本文首先比较了我国各部门能源强度与世界其他国家和地区的差距，在此基础上设定提出了6种技术赶超情景，进而利用构建的多部门跨期动态优化MIDO模型，在产业结构调整和最优经济增长背景下分析了不同技术进步速度下我国的碳排放趋势。
this paper first compared the sectoral energy intensity between China and some major countries or regions，based on which we proposed 6 technology catch-up scenarios. With the assistance of MIDO（Multi-sector Inter-temporal Dynamic Optimization）model，we analyzed the CO2 emission trend under the framework of industrial structure evolution and optimal balance economic growth.
