SPATIAL QUANTITATIVE ANALYSIS ON CHINA'S REGIONAL CARBON DIOXIDE EMISSION CONVERGENCE

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.
