认知对农户参与生活污水处理设施管护意愿的影响——基于南水北调中线水源地的农户调查

Influence of cognition on farmers’willingness to participate in the management and protection of domestic sewage treatment facilities:Base on a Farmer survey in water source area of the middle route of South-to-North Water Diversion Project

为探究农户认知对生活污水处理设施管护意愿的影响机制。基于计划行为理论分析框架,运用单边界加支付卡式的改进条件价值评估法(CVM),以南水北调中线水源地450户农户微观调查数据为基础,采用Heckman两阶段模型分析农户付费行为差异及关键因素。结果表明:不同生活污水治理模式下样本农户同意进入付费情景的概率不同,支付意愿也不同,没有接入任何污水处理设施的农户同意支付概率与支付水平均最低。农户参与生活污水处理设施管护意愿逻辑符合计划行为理论,行为态度、主观规范、感知行为控制、年龄、是否是党员、健康状况、家庭总收入变量均对农户付费行为有显著影响。综上,应充分发挥南水北调中线水源地农户认知对其参与生活污水处理设施管护的促进作用,鼓励党员、以及环保意识较强的农户率先参与污水处理设施管护,部分地区可探索推行受益农户适当缴费或出工等管护方式。

The purpose of this study is to explore the influence mechanism of farmers’cognition on the management and protection behavior of domestic sewage treatment facilities,based on the theoretical framework of planned behavior.this study uses the micro survey data of 450 farmers in the water source area of the middle route of South-to-North Water Project,Heckman two-stage model to analyze the differences and key factors of farmers’payment behavior.The results show that:Under different domestic sewage treatment modes,the probability and willingness to pay of surveyed farmers are different.The probability and level of farmers who do not have access to any sewage treatment facilities are the lowest.The indexes of behavior attitude,subjective norm,perceived behavior control,age,whether aparty member,health status and total household income display significant effects on farmers’payment behavior.The behavior logic of farmers’participation in domestic sewage treatment and management conforms to the theory of planned behavior.Variables including behavior attitude,subjective norm,perceived behavior control,age,whether CPC Party member or not,health status and total family income have significant effects on farmers’payment behavior.Therefore,farmers’cognition should be given full play in promoting their participation in the management and protection of domestic sewage.The Party members and farmers with strong environmental awareness are encouraged to take the lead in the management and protection of sewage treatment facilities.In some areas,the implementation of domestic sewage treatment and protection methods,such as the appropriate payment or work by the beneficiary farmers could be explored.
