In this context, energy-environment models designed for analysis of energy systems have become more important. In this paper, a Computable General Equilibrium Model （CGE） using an energy-environmental version of Global Trade Analysis Project （GTAP） model （known as GTAP-E） for Vietnam is presented based on the GTAP Data Base version 7. The model is developed following the original structure and the revised version of the GTAP-E model. This model is used to simulate the adoption of carbon tax for Vietnam for the base year of 2004. The economy-level and detailed sector-specific effects are also examined considering energy intensive and non-intensive sectors. Simulation results show the negative influences of different carbon tax scenarios to Vietnam＇s economy. The results would also indicate the potential of carbon taxation as a driving force for the mitigation of carbon dioxide and for new and renewable energy promotion in Vietnam. In fact, this study is the first simulation exercise of energy-environmental policy for the Vietnamese case.展开更多

The objective of this study is to examine the impacts of alternative policies on China and World economy after canceling MFA. Based on a general equilibrium model of the Global Trade Analysis Project (GTAP), study shows that China and World will significantly benefit from further trade liberalization. However, if USA, EU and Canada converted to TBT to restrict import, the gains from eliminating MFA would be largely offset. Based on our analysis, some policy implications are discussed.展开更多
