煤基多联产技术是先进清洁的煤炭利用技术，是综合解决我国能源系统主要问题的关键技术。针对我国多联产系统概念不清的现状，本文根据我国国情总结提炼出了多联产系统的定义及分类方法。同时，随着我国能源需求的不断增加，我国液态燃料供应紧张的问题日渐凸显，煤基液态燃料的发展势在必行，本文通过建立能源安全损益模型，得出了我国煤基替代燃料发展的最优规模。在此基础上，对我国多联产系统的发展潜力进行分析，提出了到2030年前我国煤基多联产系统的发展战略和技术路线。

The technology of coal-based poly-production, as the advanced coal-utilization technology, is the key way to solve China’s main problems on energy. Considering that China has not reached a joint conclusion about the concepts of co-production system, firstly this paper provided the method of defining and classifying co-production system based on China’s condition. With the increasing demand of China’s energy consumption, liquid fuel is gradually in shortage supply, so coal-based liquid fuel is on the way. Then, by building the energy security profit model, this paper also proposes the optimal scale of developing China’s coal-based alternative fuel. At last, based on the analysis of coal-based alternative fuel, the authors put forward the developing strategy and routine of co-production system till 2030.
