A multi-sector model of relatedness, growth and industry clustering
构建了一个多部门模型，将技术关联性纳入内生增长和地理经济学框架，解释企业为何偏好集聚在技术兼容的集群中，且核心与外围地区均可形成集群。
Abstract This article builds an understanding of regional innovation specialisation by developing a multi-sector model with endogenous growth through quality improving innovations and spillovers from related technologies. The model provides an approach to incorporate the relatedness literature within the mainstream theoretical frameworks of endogenous growth and economic geography. Each firm’s technology sector and the location of other firms play a role in each firm’s ability to improve its own technology. As a result, firms prefer to co-locate in technologically compatible clusters. Without relying on scale assumptions, the model for the first time coherently links related variety knowledge spillovers to mainstream urban economic frameworks and demonstrates that clustering is possible in both core and peripheral areas.
