GLOBALIZATION AND THE EVOLUTION OF THE SUPPLY CHAIN: WHO GAINS AND WHO LOSES?*
研究贸易成本下降和通信成本下降两种全球化形式的影响。当两地非熟练工人工资相近时，成本下降导致工厂向总部所在核心区集聚；当工资差距显著时，整合过程会引发工厂向边缘区迁移，且若由通信成本下降驱动，核心区工人福利下降而边缘区上升。
This article focuses on two distinct facets of globalization: decrease in the trade costs of goods and the decline of communication costs between headquarters and production facilities. When the unskilled have about the same wage in two regions, decrease of these costs fosters the agglomeration of plants in the core accommodating headquarters. When the wage gap is significant, process of integration eventually triggers the relocation of plants into the periphery. When this process of relocation is driven by falling communication costs, the welfare of all workers in the core falls whereas that in the periphery rises.
