Book excerpt: The importance of foreign investment to China goes well beyond the USD 1.6 trillion in investment received since its opening. The unique analysis in this book shows that the investments, operations, and supply chains of foreign enterprises have accounted for roughly one-third of China’s GDP in recent years, and that foreign enterprises have made numerous additional contributions to China through technological, managerial, business practice, supply chain, and other spillovers. This book shows how China’s leaders managed this process and provides lessons for policy makers interested in building their own economies and tools for companies to demonstrate their contribution to host countries.
