Abstract

Background: The COVID-19 pandemic has brought significant health shocks worldwide, along with a certain burden on healthcare systems. China's healthcare security system has been continuously improved and has essentially achieved universal coverage. Moreover, the health impact of COVID-19 on the Chinese population is diminishing, and the trend of consumption upgrading is becoming more pronounced.

Methods: Based on the Ramsey-Cass-Koopmans model, this study constructs a theoretical model of "health shocks-consumption upgrading" to deduce the impact of health shocks on consumption upgrading. We examine the results of the theoretical model using provincial panel data from China spanning from 2002 to 2019 and employing the system GMM estimation method. Furthermore, based on a moderation effect model, we explore the mechanism of basic medical insurance systems in this model.

Results: The theoretical model deduces that health shocks lead to a decline in consumption upgrading, which is empirically confirmed. Additionally, the results of moderation effect analysis demonstrate that basic medical insurance systems play a positive moderating role in the "health shocks-consumption upgrading" model. Among the basic medical insurance systems, the New Rural Cooperative Medical Scheme (NRCMS) primarily acts as a positive moderator.

Conclusion: Health shocks lead to consumption downgrading, while basic medical insurance systems help to diversify medical risks, alleviate health shocks, reduce precautionary savings, and thereby promote consumption upgrading.

医疗保险在“健康冲击-消费升级”模型中的作用分析：来自中国的证据。

背景：2019冠状病毒病大流行在全球范围内带来了重大的健康冲击，并给卫生保健系统带来了一定负担。中国医疗保障体系不断完善，基本实现全民覆盖。此外，新冠肺炎疫情对中国民众健康的影响正在减弱，消费升级趋势更加明显。方法：基于Ramsey-Cass-Koopmans模型，构建“健康冲击-消费升级”的理论模型，推导健康冲击对消费升级的影响。我们使用中国2002 - 2019年的省级面板数据，采用系统GMM估计方法对理论模型的结果进行了检验。在此基础上，建立了一个调节效应模型，探讨了基本医疗保险制度在此模型中的作用机制。结果：理论模型推导出健康冲击导致消费升级下降，并得到实证证实。此外，调节效应分析结果表明，基本医疗保险制度对“健康冲击-消费升级”模型具有正向调节作用。在基本医疗保险制度中，新型农村合作医疗主要起到积极调节作用。结论：健康冲击导致消费降级，而基本医疗保险制度有助于分散医疗风险，缓解健康冲击，减少预防性储蓄，从而促进消费升级。
