人居环境工作满意度何以影响农户付费意愿--基于农村生活污水治理付费的实证研究

Why does Satisfaction of Living Environment Service Affect Rural Residents'Willingness to Pay:An Empirical Study of Rural Sewage Treatment Payment

农村生活污水治理付费不仅是治理资金不足的解决手段,也关乎农户环境参与凝聚力。运用闽、皖、陕3省529户农户微观调查数据,基于双栏模型(DHM)实证分析人居环境工作满意度对农户生活污水治理付费意愿的影响机理。结果表明:环境工作满意度对农户生活污水治理付费意愿具有显著促进作用,且县乡政府层面的环境工作满意度的促进作用要强于对村委会层面,但环境工作满意度对付费意愿的影响主要体现在支付水平上;中介机制检验发现,价值认同起到中介效应(强化了促进作用),而风险感知起到遮掩效应(削弱了促进作用),家庭总收入起到门槛效应(仅当农户家庭总收入在5.8万元/年以上时促进作用才具有稳定的显著性)。据此,相关单位要增强环境工作实效,办农民满意的环境整治,并着力提高农户对环境整治的认可度和信心,以此赢得农户对生活污水治理的付费参与。

Rural sewage treatment payment is not only a solution to the shortage of treatment funds,but also related to the cohesion of rural residents’environmental participation.Based on the micro survey data of 529 farmers in Fujian,Anhui and Shanxi provinces,this paper empirically analyzes the impact mechanism of residential environment job satisfaction on residents’willingness to pay for sewage treatment based on double column model(DHM).The results show that environmental job satisfaction can significantly promote residents’willingness to pay for sewage treatment,and the promotion effect of environmental job satisfaction at the county and township government level is stronger than that at the village committee level,but the impact of environmental job satisfaction on willingness to pay is mainly reflected in payment level.The test of intermediary mechanism found that value identity played an intermediary effect(strengthened the promotion effect),while risk perception played a masking effect(weakened the promotion effect),and total household income played a threshold effect(the promotion effect was stable and significant only when the total household income was more than 58000 RMB/year).Accordingly,relevant units should enhance the effectiveness of environmental work,do environmental remediation to the satisfaction of residents,and strive to improve rural residents’recognition and confidence in environmental remediation,so as to promote their participation in sewage treatment.
