Analyzing the Healthcare Expenditure of National Health Insurance: A HLM Model Construction on the National Health Insurance Database

The current National health insurance in Taiwan is a system widely praised by other countries, but the rising healthcare expenditure has been a serious financial issue in recent years. Many scholars have adopted the National Health Insurance Research Database (NHIRD) for all sorts of research studies. However, few have conducted research from the perspective of multiple-level stakeholders, which remains to be a worth exploring research direction. This research addressed the above issue by constructing a Hierarchical linear modeling (HLM) based on the available data in NHIRD in order to identify key factors influencing health spending. A future work is to conduct an empirical study to validate the HLM model, which can be also good reference for future insightful research on multiple-stakeholder perspective.
