Migrant workers are an inevitable issue that has accompanied China's socioeconomic transformation, and has a direct bearing on the country's social and economic progress, and stability. This book aims to present a comprehensive picture of China's issue of migrant workers that has emerged during its urbanization. Breaking away from the conventional research methodology, this book examines the trend of China's migrant workers as a social and economic phenomenon, teases out its pattern, proposes the establishment of a social support system for migrant workers in light of China's socialist market economy, and provides a solid theoretical fulcrum for China's central government to develop its macroeconomic policy.
