讲座摘要：We study how hospitals respond to diagnosis-related group (DRG) payment in terms of inpatient admissions. Exploiting the phased rollout of DRG payment across hospital tiers in a Chinese city, we find that the reform increased inpatient admissions by 6.8% while reducing expenditure per admission. Admission growth was concentrated among patients enrolled in the more highly reimbursed employee insurance program. We identify two margins behind this. Hospitals shortened stays and experienced more short-term readmissions to the index hospital, while readmissions to higher-tier hospitals declined. Hospitals also increased admissions following outpatient encounters without a statistically significant increase in overall outpatient volume, indicating adjustment at the outpatient-to-inpatient boundary. These findings show that case-based payment reshapes both how reimbursable cases are generated and how provider responses vary across insurance groups.
