【摘要】：运用意愿调查法调查了北京市和南昌市居民对降低PM2.5年均浓度的支付意愿。结果表明:北京居民愿意为降低PM2.5年均浓度的30%、45%和60%而平均每月支付71.60元、85.66元和94.31元;南昌居民仅愿意为降低30%和50%而平均每月支付31.43元和52.47元。运用Logit逐步回归分析表明:北京居民对PM2.5相关后果的判断、南昌居民对PM2.5可控性的判断分别显著影响是否愿意支付。半对数多元逐步回归表明:影响北京居民支付意愿大小的因素较多,PM2.5对社会的影响程度、风险发生可能性、风险持续时间和风险可控性等均表现出显著影响;而显著影响南昌居民支付意愿大小的因素仅有社会的影响程度、平等性与年龄3项。
[Abstract]:The willingness to pay for the reduction of PM2.5 annual concentration in Beijing and Nanchang was investigated by means of willingness survey. The results show that Beijing residents are willing to pay an average of 71.60 yuan, 85.66 yuan and 94.31 yuan per month for reducing the average annual concentration of PM2.5 by 30% and 60%, while Nanchang residents are willing to pay an average of 31.43 yuan and 52.47 yuan per month for the purpose of reducing PM2.5 concentration by 30% and 50%. Logit stepwise regression analysis showed that Beijing residents' judgment on PM2.5 related consequences and Nanchang residents' judgment on PM2.5 controllability significantly affected whether they were willing to pay. The semi-logarithmic multivariate stepwise regression analysis showed that the factors influencing Beijing residents' willingness to pay were more than PM2.5 's influence on society, the possibility of risk occurrence, the duration of risk and the controllability of risk. However, there are only three factors that influence Nanchang residents' willingness to pay, such as social influence, equality and age.
