[영문]Literature examining political framing generally focuses on the way that shared framing leads to cohesive actions and policy outcomes. Using a case study of San Francisco's homeless policy field, this article shows that shared framings among the majority of actors in the policy field did not lead to cooperative alliance among those actors nor to coherent policy based on their shared framing. To understand why shared framing failed, I examine the complex interaction between frames, influence, and material resources. While the center and the left of the policy field shared common diagnostic framings and solution-oriented prognostic framings of homelessness, the right possessed far superior material resources and political influence compared to the left. The center and left divided over different tactical prognostic framings about how to politically relate to the resources and influence of the right. These internal dynamics of the field were further amplified by the field's local institutional and national policy-making contexts. This article adds to understandings of how to map political fields, how ideas shape policy outcomes, and how meaning and materiality interact in the process of politics.
