Research On Innovation Efficiency Evaluation Of Listed Companies In Strategic New Industries In China

With the promptly development of today’s scientific and technological society,innovation of science and technology as to improve national innovation ability and international status of important strategic innovation of society there is an indispensable role in economic growth,and the strategic emerging industry as a new kind of new power to facilitate the progress of social economy,in the process of awakening again for the world economy plays a more and more important role.Like other countries in the world in strategic transition,China has positioned strategic emerging industries as the new orientation of future industrial development and innovation of science and technology,and facilitated strategic projects for the development of newly developed industries Strategic emerging industries are mainly based on China’s current development needs,selected and developed with international thinking,and play an important leading role in social development.In this paper,six hundred twenty four listed companies in seven strategic emerging industries from 2015 to 2019 are selected,and the three-stage DEA model and DEA-Malmquist index are used to measure the innovation efficiency of these enterprises through dynamic and static analysis.And It first introduces the research background and research status at domestic and overseas,and then analyzes the concept of strategic emerging industry scope and the affecting factors of innovation workpiece ratio.By building seven big strategic new industry innovation efficiency evaluation index system and model selection of listed companies,listed companies on China’s strategic emerging industry innovation efficiency evaluation of empirical research,by comparing the phase three phase innovation efficiency results and Malmquist index,summed up the overall strategic emerging industry innovation efficiency is low,there is a big room to improve.From 2015 to 2019,the total factor productivity index of China’s strategic emerging industries is less than 1.After two-stage SFA model regression,after removing the influence of random interference and external environmental factors on input variables,Technological efficiency and technological progress index gradually converge.Based on the empirical consequence,this paper brings forward some proposals on how to perfect innovation efficiency in seven strategic emerging industries in a view of both macro and micro.At present,the innovative development of China’s strategic emerging industries still needs to be greatly enhanced,and the country should pay attention to some innovative research and development methods to promote core technologies in key areas.
