东北亚地区的能源基础设施合作引起了很多学者的关注.大多数研究专注于该地区电网互联、可再生能源开发的技术可行性,而忽略了能源基础设施合作带来的社会和经济效益的定量分析.本研究使用可计算一般均衡模型来评估构建东北亚能源互联网的经济社会效益.主要模型工作包括 1)构建新的嵌套结构,2)通过计量模型估计化石和非化石能源发电替代弹性,3)设定基准情景,4)制定东北亚能源互联网政策情景.模型结果表明,东北亚地区将受益于能源互联网建设,地区生产总值之和高于基准情景.但同时能源互联网建设的大量投资将部分降低该地区的消费.此外,文章还展示了能源互联网建设对不同经济部门以及地区环境的影响.“,”There has been an intense discussion on the energy infrastructure cooperation in Northeast Asia.Most studies have focused on the technical feasibility of grid interconnection,deployment of renewable energy,and have ignored the quantitative analysis of social and economic benefits of these proposals.This study uses a computable general equilibrium model to evaluate the effects of energy interconnection in Northeast Asia.Key model development tasks include 1)constructing a new nesting structure,2)econometrically estimating the constant elasticities of substitution(CES)between fossil-and non-fossil-power generation bundles,3)developing a new base-case scenario,and 4)developing the policy scenario.We found that while Northeast Asia will benefit from energy interconnection development with higher GDP than in the base-case; there will be a trade-off between higher investment and lower consumption.Sector results and environmental implications in this region are also discussed.
