The chlor-alkali/polyvinyl chloride production chain is characterized by high levels of energy consumption and emissions. The sustainable development of this industry has become a growing concern in the face of finite resources and the increasing demand. In the production chain, environmental, energy, and economic aspects are intricately linked. Thus, it's important to investigate how this industry can develop sustainably by examining the interactions among these three aspects. This paper evaluates the chlor-alkali/polyvinyl chloride production chain by using an integrated method combining the driving force-pressure-state-impact-response framework and system dynamics. First, the driving force-pressure-state-impact-response framework is used to investigate the interactions between society and the environment in the development of the production chain. Selected indicators were defined to characterize each subsystem in order to evaluate these interactions quantitatively. Next, system dynamics models are developed to explore the interactions among the three subsystems via causality loops. Five scenarios of the development of chlor-alkali/polyvinyl chloride production chain were simulated to see the effect of different policies on the subsystems. The results show that the sustainable development scenario showed reductions of 52% in energy intensity and 88% in chemical oxygen demand load intensity compared to business as usual. This integrated methodology can also be used as a decision-support tool for the design, planning, and management of the production chains of other process industries.

氯碱/聚氯乙烯生产链的特征是高水平的能源消耗和排放。面对有限的资源和不断增长的需求，该行业的可持续发展已成为人们日益关注的问题。在生产链中，环境，能源和经济方面错综复杂地联系在一起。因此，重要的是要通过研究这三个方面之间的相互作用来研究该行业如何可持续发展。本文采用驱动力-压力-状态-冲击-响应-响应框架与系统动力学相结合的综合方法对氯碱/聚氯乙烯生产链进行了评估。第一的，利用驱动力－压力－状态－影响－响应框架研究了生产链发展过程中社会与环境的相互作用。定义选定的指标来表征每个子系统，以便定量评估这些相互作用。接下来，开发系统动力学模型，以探讨因果关系循环在三个子系统之间的相互作用。模拟了氯碱/聚氯乙烯生产链发展的五个方案，以了解不同政策对子系统的影响。结果表明，与往常相比，可持续发展方案显示能源强度和化学需氧量负荷强度降低了52％。这种集成的方法还可以用作设计，规划，
