[Abstract]:Urbanization and industrial structure adjustment and upgrading are the inevitable results of social and economic development. At the present stage, China's urbanization and industrial structure upgrading are in a period of rapid development, with strong demand for energy and resources. The pressure of energy resources and environmental pollution caused by excessive consumption of energy will continue to increase. Under the background of the shortage of global energy resources and the increasingly serious environmental pollution problems, All these bring great pressure to the sustainability of energy resources and ecological environment security. Urbanization and industrial structure adjustment have two opposite effects on energy consumption. How to understand the impact of urbanization and industrial structure change on energy consumption, and how to promote urbanization and industrial structure adjustment and upgrading process actively and steadily, It is of great significance to improve energy efficiency and reduce energy consumption to realize energy saving and emission reduction and to establish a resource-conserving environment-friendly society. Based on the urbanization, industrial structure and energy efficiency data of 30 provinces and cities in China from 1995 to 2013, this paper constructs a spatial panel Dobbin model. Because the economic spatial weight matrix is more consistent with the reality than the geographical weight matrix and the economic intensity matrix alone, the following conclusions are based on the fixed time of the economic spatial weight matrix. The results of the spatial panel Dobbin model with random effects. The empirical results show that the Moran'I statistics of energy efficiency are significantly positive, indicating that there is a positive correlation between energy efficiency and spatial concentration. From the result of parameter estimation, the coefficient of spatial effect is positive and significant. The effect of urbanization rate on energy efficiency is negative, but the spatial spillover effect on energy efficiency of neighboring provinces and cities is positive. The change of secondary industry proportion and tertiary industry proportion in industrial structure has the opposite effect on energy efficiency. At the same time, the spatial spillover effect of them on neighboring provinces and cities was significantly negative, and the spatial spillover effect of secondary industry proportion on energy efficiency of adjacent provinces and cities was significantly higher than that of tertiary industry. From the result that the influence of urbanization and industrial structure on energy efficiency is decomposed into direct effect and indirect effect, urbanization has obvious positive indirect effect and negative direct effect on energy efficiency. In the industrial structure, the proportion of the secondary industry has the greatest impact on energy efficiency, its direct and indirect effects are significantly negative; The effect of the proportion of the tertiary industry on energy efficiency is significantly positive and the indirect effect is larger than that of the direct effect, but the influence coefficient is smaller than that of the secondary industry. It shows that in the process of new-type urbanization, it is necessary to develop new type of urbanization to save energy and environmental protection, and to improve the energy saving of urbanization. Speeding up the adjustment and upgrading of industrial structure, improving the quality of economic development, gradually reducing the proportion of secondary industry and developing the tertiary industry with lower energy consumption, the economic growth of our country can get out of the predicament of low energy efficiency.
