Abstract
As a new industry, the healthy development of new energy vehicle industry is of great significance for effectively solving environmental problems and energy crises. The purpose of this study was to analyze the technological innovation process of China’s new energy vehicle enterprises and construct the evaluation index system of technology innovation efficiency of China’s new energy vehicle enterprises and SBM model-based network DEA model from the two aspects of technology research and development stage and achievement transformation stage. The overall technological innovation efficiency and staged efficiency of 16 listed new energy vehicle enterprises in China were measured and combined with the Malmquist Index Model. The technical change and efficiency change of 16 listed new energy vehicle enterprises in China, spanning from 2012 to 2018, were analyzed. The results show that the average overall efficiency of technological innovation of 16 new energy automobile companies is 0.5515, and the standard deviation is 0.2341. It reflects the low overall efficiency of technological innovation of Chinese new energy vehicle enterprises and the uneven development and the huge gap between different enterprises. From 2012 to 2018, the M index is less than 1, and the technical level change (TC) has a greater negative impact on the M index.
Highlights
With economic growth and social progress, environmental issues have raised more and more attention from people around the world
Data shows that China’s automobile production and sales in 2009 have officially surpassed the United States and become the world’s largest automobile market. It is still showing an upward trend. erefore, it is necessary to promote the development of the new energy vehicle industry with the aim of solve environmental problems and energy crisis and drive industrial growth in China as well
Is paper, taking China’s new energy vehicle companies as the research subject, is an attempt to analyze the process of technological innovation of China’s new energy vehicle companies, and construct the evaluation index system and evaluation model of technology innovation efficiency of China’s new energy vehicle enterprises. It is of great significance for allocating innovation resources, improving the technological innovation efficiency of China’s new energy vehicle enterprises, and realizing the sustainable development of China’s new energy vehicle enterprises to scientifically evaluate and measure technical innovation efficiency of Chinese new energy vehicle enterprises and find out the key factors that affect the technological innovation efficiency of China’s new energy automobile enterprises
Summary
With economic growth and social progress, environmental issues have raised more and more attention from people around the world. Data shows that China’s automobile production and sales in 2009 have officially surpassed the United States and become the world’s largest automobile market. In 1992, the research and development of electric vehicles were designated as National High-tech R&D Program (863 Program) in China It was pointed out in the Twelfth Five Year Plan on the Development of National Strategic Emerging Industries issued by the Chinese government in 2012, and new energy vehicle industry should serve as the locomotive of China’s industry in 2020, propelling growth in the entire auto industry in China. It is of great significance for allocating innovation resources, improving the technological innovation efficiency of China’s new energy vehicle enterprises, and realizing the sustainable development of China’s new energy vehicle enterprises to scientifically evaluate and measure technical innovation efficiency of Chinese new energy vehicle enterprises and find out the key factors that affect the technological innovation efficiency of China’s new energy automobile enterprises
