Abstract：For a region,the efficiency of technological innovation can reflect the strength of its scientific and technological innovation capabilities.This paper addresses the issue of incomparable frontiers in different periods and analyzes the impact of environment on technological innovation efficiency,thereby constructing an improved three-stage EBM-Windows model that considers both the external environment and the heterogeneous frontiers,hoping to more accurately assess the regional technological innovation efficiency.Based on the results of technological innovation efficiency of China's 30 provinces except Hongkong,Macao,Taiwan and Tibet from 2007 to 2016,this paper compares the efficiency of each province.The results show that after removing the effects of random disturbances and environment,the efficiency of technological innovation in most provinces has been greatly improved.By measuring the size of the influencing factors causing the efficiency change,suggestions for improving the efficiency of technological innovation in various regions have been proposed.
