ABSTRACTBy constructing a socioeconomic model within the framework of the multi regional general equilibrium theory, this paper proposes ii matrix fur an urban transport improvement project that illustrates thy relationship between benefit generation and incidence. On this matrix the benefit/loss associated with each sector (household, private firm, absentee landowner, public transport corporation, and government) and associated with each item (transport, land, tax, fare revenue, and project surplus/loss) are indicated clearly, so that the social efficiency and equity of the project can easily be discussed.
