| In recent years,global warming,ecological environment damage,air pollution and other phenomena have become a great threat to the sustainable development of the global economy.After a long period of scientific exploration,governments and relevant institutions have started to formulate policies related to appropriate carbon emission reduction activities.Only by better improving the efficiency of carbon emission can global warming and energy waste be effectively reduced.At the same time,technological innovation,as one of the key ways to realize the above process,has also attracted much attention.In the context of "double carbon" and great progress in science and technology,China needs to rely on scientific and technological innovation to improve carbon emission efficiency.The improvement of green development level and the need for the management of ecological civilization can in turn promote industries and enterprises to upgrade technology,and force the improvement of scientific and technological innovation level.The two complement each other and cannot be achieved without one.After sorting out and calculating the relevant data,this paper obtains the relevant panel data of technological innovation and carbon emission efficiency.On this basis,PVAR model is constructed to analyze the dynamic influence mechanism of the two,and the conclusion that the two influence and promote each other is drawn,which provides theoretical support for the analysis of the coupling degree of the two.Then,this paper describes the Moran index and LISA distribution map of Chinese provinces and cities by Arc GIS,Geo Da and other spatial visualization tools,and well explains the spatial distribution pattern of the coupling degree between Chinese carbon emission efficiency and scientific and technological innovation capability.Dagum Gini coefficient and its decomposition method were introduced to explore the spatial differences and sources of the coupling and coordinated development of carbon emission efficiency and technological innovation.Through the above research,the following main conclusions are drawn:(1)there is a positive promoting effect between the two variables in the short term;In the long run,it also has a relatively obvious interactive relationship and coordinated development,among which the influence of scientific and technological innovation level on carbon emission efficiency presents an inverted "U" shape,and the improvement of carbon emission efficiency can force the improvement of scientific and technological innovation level in the short term.(2)Combined with the spatial distribution maps of each region in 2010,2013,2016 and 2019,it can be seen that there is a significant Matthew effect on the whole,that is,the coupling degree shows the characteristics of "more is always more,less is always less".(3)The increasing path of coupling degree between carbon emission efficiency and scientific and technological innovation level.Regions with high development and high coordination,such as Beijing,Shanghai,Guangdong and Jiangsu,need to maintain an upward trend,achieve both carbon emission efficiency and scientific and technological innovation level,learn from international advanced technology and industrial structure,and build a continuously improved green and low-carbon innovation development system.We should identify the entry point and foothold of systems and policies,start from the underlying structure and technology,and realize the coupling and coordinated development of carbon emission efficiency and scientific and technological innovation level step by step.Based on the study of the dynamic response mechanism and coupling relationship between the two,this paper aims to provide scientific reference for realizing the harmonious unity of carbon emission efficiency and technological innovation development,and provide suggestions for realizing the overall development of ecological environment and technological innovation. |
