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 trade agreement negotiations, and etc. In memory of these joint research times ,we choose some representative and important works to compile this book, and hope it can benefit you in learning applied general equilibrium modeling and simulation methodology as well as understanding China’s international trade situations.

　　Applied general equilibrium modeling and simulation methodology is one of main research technique and instrument in economics. The distinguishing characteristic of the general equilibrium approach is a focus on economy-wide resource allocation. This focus has made the approach a highly attractive vehicle for economic planning and policy analysis. The papers in this book provide a representative selection of applications of general equilibrium modeling to economic policy analysis. Therefore this book will be helpful for learning computational general equilibrium research technology, and meanwhile valuable for understanding the development of the general equilibrium modeling and application.

　　Research topics of selected papers in this book are mainly in international trade, including trade and climate change, trade policy bargaining, trade disputes, trade imbalance and mega-regional trade agreement. Most of these3 topics set China as the research target or as examples. Therefore these papers are conducive to understand both presently important international trade issues and China’s foreign trade policy.

　　We select 13 papers in this book, all of them had already published in academic journals including the World Economy, Economic Modelling, China Economic Review, Journal of Policy Modelling, Applied Economics, and etc. The former 7 papers are all cooperative works by Yan Dong and John Whalley, and the latter 6 papers are mainly cooperative works by Chunding Li and John Whalley.

　　All papers in this book are representative of recent experience in empirical as well as theoretical analysis. We wish to express our hope that this book may contribute to the understanding of CGE modeling and application.
