摘要

摘要本文对2011年至2017年南非医疗保险市场的效率、生产力和规模经济回报率进行了全面评估。经济学理论认为,市场中的竞争水平和整体效率水平之间存在着关系。在大多数情况下,市场效率将与现有市场竞争水平呈正相关。这对南非的私人医疗计划行业有直接影响,根据竞争委员会的健康市场调查,该行业类似于一个缺乏竞争力的市场结构。在进行研究时采用了数据包络分析,以估计开放和限制医疗计划的效率得分和规模回报率。Malmquist指数用于评估医疗计划生产率增长,而截断自举回归和逻辑回归技术用于确定效率的决定因素和在恒定规模回报率下运营的概率。实证结果表明,开放医疗计划往往比限制性医疗计划更有效。更重要的是,经验证据表明,开放和限制医疗计划的效率都有提高的空间。

Efficiency, productivity and returns to scale economies in South Africa’s healthcare insurance market
Abstract This article sets out a comprehensive assessment of efficiency, productivity and returns to scale economies in South Africa’s Healthcare Insurance market for the period 2011 to 2017. Economic theory suggests that there exists a relationship between the level of competition and the overall level of efficiencies within a market. For the most part, market efficiencies will be positively correlated with the level of existing market competition. This has direct implications to South Africa’s private medical scheme industry, which according to the Competition Commission’s Health Market Inquiry resembles an uncompetitive market structure. Data Envelopment Analysis was employed while conducting the study in order to estimate efficiency scores and returns to scale for both open and restricted medical schemes. The Malmquist index was employed to assess medical scheme productivity growth whereas a truncated bootstrapped regression and a logistic regression technique was employed to identify the determinants of efficiency and the probability of operating under constant returns to scale. The empirical results reveal that open medical schemes tend to be more efficient than restricted medical schemes. More so, the empirical evidence reveals that there is room for improvement of efficiencies for both open and restricted medical schemes.
