Based on the institutional theories of property development, the market entry model is conceptualized in this article as a construct of social relation network and applied to analyze cross-border investments in industrial property services across the Taiwan Strait. It explores the interactive relations between structural environment and actors of industrial property. Nevertheless, due to the influences of the regional political environment caused by the tension between Taiwan and China, the states become a significant factor for cross-border investment strategy and market entry model of property service firms from Taiwan. It is argued that cross-border social networks and local entrepreneurial governments in China are the major components for the market entry model of Taiwan's investment in China's industrial property services.
