Politics, bureaucracy, and social security in the years of high economic growth.

这项研究着眼于战后日本社会保障制度发展中的重要角色。其中一位是日本农业合作社，另一位是民主社会党。在这项研究中，我认为江淮汽车没有利用其政治影响力来发展国家养老金制度，因为他们已经有了自己的私人养老金制度，这可能受到了公共养老金的阻碍。我还讨论了日本社会民主思想的形成过程，DSP采用了这种思想作为其意识形态，重点是一直是DSP的大脑的关关义彦。

This study look at the roles of the important actors in the devlopment of social security system in post-war Japan. One actor is the Japan Agricultural Cooperatives, JAC, and another is the Democratic Socialist Party, DSP. In this study I argued that JAC had not used its political influence for the development of the National Pension System because they have had their own private pension system which may have been hampered by the public pension. I also discussed the process of thought formation of social democracy in Japan that DSP had adopted as its ideology, putting emphasis on Yoshihiko Seki who had been a brain for the DSP.
