Diversity in brokerage: how do gateway cities interlink their hinterlands?
探讨门户城市作为中介如何以多种方式连接全球腹地，在传统的企业控制和服务功能之外，增加了物流、工业加工和知识传播维度，并以布宜诺斯艾利斯、开普敦和新加坡为例展示这种多样性。
The article invites readers to rethink cities in economic networks against the backdrop of the many ways in which ‘gateway cities’, serving as brokers, interlink their respective hinterlands globally. It adds logistics, industrial processing and knowledge transmission to the more established gateway dimensions of corporate control and related service provision. This open heuristic is applied to Buenos Aires (Argentina), Cape Town (South Africa) and Singapore, which are vital nodes for the oil and gas industry. In addition to showing how diverse brokerage by cities is, the article calls for qualitative research to complement the insights on city networks generated by quantitative assessments.
