Abstract

This study used the contingent valuation method (CVM) to investigate and analyse the current status of household solid waste management and evaluate people’s consensus and willingness to pay (WTP) for household solid waste collection, transportation, and treatment services among urban, rural, and mountainous areas in Hanoi. It also utilised regression analysis to assess factors affecting people’s WTP. The study surveyed a sample size of 405 households. To ensure a basis for comparison among urban, rural, and mountainous areas, the study distributed and conducted an equal number of 135 surveys in each area through random sampling. The research results indicate that the average household solid waste in Hanoi is highest in urban areas at 1.27 kg/household/day, followed by rural areas at 1.21 kg/household/day, and mountainous areas at 1.067 kg/household/day. However, most household solid waste has not been classified at the source. Regarding WTP for household solid waste collection, transportation, and treatment services, the results show that 85% of urban households agreed to pay higher than the proposed price, with an average WTP of 1,136 VND/kg. In rural households, 47% agreed to pay 778.96 VND/kg, and 11% of mountainous households agreed to pay an average of 673.04 VND/kg. These insights can guide tailored waste management pricing strategies across diverse urban and rural settings.
河内家庭固体废物管理服务价格计算方案的家庭支付意愿研究
本研究采用或然估价法 (CVM) 调查和分析河内城市、农村和山区的家庭固体废物管理现状,并评估人们对家庭固体废物收集、运输和处理服务的共识和支付意愿 (WTP)。研究还利用回归分析法评估了影响人们 WTP 的因素。研究调查了 405 户家庭样本。为确保在城市、农村和山区之间进行比较,研究通过随机抽样的方式在每个地区分发并进行了同等数量的 135 份调查。研究结果表明,河内市的平均家庭固体废物量最高,为 1.27 千克/户/天,其次是农村地区的 1.21 千克/户/天和山区的 1.067 千克/户/天。然而,大多数家庭固体废物并未在源头进行分类。关于家庭固体废物收集、运输和处理服务的 WTP,结果显示 85% 的城市家庭同意支付高于建议价格的费用,平均 WTP 为 1,136 越南盾/公斤。在农村家庭中,47% 的家庭同意支付 778.96 越南盾/公斤,11% 的山区家庭同意支付平均 673.04 越南盾/公斤。这些洞察力可为不同城市和农村环境中量身定制的废物管理定价策略提供指导。
