Abstract:

A rise in China’s regional carbon dioxide emission becomes a focus. This paper calculates the quantities of carbon dioxide emission in 30 provinces from 1997 to 2007, and applies a spatial economic measure to study the β convergence of China’s regional carbon dioxide emission. Revealed by the 11-year’s data, there is no absolute convergence, but conditional converse at a speed of 1.04% after controlling economic growing speed and remaining energy consuming structures. Temporally, a notable spatial relativity happened during 1997 to 2002, and absolute and conditional convergence also existed at a speed of 2.49% and 1.74%, respectively. During 2002 to 2007, there is no spatial relativity and no absolute and conditional convergence. Furthermore, economic growth speed and coal consumption ratio have an impact on carbon dioxide emission. It is a workable means to keep a stable economic growth and to optimize the energy consumption structures.
