Research on the Impact of National Unified Large Market Construction on the Innovation Efficiency of the New Energy Industry Chain
Improving the innovation efficiency of the new energy industry chain is an important hand to seize the dominance of China's new energy industry in global development and shape the competitive advantage of a great power.Based on the panel data of 77 listed companies in China's new energy industry chain from 2017-2022,the innovation efficiency of each link of the industry chain was measured by a four-stage DEA model,and the impact of national unified large market construction on the innovation efficiency of the new energy industry chain was analyzed by using a threshold regression model.After adjusting the stochastic frontier analysis method,it is found that national unified large market construction has a non-linear threshold effect on the innovation efficiency of the new energy industry chain,and the innovation efficiency of each link of the industry chain as a whole shows the phenomenon of"inverted".Through the heterogeneity analysis,it is found that national unified large market construction has a positive correlation with the innovation efficiency of state-owned enterprises in the new energy industry chain.Therefore,it is recommended to reduce the innovation risks in the downstream application of the industry chain,improve the profitability at the end of the industry chain,promote industrial agglomeration,and strengthen international cooperation,thereby improving the innovation efficiency of the new energy industry chain.
