- Abstract:
- Green technology innovation is the main driving force of green development. Studying regional green technology innovation efficiency is of great significance to enhance regional innovation capability and promote regional economic sustainable development. Based on the traditional DEA model for measuring the innovation efficiency of green technology, the undesired output and the “relaxation” of the factors are not considered. This paper takes the panel data of each province in 2008~2017 as a sample,evaluates the static and dynamic changes in the efficiency of green technology innovation in various regions of China in combination with the DEA-SBM model of undesired output and the global Malmquist-Luenberger index, and compares the efficiency of green technology innovation with the efficiency of pure technology innovation. Then the global spatial autocorrelation and local spatial autocorrelation are used to test the spatial correlation of green technology innovation efficiency between regions, and then the spatial econometric model is established to explore the influencing factors of green technology innovation efficiency. The research results show that the overall level of green technology innovation efficiency in various regions of China is not high, and most regions exhibit an increasing trend year by year, and the overall distribution pattern is “high in the east and low in the west”.The efficiency of pure technology innovation is better than that of green technology innovation. In most provinces, the total factor productivity of green technology innovation is increasing, and technological progress is the main factor of influence.Regional innovation efficiency has obvious spatial positive autocorrelation and spatial agglomeration effect, and the agglomeration effect is mainly reflected in the inefficient L-L quadrant and highefficiency HH quadrant.Improving technology market environment mechanism, expanding economic opening-up to the outside world, and optimizing the industrial structure have a positive role in promoting regional green technology innovation efficiency, while environmental regulation has a significant inhibitory effect on innovation efficiency development, and may be related to the crowdingout effect caused by the environmental policies in the short term.
