本文設計一個納入SIS傳染病機制與環境污染的內生成長模型，凸顯環境污染是疾病傳播管道的事實，據此指出經濟社會存兩種均衡。在無疾病均衡下，政府的國民健康政策與污染防治政策均不會影響均衡成長率；然而，在流行病均衡下，污染排放係數降低或污染減量效率提高均可以增加經濟社會的勞動力並刺激經濟成長表現。另外，健康支出補貼政策與政府污染防治政策亦會提高流行病均衡下的勞動力與經濟成長率。

Pollution not just affects health conditions but also affects the labor supply decision. It shortens working lives and increases the number of days lost to illness. This paper incorporates the SIS (susceptible-infected-susceptible) model into an environmental endogenous growth model, and uses it to examine the impact of pollution on the public health and economic growth. We find that a decrease in the pollution will increase the labor force and hence stimulate economic growth. Furthermore, we show that a health expenditure subsidy or a public abatement expenditure will increase the labor supply and economic growth.
