讲座题目：From Gray Income to Health Gains: The Impact of Anti-Corruption Inspections in Chinese Hospitals

报告人: Xuan Zhang

内容摘要：We study how China’s anti-corruption campaign altered the behavior of healthcare providers and affected patient outcomes. Using 778,901 hospital admission records from obstetrics and gynecology departments from a central province between 2014 and 2017, we evaluate the effects of large-scale hospital inspections -- targeting physicians’ informal income and hospital quality monitoring -- through a staggered difference-in-differences design. The inspections led to higher aggregate admission costs, driven not by rising costs per case but by an expansion in the number of hospitalizations. Concurrently, the inspections improved both neonatal and maternal health outcomes. A back-of-the-envelope calculation indicates that the monetary value of these health gains exceeded the additional expenditures. Mechanism analyses suggest these results were driven by reduced pharmaceutical expenditures, increased diagnostic and surgical procedures, and more prenatal admissions, particularly among high-risk patients. Our findings demonstrate that the anti-corruption inspections enhanced healthcare access and generated substantial net health benefits, especially for vulnerable populations.
