Abstract

Abstract:

Improving the efficiency of technological innovation in phosphorus chemical industry is of great significance to the healthy,orderly and green sustainable development of phosphorus chemical industry.With 27 listed enterprises of phospho-rous chemical industry in different provinces of China as the research objects,the evaluation system of technological innova-tion efficiency was constructed,the input-output data of enterprises in 2018 were collected,and the overall and internal analysis of technological innovation efficiency was carried out based on DEA model.The results showed that：the overall technological innovation efficiency of listed enterprises in China was 0.372,which did not meet the DEA effective standard; low pure technological efficiency or low scale efficiency was the main reason for the non DEA effective technological innovation efficiency of enterprises; close to 3/4 of listed enterprises in phosphorus chemical industry had the decline of scale return of technological innovation investment; 45% of enterprises were not DEA efficient due to redundant R&D funding and 50% of enterprises were not DEA efficient due to insufficient output.Finally,combined with the research conclusion,the countermeasures and suggestions to improve the technological innovation efficiency of phosphorus chemical industry were put forward.

Key words: phosphorus chemical industry, listed enterprises, technological innovation, efficiency, DEA model
