中原经济区县域经济空间结构分析

Analysis of Spatial Economic Structure in Central Plains Economic Region at County Level

以中原经济区232个县域为研究对象,选取人均GDP作为评价指标,采用自然裂点法对2010年县域的人均GDP数据进行了分级统计,并将中原经济区的县域经济划分为5种类型;然后采用空间统计分析方法对中原经济区县域经济的空间关联模式进行了分析。结果表明,中原经济区县域经济东西差异非常明显,以京广铁路为界,以西(包括京广线所经县市)为经济相对发达区,以东为相对落后区。中原经济区县域经济全局空间关联特征为聚集模式,在中原经济区县域经济的空间上形成了2个高高聚集区(1大1小)、2个低低聚集区(1大1小)、3个小的低高空心区和1个高低孤立区。

Selecting GDP per capita as the evaluation variable,the author used natural breaks method from the central plains economic zone of 232 counties as the research object,doing statistical classification of GDP per capita and dividing the county economy into five different types.Then the author analyzed the spatial autocorrelation mode of county economy in Central Plains Economic Region by using spatial statistical method.The results showed that there is an obvious difference in east-west direction bounded by Beijing-Guangzhou railway.The west of the railway is relatively developed and the east is relatively backward areas.The global spatial autocorrelation mode is aggregation mode in the Central Plains Economic Region,which formed two high-high aggregation areas,two low-low aggregation areas,three small low-high dispersion areas,and one high-low dispersion area.
