基于助推理论的低碳出行方式选择OA

[Background]Against the backdrop of accelerating urbanization and rising carbon emis-sions from transportation,nudge interventions are garnering increasing scholarly interest for their role in steering public behavior towards low-carbon transportation options.[Objective]This study aims to explore the impact of nudge interventions on low-carbon travel mode choices during short-distance commuting to provide a scientific foundation for the formulation of low-carbon travel poli-cies.[Method]Two types of nudge interventions were designed:information disclosure and social norms.Data were collected through a travel mode choice behavior survey and analyzed using a mul-tinomial logit model(MNL)to quantify the influencing factors.[Data]Data were collected from 476 commuters in Beijing,representing diverse occupations,income levels,and travel habits.[Result]The implementation of information disclosure and social norm-based nudge interventions increased the probability of low-carbon travel mode selection by 15%and 18%,respectively,and prescriptive social norms demonstrated superior efficacy in promoting bicycle usage.The effectiveness of these interventions showed significant heterogeneity across occupational groups,income levels,and travel routines.Furthermore,travel time and cost acted as critical moderators,as the intervention effects progressively diminished with extended driving duration or increased monetary expenditure.[Appli-cation]These findings provide a theoretical foundation for policymakers to develop tailored low-car-bon transportation policies,particularly by designing specific nudge strategies targeting distinct de-mographic subgroups differentiated by occupational characteristics and socioeconomic status.
