Producer Services, Economic Geography, and Services Tradability
研究了生产者服务如何影响经济地理模型的结果，发现服务关联促进经济活动集中，但完全集中取决于服务贸易的成本和模式，多区域世界中生产者服务可能导致区域专业化。
We investigate how the incorporation of producer services linkages affects the outcome of an economic geography model. We specify the production of manufactures such that a variety of producer services is needed to transform tradable unfinished goods into final consumption goods. We find that service linkages promote the concentration of economic activity in a single region, but whether full concentration is achieved depends on the costs and mode of services trade. Applying the model to a multiregion world shows that incorporating producer services may also give rise to regions that specialize in different economic activities.
