Research on the evaluation of comprehensive efficiency of technological innovation and eco-environment in China

To investigate the contribution of technology innovation to eco-environment, this paper sets up a comprehensive efficiency evaluation index system of technology innovation and eco-environment. A relational two-stage data envelopment analysis model with output orientation has been built to evaluate the comprehensive efficiency of technology innovation and eco-environment of 28 provinces of China for 2015. The efficiencies of two-sub-stages, technology innovation efficiency, and eco-environment efficiency have been evaluated and analyzed. The result shows that: first, the average of comprehensive efficiency of technology innovation and eco-environment is 0.1535, which indicates a low level. Second, the results of sub-stages show that the average value of technology innovation efficiency is higher than that of eco-environment efficiency. Third, the comprehensive efficiencies of technology innovation and eco-environment of 28 provinces are mostly influenced by their eco-environment efficiencies. Based on these results, corresponding countermeasures are suggested to improve the comprehensive efficiency of technology innovation and eco-environment of China. (C) 2020 Elsevier Ltd.

Automated summary

This study establishes a comprehensive efficiency evaluation index system and a data envelopment analysis model to assess the technology innovation and eco-environment efficiency of 28 provinces in China in 2015. The results indicate a low level of comprehensive efficiency, with technology innovation efficiency having a higher average value than eco-environment efficiency. Most provinces' comprehensive efficiency is mainly influenced by their eco-environment efficiencies. Based on these findings, recommendations for improving China's technology innovation and eco-environment comprehensive efficiency are proposed.
