河南省县域经济空间结构动态演变分析

摘要

Selecting per capita GDP as the evaluation variable,using spatial statistical analysis method,the author analysed the evolution process of global and local economic spatial structure at the county level in Henan from 1980 to 2010. At the same time the economic centers of gravity for each time were calculated. The result shows that in the past 30 years the economic spatial structure had an gradual transition from random mode to aggregation mode and the degree of aggregation has been strengthening. The unbalanced nature of economic development in Henan is mainly in the east-west direction,the difference in the north-south direction is relatively small. Furthermore,there is a trend that the difference in the east-west direction is expanding and the north-south direction is narrowing.%以河南省126个县域为研究对象，选取人均GDP作为评价指标，采用空间统计分析方法对1980，1985，1990，1995，2000，2005，2010年7个时期河南省县域经济空间结构的全局和局部演变特征进行了研究，并计算了河南省经济重心的迁移轨迹。结果表明：30年来，河南省县域经济的空间分布由随机模式逐步过渡到聚集模式，且聚集程度在不断加强；1980-1990年，主要形成了若干个以市区为中心的高低经济孤立区，随着工业化进程的不断推进，河南县域经济在空间上开始聚集，目前形成豫西北经济发达区和豫东、豫东南两个经济萧条区，并且两个经济萧条区有进一步合拢的趋势；河南省经济发展的不均衡性主要体现在东西方向，南北方向的差异相对较小，而且东西差异有不断扩大的趋势，南北差异有逐渐缩小的趋势。
