| Since the reform and opening,China's economy has made rapid development.Meantime,it has brought serious problems in environmental and energy consumption.Recently,China's air has been severely affected,smog has become increasingly serious.The reason for this phenomenon is the excessive emission of carbon dioxide from the rapid development of industrial enterprises.The process of carbon reduction by enterprises is imminent.In China,the core of industrial carbon emission reduction is industrial technological progress.Which is the fundamental measures for achieving carbon emission reduction.Therefore,deeply study of the carbon emission reduction effects of technological progress in China's industrial sector has important practical significance for proposing effective strategies to achieve low carbon targets in China's industrial sector.This paper uses the STIRPAT(Stochastic Impacts by Regression on Population,Affluence,and Technology)model to measure the carbon emission intensity of 32 se-ctors in China's industrial sector from 2000 to 2016.It focuses on analyzing different paths of technological progress,R&D spending,human capital,foreign direct inves-tment,effective patented inventions,and technology transformation expenditure on carbon intensity.Finally,a panel quantile regression model was used to examine the differential impact of various technological advances on the industrial sectors with different levels of carbon emissions.The main conclusions of this paper are as follo-ws:(1)From 2000 to 2016,the average level of carbon emission intensity in China's industrial industry was 2.74 million tons of standard coal per million,and the carbon emission intensity of all sectors showed a declining trend as a whole.During the sample period,the carbon intensity of the industrial sector presented two phases:In the first phase,the intensity of carbon emission intensity fell drastically from 2000 to 2008,from 5.31 to 2.02,with an average annual growth rate of-11.38%.In the second phase,in 2008-2016,the carbon emission intensity decreased slowly,from 2.02 to 1.43,with a growth rate of-4.23%,and the decline rate was gradually slow.In terms of subdivision industries,the carbon emission intensity of the electricity and heat production and supply industry(H30)is the highest(129,500 tons of standard coal per million);the carbon emission intensity of communications equipment,computers,and other electronic manufacturing industries(H29)The lowest(0.05 tons of standard coal per 100 million yuan),the difference in carbon emission intensity between the two industries is huge,there is a huge difference in the carbon emission intensity between industries.(2)Through the analysis of the regression model,it was found that various approaches to technological progress have a significant impact on the overall carbon intensity of China's industrial sector.In technological innovation,there is a negative relationship between carbon intensity and RD.By increasing R&D expenditures,the carbon intensity of the industrial sector can be reduced;human capital and carbon emission intensity are negatively correlated and the industrial sector is improved.The number of scientific research is beneficial to the industry to reduce carbon emission intensity.For technology diffusion,foreign direct investment and effective patent authorization also have a negative correlation with carbon intensity.Increasing foreign investment and effective patent authorization can reduce the carbon intensity of the industry.Finally,in the technology transfer and introduction,the coefficient of expenditures for technology transformation and carbon emission intensity is positive,which indicates that the technology transfer and introduction of the industrial sector in China's will increase the carbon emission intensity of the industry.Therefore,China's industrial sector should increase investment in R&D expenditures,human capital,foreign direct investment,and effective patent grants,and appropriately reduce investment in technology transformation,thereby reducing the carbon intensity of China's industrial sector.(3)For industries with extremely low carbon intensity,increasing the expenditure on technological transformation is not conducive to carbon emission reduction,it can increase R&D expenditure,human capital,foreign direct investment and effective patent authorization to reduce carbon intensity.For the lower carbon emission industries,it should increase the amount of foreign direct investment and human capital investment,appropriately increase the investment in research and development expenditure and effective patent authorization and reduce the expenditure on technological transformation.For industries with moderate carbon emission intensity in industry,Foreign direct investment has the most obviously effect on carbon emission reduction,followed by R&D expenditure and effective patent authorization and human capital.It should increase the investment of foreign direct investment,increase the R&D expenditure and the effective patent authorization,and reduce as much as possible on the investment in technical transformation expenditures.For industries with higher carbon emission intensity,we should pay more attention to the investment of foreign direct investment,and at the same time increase the investment of human capital,R&D expenditure and effective patent authorization.The technical transformation funds have a very high carbon emission intensity.Strong negative impact,and significant impact,to significantly reduce the expenditure of technical renovation funds;for industries with extremely high carbon emission intensity,the cost of technological transformation has a significant increase in carbon emission intensity,and technology should be reduced as much as possible.Expenditure on renovation funds,foreign direct investment is largely.The innovation of this paper is that the previous researches on carbon emissions are mostly from the perspective of sub-regional or overall research.People pay little attention to the impact of technological progress on carbon emission reduction from allangles of the industrial sector.Therefore,this paper studies from this perspective and puts forward corresponding opinions on carbon emission reduction.Another innovation of this paper is using the panel quantile regression model to verify the relevant indicators.Combining the quantile regression with the panel data model to analyze the relationship between the paths of technological advancement and the intensity of carbon emissions,can better analyze carbon on the basis of controlling individual heterogenity in which the emission intensity is affected by technological progress at different quantiles of different conditional distributions. |
