Exploring external urban relational processes: inter-city financial flows complementing global city-regions
区分了两种外部城市关系（等级腹地与网络腹地），并发现全球城市中的资本流动会增强其区域内邻近小城市的资本流入，对理论和政策有启示。
External urban relations are commonly described as one of two types: hierarchical local hinterlands (central place theory) and networked non-local hinterworlds (central flow theory), referred to as town-ness and city-ness, respectively. This paper builds on and develops these generic concepts to make them specifically relevant to today’s corporate globalization. The central place process is represented by multi-nodal global city-regions, and the central flow process is represented by inter-city capital investment flows. We find that capital flows in global cities increase flows to proximate smaller cities within their regions. This empirical link between city-ness and town-ness has theoretical and policy implications.
