Using data from the American Medical Association's Physician Masterfiles (1963-80) and the GINI index of resource concentration as a global measure of changes in the pattern of locational choice, the expectation of a more uniform distribution of physicians is shown to have been met for all major categories of physicians except General Practitioners. Increases in the supply of Surgical Specialists, Medical Specialists, and Other Specialists were accompanied by increases in the index of dispersion across counties of 23.1 per cent, 17.9 per cent and 21 per cent, respectively. By 1980, Surgical Specialists were the most uniformly distributed of all physician groups. The distributional implications of location theory for physicians are addressed and evidence relevant to evaluating this economic theory of locational choice is presented.
利用美国医学协会医师主文件（1963 - 1980年）中的数据以及资源集中度的基尼指数作为区位选择模式变化的总体衡量指标，研究表明，除全科医生外，所有主要类别的医生均实现了分布更均匀的预期。外科专科医生、内科专科医生和其他专科医生的供给增加，同时，各县之间的离散指数分别上升了23.1%、17.9%和21%。到1980年，外科专科医生是所有医师群体中分布最为均匀的。文中探讨了区位理论对医生的分布影响，并给出了与评估这一区位选择经济理论相关的证据。
