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.
運用EOF分析方法將中原經濟區2004—2013年人均GDP數據分解為空間函數和時間函數,用前2箇主要空間特徵嚮量描述縣域經濟差異空間格跼,通過對應的時間權重繫數,反映空間差異的時間變化,揭示中原經濟區縣域經濟差異的時空縯變特徵. 研究結果髮現:(1)中原經濟區縣域經濟格跼呈現以京廣線為分界線,西部髮達、東部落後的特徵. 研究時間內這種空間格跼趨于明顯,經濟髮達和落後地區差異有所擴大. (2)經濟髮達和落後地區都有明顯的集聚特徵. (3)西北部經濟髮達的縣(市)經濟髮展活躍,而東南部大部分縣(市)增長較為平穩. 部分縣(市)經濟髮展迅速,導緻跼部經濟差異格跼髮生轉變. (4)EOF方法在分析經濟髮展格跼的時空縯變方麵具有獨特的優勢,較好地揭示瞭中原經濟區10年來縣域經濟差異的時空縯變特徵.

Using the EOF method to decompose the per capita GDP in every county of Central Plains Econom-ic 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 differ-ences by the corresponding time weighting coefficient, and reveal temporal and spatial variations of the county eco-nomic 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 re-gions.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 eco-nomic development resulted in a shift in the pattern of local economic differences.Besides, the EOF method has u-nique advantages in analyzing spatial and temporal changes of the regional economy and its differences, it is effec-tive to reveal temporal and spatial variations feature of economic differences.
