摘要： 城市间的互动往来不仅体现在人流、物流、信息流等物质层面，更体现在文化、思想、情感、精神等层面，且它们错综交织而难分。城市际性问题归根到底是边界问题。去边界化、去中心化、去同质化是未来城市际性研究和实践要考虑的三个关键问题。随着城市和区域流动日趋频繁，虽然城市空间和活动交互频繁，但还是城市中人的交互作用。城市际性与人的主体性的关系问题仍是核心。打破学科和地域界限，使思想、知识像其他要素一样自由流动，才能从实质上推进城市际性的理论研究和实践。

Abstract: The interaction between cities is not only reflected in people, logistics, information flow and other material aspects, but also in the cultural, ideological, emotional, spiritual and other aspects, and they are intricate and inseparable. In the ?nal analysis, the problem of interurbanity is the problem of boundary. The three key issues to be considered in the future research and practice of inter city are the elimination of boundary, decentralization and homogeneity. With the increasing ?ow of cities and regions, although the interaction of urban space and activities is frequent, it is still the interaction of people in cities. The relationship between interurbanity and human subjectivity is still the core. Only by breaking the boundaries of disciplines and regions, and making thoughts and knowledge ?ow freely like other elements, can we promote the theoretical research and practice of interurbanity in essence.
