| Driven by national policies,China’s economy has developed rapidly and the construction of a modern economic system has been constantly improved.However,these achievements are built on the basis of sacrificing excessive energy and polluting the environment.In order to maintain long-term economic development,China needs to change the extensive economic growth model and complete the green transformation of the industry.As a typical representative of heavy industry,the impact of energy intensive industry on energy consumption and carbon dioxide emissions should not be underestimated.Price mechanism is an important way for the market to optimize the allocation of resources and promote the transformation of enterprises.However,due to the policy environment and other factors,the price is distorted and cannot play a full role.Based on the difference of energy prices between China and the United States,this thesis constructs a calculation model of energy price distortion to calculate the price distortion of energy products(coal,oil and electricity)and the overall distortion of energy prices from 2003 to 2019.The energy price distortion is brought into the stochastic frontier model of trans-log production function as an inefficiency term,and the energy efficiency and carbon emission efficiency values are calculated to study the impact of energy price distortion on energy efficiency and carbon emission efficiency of energy-intensive industries.The regional heterogeneity characteristics of energy efficiency and carbon emission efficiency in energy-intensive industries are studied from the perspectives of cities and urban agglomerations.The results show that: the overall energy prices show a negative distortion in the sample period,with oil prices being the most distorted(-0.393),followed by coal(-0.349)and electricity(-0.172).Energy price distortion has been greatly improved,rising from-0.502 to-0.115.The coal price distortion has the greatest mitigation,followed by the oil price distortion,and the electricity price distortion shows an inverted U-shaped trend,with less mitigation.Distortion of energy prices has an inhibitory effect on energy efficiency in energy-intensive industries.For every 1% increase in energy price distortion,energy efficiency decreases by about 0.342%.The introduction of foreign direct investment,the improvement of infrastructure and technological progress are conducive to the improvement of energy efficiency,while environmental regulation has a negative effect on energy efficiency.There is regional heterogeneity in energy efficiency.The energy efficiency of eastern coastal cities is generally higher than that of western inland cities.The urban agglomeration in the Pearl River Delta and the Yangtze River Delta has a high degree of integration and high energy efficiency.On the contrary,the urban agglomeration in the Beijing-Tianjin-Hebei region and the middle reaches of the Yangtze River has a low degree of integration and a low level of energy utilization.Energy price distortion has a negative impact on the carbon emission efficiency of energy-intensive industries.For every 1% increase in energy price distortion,carbon emission efficiency decreases by about 0.021%.The improvement of infrastructure and the increase of R&D investment can promote the carbon emission efficiency,while the improvement of urbanization level can inhibit the carbon emission efficiency.The regional heterogeneity of carbon emission efficiency is high in the east and low in the west.Carbon efficiency in Beijing-Tianjin-Hebei urban agglomeration is the highest(0.904),followed by Pearl River Delta urban agglomeration(0.880),Yangtze River Delta urban agglomeration(0.862)and urban agglomeration in the middle reaches of the Yangtze River(0.841).The effective implementation of policies promotes the improvement of carbon emission efficiency of energy-intensive industries in the Beijing-Tianjin-Hebei urban agglomeration.However,the urban agglomeration in the middle reaches of the Yangtze River has problems of low strategic synergy and lack of synergy,resulting in a slow increase in carbon emission efficiency.Finally,based on the empirical results,the thesis puts forward policy suggestions on green transformation of energy-consuming industries.This thesis includes 13 figures,15 tables and 130 references. |
