| The formulation and implementation of science and technology innovation policy is not only an important means for the government to promote the development of science and technology,but also one of the main contents of science and technology environment innovation.High-end technological competition is gradually evolving into a competition of innovation incentive policies.The government has continuously introduced supporting incentive policies for various fields.Strategic emerging industries,as the areas with the highest concentration of innovation activities,are the key to strengthen competitiveness.Whether fiscal and tax incentive policies can really promote the innovation of strategic emerging industries,and how to give better play to the innovation incentive effect of fiscal and tax policies,to improve the core competitiveness of Chinese industries have become urgent issues to be solved.This paper firstly sorts out relevant theories in the field of fiscal and tax incentive policies and summarizes the influence mechanism on innovation.Secondly,this paper combs Chinese current government subsidy and tax preferential policies from the perspective of reality,analyzes the transformation of innovation achievements of fiscal and tax incentive policies from the perspectives of innovation input and output,and finds that with the increasing implementation intensity of fiscal and tax policies,innovation input and achievements increase.Then,taking listed companies of new energy industry from 2015 to 2021 as the research object,this paper analyzes the implementation effects and action paths of tax preferential policies and government subsidies by using fixed effects and mediating effects models.Finally,this paper also analyzes the heterogeneity of this incentive effect from the perspectives of property rights and regions.Both policies stimulate technological innovation of enterprises,and the incentive effect of government subsidies is more significant.Fiscal and tax incentive policies help alleviate the financing constraints of new energy enterprises.Financing constraints partially mediate the relationship between fiscal and tax incentive policies and innovation performance of new energy enterprises,that is fiscal and tax incentives improve innovation performance of new energy enterprises by alleviating financing constraints.Financing constraints will be different due to property right heterogeneity and regional heterogeneity,so fiscal and tax incentive policies have a greater role in promoting innovation performance in non-state-owned enterprises and enterprises located in the eastern region.Finally,based on the important conclusions found in this paper,corresponding policy suggestions are put forward for better use of fiscal and tax incentive policies to improve the innovation performance of new energy enterprises.Fiscal and tax incentive policies have a positive impact on the innovation performance of new energy enterprises,which should be strengthened to improve the fiscal and tax incentive policies.Formulate differentiated fiscal and tax incentive policies according to local conditions.When formulating innovation policies,the central government will increase support to the central and western regions,focus on the transfer of innovative personnel to the central and western areas,the establishment of R&D infrastructure and technology sharing platform and increase policy support for the technological innovation of non-state-owned new energy enterprises.Establish a financial system to support technological innovation of new energy enterprises in various ways,and expand external financing channels for new energy enterprises.Enrich the forms of fiscal and tax incentives.We will continue to promote and improve preferential policies for promoting enterprise innovation.According to the development situation and technological innovation level of different new energy enterprises,precise support is provided,and more financial support is given to enterprises with lower technological innovation output.Enterprises should also improve their management of the accounting level,set up research and development activities of special accounting books,policy details and specific accounting methods should be timely communication with the local tax authorities. |
