Health care financing arrangements not only have strong implications for income distribution, but also affect health care utilization. Therefore, a comparison of the equity in health care utilization for those health systems with different financing arrangements has important policy implications for health care policymakers. The concentration index (CI) and the horizontal inequity index (HI) are commonly used to measure inequality and inequity in health care utilization. In this paper, we propose simple methods to decompose the difference between two CIs and two HIs into two factors: one factor reflects the difference between the means, and the other factor reflects the difference between the distributions. The proposed decomposition method might be useful since the means are likely to be caused by factors that do not constitute unfair inequalities (inequities). We also present two empirical applications of the decomposition methods for the purpose of illustration.
医疗保健融资安排不仅对收入分配有重大影响，还会影响医疗保健的利用情况。因此，对具有不同融资安排的卫生系统在医疗保健利用方面的公平性进行比较，对医疗保健政策制定者具有重要的政策意义。集中度指数（CI）和横向不公平指数（HI）通常用于衡量医疗保健利用中的不平等和不公平。在本文中，我们提出了简单的方法，将两个CI和两个HI之间的差异分解为两个因素：一个因素反映均值之间的差异，另一个因素反映分布之间的差异。所提出的分解方法可能会很有用，因为均值可能是由不构成不公平不平等（不公平）的因素引起的。为了说明，我们还给出了分解方法的两个实证应用。
