Abstract
To effectively deal with the waste management problems faced by cities, it is of great significance to promote the sorting and recycling of municipal solid waste. Given the correlation between individual behavior and psychological preferences and external situations, this study explored the mechanism of individual preference framework and group preference framework in the impact path of product facilities on residents’ waste-sorting behavior. Based on a questionnaire survey (N = 1505), combined with correlation analysis, difference analysis, hierarchical regression analysis, sensitivity analysis, and other methods, the study found that differences in residents’ age, education background, and monthly income lead to differences in residents’ sorting behaviors, and individuals of young age and low monthly income have higher sorting behaviors than others. Interestingly, highly educated individuals did not show high sorting behavior. Both individual preference and group preference frameworks play a regulating role in the influence path of product facilities on waste-sorting behavior, but a group preference framework (including family preference, organizational preference and social preference) plays the more significant regulating role. Additionally, social preference variables are the most prominent regulatory factors and have a greater “amplifier” effect in the impact of product facilities on waste-sorting behavior. Based on these findings, this study identifies the corresponding policy implications.
Highlights
In recent years, the problem of municipal solid waste (MSW) globally has become increasingly serious
Given the correlation between individual behavior and psychological preferences and external situations, this study aims to explore the mechanism of individual preference framework and group preference framework in the impact path of product facilities on residents’ waste-sorting behavior
Waste-sorting behavior; difference analysis is used to compare the impact of individual differences on residents’ waste-sorting behavior; hierarchical regression analysis is used to explore the mechanism of preference framework in the path; sensitivity analysis is used to compare the difference between individual preference framework and group preference framework in the path
Summary
The problem of municipal solid waste (MSW) globally has become increasingly serious. SPSS 17.0 was used to explore the specific differences of residents’ waste-sorting behavior in terms of gender, age, education background, and monthly income, based on the independent sample t-test, one-way variance test, and comparison of mean values. The independent sample t-test was conducted on gender, the one-way variance test was conducted on age, educational background, and monthly income variables, and the average score of waste-sorting behavior of each respondent group was calculated. In the one-way variance test, the p-value of the age variable was 0.045, the p-value of the education background variable and the monthly income variable were 0.000; because all of these values were less than 0.05, the waste-sorting behavior of urban residents was significantly different among respondents of different ages, and among those having different education backgrounds and monthly incomes.
