The study is focused on the 1997 port reform planning in Kaohsiung Harbor that implemented the rationalization of recruiting system and privatization of terminal operation. Its influence on local labors and labor union was analyzed. Port reform is a global phenomenon in the 90s. The main content includes the deregulation and privatization. By conducting the in-depth interview and literature analysis the researcher noticed that port reform did not achieve the anticipated efficiency and competitiveness. It not only harms the working condition of labors, but also destroys the Dockers' union that has been existed for fifty years. The result embodies the capital system of global shipping industry; the national normative design has suppressed the labor system, worsened the competition of local industry and provided the international capitalists the possibility of pillage.
