The Core–Periphery Model and Endogenous Growth: Stabilizing and Destabilizing Integration
将产品创新增长引入核心-边缘模型，研究增长与产业区位如何相互决定，发现增长是强大的向心力而知识溢出是离心力，降低思想贸易成本促进分散、降低商品贸易成本促进集聚，且集聚有利于两地增长。
We present a model where long‐run growth and industrial location are jointlyendogenous by introducing Romerian product innovation growth into Krugman'score–periphery model. We focus on stability, showing that growth is apowerful centripetal force, but that knowledge spillovers are a powerfulcentrifugal force. Integration policies that lower the cost of tradingideas are shown to encourage dispersion of economic activity while thosethat lower the cost of trading goods encourage agglomeration. Agglomerationis shown to be favourable to growth in both regions. The pro‐growth effectsmitigate the periphery's static welfare loss from agglomeration.
