Constitutional Theory of Economic Freedom in the Post Welfare State Era.

本研究的目的是从宪政理论和法律的哲学的角度研究后福利国家的经济权利，并对日本宪法学者关于经济权利的学说进行批判性的反思。三是将经济法理论引入日本宪法经济权条款解释的尝试。这种尝试与“新自由主义”的放松管制政策有一定的关系。4.“宪法改革”政治话语中关于经济权利的思想和概念。关于主题1，我可以证明日本的宪法律师有充分的理由拒绝自由主义的财产概念。同时也发现，洛克的自然法理论不应该被理解为自由主义产权的正当性依据。在课题3中，我研究了日本日报的价格管制。有学者认为，这一规定具有反竞争性质，应该废除，但我明确指出，报纸在民主社会中具有重要作用，因此从宪法的角度来看，不能说竞争是这一规定最重要的价值。通过我的研究，我可以表明，即使在后福利国家时代，经济权利不可能是自由主义者所希望的准绝对权利，我们需要新民主主义的新概念来处理经济自由的管制和放松管制的问题。

The aim of this research is to study economic rights in the post welfare state from the perspective of constitutional theory and legal philosophy, and reconsider the doctrine of Japanese constitutional scholars about economic rights rather critically.According to this plan, I did some research and critical assessment on these topics below1.libertarian theory or vindication of economic rights.2.the theories of deliberative democracy and republicanism, which have some critical perspective on the protection of economic rights today.3.the attempt to introduce the economic law theory into the interpretation the articles of economic rights of Japanese constitutional law. That attempt has some relationship with "neo-liberal" deregulation policy.4.the idea and concept about economic rights in the political discourse of "Constitutional Reform".On topic 1, I could show that constitutional lawyers in Japan have good reason to reject the libertarian concept of property. And I also found out that natural law theory of John Locke should not be understood as the justification for the libertarian property rights.On topic 3, I studied the price regulation on the daily news paper in Japan. Some scholars say that this regulation should be abolished because of the anti-competition character, but I made it clear that news papers have important role in democratic society, so from the perspective of constitutional law, we could not say that competition is the most important value in that regulation.Through my research, I could show that, even in the post welfare state era, economic rights could not be quasi absolute rights that libertarian hope it to be, and we need new conception of new democracy that could manage the problem of regulation and deregulation of economic freedom.
