Research On Innovation Efficiency Evaluation And Influencing Factors Based On Stochastic Frontier Analysis

With the rapid development of our society,economic growth,the improvement of the system and quality are closely connected to technological innovation.Technological innovation can provide new technologies,new methods and new models for our production activities.In both regional and national level,technological innovation is now in a very important strategic position.It develop extensively starting from the first technological revolution.Nowadays,China's technological innovation has also made great progress and achieved great results.Even so,the development of China's scientific and technological innovation still has plenty of difficulties.Our innovation efficiency is low and has a lack of balance which still hinders the healthy and rapid development of China's scientific and technological innovation.This paper uses the Stochastic Frontier Analysis(SFA)method to evaluate the innovation efficiency of major cities in China and then compare the innovation efficiency in the different areas.In addition to their own reasons,innovation efficiency will be affected by the external environment,economic environment and institutional environment.In order to evaluate the innovation efficiency of major cities in China and find out what factors can influence innovation efficiency,this paper collected the data of 30 major cities in China from 2006 to 2015 which contain 300 observations.This study uses the Stochastic Frontier Analysis(SFA)model to measure the innovation efficiency of the city and verify the factors that have a significant impact on innovation efficiency.We find that the efficiency of innovation is quite different in different regions.In general,China's innovation efficiency has great potential to grow in future.Besides,innovation efficiency shows a gradual upward trend over time.We also find that government,business and overseas funds will have a significant impact on innovation efficiency,and this effect is positive.Other funds and fixed assets investment have a significant negative impact on innovation efficiency.The proportion of college students in the region has a significant impact on innovation efficiency,and this effect is positive.
