This study analyzes market mechanism including causes of the limited market extent on focusing in consumption pattern of performing arts. We find that performing arts consumption is social network dependent. Specifically, consumption of performing arts is sensitively responding to information environment of consumers. Information contagion plays a major part in collective consumption of performing arts. Trust as a decision rule of consumption is a building block of network dependency. Futhermore we advance that network dependent consumption causes unequal distribution of demand through self-organizing endogenous dynamics. Interestingly, the strong ties of the network`s members reinforce unequal distribution and restrict total market size of performing arts industry. This implies that building and development of diverse networks contributes to the growth of this industry.
