| In the context of the gradual decline of China’s new energy vehicle "subsidized" policy,it is of great practical significance to further play the relay role of the "non-subsidized" policy and promote efficient innovation of auto companies.According to the two key factors of technological breakthroughs and market cultivation that restrict the enthusiasm of new energy vehicles companies at this stage,this study divides the “non-subsidized” policies into ”technical access” and“consumption support”,and research on the difference in the effect of“non-subsidized” policies on the innovation incentives of new energy vehicles companies based on the comparison of the two types of policies.Firstly,this study builds a dynamic game model based on the theory of power system branches,and studies the impact mechanism of two types of "non-subsidized" policies on the innovative strategic decisions of new energy vehicles companies.This paper selects the listed companies of Chinese new energy vehicle companies during the period 2010-2019 as the research sample,and applies the panel vector auto regressive(PVAR)model to analyze the dynamic influence on the R&D investment of enterprises of two types of "non-subsidized" policies from the two dimensions of significance and agility in different development stage,and the panel threshold model is used to study the moderating role of regional innovation atmosphere in it.The research results show that: First,the technical compensation brought about by the “technology access” policy and the market compensation brought about by the “consumption support”policy will both generate positive incentives for the innovation input and output of new energy vehicles,but they have differences in the specific effects.Technical compensation has a non-linear relationship with the innovation incentives of new energy vehicle companies.The greater the technical compensation,the faster the innovation investment of new energy car companies will increase,while the incentive effect of market compensation on the innovation investment of new energy car companies is stable linear relationship.Second,the market capacity will have a positive impact on the R&D and innovation incentives of the two types of compensation for new energy car companies,the technology improvement capabilities and production unit costs will have a negative impact,and the impact of the technology spillover rate will be related to the size of the company’s innovation capabilities.Third,the “technology access” policy has always shown a significant positive incentive effect on the R&D investment of new energy vehicle companies,and the response is more agile,and the time lag is shorter;the incentive significance of the“consumption support” policy has been weakened from strong trend,the response agility is relatively weak,and the time lag is longer.Fourth,the R&D investment incentive effect of the "technology access" policy is affected by the single threshold effect of the regional innovation atmosphere,which has a positive adjustment effect,while the "consumption support" policy is affected by the dual threshold effect of the regional innovation atmosphere,which has a negative adjustment effect.Therefore,it is necessary to give full play to the incentive advantages of the two types of non-subsidized policies at different development stages.and implement differentiated "non-subsidized" policies based on the differences in the regional innovation atmosphere,providing decision-making reference for China to formulate a differentiated new energy automobile industry innovation-driven strategy. |
