Study On Provincial Total-Factor Energy Efficiency Of China Based On Non-parametric Frontier Method

With the background of the overall world facing energy depletion and climate change, China, the world's second-largest energy-consumed country after the Unite States and the Number one carbon dioxide-emitting developing country in the world, should undertake arduous mission and responsibility for energy conservation and emission reduction. In order to relieve the energy and environmental crises to the greatest degree and adapt to the requests from own development and international community, it is necessary to carry out the energy strategy of improving energy efficiency for China's government. As a result, to study China's provincial energy efficiency and related problems scientifically, on the basis of which draw up some effective energy and environmental policies, is to have great realistic meaning for thoroughly applying the Scientific Outlook on Development, building socialist harmonious society and the realization of overall, harmonious and sustainable development of economics and the society of China.Based on non-parametric frontier method, this dissertation compares energy utilization efficiency and energy technology level under the framework of total-factor energy efficiency, on basis of which this dissertation probes the temproal and spatial evolution and impact factors of China's provincial total-factor energy efficiency. Then, we study China's energy efficiency problem under the restrains of economy, resource and evironment more systematically by introducing the environmental impacts of energy utlization in order to provide decision supports for China's each province drawing up energy conservation and emission reduction polices. The main work and innovations of this dissertation include:1. Total-factor energy efficiency model based on the joint goals of energy conservation and output growth is put forward by using DEA method and Directional Distance Fucntion (DDF). This model combines energy conservation goal and output growth goal effectively, and integrates into total-factor energy efficiency index, which makes the connotation of total-factor energy efficiency more plentiful and better conforms to our country's macroeconomic developments acutal.2. To reflect China's each province's gap between"actual energy intensity"and relative"optmal energy intensity", the conception of"enegy intensity efficiency"is put forward, which establish a bond beween"partial-factor energy efficiency"and"total-factor energy efficiency"and provides the theory basis for China's each province to draw up practical targets for enegy conservation.3. Giving plenty of consideration to the technology development gap among China's three major areas (Eastern area, Central area and Western area), this dissertation analyzes the regional differences of China's total-factor energy efficiency based on non-parametric metafrontier theory, and provides theory and practice basis for each province to draw up appropriate energy conservation and emission reduction policies.4. On the basis of total-factor energy efficiency model based on the joint goals of energy conservation and emission reduction, this dissertation uses non-parametric Luenberger indicator to investigate the temporal and spatial evolution of China's total-factor energy efficiency and decomposes the indicator into technical efficiency index and technical progress index. Then, the energy technology"innovators"which shift the frontier among China's 29 provinces are determined. Additionally, a panel data model is used to test the major impact factors of the change of China's provincial total-factor energy efficiency.5. From the standpoint of system theory, considering the negative externalities from energy utilization, this dissertation puts environmental pollution into the study framework of toal-factor energy efficiency. DEA method is used for measure China's total-factor energy efficiency of 29 provinces and three major areas including environmental effects. In order to study China's each province's technical efficiency and scale efficiency, we decompose total-factor energy efficiency into two indexes of pure techncial efficiency and scale efficiency. Consequently, four kinds of models of China's provincial energy efficiency were put forward and Tobit model was used to investigate the formulation reasons for the regional difference of China's total-factor energy efficiency.6. Environmental DEA technology and Directional Distance Function are used to build up the model of China's provincial environmental efficiency of energy utilization. In the course of empricial study,"environmental regulation"is introduced to the dissertation's study system, on the basis of which China's all provinces'losses of efficiency and regulation costs from environmental regulation are measured.
