This study aims to outline methods for construction of main farm roads, giving consideration to a broadened agricultural distribution. The link function of main farm roads consists of agricultural products transportation time and the reduction of these transportation costs. These effects are realized, for agricultural products transportation, by Link I leading from the cultivated fields to agricultural facilities and Link II leading from there to Node II (the destination market, terminal, container base) . For agriculutural products transportation, when the sharing rate of transportation facilities for a transported item is decided, the location of Node II to be accessed is selected and Link II is consequently decided. The sharing rate is decided by considering such factors as a place of shipment, destination, shippingseason, and market price, in addition to factors of transportation cost, time, service level, etc.
a. The selection of JR transportation benefits transportation cost rather than freshness.
b. The selection of air tranportation gives top priority to freshness and transportation time, and copes with high freight by transporting item which have high market price and thus can bear freight.
c. The selection of ferry transportation stands between JR and air transportation. It presently has an advantage over JR transportation in freshness and transportation time, and ferry transportation is an alternative for productsw hosemarket price has dropped, making air transport too expensive.

The land exchange between “Urban Developing Area”and “Farm Land Area” has attracted the attention of many people as a method for controling land use in urban fringe. Actually the land exchange by the existing methods (“Ryokuno-Juku” project and so on) is very difficult. But in Matsuto City, the unique method for land exchange was devised, so that there were many cases of land exchange. In this paper, we studied on the case of Matsuto City as following points.
1) We presented “Matsuto Method” that is very effective for land exchange. The characters of “Matsuto Method” is as follows:
a) Exchanging lands on the occasion of urban development.
b) Conditioning that the size of exchanged lots is equal to adjust the equivalence of them.
c) Making use of the function of rural self-government.
2) We made models of land exchange for the framework of analysis.
3) We proposed some conditions for land exchange.

Many problems with resort development are reported in recent years. But there are few analyses which are aiming at the economic effects by resort developments in such reports. This paper analyzed the economic spread effects by a ski area development at Ashiro town in Iwate prefecture.
We made clear the change of the development by processing several statistical data of the town. And we considered that grasping actual living conditions of the residents was important, so we interviewed not only the public office of Ashiro town or the head office of Appi-kogen ski area but also many living people of the town. Through such works, the following facts are proved:
1. The population of the town did not increase, and the agriculture or the manufacturing industry were hardly influenced by the development;
2. Many good influences were recognized in the building industry, the sales of tenant stores in ski area and the employment of the town;
3. Especially, seasonal emigrant workers decreased drastically because many inns were opened by the residents and employment opportunities were appeared.
We can mainly point out two factors for these favorable effects. First, the development was the large scale project and it succeeded in calling many skiers. Second, the development firm was “the 3rd sector system” (which was invested by both public and private sector) and it produced many business chances for the residents.
