Defayment Method of Transport Project Cost by Using Benefit Incidence Matrix

通过在多区域通用均衡理论的框架内构建社会-经济模型，我们理论上讨论了城市交通改善益处之间的生成和事件的机制，并提出了一个用于城市交通改善项目的好处事件矩阵，在那里我们可以确定好处分配结构。1989年第一年这项研究的结果，按以下顺序排列。（1）每个列在这个有利事件矩阵中的总价值表明每个部门的有利/损失，每个行的总价值表明每个项目的有利/损失。在这个基础上，我们可以讨论项目的社会价值和有效性。（2）如果使用这个有益的事件矩阵，那么就有可能讨论问题，讨论发展收益的恢复，因为在这种情况下，有益的一代和事件之间的关系在这个矩阵中被清除了。（3）这是有可能评估项目的影响，将改变居民和工业位置，因为每个社会的行为--经济部门将在多部门一般均衡理论的框架内形成。（4） The social net benefit from the project can be measured only with the transport related information using the short cut measurement method.The model developed here is applied to the case study on the measurement of the benefit incidence of the usual （toll free）inner-city ring road construction in GifuCity， Japan。本实验研究在过去一年的结果， 1990年，地区继续跟进。（1）因为Landowners' share of the Total Road Benefits为83.4%，所以它可以说，Gifu Metropolitan area是一个介于小-开放和大-封闭区域之间的中间情况。（2）本估计结果认为，这是公平和有效的，以建立这样一个发展增益恢复系统的较高恢复率，以实现工业土地和较低的居住地。

By constructing a socioーeconomic model within the framework of the multiーregional general equilibrium theory, we theoretically discussed the mechanism between generation and incidence of urban transport improvement benefits, and proposed a benefit incidence matrix for the urban transport improvement project, which can indicate the benefit distribution structure. The results of this study in the first year, 1989, are as follows. (1) The total value of each column in this benefit incidence matrix indicates the benefit/loss of each sector and the total value of each row indicates the benefit/loss of each item. On this basis, we can discuss the social equity and efficiency of the project. (2) By using this benefit incidence matrix, it will be possible to discuss the problem concerning the recovery of development gains, because the relationship between the benefit generation and incidence is made clear in this matrix. (3) It will be possible to evaluate the effect the project will have on the change of residential and industrial location, because the behavior of each socioーeconomic sector is formulated within the framework of the multiregional general equilibrium theory. (4) The social net benefit from the project can be measured only with the transport related information using the shortcut measurement method.The model developed here is applied to the case study on the measurement of the benefit incidence of the usual (toll free) innerーcity ring road construction in GifuCity, Japan. The results of this experimental study in the last year, 1990, areas follows. (1) Because the landowners' share of the total road benefits is 83.4%, it can be said that the Gifu Metropolitan area is an intermediate situation between smallーopen and largeーclosed area. (2) This estimation results suggest that it is fair and efficient to establish such a development gain recovery system of the higher recovery rate for industrial land and lower for residential land.
