Research On The Impact Of Corporate Income Tax Preferential Policies On R&D Innovation Of High-tech Industry

Since the 11 th five-year plan,high-tech industry,as one of the key strategic industries supported by our country,is based on scientific and technological innovation,constantly improving the ability of independent innovation,enhancing the core competitiveness,and striving to make the high-tech industry bigger and stronger.At the same time,high-tech industry,as a key industry with high technology intensity in manufacturing industry,to a certain extent,its development also affects me.Transformation of China's manufacturing industry structure and transformation of economic growth model.From the current situation,the innovation level of China's hightech industry has increased significantly in recent years,but there are still problems such as low R&D input intensity and poor output quality.As the main body of macroeconomic regulation and control,the government,in response to the call of innovation driven,further encourages independent research and development of enterprises,has also issued a series of corporate income tax policies to support scientific and technological research and development.In order to test the implementation effect of a large number of preferential tax transfers by the government,this paper discusses the input and output of innovation activities,considers the novelty of innovation achievements,and comprehensively measures the incentive effect of preferential tax policies on innovation input intensity,total innovation output and substantial innovation output of enterprises.On this basis,enterprises are further divided into private enterprises and national enterprises.There are enterprises.It is of theoretical significance and practical value to explore the sensitivity of enterprises with different property rights to tax preference.Specifically speaking,this paper starts from the current situation of high-tech industry and tax policy,expounds the current situation of China's high-tech industry in recent years from three aspects of overall scale,innovation input and innovation output,then summarizes and sorts out the preferential policies of current corporate income tax in science and technology innovation according to two tax methods of direct preferential and indirect preferential,and puts forward to be improved Secondly,we use formula derivation and economic model to analyze the mechanism of tax incentives on innovation activities,and put forward research hypotheses.Finally,we select a total of 107 high-tech industry-related listed enterprises in 2012-2017 as sample data,and test them through empirical analysis to clarify the impact of tax incentives on high-tech industry enterprises' technological innovation Influence mechanism and incentive effect.The results show that:(1)corporate income tax preference has a significant role in promoting the innovation input of high-tech industries,and the R & D input intensity increases by 0.14% on average for every 1% reduction of the actual income tax rate;(2)corporate income tax preferential policies can significantly promote the increase of the total innovation output of high-tech industries,and every 1% reduction of the actual income tax rate will promote the total patent application The number of patents increased by 1.517%,but there was no obvious incentive effect on the output of invention patents;(3)the promotion effect of corporate income tax preferential policies on private enterprises was stronger than that on stateowned enterprises.Based on the theoretical and empirical analysis,this paper puts forward the following policy suggestions: first,optimize the way of tax preference and increase the intensity of indirect tax;second,improve the tax policy of innovation output link and consider the requirements for the novelty of output results;third,strengthen the tax preference of human capital and pay attention to the training of R&D talents;fourth,improve the innovation efficiency of state-owned enterprises and implement differentiated tax.Fifth,strengthen the follow-up management of tax policy implementation.Finally,we should make the government better allocate resources and give full play to the effectiveness of tax policies in the technological innovation of enterprises.
