Research On Evaluation System Of Industrial Energy Productivity Based On Parameter Method

In recent years,how to use the limited energy resources to obtain sustainable economic development has become a hot research topic in modern economics,and is promoting more and more international organizations and countries to explore the relationship between energy,economy and environment.This paper will focus on China’s industrial areas,establish the evaluation system of energy productivity,and study the performance of energy-economic-environmental system.Firstly,the stochastic frontier analysis method is used to study the industrial energy productivity of provinces and cities in China.The results show that capital and labor force are the driving factors of industrial energy productivity in China,while energy consumption and carbon emission are the inhibitory factors.During the three period,10~thh Five-Year,11th Five-Year and 12th Five-Year,the average level of China’s industrial technical efficiency is high,the actual output is close to the frontier output.What’s more,Shanghai has the highest average level of technical efficiency,followed by Beijing.Secondly,based on the stochastic frontier analysis,this paper analyzes the energy productivity of 33 sub-sectors in Shanghai’s industrial sector.The results show that capital is the main driving force of industrial energy productivity in Shanghai,while energy consumption and carbon emission are the inhibiting factors.Compared with the frontier of production,there are still 19%improvement in space for Shanghai’s industrial economic output.Electricity,heat,gas and water production and supply industries have a high degree of technical inefficiency,and their productive points seriously lag behind the optimal output.Finally,based on the Solow residual value production function,the energy productivity and carbon emission of Shanghai industry in 2020 are forecasted by regression method.The forecast results show that,according to the current development,Shanghai’s industrial energy productivity will reach 1.09 in 2020,a 37%increase compared to 2013.By 2020,carbon intensity will be 0.97 10000t per 0.1billion yuan,down 13.4%compared to 2013.
