Chemical industrial parks have led to the concentration of major hazards which can potentially result in a domino effect of accident losses. Environmental risks need to be managed in a cost-effective way for chemical industrial parks. This paper focuses on the applicability of the environmental pollution liability insurance (EPLI) in park-wide risk management. The interactions among stakeholders (i.e., chemical companies, insurance companies, and the local government) are investigated using system dynamics (SD). The SD model for EPLI considers the interactions between output value, risk level, related government policies, and insurance products. Three different insurance scenarios are developed, i.e., single company, multiple coalitions, and grand coalition. SD is used to comprehensively map the causality relationships among stakeholders and simulate trends over time. A practical case study is used to illustrate the model. Results show that the implementation of coalition EPLI helps reduce management difficulties and result in lower premiums in the long run when implemented. Furthermore, the most beneficial strategy is insuring the entire coalition of industries.

化学工业园区导致主要危害的集中，这有可能导致事故损失的多米诺骨牌效应。对于化学工业园区，必须以具有成本效益的方式管理环境风险。本文着重于环境污染责任保险（EPLI）在整个公园范围的风险管理中的适用性。使用系统动力学（SD）研究利益相关者（即化学公司，保险公司和地方政府）之间的互动。EPLI的SD模型考虑了产值，风险水平，相关政府政策和保险产品之间的相互作用。开发了三种不同的保险方案，即一家公司，多个联盟和一个大联盟。SD用于全面映射涉众之间的因果关系并模拟一段时间内的趋势。实际案例研究用于说明该模型。结果表明，实施EPLI联盟有助于降低管理难度，并从长远来看降低保费。此外，最有利的策略是确保整个产业联盟。
