基于家庭属性差异的大学生出行方式选择行为研究

为剖析家庭属性差异对大学生出行方式选择行为的影响，基于非集计理论，构建家庭属性差异的大学生出行选择多元Logit 模型. 根据四川省2 571 份大学生出行行为调查问卷，运用SPSS 软件标定模型参数，获取影响大学生出行选择的主要家庭属性因素，并进行敏感性分析. 结果表明：家庭平均年收入、经济净流对大学生出行方式选择有显著的影响；以航空运输为参考，家庭平均年收入、经济净流对公路运输方式选择的影响大于铁路运输；“祖辈替孙辈购买机票”的折扣票务形式可提高大学生选择航空出行的概率.

Choice of Travel Mode for College Students Based on Family Attributes

In order to analyze the influence of family attribute differences on college students' travel mode choice behavior, based on the disaggregate theory, a multivariate Logit model is constructed for college students' travel mode choice behavior. Based on the travel behavior surveys from 2 571 college studentsin Sichuan Province, the model parameters are calibrated using SPSS. The main family attribute factors affecting college students' travel choices are obtained, and the sensitivity analysis on the factorsis conducted. The results show that the average annual household income and economic net income have a significant impact on the choice of college students' travel modes. Compared with air transport, the average annual household income and economic net income have a greater impact on the choice of road transport and lower impact on rail transport. The discount ticketing form of grandparent purchasing tickets for their grandchildren can increase the probability that college students choose to travel by air.
