This book complies some of cooperative academic research papers by John Whalley, Yan Dong and Chunding Li. Most of these papers use applied general equilibrium modelling and simulation methodology to explore China's related international trade facts, difficulties and policies.John Whalley is a professor in the department of Economics of Western University (UWO) in Canada, and he is a pioneer in the applied general equilibrium calibration and simulation field. Yan Dong and Chunding Li both work in the Institute of Economics and Politics (IWEP), Chinese Academy of Social Science (CASS). From the year of 2008 to 2010, Yan Dong had ever worked in the Western University with John Whalley as a post-doctoral fellow. After that, Chunding Li had worked with John Whalley as a post-doctoral fellow from 2010 to 2012. During these periods of cooperative research, we used computational general equilibrium methodology to study China’s economic theory and policy in the fields of trade, climate change, imbalance, regional...
