As the process of urbanization in China continues to accelerate, the amount of domestic waste generated correspondingly increases and directly affects the living space of residents. This indirectly implies that to reduce the production of municipal solid waste and the need for garbage disposal and recycling, household-waste-classification activities by the residents are of great significance. Using Shanghai as a case study, this study investigated the influencing factors on residents' household waste classification by conducting a survey. Statistical analysis was then adopted, which is specified below. First, this study proposed research hypotheses related to the influencing factors of residents' domestic-waste-sorting behavior from three levels: government, society and individuals. Second, the study designed a questionnaire from five perspectives: individual characteristic variables, government, society, residents and classification behavior. Then, SPSS software was used to carry out descriptive statistical, reliability and validity assessments using ANOVA, correlation and regression analyses on the sample data obtained from the questionnaire. The results suggested that the research hypotheses were statistically significant: (1) females and residents with higher education were more likely to participate in domestic waste classification; (2) reward and punishment measures had the most significant impact on residents' waste-classification behavior; and (3) publicity and education, classification standards, classification facilities, the recycling system, subjective norms, environmental knowledge and environmental attitudes all had a positive effect on residents' household waste classification. Finally, based on the results of the empirical analysis, this paper provides reference suggestions for the further development of domestic waste classification in Shanghai.
随着中国城市化进程的不断加速，城市生活垃圾的产生量也相应增加，直接影响到居民的生活空间。这就意味着为了减少城市生活垃圾的产生和垃圾处理及回收的需求，居民进行生活垃圾分类具有重要意义。本研究以上海为例，通过问卷调查的方式研究居民生活垃圾分类的影响因素。采用统计分析法，首先从政府、社会和个人三个层面提出了与居民垃圾分类行为相关的研究假设，其次从个人特征变量、政府、社会、居民和分类行为五个方面设计了问卷，然后使用 SPSS 软件对问卷调查获得的样本数据进行描述性统计、信度和效度分析，以及方差分析、相关分析和回归分析。结果表明，研究假设在统计上是显著的：（1）女性和受教育程度较高的居民更有可能参与垃圾分类；（2）奖励和惩罚措施对居民垃圾分类行为的影响最大；（3）宣传教育、分类标准、分类设施、回收系统、主观规范、环境知识和环境态度对居民的生活垃圾分类都有积极影响。最后，根据实证分析的结果，为上海市进一步推进生活垃圾分类提供参考建议。
