基于三维投入产出表的生态产业链耦合分析

Coupling Analysis of Eco-industrial Chains at the Base of the Three-dimension PIOT

生态产业链是生态工业园区建设中的重要环节。本文结合天津经济技术开发区的汽车生态产业链,以物质流分析为框架,运用投入产出分析表对产业链进行耦合分析,建立了基于三维物质流投入产出表的产业链物质流分析模型,将产业链内部的物质代谢过程、结构特征、资源能源消耗数量及废物排放的状况细化、量化,为产业链条的构建、补链企业的引进提供有效的技术支持。

Eco-industrial chain is an important part in the building of the eco-Industrial park. On the basis of the MFA which is combined with the Auto Eco-Industrial Chains of TEDA of Tian Jin, this paper makes coupling analysis of the industrial chain by the PIOT, and builds the model of MFA of the industrial chain which is based on the three - dimension PIOT. The model specifies and quantifies the process of the material metabolizing, characteristic of the structure, consumption of the resource, and discharge of the waste in the industrial chain and offers technical support to the building of the eco-industrial chains and the introduction of the complementary enterprises.
