We argue that trans-local knowledge connections positively impact local epistemic inventor communities in global cities, using patent citations as an indicator of global knowledge connectivity. Patented inventions have become more concentrated in the most internationally connected global cities, increasing inter-regional inequality. We identify two dimensions of knowledge connectivity: the compatibility of connections between similar profiles of technological knowledge, and the geographical diversity of knowledge connections between differently specialized global cities. We suggest that interaction between local and international inventor epistemic communities is now a vital driver of local innovation in global cities, and interregional inequality between these and other cities.

国际知识连通性和创新日益集中在全球主要城市

我们认为，利用专利引用作为全球知识连通性的指标，跨地方知识联系对全球城市的当地认知发明者社区产生积极影响。专利发明越来越集中在国际联系最紧密的全球城市，从而加剧了区域间的不平等。我们确定了知识连通性的两个维度：相似技术知识之间连接的兼容性，以及不同专业化全球城市之间知识连接的地理多样性。我们认为，本地和国际发明家认知社区之间的互动现在是全球城市本地创新以及这些城市与其他城市之间区域间不平等的重要驱动力。
