Abstract:
This paper delves into the impact of within-city administrative border adjustments on individual firm productivity and local economic development. Employing a unique quasi-natural experiment conducted in China since the 1990s, our empirical analysis reveals that district border adjustments (DBAs) have a significant positive effect on the TFP of manufacturing firms in the adjusted districts. The firms situated in the border towns of the districts reap most benefits. Further investigation into the mechanism indicates that DBAs enhance firms’ productivity by 1) internalizing the positive externalities generated by agglomeration economies of industry clusters, 2) removing extra administrative costs for firms situated in the border towns, and 3) helping alleviate the spatial constraints faced by high density core districts. These adjustments ultimately lead to enhanced industry specialization and more efficient capital allocation at the district level. Our study also shows that DBAs have a significantly positive impact on the overall economic development of border towns, as evidenced by increased intensity of nightlights.
