The competitiveness of new energy automobile industry depends on technological innovation,and how to improve the efficiency of technological innovation of China's new energy vehicle enterprises is the focus of promoting the development of China's automobile industry.Based on the innovation value chain theory,this paper divides the innovation process of enterprises into two stages,which are technological innovation and achievement transformation.It selects sixteen new energy vehicle enterprises as research object,and the SBM network model and Malmquist index model are used to measure the innovation efficiency of vehicle enterprises from static and dynamic perspectives.The results show that the efficiency of the technological innovation stage in new energy automobile enterprises is lower than that of the achievement transformation stage,but the efficiency of firms'technological innovation has generally continued to improve.Therefore,the two key points to enhance the efficiency of technological innovation in automobile enterprises are to focus on the efficiency of the technological innovation stage and to promote the practical application of the invention results.
