城市三元空间发展水平的特征及耦合关系研究——以广东省为例

The Characteristics and Coupling Relationship of Urban Ternary Space Development: A Case Study of Guangdong Province

城市的物理空间、信息空间和社会空间之间的协调发展促成了城市的发展,物理空间的交通流和信息空间的信息流是促进社会空间中经济发展的主要动力。以广东省为研究对象,从交通建设、信息化和创新力3个方面对城市三元空间的发展水平特征及耦合关系进行研究:首先,通过构建城市交通优势度评价体系对各城市物理空间发展水平进行评价;其次,从社交关系视角对城市网络结构进行分析,构建城市信息连接度评价体系,对各城市信息空间发展水平进行评价;然后,综合考虑城市间的创新联系和城市创新力的辐射效应,构建城市创新力评价体系,对各城市社会空间发展水平进行评价;最后,通过耦合关系分析揭示城市交通建设和信息化与创新力提升之间的关系。研究结果表明,交通建设和信息化对城市创新力的提升有一定的推动作用,广东省各城市在三元空间的发展上总体处于中度耦合中度协调阶段,且存在地区差异。

The coordinated development of urban physical space,information space and social space has contributed to the development of cities.The traffic flow in physical space and the information flow in information space are the main driving force to develop economics in social space.This paper intends to explore the characteristics and coupling relationship of urban ternary space development from transportation construction,informatization and innovation in a case study of Guangdong Province.Firstly,urban transport superiority evaluation system is constructed to evaluate the physical space development of cities.Secondly,the network structure of cities is analyzed from the perspective of social relations and urban information connectivity evaluation system is constructed to evaluate the information space development of cities.Then,considering the innovation relationship between cities and the radiation effect of urban innovation,urban innovation ability evaluation system is constructed to evaluate the social space development of cities.Finally,the relationship between transportation construction,informatization and innovation promotion is analyzed through the analysis of the coupling relationship.The results show that transportation construction and informatization are significant impetus to the improvement of urban innovation.The ternary space development of cities in Guangdong Province are generally moderately coupled and coordinated,and there are regional differences.
