In this paper, a survey of rural Tianjin residents' willingness-to-pay for health improvement was reported on, and the MBDC(multiple bounded discrete choice) model was adopted to study the respondents' willingness-to-pay to prevent respiratory illnesses. The results showed that the willingness-to-pay for health improvement was affected by respondents' health condition, work situation and environmental awareness, but not by personal habits, such as smoking. If person's willingness-to-pay to avoid respiratory diseases can be considered equal to the cost to personal health caused by air pollution, the total cost will reach 538×10 6 RMB Yuan(RMB, equal to 65 million USD) per year.展开更多

The WTP data are analyzed with region-, age- and gender-specific cancer morbidity and mortality risk statistics; an upper and lower bound of the Value of a Statistical Life （VSL） are then estimated. The estimated VSL is between 481 and 814 thousand yuan （or 58 and 98 thousand US dollars） at 2000 constant prices, which is compatible with the results of previous studies.展开更多
