摘要
以县域(含县、县级市、市辖区)为基础研究单元,选择国内生产总值、年末总人口和人均GDP为基本指标,运用Theil指数、探索性空间分析和多元线性回归等方法研究2005—2014年河南省县域经济的时空差异、格局演变以及动力机制。研究结果表明:1河南省区域经济总差异呈现"先减小,后增大,再减小"的趋势,省辖市间的差异明显大于省辖市内的差异。2省辖市之间的经济差异基本呈现出中原城市群地区和非中原城市群地区的差异;省辖市内的经济差异最大的是洛阳市,最小的是漯河市,濮阳市、焦作市、周口市、三门峡市各年份内部经济差异变化明显。3县域单元经济发展水平呈现出显著的空间正相关;通过Getis-Ord G*i分析发现,热点区和次热点区主要分布在豫西北地区,冷点区和次冷点区主要分布在豫东地区,豫西南地区冷点区从无到有并逐渐增多。4在多元线性回归中发现,二三产业比重是影响区域经济发展水平最重要的因素,政府政策因素的影响次之。
Taking counties( including counties,county-level cities and municipal districts) as the basic research unit,selecting the gross domestic product,population by the end and average gross domestic product as the basic indicators,used Theil index,exploratory spatial analysis method and multiple linear regression to analyse the temporal-spatial economic differences,pattern of evolution and dynamic mechanism from 2005 to 2014 in Henan Province. The results are shown as follows. Firstly,the regional economic differences of Henan presents "First decrease,then increase,decrease again"and the differences among cities greater than the differences of cities. Secondly,the differences among cities show the Zhongyuan Urban Agglomeration with other cities in Henan. Luoyang is always the biggest city in the internal economic differences of cities,the smallest is Luohe. Puyang,Jiaozuo,Zhoukou,Sanmenxia change obviously in internal economy difference. Thirdly,the economic level of counties present obviously positive correlation from 2005 to 2014,through the analysis of Getis-Ord G*ifind that hot spot area and secondary hot spot area mainly distributed in the northwest regions,cold spot area and secondary cold spot area are mainly distributed in the eastern region,cold spots from scratch and gradually increase in southwest. Finally,multiple linear regression analysis found that the proportion of secondary and tertiary industries was the most important factors which affecting the development of regional economy,the government's policy in the second.
