采用结构方程模型分析方法,建立了社会准则、问题感知、责任归属、愿意行动、感知有效、感知利益、感知公平、感知自由与公众可接受性之间的结构方程模型,通过意向调查获得了A,B2种收费方案的437份问卷,在此基础上对模型进行了评价和修正.结果表明在费率较大的B方案下感知有效对感知自由以及感知自由对感知利益的影响更加显著；在费率较低的A方案下,感知公平对可接受性的直接影响最大,B方案下感知有效的影响最大,但2种方案下影响最大的直接因素均为感知有效和感知公平；间接影响因素中,愿意行动对措施可接受性的影响最突出,且愿意行动作用于感知有效,但对感知公平影响较小.%According to the structural equation theory, the structural equation model is established, which considers the relationships among social norms, problem awareness, liability, willingness to act, perceived effectiveness, perceived interest, perceived fairness, perceived freedom and public acceptance of congestion pricing. Based on 437 responses of a questionnaire survey including A and B price collection schemes, the model is evaluated and modified. The results show that the relationships between perceived effectiveness and perceived fairness, and between perceived fairness and perceived interest are more remarkable under scheme B, which has a high pricing rate. The perceived effectiveness that directly influences the measured acceptability is the biggest in the scheme B. In both schemes the perceived effectiveness and perceived fairness are always the two direct factors having the biggest effect on acceptability. Among the indirect influencing factors, the willingness to act has the most striking effect on the acceptability. Furthermore, willingness to act also plays a role in perceived effectiveness but makes no difference on perceived fairness.
