China has an estimated 120-150 million internal migrants from the countryside living in its cities. These people are the engine that has been driving China's high rate of economic growth. However, until recently, little or no attention has been given to the establishment of a social protection regime for migrant workers. This volume examines the key issues involved in establishing social protection for them, including a critical examination of deficiencies in existing arrangements and an in-depth study of proposals that have been offered for extending social security coverage. Featuring contributions from leading academics outside China who have written on the topic as well as experts from leading Chinese academic institutions such as Chinese Academy of Social Sciences and the Development Research Center in the State Council, this volume provides a comprehensive account from both inside and outside China.
