Platform advantages or "policy trap" for neighbors? Export effects of establishing free trade zone in China: A quasi-natural experiment

As the important regional policy arrangements for China to implement a new round of opening-up strategy, the free trade zone (FTZ) policy have significant impacts on export trade. Based on the quasi-natural experiment of China's establishment of FTZs, the article evaluates the impact of the FTZs on enterprises' exports by using export data from Chinese Customs database and statistics of prefecture-level cities in China from 2007 to 2018. The analyses found that the FTZs has significantly promoted local exports. The FTZs has negative spatial externalities on export activities, which reduces the export performance of neighboring cities. The export effects of FTZs present continuous and dynamic characteristics. There is heterogeneity in the marginal impact of FTZs in different locations on the exports of enterprise. These findings provide empirical evidence for a more comprehensive understanding of the impact of the establishment of FTZs on enterprises' exports in the spatial dimension.
