收入水平、村干可信度对农户生活垃圾治理意愿影响分析——基于云南省465个农户调研数据

The Influence of Rural Household Income and Trust in Village Leaders on Households′ Willingness to Treat the Domestic Solid Wastes: Based on Survey Data of 465 Households in Yunnan Province

农村生活垃圾治理事关广大农民根本福祉,是乡村振兴战略中"生态宜居"的重要内容。基于云南省昭通市渔洞水库汇水区465个农户调研数据,利用双栏模型(Double Hurdle Model)实证分析农户收入水平、村干可信度对农户生活垃圾治理意愿(参与意愿及支付意愿)的影响。结果表明:农户生活垃圾治理意愿较高,有86.9%的农户愿意为生活垃圾治理支付费用,支付意愿的均值为45.616元/户/年;收入水平对农户生活垃圾治理支付意愿具有显著正向影响,村干可信度对农户生活垃圾治理参与意愿、支付意愿均具有显著正向影响;村干可信度对农户收入水平-支付意愿之间的关系存在显著的正向调节效应,对村干部信任程度高的农户,收入水平对支付意愿的促进作用更强。此外,年龄、家中负担人数、家中是否有村干部、家中常住人口数量等个人特征和家庭特征也对农户生活垃圾治理意愿产生影响。对比农户参与意愿和支付意愿两栏的结果,可以发现年龄、家中负担人数、家中有村干部、地区等变量在影响方向和程度上存在差异,说明农户参与和农户支付是两种不同的机制,需要区别对待才能更好洞悉农户意愿。实现以农户收入为核心的经济因素和以村干可信度为核心的非经济因素的合理配合是促进农户参与生活垃圾治理的关键。

Management of rural domestic waste is one of the important parts of the national rural revitalization strategy, and related to the fundamental well-being of rural residents. This paper is to study the impacts of household income and trust in villager leaders on households’ willingness to treat the domestic solid wastes in a way that is prescribed by the government. The study was based on a questionnaire survey of 465 households in catchment areas of Yudong Reservoir in Zhaotong, Yunnan Province. A Double Hurdle Model is employed in this empirical study. The results show that 86.9% of households are willing to pay for the treatment of domestic solid wastes with an average willingness to pay of CNY45.616/year, which are fairly high. Household income and trust in villager leaders have positive impacts on households’ willingness to participate in and willingness to pay for treatment of domestic solid wastes. Trust in villager leaders has a reinforcing effect on the relationship between household income and their willingness to pay for the treatment of domestic solid wastes. More trust in villager leaders by householders, more impacts the household income will have on household willingness to pay. Moreover, personal and family characteristics such as householder age, number of persons to afford in a household, whether there is a village leader in the household, and number of persons in a household have effect on households’ willingness to participate in the treatment scheme. Comparing the results of households’ willingness to participate and willingness to pay, it can be concluded that there are differences in the direction and degree of influence of variables such as householder age, number of persons to afford in a household, whether there is a village leader, and area. This shows that household participation and household payment have two different mechanisms, and need to be treated differently to better understand rural households’ willingness. Realizing the reasonable coordination of economic factors with household income as the core and non-economic factors with the trust in village leaders as the core is the key to promoting households’ participation in rural domestic solid wastes management.
