Linking local services to global manufactures*
研究了全球冲击如何通过出口驱动的服务需求空间变化，从全球制造企业传导至地方服务提供商，发现出口每增加1%使服务企业销售额增长约0.08%，且该效应在20公里内显著，对大型和外资服务企业影响更大，并带动就业和生产率提升。
Abstract We assess how global shocks propagate from global manufacturing firms to local service providers through a spatial variation in export‐driven service demand. We show that a 1 percent increase in a localized measure of exporting increases sales of service firms by around 0.08 percent. We also show that this link is local as the effect fades away after just 20 km, that it is more pronounced with larger and foreign‐owned service firms, and that the impact extends beyond sales as it also increases employment as well as productivity in local service plants and it also make them less likely to move.
