Understanding the key factors determining rural domestic waste treatment behavior in China: a meta-analysis

The growing interest of policy-makers, environmental stakeholders, and academics in rural domestic waste treatment has made it a recent focus of research in the field of rural human settlements. Many studies have been conducted to understand the related factors; however, their results are inconsistent. Therefore, different from previous studies, the study systematically analyzed and summarized empirical studies on rural domestic waste treatment and explored the key factors that fostered and impeded it. It also examined the reasons for differences in research level and trends in key factors over time. A random-effects meta-analysis of 24 studies revealed that education, political status, perceived value, behavioral attitude, subjective norm, garbage collection facilities and services, environmental knowledge and propaganda, and government policy and regulation had a significant positive correlation with rural domestic waste treatment; perceived value had the highest impact, followed by behavioral attitude. All of the variables had significant heterogeneity. Some of the heterogeneity can be explained by differences in research methods, sample size, and variable measurement methods. An increasing trend was observed in the effects of perceived value, behavioral attitude, and subjective norm. Finally, based on these results, the study provided suggestions on policy and academic aspects.
