This research is motivated by the proposition of the legitimacy of applying ¡§little theatre¡¨ as the mode of theatre management. The core context and the judgment of value of theater management today are founded basically on a ¡§large-scare theatre¡¨ paradigm; this causes, for most of the time, prejudice and insufficient result in managing theatrical affairs. To analyze the details of this problem, I started from rediscovering the ideological conflicts between Modernity and Post-Modernity, and tried to solve this dualistic misunderstanding by using ¡§Post-Modern Turn¡¨ as the mode of transcending. Since the term ¡§Post-Modern¡¨ is generally associated with social aspects as post-industry society, information society, organizational behaviors and consumption theory, etc. it is necessary to redefine theatre management as the issue of discussion in the realm of sociology. In order to approach my ideal strategy for today¡¦s theatre management, I developed three major parts as the frameworks of study: 1. the Post-Modern Turn of sociology of art, 2. five faces of modernization of Taiwan¡¦s modern theatre, 3. the Post-Modern Turn of organizational management and Taiwan modern theatre. I believe the difficulty of theatre management today lies not in the issue itself, but in the way we look at it. By relocating this problem in a social context, we can have a rethinking of how art management is possible, of exploring the updated and proper solutions for today¡¦s theatre management.
