摘　　要：运用EOF分析方法将中原经济区2004—2013年人均GDP数据分解为空间函数和时间函数,用前2个主要空间特征向量描述县域经济差异空间格局,通过对应的时间权重系数,反映空间差异的时间变化,揭示中原经济区县域经济差异的时空演变特征。研究结果发现:(1)中原经济区县域经济格局呈现以京广线为分界线,西部发达、东部落后的特征。研究时间内这种空间格局趋于明显,经济发达和落后地区差异有所扩大。(2)经济发达和落后地区都有明显的集聚特征。(3)西北部经济发达的县(市)经济发展活跃,而东南部大部分县(市)增长较为平稳。部分县(市)经济发展迅速,导致局部经济差异格局发生转变。(4)EOF方法在分析经济发展格局的时空演变方面具有独特的优势,较好地揭示了中原经济区10年来县域经济差异的时空演变特征。Using the EOF method to decompose the per capita GDP in every county of Central Plains Economic Region （CPER）from 2003 to 2012 into spatial functions and time functions, and describe the spatial pattern of county economic differences by the first two major space feature vectors, represent the time changes of spatial differences by the corresponding time weighting coefficient, and reveal temporal and spatial variations of the county economic differences in Central Plains Economic Region. Several important conclusions was found in this paper. First, Beijing-Guangzhou Railway was the dividing line of Central Plains Economic Region county economic pattern, the western was developed and the eastern was underdeveloped. This spatial pattern within the study time was becoming more apparent, the economic disparities between developed and undeveloped areas has expanded. Second, there were obvious aggregation feature in both the economically developed regions and economically underdeveloped regions. Third, economic development was active in northwestern economically developed counties （cities） in the northwest and most of southeast counties （cities） growth was relatively stable. Some counties＇ （cities） rapid economic development resulted in a shift in the pattern of local economic differences. Besides, the EOF method has unique advantages in analyzing spatial and temporal changes of the regional economy and its differences, it is effective to reveal temporal and spatial variations feature of economic differences.
