The Research Of Biased Technical Progress On The Energy Intensity Of China’s Manufacturing Industry

China’s environment is facing a very grim situation,the total amount of atmospheric pollution remain high.The excessive use of energy is the reason that cause air pollution.And energy efficiency in China is low,the use of unreasonable structure,backward energy technology will seriously restrict the development of China’s economy.So the reduction of energy intensity,improving energy efficiency is imminent,especially for the manufacturing industry.Technological progress is considered to be the most important factor that affects the energy intensity,which is a famous in the theory and policy direction of our country.After reviewing the related research of technology,the manufacturing industry of our country is divided into labor-intensive,capital-intensive and technology-intensive industries,through the establishment trans logarithmic cost function of KLEM,technological progress will be divided into neutral technical progress and biased technological progress together with the consideration of the cost function.Then the effects of technological progress are divided into R&D,the introduction of technology,technological transformation and FDI.And the substitution or complementary of manufacturing industry while the intensive industry of each factor are obtained by adopting the shadow substitution elasticity.On the basis of the substitution or the complementary relationship,According to the technological progress,the change of the factor input share is calculated.Finally,according to the function,the influence of technological progress on energy intensity is derived..By using the panel data simultaneous equations model,the method of "SUR" estimation method is used to solve the equation.The regression results found in the manufacturing industry,only the energy and labor relations are complementary in the four factors of capital,labor,energy and intermediate goods,other factors are substitutes,the influence factors of technology progress are basically in favor of reducing energy.The energy intensity of R&D was the highest,1%increase in technological progress,R&D will make the manufacturing energy intensity fell by 0.294%,followed by the introduction of technology and FDI,respectively 0.109%and 0.041%,technological transformation will increase the energy intensity of 0.219%.In the manufacturing industry,the substitution of capital intensive industries and labor-intensive industries is the same with the manufacturing industry,In the technology-intensive industries,there is a complementary relationship between energy and labor,energy and intermediate goods.In the three factor-intensive industries,the direction of technological progress is basically consistent,but the degree of deviation is different,which also leads to different effects on energy intensity.R&D in capital intensive-industries,labor-intensive industries and technology-intensive industries to reduce the role of energy intensity is the largest,elasticity were 0.192,0.268,1.268,technical transformation will increase the intensity of energy.In the manufacturing industry as well as the different factor-intensive industries,biased technical progress is the main channel to reduce the energy intensity.This paper analyzes the technology progress of the four sources of R&D,technology introduction,technology transformation and FDI through the neutral technology progress and biased technical progress,the manufacturing industry and its factor intensive industry,the impact of energy intensity.On the accurate analysis of the impact of China’s manufacturing energy intensity,the development of energy efficiency related policies have a certain theoretical value and practical significance.
