Public works for the purpose of social capital will have to change in the future. Conventional public works include the development of infrastructure such as industrial infrastructure such as roads, bridges, bay ports, fishing ports, airports, sewage systems, housing, parks, waste disposal facilities, afforestation, and the development of disaster prevention infrastructures such as flood control. Criticism of public works has erupted. The main reason for this is that public works have been positioned as a pillar of fiscal policy for economic stimulus since the period of high economic growth. Although there is no objection to using public works for economic measures, only the aspects of the economic stimulus measures have been emphasized in the Japan, and the business content has been neglected. The symbol is a basic plan for public investment of 630 trillion yen, which was pledged to the United States (from 1995 to fy2007). It is that the total amount of the public works expense has been decided first without being asked whether it is public nature for whom in the region.
As a result, public works will not escape the wasteful type of concession, the regional environmental destruction type, and the slander of the regional community destruction type. When we look at public works in various parts of the world, environmental regeneration and environmental harmony and utilization are becoming mainstream. In addition to the restoration and restoration of the natural environment, which has deteriorated, the preservation of the natural environment in existence, and the next generation of sustainable social capital. Such a public work has no immediate effect, and even if the short-term cost seems to be costly, compared with conventional public works, it brings about economic effects in the long term. In the Japan, the concept of social capital development, such as resource recycling, conservation of the natural environment, and developing new energy, in line with the realization of a recycling-oriented society, is sparse in public works. The quality change of public works has begun in some parts of Japan country. In the request of a certain ministry to the southern island of the south, my work is to shift the introduction of the traditional public works expense to the preservation of the recycling, the natural energy, and the natural environment which aspirations the nature and the social resources of the island. The direction and content of the public works in the future is there?
