Industrial symbiosis (IS) is an important tool to achieve green development for industrial parks. It is necessary to evaluate the IS performance for monitoring and managing the development of IS system. This study proposed an integrated framework to assess the IS performance based on the energy-intensive industrial park. Firstly, we established a Conceptual model of symbiotic coupling of three industries (iron and steel, thermal power, and cement). Then, the conceptual model was applied to extend the existing IS system in the energy-intensive industrial park. Finally, the IS performance of the extended IS system was evaluated. We verified this framework in Red flag cannel park (RFCP). The IS performance assessment in RFCP found that the existing IS activities produced significant multiple benefits and environmental impact reduction. For example, the existing IS activities produced 970.20 kt of low-carbon benefits, which accounted for 19% of the CO emissions in RFCP. However, after extending the existing symbiotic system combined with the conceptual model proposed in this study, we found that there still was a large amount of symbiotic potential (the reuse of waste heat, BF slag, gypsum) waiting to be developed in RFCP. In addition, we also found that the resilience of existing IS network in RFCP was weak and need to be further perfected. In general, in the further development and perfection of IS system in RFCP, the manager should not only focus on the development of IS activities among energy-intensive enterprises but also strive to foster more influential enterprises to enhance the anti-risk ability of IS network. The result indicates the integrated framework can provide support for the development and perfection of IS system in energy-intensive industrial parks.
产业共生（IS）是实现工业园区绿色发展的重要工具。评估产业共生绩效对于监测和管理产业共生系统的发展很有必要。本研究提出了一个基于能源密集型工业园区评估产业共生绩效的综合框架。首先，我们建立了三个产业（钢铁、火电和水泥）共生耦合的概念模型。然后，将该概念模型应用于扩展能源密集型工业园区现有的产业共生系统。最后，对扩展后的产业共生系统的绩效进行了评估。我们在红旗渠园区（RFCP）验证了这个框架。RFCP的产业共生绩效评估发现，现有的产业共生活动产生了显著的多重效益并减少了环境影响。例如，现有的产业共生活动产生了970.20千吨的低碳效益，占RFCP碳排放的19%。然而，在结合本研究提出的概念模型扩展现有共生系统后，我们发现RFCP仍有大量的共生潜力（余热、高炉矿渣、石膏的再利用）有待开发。此外，我们还发现RFCP现有产业共生网络的弹性较弱，需要进一步完善。总体而言，在RFCP产业共生系统的进一步发展和完善中，管理者不仅应关注能源密集型企业间产业共生活动的发展，还应努力培育更具影响力的企业，以增强产业共生网络的抗风险能力。结果表明，该综合框架可为能源密集型工业园区产业共生系统的发展和完善提供支持。
