ON THE IMPACT OF COMPETITION ON TRADE AND FIRM LOCATION
研究了贸易成本与竞争强度如何共同决定行业内贸易模式和企业跨国区位选择，发现贸易成本从高到低变化时，全球经济从自给自足演变为单向贸易再到双向贸易，且企业会从小国流向大国。
ABSTRACT We study how the level of trade costs and the intensity of competition interact to explain the nature and intensity of trade within a given industry and the location of firms across countries. As trade costs decrease from very high to very low values, the global economy moves from autarky to two‐way trade, through one‐way trade from the larger to the smaller region. By exploring the intensive and extensive margins of exports, we investigate how the intensity of trade reacts to the degree of competitiveness. Furthermore, when firms are free to change location, they flow from the small to the large country, and the larger country is always a net exported on the manufactured good. Firms located in the big country have a bigger size than those located in the small one. Under one‐way trade, the relocation of firms changes their attitude toward export.
