This book explores four topics within the broad area of trade, industrial activity and the environment in China. Firstly, based on the hypothesis of pollution paradise, this book discusses whether China attracts pollution-intensive industries from developed countries because of its relatively loose environmental policies and becomes a "pollution paradise". Secondly, based on the demand and supply of environmental products, this book discusses the influencing factors of industrial pollution in China, and finds that energy consumption, human capital intensity, productivity and R&D investment are the most significant factors. The third and fourth topics respectively discuss the effects of industrial specialization and industrial spatial distribution on the concentration of pollutants. The results show that both of them have significant positive effects on the concentration of pollutants in specific areas of China.
