Abstract：Green innovation,as an important part of the green development of the manufacturing industry,can provide impetus for the high-qualitydevelopment of China\'s manufacturing industry. Based on China\'s provincial panel data from 2001 to 2016,this paper uses the Super-NSBM model to calculate the green R&D efficiency and green technology achievement conversion efficiency in the green innovation process,and empirically tests the specific impact of green innovation two-stage efficiency on manufacturing development quality.The research results show that:(1)The average value of green R&D efficiency and conversion efficiency of green technology achievements in China\'s manufacturing industry from 2001 to 2016 were 0.517 and 0.737,respectively,and neither DEA was effective.The average efficiency of each stage in the eastern region was ahead of other regions.(2)Theimpact of green R&D efficiency on the quality of manufacturing development presents a "U" shaped curve relationship,and the conversion efficiency of green technological achievements can significantly improve the quality of manufacturing development.(3)In different regions,according to the inflection point in the green R&D stage,the northeast region has the advantage of preferentially entering the inflection point,while the eastern region has already crossed the inflection point during the survey period.Its green R&D efficiency has a positive effect on the quality of manufacturingdevelopment.During the transformation of green science and technology achievements,the conversion efficiency in the eastern and northeastern regions shows a positive promotion effect,while in the central region it shows a suppression effect,and the western region is not significant.
