In this paper, structural equations for the supply of and the demand for general practitioners' services are derived. Two variants of the model, based on alternative specifications of the role of health insurance, are tested, using data drawn from the American Medical Association's Eighth Periodic Survey of Physicians (PSP8). While results of the estimation require the rejection of the hypothesis that the market for general practitioners' service is perfectly competitive, the elasticities of demand implied are quite high. Estimates of the supply relationships support the presence of "backward bending" supplies of physicians' services, but this finding should be interpreted cautiously.
本文推导了全科医生服务供给和需求的结构方程。基于医疗保险作用的不同设定，对该模型的两个变体进行了检验，使用的数据来自美国医学协会的第八次医生定期调查（PSP8）。虽然估计结果需要拒绝全科医生服务市场完全竞争的假设，但所隐含的需求弹性相当高。对供给关系的估计支持了医生服务存在“向后弯曲”供给的观点，但这一发现应谨慎解读。
