演讲题目：Information Provision and Streamlined Medical Service: Evidence from a Mobile Appointment App
演讲嘉宾：Yang Nan，National University of Singapore Business School
We examine a mobile outpatient appointment app---a light-weight information technology innovation---launched by Chinese hospitals. The objective is to assess the effect of information provision and a streamlined appointment process on hospital operations and the alignment of healthcare supply and demand. Using a longitudinal dataset on hospital operation and a difference-in-differences model, we document that the app increases completed hospital consultations by 9.5%, by boosting registrations by 4.8% and reducing appointment cancellations by 3.4%. The app improves queuing efficiency in overcrowded hospitals and draws demand for underutilized ones. It results in a better match between patient demand and hospital service by directing patients to the hospital and department more suitable to one's medical conditions and to less busy days. Subsequent app launches shorten average waiting time for booked appointments.
