| In recent years,with the continuous growth of automobile sales,the scale of Chinese automobile industry is expanding constantly.The pollutants emitted from automobile exhaust aggravate the deterioration of the environment.Therefore,developing green economy,promoting industrial transformation and reducing carbon emission have become the direction for the country to guide the development of the automobile industry.In this context,new energy vehicles replace the traditional internal combustion engine with power batteries,which have the advantages of green,pollution-free,energy saving and emission reduction,and become the direction of the future reform of the automobile industry.Due to the positive externalities of new energy vehicles in technology and environment,the imbalance between private costs and benefits of enterprises will eventually lead to market failure.Government policy support and guidance is particularly important.Since 2000,China has begun to lay out new energy automobile industry and support its development through financial subsidies and tax incentives.In recent years,with the continuous implementation of policies,new energy vehicle technology continues to improve,new energy vehicles are gradually popularized at the social level,and the market scale continues to expand.However,there are still some problems,such as unbalanced development of industrial chain,lack of high-end technology,need to improve the way of fiscal subsidies and lack of targeted tax preferential policies.How to improve the implementation effect of policies in the development process of future new energy vehicles is extremely critical.Therefore,based on existing policies,this paper comprehensively analyzes the impact of fiscal subsidies and tax incentives on the performance of new energy automobile enterprises,and compares and analyzes the differences in the impact of fiscal subsidies and tax incentives on enterprise performance in all links of the industrial chain.This will have important theoretical and practical significance.This paper first introduces the research background and significance,and reviews the relevant literature at home and abroad.In the theoretical part,the theory of externality and sustainable development is discussed,and the influence mechanism of fiscal subsidies and tax incentives on enterprise performance is analyzed.Secondly,it describes the development status of new energy vehicles and their industrial chain,and analyzes the current situation of financial subsidies and preferential tax policies for new energy vehicles.Thirdly,in the empirical analysis part,grouping regression is carried out according to the upper,middle and lower reaches of the industrial chain to compare the differences of all links of the industrial chain,and further test the mediating effect of R&D input in the influencing process.Finally,the following conclusions are drawn.First,both fiscal subsidies and tax incentives have an incentive effect on enterprise performance.Second,in each link of the industrial chain,the incentive effect of fiscal subsidies and tax incentives is different.Third,R&D investment plays an intermediary role in the influence of fiscal subsidies and tax incentives on firm performance.According to the conclusion,the corresponding policy suggestions are put forward: in terms of financial subsidies,improve the subsidy methods of all links of the industrial chain and strengthen the financial subsidies at the level of research and development;In terms of tax incentives,we will formulate targeted preferential tax policies and increase preferential treatment for enterprises downstream of the industrial chain.Taking new energy automobile enterprises as the research object,this paper innovatively studies the impact of fiscal subsidies and tax incentives on the performance of enterprises in each link of the industrial chain from the perspective of the industrial chain,and compares the differences in the effects of the two policy approaches.To provide reference for the relevant fiscal and tax policy incentive theory. |
