英文题目：A General-Purpose Technology at work: The Corliss steam engine in the late-nineteenth-century United States摘要：蒸汽机工业革命的标志和“通用技术”的主要例子对增长的贡献仍不清楚。
本文探讨了科利斯发动机中体现的蒸汽动力设计改进在19世纪末美国经济增长中所起的作用。
使用有关Corliss引擎和水轮位置的详细数据和两阶段估计策略，我们表明，Corliss引擎的部署是该行业大规模迁移到大型城市中心的催化剂，从而推动了集聚经济和人口进一步增长。
Abstract:The contribution to growth from the steam engine-Industrial Revolution icon and prime example of a "General Purpose Technology"-has remained unclear. This article examines the role that a particular design improvement in steam power, embodied in the Corliss engine, played in the growth of the U.S. economy in the late nineteenth century. Using detailed data on the location of Corliss engines and water-wheels and a two-stage estimation strategy, we show that the deployment of Corliss engines served as a catalyst for the industry's massive relocation into large urban centers, thus fueling agglomeration economies and further population growth.
