综合考虑经济发展水平指标、居民生活水平指标和经济结构指标，利用加权主成分分析方法、自然断点法及趋势分析法对多时点数据进行分析，揭示河南省县域经济实力时空差异特征。研究表明：经济发展水平与经济结构及居民生活水平具有较高的相关度，河南省县域经济实力的空间地域差异及空间分异显著，但近10年来总体变化趋势不大；近十年河南省各类型县域的数量波动较大，其空间分布格局的演变由原来典型的“单一核心”结构发展成明显的“多核心”结构；河南省县域总体经济实力普遍较低，且发达县城和不发达县域两极分化显著，两者在经济实力排名上虽有波动，但变化不大；核心城市的带动效应显著，河南省县域经济实力增长呈现明显的“双核心”驱动。

Considering the various types of indicators of economic development level, living standards and e- conomic （industrial） structure, using methods of weighted PCA, natural breakpoint and trend analysis to analyze multi-time-points data, revealed the tempo-spatial disparities of county economic strength in Henan Province. The main findings are shown as follows： The economic development level is closely related to economic （industrial） structure and living standard, but the spatial differentiation of county＇ s economic strength have been significant, and the overall trend is not so obvious in the past decade in Henan Province; In the recent 10 years, the number of various types of counties show considerable changes, and the evolution of spatial distribution pattern are character- ized by shifting from the typical single-core structure into apparently the multi-core structure in Henan Province; The overall economic strength of counties is generally low in Henan Province and displays significant polarization between developed and undeveloped counties which have not obvious fluctuations in economic strength rankings; The driving effects of ＂dual-central-cities＂ are of significant in Henan Province.
