Abstract: Previous researches in activities-decision have more in-depth study in context of individuals, while less work has been done on household activity decisions. The structural equation model is applied to analyze the relationship of three household activity categories on holiday using data from 2009 Jinan travel survey. Six attributes were first chosen as exogenous variables for the structural equation model. Meanwhile, six activity characteristic indexes were selected as endogenous variables including activity duration time and activity times in three kinds of activity, hereby subsistence activity, maintenance activity and discretionary activity, respectively. Then, the paper attempted to discuss the correlation of all types of activities behavior through analyzing not only the influence of household economics and family members factors on activity but the correlation of holiday activities. The research shows that complex relationships among composition of the family, economic status, and activities-decision can be captured by the structural equation model structure. Specifically, the results show that flexibility of three categories activities will affect the activities of decision-making.

摘要： 当前对于个人外出活动的研究较为深入，而家庭为单位的活动研究存在不足. 为了确定假日家庭活动安排的影响因素和不同活动之间的影响关系，本文以家庭为单位，使用2009年济南居民出行调查数据，选取6个家庭因素作为外生变量；以生存性活动、维持性活动和自由活动——活动持续时间、活动次数为内生变量，考虑家庭的成员属性和经济属性，建立结构方程模型. 重点分析了家庭人口因子和家庭经济因子对三类活动因子的影响关系和各类活动之间的关联性. 结果表明家庭人口因子和家庭经济状况因子对于三类活动的决策有显著影响. 同时三类活动之间根据活动本身的弹性，影响关系也有所不同.
