Abstract
In Japan, the problem of large companies depriving small and medium-sized firms of production value (exploitation problem) has long been pointed out as a source of exhaustion for small and medium-sized firms in various industries, including the construction and civil engineering industries. In this study, we measured the purchasing attitudes of purchasing managers of large firms, who are the actual participants in the exploitation problem, and analyzed the relationship with the personalities and moralities that exist in the background. As a result, it became clear that authoritarian organizations and anti-social personalities of purchasing managers decreased consideration for suppliers. In addition, when authoritarian organizations and purchasing managers have weak anti-social personalities, there is a possibility that there is a structure in which, while consideration for suppliers increases, compliance with company manuals and heightened awareness of cost improvement promotes exploitation was shown.
