This paper aims to analyze a panel data of shopping travel behaviors focusing on their dynamic properties. While an activity-based panel survey has been conducted once each year for three years since 1989,the panel data sets obtained are composed of the three wave data sets including refreshments in each wave as well as full-stayers in the panel. After the outline of this panel survey is introduced, a panel attrition analysis is introduced from the viewpoint of factors significantly determining participation in the panel survey. Also the causal structure underlying the panel attrition is examined by using a log-linear model. Basic properties related to "dynamics" of travel and activity linkages over time are also examined. The results show that, occupation, car-ownership, and life-cycle stage are classified into a strongly associated group and that there exists in irreversibility in the state transition over time among some of the factors affecting on the shopping travel patterns.
