Abstract:
Objective To investigate urban residents’ willingness-to-pay (WTP) for ambient air pollution control to avoid the adverse health effects in Qingdao, China. Methods A contingent valuation method (CVM) was employed and a sample of 1 050 residents was randomly chosen, 21st to 27th January, 2007. A series of hypothetical, open-ended scenario questions were designed to elicit the respondents’ WTP with face-to-face interviews. A Probit model on the probability of a positive WTP and a stepwise regression model were established to find the relationship between endogenous variables and WTP. Results 1 008 valid questionnaires were obtained. 73.9% respondents believe that air pollution had adverse effects on health. 54.6% respondents cost 100 to 500 Chinese Yuan (CNY) on treatment of respiratory diseases for their whole family. 94.2% respondents were able to express positive WTP and the median WTP was 600 Chinese Yuan (CNY) per household per year. Conclusion Urban residents’ aggregate WTP accounted for 1.25% of annual household income and 11.9% of government investments for air pollution control in 2005. Residents’ age, job and household income variables had significant influence on the probability of a positive WTP. Residents’ household income, education level, expenditure on treatment of respiratory diseases and age significantly influence WTP value.
