In the framework of endogenous growth, this paper assumes that health is produced by combining public health expenditure, public infrastructure service and environment quality in the form of Cobb Douglas technology. We examine the optimal growth of balanced growth path in which the positive effect of public awareness of health affects economic growth through changes of government expenditure on health and environment. The result shows that: environment affects economic growth through health, and welfare maximizing government should increase environment protection expenditure to improve environmental quality; the more the representative citizens care about the health, the more growth enhancing policies a welfare maximizing government should choose; in turn, this improves health and environment as well as stimulates economic growth. With the data of 29 provinces from 1997 to 2013, we analyze the hypothesis of health production function and the existence of mechanism that environment affects economic growth through health.
