【摘要】： 本文就影响经济增长因素的某一个方面即医疗卫生与经济增长的关系做了一些宏观分析。为了延长人们的寿命和提高人们的健康水平,一个社会必须要配置一定的经济资源来预防和治疗人们的疾病。而经济资源总是稀缺的,因此在配置资源时必须进行选择。医疗卫生的投入、人们健康水平的好坏对一个社会的经济增长就有至关重要的影响。本文第一部分简单介绍了经济增长的发展情况以及宏观经济研究的现代分析方法,提出本文的研究方向、目的及意义。本文第二部分推广了Uzawa-Lucas两部门经济增长模型,讨论了资源在医疗卫生部门和生产部门的最优配置问题,并就增长途径的稳定性给予了证明。本文第三部分建立了一个随机内生增长模型,将人们的健康水平作为影响人们福利的一个因素(仅次于其他消费)引入效用函数,讨论了在一定健康水平下政策参数对经济增长和社会福利的影响。发现在其他条件不变的情况下,若要提高经济增长率,应当降低私人健康投入;若要提高居民福利,则应当提高私人健康投资或提高税率。本文第四部分进一步讨论了第三部分的随机增长模型,但将健康存量作为状态变量引入到约束方程,进一步分析了健康水平在经济增长中的作用。得到这样的结论:消费者的风险厌恶系数偏小时,生产部门的产出关于医疗水平的弹性增大将会提高经济增长率,而医疗卫生部门的产出关于医疗水平的弹性增大却会降低经济增长率。
[Abstract]:This paper makes some macroscopic analysis on the relationship between medical and health care and economic growth, which is one of the factors affecting economic growth. In order to prolong people's life and improve their health, a society must allocate certain economic resources to prevent and treat people's diseases. Economic resources are always scarce, so we must choose when allocating them. The investment of health care and the quality of people's health have a vital impact on the economic growth of a society. The first part of this paper briefly introduces the development of economic growth and the modern analytical methods of macroeconomic research, and puts forward the research direction, purpose and significance of this paper. The second part of this paper generalizes the Uzawa-Lucas two-sector economic growth model, discusses the optimal allocation of resources in the health and production sectors, and proves the stability of the growth path. In the third part of this paper, a stochastic endogenous growth model is established, in which the health level of people is introduced into the utility function as a factor affecting people's welfare (second only to other consumption). The effects of policy parameters on economic growth and social welfare at a certain health level are discussed. It is found that in order to increase economic growth rate, private health investment should be reduced, and private health investment or tax rate should be raised if residents' welfare is to be increased. The fourth part of this paper further discusses the stochastic growth model of the third part, but introduces the health stock as a state variable to the constraint equation, and further analyzes the function of health level in economic growth. The conclusion is that the consumer's risk aversion is low, and the increased elasticity of the output of the production sector with respect to the level of health care will increase the growth rate of the economy. The increase in health sector output with respect to health care levels will reduce economic growth.
