基于1985—2010年中国29个地区的面板数据,对能源强度的收敛性进行了分析.在研究方法上,除了考察常见的β收敛和σ收敛外,还引入排名一致性系数对γ收敛进行了检验.研究结果表明,中国地区能源强度存在显著的β收敛和γ收敛;对于盯收敛,在采用变异系数法进行检验时,并未反映出显著的σ收敛特征,但采用核密度估计则较好的验证了我国地区能源强度的σ收敛性.
Based on the panel data of 29 regions from 1985 to 2010, we study the convergence of energy intensity. Regarding as the methodology, we introduce the convergence after adopting beta-convergence and sigma-convergence. The results that the regional energy intensity convergence is significantly existed. regional gamma- indicate
