Research On The Impact Of Financial Development On Green Technology Innovation Efficiency From The Perspective Of Spatial Spillover

The report of the 20 th National Congress of the Communist Party of China pointed out that we should "accelerate the implementation of the innovation driven development strategy,enhance the ability of independent innovation,and promote high-quality economic development".Innovation is the first driving force for economic development and has played an important role in China’s economic development.However,for a long time,China’s development model of "high pollution","high emissions" and "low energy efficiency" has seriously hindered the improvement of innovation efficiency.At the same time,this extensive development model has caused serious environmental pollution and waste of resources,which has restricted the sustainable development of China’s economy.Therefore,it is of great theoretical and practical significance to study how to improve the efficiency of green technology innovation.Financial development is one of the important factors that affect the efficiency of green technology innovation.How to play the role of finance in promoting the efficiency of green technology innovation is worth discussing.In addition,with the continuous close connection between various regions,the role played by spatial factors cannot be ignored when discussing the relationship between financial development and green technology innovation efficiency.First of all,this paper takes the impact of financial development on green technology innovation efficiency from the perspective of spatial spillover as the research theme,sorts out related content such as financial development,green technology innovation efficiency,and spatial spillover,and analyzes in detail the impact of financial development on green technology innovation efficiency and its impact.Mechanism basis of spatial spillover effects.Secondly,select the panel data of 30 provincial-level administrative regions in my country from 2006 to 2020,and use the super-efficiency SBM model with negative output to measure the green technology innovation efficiency of 30 provincial-level administrative regions in my country.Thirdly,using panel data fixed effect model,spatial autocorrelation model,spatial error model and spatial Durbin model to empirically test the impact of financial development on green technology innovation efficiency and its spatial spillover effects.Then,according to the results of theoretical analysis and empirical testing,this paper puts forward relevant policy recommendations to promote the efficiency of green technology innovation from the perspective of financial development.
