Evaluation of Technological Innovation Efficiency of Chinese Industrial Enterprises above Scale
Based on the review of the literature on innovation efficiency,we construct two dimensions of innovation efficiency:innovation input and innovation output,and evaluate the innovation efficiency by using the DEA cross-efficiency with the industrial enterprises above scale in China from 2013 to 2022 as the research object,and the results show that the innovation efficiency of Chinese industrial enterprises above scale in 2013-2022 has been increasing year by year.The results show that from 2013 to 2022,the innovation efficiency of Chinese above-scale industrial enterprises as a whole shows an increasing trend year by year.The results show that the innovation efficiency of industrial enterprises above scale in China is increasing year by year from 2013 to 2022.The innovation efficiency is different in different regions,especially in the western provinces,which needs to be further improved.
