Results: Our research findings were as follows: (1) If short and mid-term physician manpower policies are fixed, certain supporting plans will be needed. (2) If short and mid-term physician manpower policies are not constant, the manpower problem shall be adjusted with solutions. (3) If short-and mid-term physician manpower policies adopt to an open system, there will be an oversupply of physicians in the long run. Conclusions: Finally, we expect that Taiwan’s physician manpower policies can be improved.
