Urban Administrative Restructuring and Gender Gap in the Labor Market: Evidence From China's City‐County Merger Reform
研究中国撤县设区改革如何影响劳动力市场的性别差距，发现改革显著扩大了性别工资差距，主要受移民流入、制造业扩张、交通改善和房价上涨等渠道驱动，且对农村、低学历及发达县域的女性影响更大。
ABSTRACT As a major form of urban administrative restructuring in China, city‐county mergers dismantle boundaries between municipal districts and surrounding counties, creating more integrated local labor markets. Using longitudinal data from the China Household Finance Survey and a difference‐in‐differences framework, we examine how this restructuring affects gender disparities in labor market outcomes. We find that the reform significantly widens the gender wage gap. Mechanism analysis shows that this gap is driven by several channels, including increased labor competition from migrant inflows, the expansion of manufacturing activity, improvements in transportation infrastructure, and rising housing values. The effects are highly heterogeneous: rural and less‐educated women, as well as women in more developed counties, experience the largest losses relative to men.
