【摘要】：基于1989—2012年广西89个县域经济数据,利用分解的Theil指数和马尔可夫链方法,探索欠发达省域差异的时空演变。结果表明:广西区域差异对地理尺度很敏感,县域间的差异最大,其次为地市间,区域间的发展最为平衡。三大区域内部差距的增大是促成广西整体差异拉大的主导力量。广西区域经济发展存在俱乐部趋同现象,2000—2012年间的更为显著,欠发达地区极有可能陷入"贫困陷阱"。区域间的两极分化趋势增强,趋同俱乐部总体上呈环状分布特征。高水平趋同俱乐部的分布逐渐由市辖区扩散到邻近的县域。低水平趋同俱乐部主要分布在桂西资源富集区。中高水平趋同俱乐部环绕高水平趋同俱乐部外围,而中低水平趋同俱乐部集中分布在中高水平趋同俱乐部外围。广西县域单元平稳者居多,向上转移有所增加。
[Abstract]:Based on the economic data of 89 counties in Guangxi from 1989 to 2012, using the decomposition of Theil index and Markov chain method, this paper explores the temporal and spatial evolution of regional differences in less developed provinces. The results show that regional differences in Guangxi are sensitive to geographical scale, and the differences among counties are the largest. Secondly, the regional development is the most balanced. The increase of the internal gap among the three regions is the leading force that contributes to the widening of the overall differences in Guangxi. There is a phenomenon of club convergence in the regional economic development of Guangxi, which is more significant in the period 2000-2012. Underdeveloped regions are at great risk of falling into the "poverty trap"... there is a growing trend of polarization among regions, The distribution of the high level convergent clubs gradually spread from the municipal district to the neighboring counties. The low level convergent clubs were mainly distributed in the resource rich areas of western Guangxi. The music department surrounds the high level convergent club periphery, The middle and low level convergent clubs are concentrated in the periphery of the middle and high level convergent clubs. The most of Guangxi county units are stable and the upward transfer is increasing.
