Synthesising the endogenous-centred evolutionary economic geography perspective, and the globally oriented ‘global pipelines’ and global production networks frameworks, this article develops the ‘boundary spanner’ concept to propose a theoretical framework to illustrate how resourceful actors, as boundary spanners, globalise clusters and in turn drive cluster evolution. This framework comprises four interrelated cluster boundary-spanning functions, namely, discursive construction, innovation promotion, production coordination and market reach. This article aims to advance the cluster literature by unpacking how clusters’ global connections are constructed and maintained, conceptualising the multidimensional role of the agency of boundary spanners and demonstrating boundary spanners’ contributions to cluster evolution.

综合以内生为中心的演化经济地理学视角，以及面向全球的“全球管道”和全球生产网络框架，本文发展了“边界扳手”概念，提出了一个理论框架来说明资源丰富的行为者作为边界扳手如何使集群全球化进而推动集群演进。该框架包括四个相互关联的集群跨界功能，即话语构建、创新促进、生产协调和市场覆盖。本文旨在通过解开集群的全局连接是如何构建和维护的，概念化边界生成器代理的多维作用并展示边界生成器对集群演化的贡献来推进集群文献。
