政策アドボカシーにおける政治理論と実証分析の競合と協働

―都市とモビリティをめぐる諸問題を事例として―

My argument is that both political theory and empirical research can make a positive contribution to the practice of policy advocacy although these two disciplines have different ways to approach it. In this paper, I argue this by taking a case study about controversies over the urban transport planning in the United States. I take an example of political theory as the normative analysis given by Paul M. Weyrich (1942-2008) who is a staunch supporter of the public transportation system including street car in America. One of the points I try to make is that when Weyrich takes action as an advocate for public transportation, he sometimes shows us his argumentation as if it is a narrative discourse which may trigger emotions causing the support for street cars. In addition to this, I argue that his argumentation needs to respond to the evidence that empirical researches can provide if it claims the validity of policy advocacy.
