小汽车依赖性的综合测度及其影响因素研究
Research on the comprehensive measurement of car dependence and its influencing factors
摘要
Abstract
To address the issues of existing methods for measuring car dependence,including their single-dimensional focus and lack of clarity regarding influencing mechanisms,this study conducts a comprehensive analysis of car dependence and its influencing factors,using travel survey data collected from car users in Kunming.Incorporating three dimensions,which are objective dependence,subjec-tive dependence,and car usage conditions,the study employs a second-order structural equation model to comprehensively measure car dependence and analyze group-level differences.Subsequently,the Gradient Boosting Decision Tree(GBDT)model and the Shapley Additive exPlanations(SHAP)model are applied to explore the influence mechanisms of socio-economic attributes and built environ-ment on car dependence.The results indicate that the loading coefficients for objective dependence,subjective dependence,and car usage conditions are 0.725,0.242,and 0.852,respectively.Car de-pendence is constrained by car usage conditions,with objective dependence proving stronger than sub-jective factors,and varying significantly across demographic groups.The objective built environment accounts for 62.48%of the variance in car dependence,higher than 29.87%for socio-economic attri-butes and just 7.46%for the perceived built environment with a relatively low influence.The influence of the built environment on car dependence also exhibits nonlinear relationships and threshold effects.These findings present a novel framework for measuring car dependence and provide valuable insights for developing targeted strategies to reduce car dependence.关键词
