采用由人均、地均因子组成的经济密度综合评价模型,分析中原经济区县域经济密度空间分异特征,从定性与定量相结合的视角阐释经济密度分异的机理。结果显示:11995年以来中原经济区县域经济密度水平相似的区域在空间存在集聚分布,而且空间差异性在不断减小。2局部空间自相关显著的区域主要以HH区和LL区为主,这表明中原经济区经济密度相关性显著的县域虽然存在着扩散,但以集聚为主。3从影响因子看,人均影响因子所起作用大于地均影响因子,且在人均影响因子中人均第一产业产值、人均第三产业产值、人均社会零售品总额、人均城乡居民储蓄余额等因子起主要作用。4从回归模型看,土地投入、产业规模及交通运输条件对中原经济区经济密度的影响为正,劳动力资源、财政投入、人口素质对经济密度的影响为负;其中劳动力资源、产业规模、财政投入、产业结构因素的作用较强。
The economic density is one of the most important economic indicators which can reflex economic level andeconomic quality. Based on the comprehensive evaluation model composed by per capita and land factors, this papergives a systematic and in-depth analysis on spatial characteristics of CPER at county level, and gives a mechanismexplanation from the combination of theory and practice. The results show that, the spatial agglomeration phenomenon ofeconomic density level in CPER at county level is obvious, and its agglomeration degree is increasingly strengthened.From the local spatial autocorrelation, HH and LL is the governing region, which shows that the spatial pattern ofeconomic density is dominated by agglomeration. The paper also finds that, the per capita influencing factors are moreimportant than land density influencing factors, and the influencing factors such as per capita primary industry, tertiaryindustry, total retail sales of consumer goods, residents' saving deposits of financial institutions in urban and rural areasplay an important role. From the regression model, the influencing factors of land input, transportation and industrialscale are positive to the economic density, while the influencing factors such as labor resources, financial investment,information level, population' s education level are negative to it. And labor resources, industrial scale, financialinvestment are the important influencing factors of economic density in CPER.
