Research On The Incentive Effect Of The Tax Preference On The Technology R＆D Of Photovoltaic Industry

As a strategic emerging industry,photovoltaic industry is an important industry for China to deal with the energy crisis and adjust the energy structure.Since the rise of photovoltaic industry,the Chinese government has successively issued a series of industrial policies to support the development of photovoltaic industry.The guiding role of the policy has led to the rapid expansion of the photovoltaic industry,but it has also caused problems such as over reliance on subsidies,imbalance of industrial structure,weak competitiveness and high cost of photovoltaic power generation.The reason is that the technology R＆D level of China’s photovoltaic enterprises is low,and the previous industrial policies based on financial subsidies focused on encouraging investment and construction,resulting in the situation of "emphasizing power generation over manufacturing".Therefore,this paper selects the preferential tax policy in the industrial policy to study its impact on the technology research and development of photovoltaic industry,and discusses some suggestions to improve the current preferential tax policy.The main content is divided into the following five parts.The first chapter is the introduction.Firstly,it expounds the research background of this paper,points out the importance of stimulating technology research and development of photovoltaic industry under the current policy trend and realistic conditions,then analyzes the research significance of this paper from both theoretical and practical aspects,then summarizes the main research ideas and research methods of this paper,summarizes and summarizes the relevant research of scholars at home and abroad,and finally puts forward possible innovations and deficiencies.The second chapter first defines the four concepts of photovoltaic industry,photovoltaic industry chain,tax preference and technology R＆D,and then analyzes that tax preference can promote enterprise R＆D by reducing the risk and cost of technology R＆D by using the theory of expected utility maximization.The third chapter shows the development status of China’s photovoltaic industry through industry related data,and shows the technology R＆D level of China’s photovoltaic industry through patent application.Then,through reading the policy documents,it combs and summarizes the tax preferential policies applicable to the photovoltaic industry.The fourth chapter uses the financial data of listed companies to make an empirical analysis on the incentive of tax preferential policies to photovoltaic industry technology R＆D after selecting appropriate measurement indicators.After comprehensively considering the mixed regression,fixed effect model and random effect model,the fixed effect model is selected to analyze the empirical results.The results show that both corporate income tax preference and turnover tax preference can significantly promote technology R＆D,And the incentive effect of enterprise income tax preference is better than that of turnover tax preference.The fifth chapter makes a summary on the basis of the previous empirical analysis,and puts forward some suggestions to optimize the preferential tax policies according to the types of taxes.The suggestions include: expanding the preferential policies of enterprise income tax;Improve the preferential policies of turnover tax;Adjust the preferential policies of individual income tax;Unify the land tax policy for photovoltaic power generation.
