Chinese Regional Energy Consumption Difference Of Empirical Research

The development of our society is closely related to the use of all kinds of energies. With our development and utilization of various energies, the problem of energy becomes increasingly obvious. The shortage of energy and various environmental problems caused by the development and utilization of energies have become the most important focus of the world. The fact of the increasing amount of the usage of energy of china draw the world's attention, while there is an increasing demand for reducing the emission of CO2 and responding to climate change.So reducing the energy consumption intensity is not only the demand of china's own sustainable development, but also the china's responsibility of dealing with climate change. It is also meaningful and necessary to research on the factors influencing the energy consumption intensity.Firstly, we construction the regression model of the factors influencing the energy consumption intensity to discuss the effects of all the factors influencing the energy intensity based on the induced technological innovation of energy price and the"rebound effect"of technological innovation, after describing the situations of energy intensity and all the factors influencing the energy intensity, including the level of economy development, GDP, industrial structure, energy consumption structure, urbanization, FDI, export, energy price, technological innovation as well as the policy and system factor etc.Secondly, we identified the final model for decomposition with step-wise regression analysis. What's more, we use the number of patents authorized, the expenditures input in scientific and technological activities (internal expenditures) and the population engaged in scientific and technological activities to describe the factor of technological innovation for the stability testing. After the analysis, we draw the conclusion that the level of economic development, industrial structure, urbanization, FDI, energy price, technological innovation and the policy and system factor are the most significant factors.Thirdly, we use the Blinder-Oaxaca decomposition for liner regression model to analyze the factors influencing the gap of energy intensity between different regions on the basis of the regression of high-energy-consumption areas and low-energy-consumption areas. We find the fact that all the factors have significant influence on the energy intensity in high-energy-consumption areas and low-energy-consumption areas on the condition of deferent indications of technological innovation although the degree of the impact except the urbanization are deferent in high-energy-consumption areas and low-energy-consumption areas. As for urbanization, its influence on energy intensity at low-energy-consumption areas is not significant, but it does be significant at high-energy-consumption areas. Furthermore, the energy intensity will increase with the improvement of urbanization at high-energy-consumption areas. On the one hand, this is because the energy intensity per capita of people at urban area is much higher than that of people at rural area. On the other hand, it is also the problem indication of urbanization in china especially at high-energy-consumption areas. Besides, the linear term and quadratic term of the technological innovation factor are both significant under the condition of patents authorized. But the quadratic term become insignificant in the case of the expenditures input in scientific and technological activities (internal expenditures). Not only the linear term but also the quadratic term is both not significant in the case of the population engaged in scientific and technological activities. All these above underline there are big problems in the science and technology input and output mechanism at high-energy-consumption areas.As to the decomposition of factors influencing the energy intensity at deferent areas, we find the total decompositions are mostly similar on the condition of deferent indications of technological innovation and the level of economic development , FDI and technological innovation are the most important factors of all influencing the gap in energy intensity between regions. According to the types of the factors, economic one is the most important, and then is the technological factor and the last is the political and systematical ones. The difference is the degree of contribution as to a certain factor in the case of deferent indications of technological innovation. We find that the decomposition in the situation of the expenditures input in scientific and technological activities (internal expenditures) are some kind of different from the other two situations.In the situation of the expenditures input in scientific and technological activities (internal expenditures), the contribution of economic development and the total contribution of economic factors are much smaller than in the other two situation while the contribution of technological innovation is much higher than in the other two situation.Lastly, we put forward some policy suggestions to reduce the energy consumption intensity in China and narrow the gap of energy intensity between high-energy-consumption areas and low-energy-consumption areas. We should adjust the industrial structure and promote economic development. During the process of promoting the urbanization on a fairly high speed, the government should encourage sustainable consumption and actively develop sustainable traffic and sustainable construction. According to FDI, we should not only expand the scale of foreign investment, but also improve the quality of foreign investment. We should actively promote the reform of energy price's formation and adjustment mechanism. As for technological innovation, the input on science and technology should be increased steadily and the innovation of energy conservation must be promoted energetically .what's more, the research and development of renewable energy and clean energy have to be accelerated. Furthermore, the government should also improve and perfect the policy of fiscal investment and financial subsidies on energy conservation and improve the government procurement system for energy-saving products. In the addition, taxation system reform should be improved and the government must accelerate the formulation of all kinds of energy relevant laws and policies as well as strengthen the supervision of the law's enforcement.
