成都市居民生活垃圾分类行为意愿研究

Study on Residents’Willingness of MSW Classification in Chengdu

通过引入环境知识、公共宣传、经济激励和情境因素4个解释变量,构建基于扩展计划行为理论的结构方程模型,识别成都市居民生活垃圾分类行为意愿的关键因素,探讨公共宣传对居民环境态度、感知行为障碍、环境知识和分类意愿的作用。结果表明:环境态度、感知行为障碍、环境知识和情境因素对居民垃圾分类行为意愿有显著影响。公共宣传不能直接影响居民的分类意愿,但能通过影响环境态度、感知行为障碍和环境知识间接作用于居民垃圾分类意愿。基于以上结论,为推进成都市生活垃圾分类工作,政府在实施垃圾分类的初期应大力宣传垃圾分类的知识和价值,同时完善城市生活垃圾分类回收配套设施。

By introducing four explanatory variables of environmental knowledge,public propaganda,economic incentives and contextual factors,the structural equation model based on the extended planning behavior theory was constructed.The key factors of Chengdu residents’willingness to MSW classification were identified.Meanwhile,the effect of public propaganda on residents’environmental attitudes,perceived behavior barriers,environmental knowledge and willingness to classify were discussed.The results showed that environmental attitudes,perceived behavior obstacles,environmental knowledge and situational factors had significant influence on residents’behavior willingness of MSW classification.Public propaganda had no direct affect on residents’willingness of classification,but it could indirectly affect residents’willingness of waste classification through influencing environmental attitudes,perceived behavior barriers and environmental knowledge.Based on the above conclusions,in order to further facilitate the classification of MSW in Chengdu,the government should strengthen the propaganda for the knowledge and value of waste classification in the early stage of implementing waste classification,and at the same time,complete the supporting facilities for the classification and recycling of MSW.
