Analysis Of The Impact Of Technology Advance On Carbon Dioxide Emissions

Environmental issues have become the most serious challenge faced by the Chinese society in the 21st century,and is also one of the most sensitive political and social problems today.With China's rapid economic development,its profound contradictions against resources and environment is increasingly acute.The environmental carrying capacity has reached or come near to the upper limit,thus becoming one of the most severe threats during China's economic development under New Norm.Exploring the impact of technological progress on carbon emission is of great theoretical and practical significance,especially in terms of carrying out the green development concept and building up a beautiful China which is resource-saving and environment-friendly.This paper is divided into four parts.The first part contains systematical analysis and existing research results,which lay the foundation for the follow-up study.In the second part,this paper discusses the impact mechanism of technological progress on carbon emission based on the definition of technological progress and carbon emission,providing theoretical support for the later research.In the third part,the DEA-Malmquist index method is used to measure the total factor productivity of each province as the index of technological progress.Meanwhile,the carbon dioxide emissions of each province are measured and calculated,generating statistical analysis on the technological progress level and carbon emission status of each province.The fourth part is the application of dynamic panel model of technological progress on carbon emission constructed based on STIRPAT model,supported by the provincial panel data during 2002-2014.The generalized moment estimation method is used to estimate the model,and the effects of technological progress on carbon emission are compared by stage and region.Finally,the paper puts forward relevant policy suggestions to reduce carbon dioxide emissions from three aspects:encouraging enterprises to develop low-carbon technologies,promoting industrial upgrading to reduce carbon emissions,and gradually establishing and improving the market mechanism of carbon emission.This paper argues that technological progress can improve the utilization efficiency of traditional fossil energy,promote the upgrading of industrial structure,and reduce unit energy consumption and carbon dioxide emission per GDP.Lowing carbon emission is a constantly-adjusting process;technological progress can directly reduce carbon emission and has a significant lag effect.After 2009,the influence of technological progress on carbon reduction is distinct.The technological progress's effect on the inhibition of carbon emission has great regional discrepancy in China,which is better in the eastern region than in the central and western regions.The innovations of this paper are as follows:First,based on the generalized moment estimation method,it constructs the econometric model of the impact of technological progress on carbon emission in different stages.Also,the three sub samples of eastern,central and western regions are constructed to explore the regional differences of technological progress's impact on carbon emission,which makes the study more in-depth and specific,and suggestions more targeted.
