摘要
Along with the reduction in transportation costs in the last two centuries, institutional trade barriers have become increasingly important obstacles to further market integration. This paper examines the impact of a policy reform in China that removed inter-regional administrative trade barriers by incorporating counties into prefectures with a larger market. Using a difference-in-differences approach, we compare incorporated counties, both before and after the reform, to two novel control groups: counties that applied for incorporation but failed and counties that were incorporated several years later. We find that the reform immediately and persistently increased the economic growth of incorporated counties. Several sources of evidence suggest that treated counties experienced relatively rapid growth because they became more integrated into the domestic market. First, using an indirect measure of protection, we find that the reform significantly reduced local protectionism between incorporated counties and their corresponding prefectures. Second, market shares of more productive sectors increased in treated counties following the re-form. Third, firms producing tradable goods rapidly entered treated counties. Finally, less profitable firms in treated counties were more likely to exit.
