The Spatial Correlation, Convergence And Determinants Of Environment-Energy Efficiency In China

Since the reform and opening up30years ago, China’s economy has experienced rapid development, accompanied by high energy consumption and high pollution. For the evaluation of the economic development,we should not only focus on quantity, but also should focus on quality. So we put forward the Environment-Energy Efficiency to be a more comprehensive and objective indicator to the economy development.Further more, we emphasize on the influences of the agglomeration on the Environment-Energy Efficiency, which will help to judge the effectiveness of industrial policy and urban policy over the past decade and provide a theoretical reference for relevant policy making in the future.Considering of the influences of the agglomeration on the Environment-Energy Efficiency, there may be both economies of scale and diseconomies of scale.Therefore our research has a great theoretical significance as well as a strong practical significance.Based on the DEA model that is under the assumption of input-oriented and variable returns to scale,combining with window analysis technique,we use2000-2010provincial panel data to measure the Environment-Energy Efficiency of all the Chinese provinces except of Tibet and Taiwan,and analyzes the influences of the industrial agglomeration and urban agglomeration. The results showed that:from2000to2008, China’s economy has experienced rapid development,with the Environment-Energy Efficiency increasing,the spatial correlation strengthening and regional gap gradually narrowing; while the efficiency is significantly reduced After2008companied by the spatial correlation weakening and Regional differences enlarging. On the whole, China’s Environment-Energy Efficiency presents a descending trend from the southeast to the west.Meanwhile inefficient areas are extending from the North to the middle and the southwest. The industrial agglomeration will help to improve the Environment-Energy Efficiency, while urban agglomeration lead to the decline of the Environment-Energy Efficiency Further more,the industrial agglomeration and urban agglomeration has different effects on different regions.For the conclusions of this paper,we suggest that we should:Improve the level of economic development; Transform the economic growth mode; Increase the degree of opening to the outside world; Improve the efficiency of scientific research; Accelerate industrial restructuring; Coordinate regional development and build a new type of urbanization.
