China is now considered a tech superpower in many areas. This book illustrates certain aspects and case studies of China's technological developments and further analyzes them under various areas like coal energy, housing, connectivity, digital and space technologies. Furthermore, it examines technological developments in the periphery of China, focusing especially on Hong Kong Special Administrative Region (HKSAR). This book does not pretend to be comprehensive in its coverage albeit surveys a spectrum of sectors in China and Hong Kong to get an idea of their developments. By peering into China through the mainland continental perspective and also looking into China from its periphery (e.g., "Greater China" perspectives from HKSAR), this book provides readers with the broad contours of technological development in China through a multidisciplinary area studies perspective.
