A Note on Hospital Profitability in Taiwan

This study adopts Random Forest Regression to analyze key factors influencing hospital profitability under the National Health Insurance system.Using financial data from 2015 to 2022 (1,560 records), we identify the top five influential factors: Net Non-Operating Income, Medical Revenue, Medical Costs, Medical Operating Expenses, and Patient-to-Nurse Ratio.Among these, Net Non-Operating Income and Medical Revenue contribute the most to the model's predictive accuracy, together accounting for over 92% of the total feature importance.The results further reveal that the relationships between these factors and hospital profitability are complex and nonlinear.
