【摘要】：本文着重考察公共健康支出对私人健康投资和储蓄的影响。其分析建立在一个完全预见下具有同质性消费者和厂商的两期OLG模型基础上,其中公共和私人的健康投资发生在第一期,第一期健康人力资本的形成取决于公共和私人健康投资的总量,两者具有完全替代性;而且公共健康投资具有一定的外部性,能影响第二期的健康人力资本存量。分析结果表明:(1)资本产出份额越大,健康人力资本的折旧速度越慢,经济体的稳态值越高。而且,外生的技术参数和税率水平的变化具有经济增长的水平效应。(2)经济发展存在着门槛限制。在经济发展的低水平阶段,储蓄中物质资本所占份额相对越大,或者健康投资中公共投资所占比重小都不利于经济体突破门槛条件。而在较高发展阶段,沿平衡增长路径,政府应适当减少对公共健康投资的融资,释放经济体中私人部门的投资活力,以实现稳态时更高的人均资本存量水平和产出水平。(3)在经济发展的任何阶段,促进技术水平和劳动生产率的提高都有利于经济发展。
[Abstract]:This paper focuses on the impact of public health expenditure on private health investment and savings. The analysis is based on a two-period OLG model with homogeneous consumers and firms under complete foresight. The public and private health investment occurs in the first phase, the formation of the first phase of health human capital depends on the total amount of public and private health investment, both of which are completely substituted, and the public health investment has a certain degree of externality. The results show that the larger the share of capital output, the slower the depreciation rate of healthy human capital and the higher the steady state value of the economy. The changes of exogenous technical parameters and tax rates have the horizontal effect of economic growth. (2) there are threshold restrictions on economic development. The lower the level of economic development, the larger the share of material capital in savings. Or the small proportion of public investment in health investment is not conducive to the economy breaking through the threshold conditions. However, at a higher stage of development, along the path of balanced growth, the government should appropriately reduce the financing of public health investment. Releasing private sector investment in an economy to achieve a higher level of per capita capital stock and output at a steady state) will be beneficial to economic development at any stage of economic development.
