China's economy growth speed has slowed in recent years.The 19 th major reports of the Party make it clear that China's economic development has entered in a new era and the development of economy has shifted from a high-speed growth stage to a highquality stage.And in the current competitive international environment,all countries are developing their own high-tech with the intention of grabbing the commanding heights of science and technology and the leading power in science and technology.Thus,both our country's current modern industrial construction and the severe international economic environment require our country to speed up the transformation of the current economic development and promote the high-end of China's economic industry to form a modern economic system of innovation driving economic development.Predictably,the vigorous development of China's high-tech industry will certainly have irreplaceable benign influences on the upgrading of China's economic and industrial structure,the improvement of social labor productivity and the growth of economic.Because of the high cost of R&D research and its small market share,high-tech industry need to be supposed by government.Since R&D research has the characteristics of large inverstments,high risks and spillover effects,simply rely on the market mechanism to regulate the whole society's innovative R&D research will be proned to the ‘market failure' situation.Therefore,government guides and motivates the whole society,especially to increase R&D research has become a major method of developed countries and regions to correct the market failure situation.Tax preferential policies has the characteristics of precise strength and outstanding structural features.It is widely used by government to stabilize the economy,adjust economic structure and promote the reformation of economy.Based on the basic theory of tax policy,the theory of tax policy and industrial development,combined the transmission mechanism of tax preferential policies on the development of high-tech industry,this paper analyzes and confirms the influence of tax preferential policies on promoting the development of high-tech industry from the theoretical point of view.Based on the current tax preferential policies of high-tech industry in China,this paper compares the relevant policies of high-tech industries in major developed countries,and points out the shortcomings of current policies.Through the multivariate regression model,this paper makes a regression analysis of the 2009-2017 data of 104 listed high-tech enterprises in Shanghai,and concludes that the tax preferential policies has a significant negative correlation effect on the hightech industry,and the impact of income tax is the greatest.On the basis of drawing lessons from relevant international experience,combined with China's national conditions,put forward tax preferential policies recommendations suitable for the development of China's high-tech industry and for our country to carry out economic transformation and upgrading to provide research ideas.
