Measurement And Influencing Factors Of Regional Carbon Productivity

Since the reform and openness,Economy of China has grown at a rapid rate,and lives level have undergone enormous changes.However,due to the past extensive economic development that brought huge carbon dioxide emissions,the Carbon emission reduction issues has become a focus of the whole world.Faced with the pressures from the world,China took the goal with positive attitude that achieving 40%-45% reduction in carbon emissions by 2020 at the climate summit held in Copenhagen.However,China is being a period of economic transition currently.To realize this emission reduction target,it will certainly pay a huge economic price.Based on the background,developing “low-carbon economy” and raising the carbon productivity level are the most effective ways to achieve energy conservation and emission reduction and maintain rapid economic growth.As the three major growth poles of the Chinese economy,the three major economic circles,have superior geographical location,relatively high level economic development and play a guiding role in the development of other regions.Therefore,we must actively explore the development path of energy conservation and emission reduction,and provide reference for the development of low-carbon economy in other regions.Based on the relevant theories,this paper uses the panel data from 2000 to 2015 to calculate and comparative analyze the carbon productivity of the three major economic circle.We use the convergence analysis of to analyze the convergence of carbon productivity in the three major economic circles.Finally,empirical studied the influencing factors of carbon productivity through a panel data model,and measured the degree of influence of each factor on carbon productivity.Empirical study found that the levels of carbon productivity in the three regions of the Pearl River Delta,the Yangtze River Delta,and the Beijing-Tianjin-Hebei Region decrease in turn,and the differences in carbon productivity between and within regions are relatively large;there is no absolute convergence in the Beijing-Tianjin-Hebei region's carbon productivity.There is convergence in the carbon productivity of the Pearl River Delta,the Yangtze River Delta,and there is a convergence of condition in the carbon productivity of the three major economic circles.Energy intensity and population scale inhibit the carbon productivity of the three economic circles,and the per capita output inhibits the Beijing-TianjinHebei region and the Yangtze River Delta region.The inhibition of carbon productivity has no obvious effect on the Pearl River Delta region.The increase in the proportion of the secondary industry has a positive effect on the carbon productivity of the Beijing-Tianjin-Hebei region,while it has a deterrent effect on the other two regions.The level of foreign trade has a positive effect on in Beijing-Tianjin-Hebei region's carbon productivity,it plays an inhibitory role in the Yangtze River Delta Region,and it does not play a significant role in the Pearl River Delta region.Technological progress has promoted the improvement of carbon productivity in the Beijing-Tianjin-Hebei region and the Pearl River Delta Region,but the effect is not significant to Yangtze River Delta Region.Finally,according to the above research results,this paper gives the following policy recommendations for the improvement of carbon productivity in the three major economic circles.Promoting technological progress,advancing research and development of clean technologies,accelerating the optimization and transformation of industrial structure,developing low-carbon industries,and optimizing foreign trade structure,expanding the level of foreign trade;improving the carbon trading system and promoting low-carbon legislation.
