Willingness to pay for air quality improvement and its influencing factors of residents in Changsha and Shijiazhuang Cities based on the stochastic payment card value elicitation technique of CVM
Previous studies on evaluating individuals'willingness to pay rarely considered the complexity of the real environment for decision-making and the limitations of respondents'cognition and information acquis-ition.Therefore,most of them have not yet reflected the latest research results in the field of environmental and economic value evaluation.In particular,there is a lack of uncertainty consideration of respondents'prefer-ences and result in a large error for the evaluation of WTP.Based on random value theory,taking Changsha City,Hunan Province and Shijiazhuang City,Hebei Province as examples,this paper empirically analyzes res-idents'WTP for air quality improvement and its influencing factors by using SPC value elicitation technique of CVM.The aim is to provide insights and references for the improvement of CVM research and the benefit-cost analysis of atmospheric environmental governance policies in China.The results reveal that:1)Residents in the two cities have significantly different attitudes towards WTP for air quality improvement.The proportion of residents in Shijiazhuang who hold positive attitudes is significantly higher than that in Changsha.More than 20％of the residents in both cities stated"Definitely Yes"for contributing money,while 7％-10％expressed"Definitely No".The reasons for unwilling to pay are closely related to their role orientation,payment ability and institutional trust in environmental governance.2)The average WTP of residents in Shijiazhuang is signi-ficantly higher than that in Changsha.The sample average value for the mean of WTP in Changsha is 97.87 yuan/month,the sample average value of standard deviation is 128.69,and Shijiazhuang is 108.24 yuan/month and 142.64,respectively.3)The most important micro-factor affecting residents'WTP is education level,which reflects the important role of information factors in personal and family characteristics.Secondly,it is the influence of the trust and satisfaction with the government,which reflects the importance of the relation-ship between the government and the people on decision-making of residents'behaviors.Thirdly,it is the influ-ence of income level and its expected changes,which reflects the important role of economic factors.Finally,it is the influence of risk preference,which reflects the importance of personal attitude towards environmental risks.The main macro factors are residential cities and regions,followed by per capita GDP in each region.It shows that residents'WTP is different between the south and north area for the large spatial scale and between the city center and the suburbs for the small spatial scale.However,the level of payment is not necessarily matched with the level of urban economic development.It may also be affected by the comprehensive influ-ence of residents'cognition,attitude,and other factors.Based on the analysis,this paper put forward some re-lated policies and suggestions for improving CVM implementation,promoting the effective evaluation of the effect of air quality improvement as well as public participation in environmental governance.
