山西省区域发展质量差异的时空分析

Temporal and spatial analysis difference of regional development quality in Shanxi Province

基于区域发展质量概念界定的基础上,分别从社会进步、经济增长和环境优化等3个维度,共30个指标,构建出区域发展质量的综合指标体系.通过运用熵值法以及相关差异指数等方法,对山西省各地级市的区域发展质量及其差异进行定量测度,并借助空间分析工具ArcGIS对研究结果进行聚类分析和空间表达,以此揭示2004~2012年山西省区域发展质量差异的时空演变轨迹.通过分析发现：1）自国家实施＂中部崛起＂战略以来,山西省区域发展质量提高,发展模式趋于协调;2）全省区域发展质量差异表现为先扩大后缩小的变化趋势,总体上呈现扩大态势,且主要表现为社会进步差异;3）省域内部各地市质量等级差异明显,空间极化增强;4）区域发展质量与发展速度具有高度的相关性,且在空间表现为大同市、临汾市和运城市呈现向下发散,忻州市、吕梁市和晋中市呈现向上收敛现象,而太原市和阳泉市呈现向下收敛,长治市、晋城市和朔州市则呈现向上发散趋势.

On the base of the definition of the regional development quality,the comprehensive index system of regional development quality is constructed from the three aspects of social progress,economic growth and environmental optimization.It includes 30 index dates.The regional development quality of the cities in Shanxi Province is measured quantitatively by entropy method and related difference index.Besides,the space-time developments track of the differences among cities in Shanxi Province is revealed through cluster analysis and space expression of ArcGIS.The results show：1）after the strategy of the Central Region Rise,the quality level of Shanxi Province regional development improved constantly,and the developmental models become more and more coordinate;2）the trend of the differences among cities in Shanxi Province becomes enlarge,from enlargement to reduction,and mainly for the differences in social progress;3）the rank difference among different cities in Shanxi Province is obvious,and spatial polarization enhancement;4）there exists correlation between the quality and speed of development of regional development.The trend of Datong,Linfen and Yuncheng shows divergent downward,Xinzhou,Lüliang and Jinzhong is dominated by divergent upward,Taiyuan and Yangquan is dominated by divergent downward,Changzhi,Jincheng and Suozhou shows divergent upward.
