Influence of built environment and socio-economic status on residents’ low-carbon lifestyle: An empirical analysis of Zhengzhou city, China
摘要
A low-carbon lifestyle presents new opportunities for sustainable urban development. While previous studies have verified the impact of the built environment and socioeconomic status (SES) on low-carbon lifestyles, they have primarily focused on direct effects. At present, there is still a lack of analysis on the interaction effects on low-carbon lifestyles, and limited attention has been given to the peer effect in low-carbon lifestyles, especially in the context of residential differentiation. Therefore, we take Zhengzhou city as the case area and first calculate the low-carbon lifestyle of 1485 families from three dimensions: low-carbon action (A), low-carbon interest (I) and low-carbon opinion (O). We then analyze the direct and interactive impacts of the built environment and SES on low-carbon lifestyles and explore the peer effect. Our findings indicate that families with higher SES have higher levels of low-carbon interest and low-carbon opinion, but relatively low levels of low-carbon action. This suggests an interest-action bias in the low-carbon lifestyles of high-SES families. POI density, road network density and accessibility positively affect low-carbon lifestyles—that is, residents living in areas with well-developed infrastructure and convenient transportation tend to be green in their daily behavior. The peer effect influences low-carbon action, interest, and opinion by 54.6%, 34.9%, and 16%, respectively, indicating that the peer effect is most evident in low-carbon action. That is, the peer effect is more obvious in low-carbon action. In addition, the built environment affects the low-carbon lifestyles of different SES groups. Land-use mix positively increases low-carbon action and low-carbon interest among high-SES groups but reduces low-carbon opinion. Road network density positively affects the low-carbon action of high-SES groups and the low-carbon interest and low-carbon opinion of low-SES groups. This study explores low-carbon lifestyles from a situational perspective, providing a practical basis for policies aimed at accelerating a transition to sustainable living.
