This paper tests the null hypothesis of no horizontal inequity in delivery of health care by use of count data hurdle models and Swedish micro data. It differs from most earlier work in three principal ways: First, the tests are carried out separately for physician and hospital care; second, the tests are carried out separately for the probability of seeking care and the amount of care received (given any use); and third, the tests are based on a model that includes several socioeconomic variables, e.g. income, education and size of community of residence. The paper rejects the hypothesis of no inequity because socioeconomic factors also have significant effects on utilization, e.g. income and size of community of residence. Size of community of residence has a positive significant effect on the frequency of physician visits but not on the probability of visiting a physician.
本文运用计数数据障碍模型和瑞典微观数据，检验了医疗保健服务中不存在横向不公平的原假设。它在三个主要方面不同于大多数早期研究：第一，分别对医生诊疗和医院护理进行检验；第二，分别对寻求医疗服务的概率和所接受的医疗服务量（给定任何使用情况）进行检验；第三，检验基于一个包含多个社会经济变量的模型，例如收入、教育程度和居住社区规模。本文拒绝了不存在不公平的假设，因为社会经济因素也对医疗服务利用有显著影响，例如收入和居住社区规模。居住社区规模对看医生的频率有显著的正向影响，但对看医生的概率没有影响。
