Research On The Impact Of Additional Deduction Policy On R&D Input Of Software And Information Technology Service Industry

With the progress of modern science and technology,innovation has become the first driving force leading development.Twenty ten reports pointed out to strengthen the main position of enterprise science and technology innovation,and R & D investment is the most basic and core link of enterprise innovation.Software and information technology service industry as a national strategic industry,to promote China’s economic and social development and achieve scientific and technological self-sufficiency and self-improvement has an important role.As an important subject of R&D and innovation,the R&D and innovation activities of software and IT service industry are of great significance to the overall innovation level of the country.At the same time,taxation is closely related to the production and operation of software and information technology service industry enterprises,and has a certain influence on the strategic choices and major decisions of enterprises.As an important tax policy,the policy of R&D expense deduction is an important focus point for the state to stimulate enterprises to increase their R&D investment and encourage their innovation.Therefore,the topic of this thesis is of great practical significance to promote the long-term development of China’s software and information technology service industry.The main part of this paper firstly analyzes the theoretical impact of the policy of R&D expense deduction on enterprise R&D investment and puts forward the hypothesis of this paper.Then,it analyzes the current situation of China’s R&D expense add-on deduction and China’s software and information technology service industry.Based on the theoretical analysis and the current situation analysis,this paper conducts an empirical test and constructs a model for regression analysis with the data of listed companies in software and information technology service industry from 2015-2020 as samples to study the impact of R&D expense-plus deduction policy on R&D investment of enterprises in software and information technology service industry from two perspectives,namely R&D capital investment and R&D personnel investment.The regression results show that the policy of R&D expense deduction will stimulate enterprises to increase their R&D capital investment and R&D personnel investment.At the same time,heterogeneity analysis is done for enterprises of different sizes in software and information technology service industry.The empirical results show that the incentive effect of the R&D expense deduction policy differs for enterprises of different sizes,and the incentive effect is better for small-sized enterprises.Then,a one-period lagging approach is used to test the robustness of the findings of this paper,which shows that there is a lagging effect of the policy on the R&D capital investment of software and IT service industry enterprises.Finally,based on the results of the theoretical and empirical analyses combined with the problems in the implementation of the R&D expense deduction policy,feasible suggestions are put forward.This paper argues that we should firstly start from the policy itself,optimize the R&D expense deduction policy,adopt a differentiated R&D expense deduction policy,and optimize the scope of application and accounting methods of the R&D expense deduction policy.At the same time,the support for SMEs should be strengthened,and finally,suggestions for improvement should be made from three perspectives: taxation authorities and government departments as well as enterprises themselves.
