【摘要】：以往对于环境税的双重红利的分析大都建立在消费者的效用函数可分的基础上,这说明消费者在休闲娱乐和商品之间的边际替代率并不受环境质量变化的影响,然而商品价格变化不仅对劳动力供给产生影响,而且对环境质量和娱乐、对劳动力的供给也有一定的影响。文章不仅假设效用函数是不可分的,同时在效用函数直接引入与环境质量和娱乐相关的健康水平,并且引入了一个全新的、重要的假设即休闲娱乐有益于健康,进一步得出环境税的征收一方面改善了环境质量,提高了居民的健康水平;另一方面提高了产品价格,使得居民收入相对减少,但由此相应增加锻炼身体的时间,进而提高健康水平。总之,随着健康水平的提高,劳动力的供给会逐渐提高,至少弥补了部分由于产品价格提高带来的短期内劳动力的减少,因此从长期看,环境税的这种健康效用确保了双重红利的存在。
[Abstract]:In the past, the analysis of double dividend of environmental tax was mostly based on the divisible utility function of consumers, which showed that the marginal substitution rate of consumers between leisure, entertainment and goods was not affected by the change of environmental quality. However, the change of commodity price not only affects the supply of labor, but also affects the quality of environment and entertainment, as well as the supply of labor. The paper not only assumes that utility function is inseparable, but also introduces directly the health level related to environmental quality and entertainment, and introduces a new and important hypothesis that leisure and recreation are beneficial to health. On the one hand, the collection of environmental tax has improved the quality of the environment and raised the health level of the residents; on the other hand, it has raised the price of products and made the income of the residents relatively low, but this has resulted in a corresponding increase in the time spent exercising. And then raise the level of health. In short, as the level of health improves, the supply of labor will gradually increase, at least partly to make up for the reduction in the short-term labor force due to the increase in product prices. Therefore, in the long run, This health effect of an environmental tax ensures the existence of a double dividend.
