Effective demand creation due to the public investment is important factor for the activation of regional economy. This effect is called the flow effect of the project. The purpose of this paper is in analyzing how much effective demand can be created by the public investment project in the region. For this purpose, I improve the regional I/O model classified by road construction project, sewer and park construction project and agricultural and forestry development project. And I calculate the amount of production and the number of workers caused by the execution of each project. The results are as follows.
At first, as shown in the inverse matrix coefficients, if we ignored the land and compensation fee rate and the regional distributive conditions of the budget, the effect of each public investment project becomes almost same level. But by the kind of project, there are some differences in land and compensation fee rate, and in regional distributive conditions of the budget. Due to these differences, the flow effect varies in the kind of project and the region. For example, this effect of sewer and park construction project is remarkable in the urban prefecture, and this effect of agricultural and forestry development project is biggest in the rural prefecture. The road construction project has little effect in both of the urban and the rural prefecture, compared with other projects.
Secondly, in all kinds of public investment project, not only the local project induces the production inthe rural prefecture but also it induces the production in the urban prefecture, through out the industrial structure. In agricultural and forestry development project, the amount of production that flows from the rural prefecture to the urban prefecture is more about 10% of the whole. Other most parts influence the rural economy.

Investment boom in Vietnam which had started from 1988 brought many changes not only in urban area but also rural area. For example, foreign manufacturing plants had located in rural area. In 1997, rural area had more numbers of foreign direct investment than urban area (Rural area: 180 projects; Urban area: 159 projects). This report focuses on Japanese direct investment and expropriation of land in the suburban villages of Hanoi city.
Firstly; the author highlights legal notions of land in“The 1992 Constitution of the Socialist Republic of Vietnam, Land Law and Foreign Investment Law”. Special features of legal notion are as follows; 1) The rights of land ownership belongs not to the State but the entire people. 2) The State manages all the land in accordance with plan and law. 3) The provincial people's committees of each locality in which the investment project is located has the responsibility to organize compensation and site clearance.
Secondly; the author reports actual of expropriation of land by Japanese enterprises. The following two points of issue are in matter when enterprises expropriate land. 1) In cases of the expropriation of agricultural land, the enterprises have to compensate farmers for their loss. It takes a lot of time to delineate the land for compensation, because a system of land registration have not been established in Vietnam. 2) Squatters appears to occupy to the site after finishing expropriation of land, however, the police can not force to repel squatters from the site. Because Vietnamese generally regards the right of Land ownership belongs not to the State but to the entire people.
Manufacturing plants seem to continually locate in rural area in Vietnam. So, it has been impossible to grasp the conditions of rural area only by agricultural side. It is necessary to pay attention how the Vietnamese State will solve aforementioned issues and reform rural areas by implementation of planning.
