Research On The Influence Of Preferential Tax Policy On The R&D Investment Of High-Technology Enterprises

Since the Twenty-first Century,the world economy has been developing rapidly,and technology is becoming a powerful driving force for economic development,all countries around the world focus on the innovation of science and technology in promoting economic development.The technological innovation capability of enterprises can be embodied by the investment of Research and Development(R&D)to a certain extent.Tax revenue as a significant method to regulate the macro economy by the government,various countries continue to publish scientific and technological incentive policies to promote the benign development of the enterprises.Since 1980 s,our country has continually published numerous preferential tax policies especially in terms of preferential income tax policies to motivate enterprises' investment on R&D.High-technology enterprises are the main force in the technological innovation and scientific research investment,and China has strongly supported high-technology enterprises during these years,and has published a series of preferential tax policies for high-technology enterprises.A comprehensive analysis of China's current preferential tax policies for high-technology enterprises and quantitative research of its implementation effect will help improve the related preferential tax policies and promote the innovation capacity of high-technology enterprises,which owns great theoretical meaning and practical value.This article first introduces the research background,the current domestic and international research situation and the proposed research methods.Secondly,it explains the relationship between R&D investment and economic growth,the economic basis of tax preference and the implementation effect of R&D preferential tax policy theoretically.Then it analyzes the related R&D preferential tax policies and the current situation of high-technology enterprises R&D investment in China.Thirdly,it establishes the analysis model and research hypothesis,and taking the high-technology enterprises in Jinshan District of Shanghai as examples,using regression analysis and other analysis to research the implementation effect of preferential tax policies on enterprise R&D investment.The results of empirical analysis show that there is a positive correlation between preferential tax and R&D investment and the number of researchers in high-technology enterprises,and there is no significant correlation with R&D investment intensity,R&D researchers intensity and number of patent applications;the investment of enterprise R&D will increase by 0.441 when the tax preference amount is increased by 1;In terms of tax classification,the income tax preference promoting effect is more obvious than the VAT preference;in terms of the preferential method,the high-technology enterprise income tax deduction promoting effect is more obvious than the R&D cost deduction.Finally,in view of current policies and its existing problems in implementation,put forward some improvement suggestions.
