中国区域可持续发展综合优势能力空间关联分析

采用空间统计方法研究了中国31个省、市、自治区的可持续发展综合优势能力的空间关联关系，结果显示中国可持续发展的总资产能力、总负债能力和综合优势能力均存在较强的空间依赖性。综合优势能力Z值与总资产Z值存在显著正相关（R=0.944），而与总负债Z值存在显著的负相关（R=-0.952）。利用综合优势能力空间关联Z值对中国可持续发展能力进行初步的分区，并采用古典聚类（K means）方法对中国可持续发展能力进行同质性研究，利用K聚类结果对空间聚类（G统计）结果进行修正，将中国可持续发展能力划分为3种区域类型：中国东部沿海强发展区域、中国中部中等发展区域和中国西部弱发展区域。分区结果与中国传统的东部、中部、西部区域划分基本对应，东部沿海省市除海南和广西处于中等发展类型外，其他省市均处在强发展类型之列，中国中部全部省市均处于中等发展类型而中国西部全部省市均处于弱发展类型。

ANALYSIS ON SPATIAL RELATIONSHIPS IN THE OVERALL STRENGTH OF REGIONAL SUSTAINABLE DEVELOPMENT IN CHINA

In this paper,spatial statistical method was used to study the spatial relationships in overall strength and capacity of sustainable development of different regions in China,including 31 provinces,municipalities and autonomous regions.The spatial dependence of all the total assets,total debts and overall strength and capacity of sustainable development in China was obvious.The positive significant correlation was observed between the Z value of overall strength and capacity and total assets(R= 0.944),while the negative significant correlation between the Z value and total debts.The cluster of sustainable development capacity in China was firstly given based on the Z values of overall strength and capacity.Then,the spatial cluster results were adjusted according to the results of K-means cluster.Finally,3 types of sustainable development capacity were compartmentalized in China,i.e.,developed type of eastern and coastal regions,developing type of center regions and lower development type of western regions of China.The results obtained in the present study were in accordance with the traditional division of regions in China.All of the provinces and cities of Eastern China belong to developed type except for Guangxi and Hainan belonging to developing type,the provinces and cities in the central belong to developing type and all of western provinces and cities belong to lower development type.
