Research On The Influence Of Science And Technology Innovation On Green Economy Efficiency In OECD Countries

In recent years,the sustainable development of economy and society has been increasingly restricted by the exhaustion of resources and the deterioration of the environment.To promote the coordinated development of economy,society and resources and environment has increasingly become a key issue for realizing sustainable development,and has also become a hot issue of universal concern of the international community.At present,global sustainable development has entered a new stage in which green is the main driving force.The development of green economy has become an international consensus among countries around the world to address resource and environmental challenges and achieve sustainable economic and social development.With the advent of the era of knowledge economy,major countries in the world have successively taken science and technology innovation as one of their core national strategies,trying to seize the commanding heights in the new round of global economic transformation through science and technology innovation and promote sustained and healthy economic development.Science and technology innovation is an important part of innovation geography research,and the main driving force for coordinating the contradiction between economic development and resources and environment,and promoting regional greening.Relying on science and technology innovation to drive the development of green economy has become an inevitable choice for sustainable development under the new normal of global economy.Similarly,with the development of China’s economy into the new normal,growth conditions,factors of production,supply and demand structure took place many changes,such as on investment,inputs of extensive pattern of economic development is unsustainable and developing green economy has become an inevitable choice for China to cope with climate change,ease the contradiction between economic development and resource and environmental constraints,and promote high-quality economic development.Based on the theories of regional sustainable development,the paper evaluates the level of science and technology innovation and green economy efficiency of OECD countries by using the entropy method and the Super-efficient SBM model based on undesired output,this paper analyzes the time-space evolution characteristics of both by means of Gini Coefficient and kernel density estimation,and probes deeply into the effect of science and technology innovation on Green economy efficiency by constructing panel regression model.Based on the results of empirical analysis,the paper draws lessons from the typical experience of representative countries,and puts forward some policy suggestions to promote the green economy development driven by science and technology innovation.The main conclusions of the study are as follows:(1)The level of science and technology innovation of all OECD countries and countries with different economic levels showed a trend of fluctuation and increase during the study period.The level of science and technology innovation showed a trend of gradual decline from countries with high economic level to countries with medium and low economic level.During the research period,the spatial pattern of the level of science and technology innovation changed significantly.The high-level area was mainly developed countries in northern Europe,Western Europe,North America,Oceania and east Asia,while the low-level area was mainly underdeveloped countries in central and eastern Europe,southern Europe and Latin America.The degree of centralization of lorentz curve decreases obviously,indicating that the level of science and technology innovation tends to balance.The gini coefficient fluctuated from 0.516 to 0.354,and the trend of regional difference was significantly weakened.Nuclear density analysis shows that the overall level of science and technology innovation has improved,and the trend of multi-polarization has begun to emerge.The proportion of countries in the upper middle level has significantly increased.(2)The green economy efficiency of all OECD countries showed an obvious trend of fluctuation during the study period,but there was no significant change at the beginning and end of the year.The green economy efficiency of countries with medium and high economic levels showed a trend of fluctuation and increase,while that of countries with low economic levels showed a trend of fluctuation and decline.During the study period,the spatial pattern of green economy efficiency changed relatively little.The high-level areas were mainly located in northern Europe,Western Europe and Oceania,while the low-level areas were mainly located in the Americas,central and eastern Europe and east Asia.The lorenz curve shows no significant change,indicating that the efficiency of green economy is still relatively concentrated.The gini coefficient fluctuated from 0.514 to 0.483,and the regional differences in the efficiency of green economy among countries weakened.The changing trend of kernel density curve shows that the efficiency of green economy has been improved,and countries with strong polarization trend and lower middle level still account for a large proportion.(3)The effect of science and technology innovation on green economy efficiency of different research units presents obvious heterogeneity.From the perspective of OECD countries,science and technology innovation promotes the development of green economy by driving resource utilization efficiency improvement,industrial structure optimization,human capital optimization and pollution treatment and remediation.According to the grouping of economic development level,science and technology innovation in countries with high economic level has a negative impact on green economy efficiency,while science and technology innovation in countries with medium and low economic level has a positive impact on green economy efficiency.According to the grouping of science and technology innovation level,the effect of science and technology innovation on green economy efficiency is basically the same as the grouping result based on economic development level.According to the grouping of input and output types of science and technology innovation,countries with a high level of input and output coordination and countries with a leading output are relatively conducive to giving play to the promoting role of science and technology innovation in promoting the efficiency of green economy.(4)Although China’s strength in science and technology innovation has continued to improve and it has entered the ranks of scientific and technological powers,it still has a long way to go before it becomes one of the world’s leading scientific and technological powers,there are still some problems in science and technology innovation,such as the overall strength to be improved,the policy support to be strengthened,the construction of science and technology innovation system to be improved,and the transformation rate of science ang technology innovation achievements to be improved.China should promote the sustained and healthy development of the green economy driven by science and technology innovation in terms of implementing the strategy of innovation-driven development,Speeding up the process of building a country with strong science and technology achievement,increasing investment in research and development of green science and technology,strengthening the policy guarantee of green science and technology,constructing a green science and technology innovation system,improving the cooperation mechanism for science and technology innovation and optimizing the evaluation mechanism for science and technology achievements.This paper explores the spatial and temporal evolution of science and technology innovation and green economy efficiency in OECD countries and the effect of Science and technology innovation on Green economy efficiency,has the following innovation points: Firstly,from the perspective of science and technology innovation,it explores its influence effect and action path on the efficiency of green economy,enriches and perfects the influence mechanism of green economy efficiency;Second,taking OECD countries as the research object,the paper analyzes the situation of their science and technology innovation and green economy development from a global perspective,to a certain extent,it provides some reference value for related research on macro scale.
