| Summary | To explore the association between motorcycle holding duration and its determinant factors, We developed a design which linked the sampled data for motorcycle usage to the registered motorcycle information recorded in the Taiwan’s Vehicle Registration System. The complete ownership duration of the sampled motorcycle owners could be observed by tracing the motorcycle registration records. Two kinds of Cox proportional hazard models, single risk and competing risk models, were separately applied to construct the regression relationships between the hazard rate of ownership termination and its influential factors including motorcycle conditions, user’s attributes, and aggregate economic variables. The results showed that under the single risk model, the following characteristics, such as owning a used motorcycle, buying a older, used motorcycle at the beginning of owning, owning a motorcycle with a lower displacement and with a higher maintenance cost, running a higher kilometers by the users, having only one motorcycle in the household, and the motorcycle being registered in Great Taipei Area, would raise the hazard ratio as compared individually with their counterparts. In addition, aggregating economic variables including a lower unemployed rate, fewer numbers of passenger cars owned, a higher consuming propensity, and a lower Engel’s coefficient in a city increased the difficulty of terminating motorcycle ownership in the city as well. On the other hand, two different natures of risk-specific events —transferring or discarding a motorcycle while ending its ownership— in the competing risk model revealed different patterns for the independent variables and the sensitivities for the hazard rates. Some variables with ambiguously influential direction and research limitations were also discussed in this study. |
