While driving the regional economy, industrial parks also pose great threats to natural environment due to large quantities of resource consumption and intensive pollutants emissions. Eco-industrial development, including cleaner production, bioproducts or waste interchange, and infrastructure sharing, is key to improving the parks' environmental quality and sustainability. However, how to measure the performance of eco-industrial development is an essential and hard work since the material and energy flows are complex and cannot be compared in various units. The water and non-renewable resources which are very vital materials to sustain industrial activities in the industrial parks were rarely considered in the previous traditional ecological footprint analysis. Therefore, our research depicts a real picture of all the resources including water and non-renewable resources to illustrate the actual environmental impact of a national high technology industrial development zone-Jiangyin high technology Park, using energy based ecological footprint method. Results show that the emergy-ecological footprint deficit and emergy-ecological footprint intensity of the study park decreased by 16.75% and 16.74% due to the implementation of eco-industrial development. In detail, minerals made the largest reduction, 2.00E + 2 ha/capita, followed by fossil fuels with a reduction of 1.01E + 2 ha/capita, and the resources from cropland and pasture did not make a contribution in reducing emergy ecological footprint. Policy implications such as further replenishing and improving the ecological industry chains are proposed based on this survey. This study provides a basis to improve the environmental management and performance of industrial parks.
在推动区域经济发展的同时，工业园区也因大量资源消耗和密集污染物排放对自然环境构成了巨大威胁。生态工业发展，包括清洁生产、生物制品或废物交换以及基础设施共享，是提高园区环境质量和可持续性的关键。然而，由于物质和能量流复杂，无法在各个单位进行比较，因此衡量生态工业发展的绩效是一项必要且艰巨的工作。在以前的传统生态足迹分析中，很少考虑到水和不可再生资源等维持工业园区工业活动所需的重要物质。因此，我们使用基于能源的生态足迹方法，描绘了包括水和不可再生资源在内的所有资源的真实情况，以说明国家高新技术产业开发区——江阴高新技术产业开发区的实际环境影响。结果表明，由于实施了生态工业发展，研究园区的能值生态足迹亏缺和能值生态足迹强度分别减少了 16.75%和 16.74%。具体而言，矿产资源减少最多，为 2.00E+2 公顷/人，其次是化石燃料减少 1.01E+2 公顷/人，耕地和牧场资源对减少能值生态足迹没有贡献。根据这项调查，提出了进一步补充和完善生态产业链等政策建议。本研究为提高工业园区的环境管理和绩效提供了依据。
