China's transformation from a poor and underdeveloped country into a global market power has profoundly altered its socioeconomic power relations with the other countries in the Greater China region, namely, Taiwan and Hong Kong. Indeed, this economic shift has resulted in the massive flow of capital and people from Taiwan as well as Hong Kong to China, to seek business opportunities and new lifestyles. These flows have in turn completely transformed longstanding borderlines in the region. This book examines the transformation of Taiwan and Hong Kong's socioeconomic relationships with China as their economies have become more deeply integrated into Greater China. Across three key sections, it explores the impact of increasing social interaction and the shrinking of existing borderlines to ask whether these changes will bring about a convergence of identity among the people involved."Production" examines how investments from Taiwan and Hong Kong to China have transformed production networks; "Community" explores the impact of cross-boundary mobility and the integration of migrants into Chinese communities; and finally, "Identity" engages with what is one of the most important issues in contemporary Taiwanese society. Border Crossing in Greater China contributes not only to theoretical debates on border crossing issues, but also provides valuable insights on the practical concerns regarding social and political integration and tensions in the region. As such, it will be of great interest to students and scholars of Taiwan studies, Chinese studies, Chinese society and Chinese economics.
