| 摘 要： | 为分析河南省10年来区域经济差异的时空演变,以该省1998-2007年各县逐年人均GDP数据为测度指标,尝试采用在气象学中已被广泛应用的自然正交函数(EOF)方法把人均GDP距平阵正交分解为空间甬数场及时间函数.结果表明:EOF方法不仅可以描述整个研究时段内区域经济分异的整体格局,而且可以反映某一区域经济分异格局所占的比重以及该分异格局随时间的连续变化特征,与传统的分析方法相比,EOF方法具有比较明显的优势.

| Abstract: | To analyze the spatial-temporal evolution of regional economic disparities,this paper first attempts the EOF method which is widdly applied in meteorology to decompose the anomalous matrix of per capita GDP into spatial functions and time functions using the per capita GDP data in every county in Henan from 1998 to 2007 as measure index. The results show that the EOF method describes not only the global structure of regional economic disparities in the whole period,but also reflects the weights of some stru... |
