本实证研究以河内市为研究对象，从整个大都市圈收集了778个样本进行问卷调查。利用偏最小二乘结构方程模型，本文旨在确定影响垃圾分类行为的因素，特别考虑到这样一个快速发展的城市的人口和生活方式的重大转变。居住期限（或居民在当前房屋中居住的年数）被发现是区分河内公民最强行为预测因素的一个因素。具体来说，定居10年或更长时间的人更受权威信任的影响，而10年以下的居民最受机会（对激励和便利的反应）的激励。社区意识和内部因素能力（进行源头分类的能力）对垃圾分类行为的影响也得到了证实。这些结果表明，除了改善基础设施、地方行政体系和废物管理体系外，还应考虑着眼于长远城市规划、确保稳定的居住环境以增强居民的社区意识以及与社区领袖的社会联系等政策，以提高源头分类的参与率。
In this empirical study, a questionnaire survey targeting Hanoi City was conducted, gathering 778 samples from the whole metropolitan area. Using partial least squares structural equation modeling, this paper aims to identify the factors influencing waste separation behavior, with special consideration to the momentous shift in the demographic and lifestyle of such a fast-growing city. The living period (or the number of years that a resident stays in the current house) is found to be an element that differentiates the strongest behavior predictors of Hanoi citizens. To be specific, people who have settled down for 10 years or more are more influenced by Trust in Authority, while residents of less than 10 years are most motivated by Opportunity (responsiveness to incentives and convenience). The effect on waste separation behavior by Sense of Community and the other internal factor, namely Ability (the capacity to carry out source separation), were also confirmed. These findings indicate that, besides improving infrastructure, local administrative systems, and waste management systems, it is also important to consider policies focusing on long-term city planning, securing stable living situations to enhance the residents’ sense of community and the social link with community leaders to achieve a higher rate of source separation participation.
