastern coastal areas is significantly higher than that of non-coastal areas;the current income tax preferential policies have a negative impact on the innovation efficiency of enterprises in the eastern coastal areas.The current income tax preferential policies have a negative impact on the innovation efficiency of enterprises in the eastern coastal areas,while the impact on non-coastal areas is not significant;the net increase in fixed assets and government subsidies have a significant role in promoting the eastern coastal areas and non-coastal areas.
