Research On The Impact Of Green Technology Innovation On Regional High-Quality Economic Development

At present,China’s economy has shifted from the stage of high-speed growth to high-quality development,how to coordinate the relationship between economic development and environmental protection is crucial to continuously promote high-quality economic development.Green technology innovation integrates green development concept and innovation driven strategy,which is of great significance to promote the synergistic interaction between ecological civilization construction and green economic development,accelerate the transformation of economic development mode to green and low-carbon,realize the high-quality development of regional economy.On the one hand,combined with the guiding ideology and connotation of high-quality economic development,the comprehensive evaluation index system of high-quality economic development is constructed from five dimensions: optimization of economic development structure,change of economic development dynamics,improvement of economic development efficiency,sharing of economic development achievements,improvement of ecological resources and environment,and the entropy TOPSIS method is used to measure the level of regional high-quality economic development.On the other hand,on account of green innovation perspective,the specific impact effect of green technology innovation on high-quality economic development is explored.The static panel model,dynamic panel model and spatial Durbin model are established to empirically investigate the overall promotion effect,nonlinear impact,and spatial spillover effect of green technology innovation on regional high-quality economic development.The research results show that:(1)China’s high-quality economic development level shows a steady growth trend,but there is obvious regional imbalance,forming a development trend of "high in the east,flat in the middle and low in the west".The catching-up effect of the central and western regions gradually emerges,and there are strong spatial dependence and spatial agglomeration characteristics of each region’s high-quality economic development.(2)Green technology innovation significantly promotes regional high-quality economic development,and it has a "U-shaped" non-linear influence of first inhibiting and then promoting.The high-quality economic development shows obvious pathdependent characteristics and cumulative effects.Green technology innovation influences high-quality economic development by improving resource allocation efficiency,promoting energy saving and emission reduction,and expanding regional market demand.(3)From an overall perspective,there is a significant positive spatial autocorrelation among regions in terms of high-quality economic development,and green technology innovation shows a significant positive spatial spillover effect on high-quality economic development.Green technology innovation in the eastern regions and central regions has a positive spatial spillover effect,while the negative spatial spillover effect in the western region is more significant.To this end,the following countermeasures are proposed:Continuously improve the level of green technology innovation and make the most of its important role in production efficiency improvement,ecological civilization construction and high-quality economic development.Mobilize the motivation and enthusiasm of green technology innovation subjects,effectively stimulate resource allocation effect,energy-saving and emission reduction effect,and market demand effect of green technology innovation.Improve the innovation cooperation and technology sharing mechanism between regions,enhance the overall regional high-quality economic development level through the spatial spillover effect of green technology innovation.
