政府最优卫生健康支出研究

Research on Optimal Government Health Expenditure

目的:分析政府增加卫生健康支出的条件以及卫生健康支出在总税收中的最优占比。方法:通过构建世代交叠模型(OLG),引入了卫生健康支出对长寿风险的影响,从而建立了卫生健康支出与经济增长之间的关系;使用MATLAB软件进行数值模拟,测试各参数变动对经济的影响。结果:当经济环境满足阈值条件时,存在最优卫生健康占比,以助力人均最大化。结论:劳动产出弹性系数、资本产出弹性系数越大,最优卫生健康支出比例越大;效用贴现因子越大,最优卫生健康支出比例越小。

Objective:To analyze the conditions for government to increase health expenditure and the optimal proportion of health expenditure in total tax revenue.Methods:The influence of health expenditure on longevity risk was introduced by constructing Over Lapping Generation models(OLG models),and the relationship between health expenditure and economic growth was established.MATLAB was used to conduct numerical simulation to test the impact of parameter changes on the economy.Result:When the economic environment meets the threshold condit ions,there is a proportion of health expenditure that leads to the highest output per capita.Conclusion:The greater the elasticity coffcient of labor output and eapital output,the greater the proportion of optimal health expenditure;the larger the utility discount factor,the smaller the proportion of optimal health expenditure.
