研究在校大学生的校外出行方式选择行为,对于改善高校学生的校外出行环境、提高社会参与度、促进其身心健康发展具有重要意义。已有研究忽视了同伴群体对个体出行方式选择的影响。该文针对缺乏统一标准确定大学生有效群组的不足,通过室友关系质量量表界定有效群组,基于问卷调查获得不同出行场景下在校大学生的校外出行偏好数据;为补充同群效应在出行行为决策中的作用机制研究,从关系质量与心理特性出发,引入关系强度调节的同伴矩阵并构建多个同群效应的网络经济学线性模型,结合固定效应和两阶段最小二乘法解决潜在的内生性问题,通过模型评估确定识别和测度同群效应的最佳模型;基于模型标定结果分析宿舍群体对在校大学生个体校外出行方式选择的影响和潜在作用机制。结果表明:相较于广义计量模型和局部聚集模型,考虑关系强度的局部平均模型在识别和测度同群效应时具有更好的稳健性;随着出行距离的增加以及出行时间约束的放松,在校大学生个体出行方式选择行为受同伴相关行为的影响程度(即内生同群效应)降低;同伴的月生活费、家庭成员人数、有无驾照、开放性及环保意识等因素对在校大学生个体出行方式选择具有显著的外生同群效应;外向型个体相较于内向型个体具有更为显著的从众性同群效应,休闲娱乐场景下开放型个体比保守型个体的从众性同群效应更显著。该研究拓展了相关理论边界,可为高校低碳出行的精细化引导与分群体干预提供实证依据。
