 note = {論文(Article), The purpose of our research project is to develop a new integrated model for explaining interregional telecommunication demand not only by traditional phones such as ordinary and public phones but also by mobile phones such as personal handy and cellular phones. In the empirical research, the first traffic data on ordinary, public and mobile telephone services is used. This paper attempts to explain the demand on interregional phone services based on the same framework of travel demand analysis, unlike most economic models which estimate the demand or supply curve without considering information flow from origin to the destination.},
