目的:随着经济的高速发展,消费者收入普遍得到增长,但是其健康状况并没有得到相应改善,因此,研究消费者如何在消费和健康投资之间进行理性决策具有重要的现实意义。方法:根据最优控制模型,分析了不确定条件下的消费者最优的健康投资路径。结果:从外部环境来看,一旦降低健康投资的成本和市场利率,则能够增加消费者的健康投资水平;从消费者自身来看,如果消费者的初始健康水平越高,则越有动力进行健康投资;同时,如果消费者健康退化程度越快,对未来的预期越高,也会提高其健康投资水平。结论:为了提高全民的健康水平,提高消费者健康投资的动力,一方面需要利用补贴进行外部刺激,另一方面也要通过健康教育等提高消费者的健康认知。
OBJECTIVE: With the rapid economic development, the general increase of consumer income, but its health status has not been correspondingly improved. Therefore, it is of great practical significance to study how consumers make rational decisions on consumption and health investment. Methods: According to the optimal control model, the optimal health investment path of consumers under uncertainty is analyzed. Results: From the perspective of the external environment, once the cost of health investment is reduced and the market interest rate is lowered, the health investment level of consumers can be increased. From the point of view of consumers themselves, the higher the initial health level of consumers, the more motivated Health investment; the same time, if the consumer health degradation faster, the higher the expectations of the future, will also increase their health investment level. Conclusion: In order to improve the health of all people and increase the motivation of consumers ’health investment, on the one hand they need to use subsidies for external stimulus, on the other hand, health education should be used to improve consumers’ health awareness.
