Abstract
Air pollutions in some cities of developing countries are becoming serious, and it is desired to evaluate the value of a good atmosphere for the assessment of the effect of policies and international cooperation. We consider the evaluation of impacts by damages on human health by air pollution in monetary unit. A social survey was launched in Beijing for the economic valuation of human health damage caused by air pollution. Seven hundred subjects were sampled by multistage area sampling. Subjects were sampled from six districts in the central of Beijing. The main part of the survey is based on contingent valuation method and for evaluation of willingness to pay for a nebulizer to avoid health damages. Questions based on the method of conjoint analysis have been asked for the analysis of trade-off between convenience, environment and monetary burden. The answers were analyzed statistically and factors that affect the answers have been analyzed. Annual household income was the most important factor, but there were other factors that affected the willingness to pay.
