中国经济历经30多年高速增长，但环境污染问题也日趋严峻，不断成为社会和学术关注的热点问题。与现有强调经济活动和政策如何影响环境质量的研究不同，本课题将从环境污染如何通过健康这个渠道影响家庭微观决策的角度，来分析环境污染对经济增长和社会福利的影响。我们首先就以下三个递进的研究内容展开实证研究：环境污染如何影响健康、健康如何影响居民家庭医疗支出、家庭医疗支出又如何影响家庭教育投资和储蓄。然后，基于实证研究结论，我们计划构建一个包含污染、健康、教育投资的新古典经济增长模型，分析环境污染对经济增长和社会福利的影响。最后，基于理论模型，我们进一步讨论如何设计环境、教育和健康政策的最优组合来实现社会福利最大化。

China has experienced more than three decades of rapid growth, but the environmental pollution deterioates over time, which has becomes a serious concern of the society and academy. Different from existing studies that focus on how economic activities and policy affect the environmental quality, this project studies how pollution affects the economic growth and social welfare, via the channel of how pollution affects health and family decisions. We first implement three empirical studies: how environmental pollution affects health, how health affects the family medical expenditure and how the medical expenditure affects the family education investment and savings. Then based on the empirical results, we in further construct a new-classical economic growth model incorporating pollution, health and education investment to study how environmental pollution affects the economic growth and social welfare. Finally based on the theory model, we study how to design optimal combination of environmental policy, education policy and health policy to maximize the social welfare.
