Political hierarchy spillovers: Evidence from China

This paper explores the impact of the political hierarchies of cities in China from different perspectives. First, we examine the economic disparities between prefectural cities and municipalities. Furthermore, this paper draws upon a quasi- experiment to analyze the impact of upgrading Chongqing to a municipality in 1997 using the synthetic control method. The city-upgrading policy significantly increased Chongqing's gross domestic product (GDP) in the following 4 years. Finally, we find that the policy increased GDP in treated cities within 1200 km of Chongqing by about 10%-13% relative to the control cities.
