中原城市群县域创新水平空间分异及其影响因素

Spatial Pattern and Its Influencing Factors of Innovation Level at Country Scale in Central Plains Urban Agglomeration

以中原城市群中的194个县(市)作为研究单元,基于创新水平指标体系,运用Jenks Natural Breaks分类、探索性空间数据分析和地理探测器等方法,分析了2007年、2017年中原城市群创新水平的空间分异及其影响因素.结果表明:①研究区总体格局呈现出明显的东南-西北分异,高低区组合形成“一极三片区”的结构特点.②空间关联格局以显著HH区和显著LL区为主,显著HH区主要分布在以巩义市为核心的中部;显著LL主要在南部、东南部形成低值连片区.③从影响因素看,科技实力对创新水平分异发挥着核心支撑作用,经济实力和科技投入分别发挥着动力支撑和关键支撑作用.

At the county level,194 counties(cities)of the Central Plains urban agglomeration are used as the spatial research units.Based on the innovation level index system,this paper analyzed the spatial pattern and its influencing factors of innovation level in 2007 and 2017 by using Jenks Natural Breaks classification,exploratory spatial data analysis and geographical detector.The results were shown as follows.①There was an obvious spatial pattern from the southeast to the northwest.As a whole,the spatial pattern of“one pole and three areas”is formed by the combination of high and low areas.②From the perspective of spatial correlation,the agglomeration effect of significant HH area and significant LL area is obvious,and the significant HH area is mainly distributed in the central part with Gongyi City as the core,and the significant LL area is mainly distributed in the counties(cities)in the south and southeast regions.③From the perspective of influencing factors,scientific and technological strength plays a central supporting role in the differentiation of innovation levels,while economic strength and scientific and technological input play a power supporting role and a key supporting role.
