One of the objectives of managed care organizations (MCOs) has been to reduce the rate of growth of health care expenditures, including that of physician fees. Yet, due to a lack of data, no one has been able to determine whether MCOs have been successful in encouraging the growth of price competition in the market for physician services in order to slow the growth in physician fees. This study uses a unique, national-level data set to determine what factors influenced the physician fees that MCOs negotiated during the 1990-92 period. The most influential characteristics were physician supply and managed care penetration, which suggest that the introduction of competition into the health care market was an effective force in reducing physician fees.
管理式医疗组织（MCOs）的目标之一是降低医疗保健支出的增长率，包括医生费用的增长率。然而，由于缺乏数据，没有人能够确定MCOs是否成功地促进了医生服务市场价格竞争的加剧，从而减缓了医生费用的增长。本研究使用了一个独特的国家级数据集，以确定在1990 - 92年期间影响MCOs谈判的医生费用的因素。最具影响力的特征是医生供给和管理式医疗的渗透率，这表明将竞争引入医疗保健市场是降低医生费用的有效力量。
