The Long-Run Effect of Migration on Firms’ Trade: Evidence from China
利用19世纪广东移民潮形成的粤籍网络，研究发现该网络在数十年后仍能促进广东企业的出口、就业、工资和固定资产等指标。
We empirically assess the long-term effect of migration on the exporting behavior of firms in the migrants’ origin country. We focus on ethnic migrant networks formed as a result of a mass migration wave of ethnic Cantonese people from the Chinese province of Guangdong to the United States in the nineteenth century. Using firm-level data for Guangdong, we show that exposure to the Cantonese ethnic network has a positive effect on firms’ exports after several decades. We also find that networks have a positive effect on other firm outcomes, such as employment, wages, high-skilled workers, domestic capital, and fixed assets.
