云南省区域经济差异时空演变特征

The Space-Time Evolution of Regional Economic Diversity in Yunnan Province

以地带、市级、县级三个尺度地域为分析的基本空间单元,基于云南省1985—2012年统计年鉴人均GDP数据,采用人口加权变异系数、基尼系数、锡尔系数统计分析方法,对云南省近30年来的区域经济差异演变进行定量分析,并运用锡尔系数的分解,探讨了云南省区域经济差异的地域构成。结果发现:1云南省区域经济差异演变呈现倒"U"型特征,区域经济差异经历先扩大再缩小的过程,区域之间发展差异波动较大;2一阶段锡尔系数分解显示:滇中地区锡尔系数远远大于其他地区,滇中内部之间经济发展二元结构突出,是全省区域经济差异产生的主要来源;3二阶段锡尔系数分解表明:不同尺度地域单元下,经济发展呈现出地市内差异大于地市间差异、地市间差异大于地带间差异规律,地市内和地市间差异对整体差异的贡献率呈现波浪式变化,波动较地带间大,地市内的差异主导着全省区域经济差异走向。

As zone, municipal, county-level three scale regions the basic spatial analysis unit, Be based on the statistical yearbook of Yunnan province 1985-2012 per-capita GDP data, using population weighted coefficient of variation, Gini coefficient and Theil coefficient statistics analysis methods, analyzing regional inequalities to the evolution of the nearly 30 years in Yunnan province, and using the decomposition of Theil coefficient, discussing regional economic differences of Yunnan province. The results show： （1） the evolution of regional economic difference of Yurman province shows an inverted ＂U＂ type, the difference of regional economic Enlarged first and then narrowed, regional development Presents difference fluctuations;（2） a stage Theil decomposition shows： The central ofYunnan Theil coefficient is the main sources of the regional economic differences and much larger than other regions, the internal economic development of two element structure is prominent,（3） the two stage Theil decomposition shows that： regional units with different scales, the economic development of a city the difference is larger than the difference between the city and city the difference is larger than the difference between the region difference, differences of contribution to the city and the city on the overall difference ratio shows a wave type change, fluctuation is large difference to the city zone, leading the trend of regional economic differences.
