城市创新能力与城市化水平时空耦合协调机制分析——基于我国2002—2017年地级以上城市数据

Spatial temporal coupling and driving mechanism of innovation capability and urbanization level of cities in China

综合运用熵值法、耦合协调度模型、地理探测器等方法对2002—2017年我国286个地级及以上城市的创新能力与城市化水平耦合协调度的时空演化特征进行分析,并探讨其驱动机制。研究结果表明:我国城市创新能力持续上升且区域差距明显,空间格局发生显著变化,城市化水平显著提升且区域差距明显。我国城市创新能力与城市化水平协调度呈上升趋势,在类型划分上,创新能力低、城市化水平低、协调度低是最主要的分布类型;在类型转化上,空间变化显著,低低低转高高高是最主要的类型,同时各转化类别存在一定的空间集聚性。城市创新能力与城市化水平的耦合协调发展是政策调控力、经济驱动力、资源凝聚力下各要素相互作用的结果,其中经济驱动力是最主要的影响因素。

In this paper,entropy method,coupling coordination model,geographic detector are used to analyze the spatial-temporal evolution characteristics of the coupling between innovation ability and urbanization level of 286 cities at prefecture level and above in China from 2002 to 2017,and to explore its driving mechanism.The results indicate that the urban innovation ability of China sustains accelerating the rise,the regional disparity is evident,and the spatial structure has changed significantly.China’s urbanization level has promoted significantly,and the regional disparity of urbanization level is obvious.The coordination degree between urban innovation ability and urbanization level in China maintains an upward trend.The middle and low level types become the main distribution type in the central and western regions.In terms of spatial classification,LLL is the main distribution type.From the perspective of type transformation,the spatial change is significant and LLL to HHH is the main type.Furthermore,each transformation type has a certain degree of spatial agglomeration.Based on the geographic detector model,the research shows that the coupling and coordinated development of urban innovation ability and urbanization level is the result of the interaction of various factors in policy regulation,economic driving force and resource cohesion,and the economic driving force is the most important driving force.
