A Research On The Upgrading Of Industry Structure Optimization Under The Energy Constraint

Energy has been the important material basis for human's subsistence and production Since the Economic Reform and Opening Up, China has maintained high-speed economic growth by heavy consumption of energy, which, however, causes the economic growth more and more closer to the boundary of energy constraint. If the traditional upgrading pattern of industry structure optimization can not be well transformed, it will inevitably exacerbate the energy insufficiency and environment destruction, and will ultimately affects the sustainability of economic development. In this regard,, this thesis, based on China's concrete situation, has analyzed the mechanism of industry structure upgrade and optimization under the energy constraint; studied the energy structure optimizing and upgrading within the industry and the enengy efficiency and industry structure optimization and upgrade across industries; and finally from the perspective of industry connection with case study, it has analyzed how enterprises can promote the industry structure optimizing and upgrading by saving energy as well as emerging and restructuring, and consequently found a new approach for China to fully raise energy efficiency and to realize the industry structure upgrade and optimizationThe first part of this thesis analyzes the economic implication of energy constraint. Under the assumption that there is no technogical progress , the research finds that the energy constraint causes inefficient short-term economic choice, which provides the basis for the discussions on industry structure upgrading and optimizing under energy contraint. In fact,, the essence of industry structure upgrading and optimizing under energy constraint is how to establish an energy saving mechanism that can force individuals, enterprises and government to actively participate in energy conservation from technology, structure and institution aspects, and consequently realize the industry structure upgrade and optimization.The second part is empirical analysis. Based on the present situation of energy structure in China, the thesis has constructed an evaluating indicator system for sustainable development of energy supply; with which it launches the empirical analysis on present energy supply situation in China The research discovers that the industrial connections among energy industries (coal, electricity, oil, gas) can affect the industry structure upgrading and optimizing through the energy price mechanism and the market structure mechanism. Then, the thesis proposes the methods and approaches of constructing sustainable energy supply systems based on Japan's experience on energy constraint procession By utilizing the DEA method, it has estimated the energy efficiency disparities among different industries and different regions, and tested on the influencing factors. Learning from international experience, this thesis puts forward the development strategy of promoting the industry structure upgrading in China.The third part of this thesis is case study. From the perspective of industrial connection, the thesis, taking as an example the industry development before and after the restructure of the Shenma Pingmei Group in Pingdingshan Coal Co., Ltd., has pointed out that emerging and restructuring will draw the strong points of other enterprise to offset one's own weakness, making the Group scale of economies, widening its industry chain and consequently avoiding the competition among the same industries and the redundant reconstruction. The case provides an reference for enterprises how to undertake structure upgrading and optimizing by emerging and restructuring as well as energy saving.The main conclusions of the paper are: (1) with the assumption that there is no technological progress, energy constraint will lead to short-term inefficient economic choice. The reason is that the producing behavior of individuals does not optimize the intertemporal factor substitute on energy aggregate, which will cause the loss of economic efficiency. (2)Technological progress is the optimal path to overcome energy constraint. It can not only enhance structure upgrade of energy industry by raising usable energy aggregate, increasing the productivity of factors and searching for energy substitute, but also promote the structure upgrade of non energy industries by innovating new products and improving working process to transform traditional industries and create new industries (3) The structure factor has very significant influence on energy efficiency. The influence lies in three-time industrial structures, the structure within an industry, international industrial division, urban morphological structure, transportation model configuration, region spatial structure and so on. The systematic plans and step-by-step resolutions on these issues are the important approaches to realize energy saving. (4) Institutional energy saving is the core strategy to realize energy saving. A good institution is the one that makes scientific and reasonable plans on energy saving, which will be beneficial to strengthening the instruction, supervision and inspection on the energy conservation work, consequently making it onto an orderly track and directing the structure transformation in a way that is in favor of energy saving and promote technological progress and structure upgrade. (5) Enterprises can realize industry structure upgrade and optimization by emerging and restructuring as well as saving energy.The main innovations of this article are: (1) it provides a more comprehensive analysis on the mechanism of industry structure upgrade and optimization under the energy constraint; (2) it constructs an evaluating system of sustainable energy supply; (3) it introduces variables that affect energy saving into empirical analysis from the perspective of industries and regions. Those variables include technogical progress, institution, three-time industrial structure, international industrial division, urban morphological structure, transportation model etc; (4) it has analyzed how enterprises can promote the industry structure optimizing and upgrading by saving energy as well as emerging and restructuring.
