わが国の明治以降の急速な近代化について考えたとき、鉄道はその比類なき輸送力において、経済成長の最大の原動力となったと言ってもよかろう。本研究は鉄道網形成が、実際にどれほどの効用を個人に与えたか、またどれほどGNPに寄与したかを貨幣タームで測定するための理論モデルの作成と、その適用結果について述べたものである。このため、個人は効用最大化行動、企業は利澗最大化行動をとるとの仮定のもとで、簡単なモデルを作成する。そして、鉄道路線長がL0からL1へ、旅客運賃がrp0からrp1へ、貨物運賃がrf0からrf1へ、変化した場合の代表的 (平均的) 個人の効用の変化を測定する。このとき、効用の変化を貨幣タームで測定するために等価的偏差 (Equivalent Variation以下、EVと呼ぶ) の概念を導入する。ここにEVとは、鉄道網整備というサービスをあきらめるために補償してもらいたいと考える必要最低額を言う。本研究では、さらにEVを福祉効果と所得の増大効果とに分け、それぞれについて計算を行う。実際の明治29年における計算の結果は、福祉効果が5億3千万円で、これは当時のGNP28億円の2割弱である。これより、個人は鉄道サービスによりかなり大きな満足を得たと推定できる。さらに所得の増大効果について言えば5億2千万円であり、これもGNPの2割弱である。GNPに対する直接の影響も大きなものであったと言えよう。

For the purpose to simulate the changing process of land use pattern in urbanization, it is necessary to quantify the preference functions of various land users, such as commerce, industry and household.In this paper we have proposed a new method for the estimation of the preference functions by means of statistic discriminant function, which are composed of the accessibility to some urban activities, amenity level and other social and natural environment.First of all, we assumed that the behavior of each land user is making his utility maximum within the limit of the budget for land. Then on this assumption we defined the fact that land user located a certain land means that he prefers it to other lands where he did not locate, and have estimated the preference functions of commerce, industry and household respectively, using data on the land use map of Osaka Prefecture, 1965.The result of the estimation shows as follows: First, each estimated preference function adequately justifies our assumption. Second, the preference function of commerce is similar to that of household, but not to that of industry. Third, the preference function of commerce is strongly effected both by accessibility to the C. B. D. and neighboring land use; that of industry by the industrial water supply and that of household by accessibility, construction cost and public utility level.

The estimation of the economic benefits of a public investment project should include not only the direct effects but also the indirect ones. The problem is seen even more clearly when considering projects involve investments for increasing assets in social overhead capital, such as roads, railways, ports, etc. These projects often show a direct benefits only, which may be less than unity if the services produced are not sold, but consideration of the benefits deriving from the execution of such projects often shows that they are of top priority. In these cases the most important benefits are indirect, since they make production possible in other sectors of the economy.In this drafting, we deal with an estimation of direct and indirect economic benefits to a region which derived from the public investment for port facilities, by preparing a simplified system as shown in Fig. 1.Thereupon, such economic benefits are defined as an increment of the net regional products. Then the econometric model and interregional input-output model are introduced to analyze each process of this system mentioned above.
