This book contains detailed documentation of the CHINAGEM model - a large-scale dynamic computable general equilibrium (CGE) model of China and its applications. Specifically, this book documents the theory and database behind the CHINAGEM model. This book explores the closure development for the four simulation modes of the model including historical, decomposition, forecast and policy simulations, the detailed explanation of how to analyze simulation results, and the extensions of CHINAGEM and their applications. These extensions include several innovative modules and case studies...
