Public Investment as a Social Policy in Remote Rural Areas in Japan

Abstract

This paper aims to summarize the mechanisms of public investment as a social policy in remote rural areas in Japan. It includes findings from former studies as well as a case study undertaken in Shimane by the author, and it discusses the function of public investment in terms of the relationship between the three major groupings involved in the local civil engineering industry. These groups are the primary labor force group (PLG) which consists of workers born before or in 1935, the secondary labor force group (SLG) which consists of workers born after 1935, and the local civil engineering companies (LCECs). In the 1970s and 1980s, there was a strong mutual dependence between the PLG and the LCECs in remote rural areas. PLG workers gave higher priority to maintaining a traditional rural lifestyle and hoped to find jobs in their local area, hence jobs for them should have been created through public works projects. The LCECs also wanted a cheap and quantitatively flexible labor force for public works projects, so public investment worked effectively as a regional social policy. However, as the PLG workers retired and a new generation of workers entered the work force, the disparity between the supply of and demand for labor in the civil engineering industry has increased and the role of public investment as a social policy has been weakened. These changes suggest that the so-called kaso problem is generation-specific and that public investment as a social policy for remote rural areas is nearing its end
