工业生态学的发展使公司管理者越来越多地考虑公司在区域系统中的利基，并制定优化计划。我们使用能值为基础的，生态经济综合评价两个优化方案的九发热电联产（CHP）厂，山东中国。并对系统进行了经济投入产出分析和能量分析。研究结果表明，即使企业自身没有进行技术优化，将具有暂时性超额生产力的企业适当纳入其区域系统，也有助于企业整体生产力的最大化，提高生态经济效率和社会效益。此外，在公司与其区域系统之间建立更密切的关系将有助于开发新的优化机会。与大型化石燃料和可再生能源系统相比，小型燃煤热电联产系统的能源效率较低，环境负荷较高，可持续性较低。能值交换率是评价高度发达的生态经济系统活力的重要指标。
The development of industrial ecology has led company managers to increasingly consider their company's niche in the regional system, and to develop optimization plans. We used emergy-based, ecological-economic synthesis to evaluate two optimization plans for the Jiufa Combined Heat and Power (CHP) Plant, Shandong China. In addition, we performed economic input–output analysis and energy analysis on the system. The results showed that appropriately incorporating a firm with temporary extra productivity into its regional system will help maximize the total productivity and improve ecological-economic efficiency and benefits to society, even without technical optimization of the firm itself. In addition, developing a closer relationship between a company and its regional system will facilitate the development of new optimization opportunities. Small coal-based CHP plants have lower-energy efficiency, higher environmental loading, and lower sustainability than large fossil fuel and renewable energy-based systems. The emergy exchange ratio (EER) proved to be an important index for evaluating the vitality of highly developed ecological-economic systems.
