英文文献：The impact of private health insurers on the quality of Russian regional health systems-私营健康保险公司对俄罗斯区域卫生系统质量的影响

英文文献摘要：
The 1991 law ‘On health insurance for the citizens of the Russian Federation’ established that social health insurance is to be offered by multiple private insurance companies. The paper is the first econometric analysis measuring the effect of private health insurers on quality related outcomes of social health insurance (SHI) systems in Russian regions. The baseline model introduces regional SHI system as a binary variable with unity value corresponding to the presence of private health insurers as the only agents at the SHI market. The extended model captures endogeneity by employing an instrumental variable approach. The non-parametric model uses kernel regressions. The results of parametric and kernel regressions reveal that the presence of private insurers is a significant determinant of infant and under-five mortality. The positive impact of private insurers is explained by regional institutional reforms. The methods of provider reimbursement are related to infant and under-five mortality, which offers suggestive evidence for enabling insurer competition through selective contracting with health care providers.
1991年《俄罗斯联邦公民健康保险法》规定，社会健康保险由多家私营保险公司提供。本文是首次计量经济学分析，衡量私营医疗保险公司对俄罗斯地区社会医疗保险体系质量相关结果的影响。基线模型将区域医疗保险系统作为二元变量引入，其单位值对应于作为医疗保险市场唯一代理人的私营医疗保险公司。扩展的模型通过使用工具变量方法捕获内生性。非参数模型使用核回归。参数回归和核回归的结果表明，私营保险公司的存在是婴儿和五岁以下儿童死亡率的一个重要决定因素。私营保险公司的积极影响可以用区域制度改革来解释。提供者的补偿方法与婴儿和五岁以下儿童的死亡率有关，这为保险公司通过有选择地与保健提供者签订合同而实现竞争提供了暗示证据。
