The composition of Greater China among the PRC, Hong Kong and Taiwan entails an emerging form of micro governance where an ecological evolution of sub-group interaction and crossover of economic and social activities has been generating a dynamic of change within the East Asian region. The constitution of Greater China by social, economic, political, business and even daily commuting creates some soul searching questions about the possible outcomes of their intense interaction. To what extent has integration been made within Greater China through these interactions? Is China the economic linchpin or does China need to cooperate in one way or another to facilitate the modes of economic development? What are the attitudes and strategies used by Hong Kong or Taiwan when confronted with such an economic cum social entity? More importantly, where, and, under what conditions, will the interactions among the PRC, Taiwan and Hong Kong lead to? In this paper, I am going to use a conceptual model which includes four interactions: integration, interdependence, identity and independence (Four Is) to capture the catalyst of change that collectively entails these intermingled economic, social and cultural elements. People who live in the vast context of this geographical region experience the change. Through daily interaction, they help write the context of change through business activities, investment, migration, trade, culture, academic exchange, political and social development along the Four Is.
