Abstract: | This paper explores the structure and the mechanisms involved in the formation of a hyperlink network of Guangzhou city's 118 homeowner forums in the context of a collective action by the homeowners. It develops a contextual analytical framework contending that the structure of the hyperlink network is influenced by utility values and utilization capability, as well as the media and social environments that shape these values, respectively. The results of the exponential random graph models support this framework. Specifically, hyperlinks are more likely to be created among neighborhood homeowner forums when the neighborhoods are located in the same administrative district, built by the same developers, and managed by the same property management companies. Unfavorable contexts that are prone to violent confrontation hamper the creation of cross-forum hyperlinks, but media visibility increases the odds of other forums hyperlinking to homeowner forums. In addition, high levels of online engagement are positively correlated with hyperlink formation. These findings suggest that although online platforms, such as homeowner forums, play a contributory role in collective action, they have limited power in fostering cross-neighborhood coalitions in urban China. |
