1. Inadequate insurance coverage: If the health insurance coverage in a region or a country is low, many people need to pay out-of-pocket when they seek medical treatment, resulting in a low overall healthcare service revenue.
2. Insufficient medical resources: If medical resources (e.g., doctors, medical equipment, medical institutions, etc.) cannot meet the demand, patients may choose to seek alternative means or delay medical treatment, resulting in less revenue from medical services.
3. Limitations on healthcare costs: Certain regions or countries may set caps on healthcare costs to ensure that the burden is affordable for patients. This may result in some limitations on healthcare service revenue.
4. Patient choice: Some patients may be accustomed to low-cost care or may choose informal care, which may also result in lower revenues for formal care.
5. Inadequate education and health awareness: If the residents of a region or country have a low awareness of health education and disease prevention, this may lead to a lower demand for healthcare services, which in turn may lead to a lower income from healthcare services.
The above are just some of the possible reasons, and the specifics need to be analyzed in depth in relation to the healthcare system and policies of the specific region or country.
