本文从经济发展、空间布局、产业特点、基础设施、用水排水、经济环境绩效等方面对长江经济带工业园区的发展进行了分析，基于此识别出园区绿色发展面临的挑战，并提出了园区深化绿色发展的建议。工业园区是长江流域承载制造业集聚的重要产业空间，是实施制造强国战略的主阵地，对沿江各省工业贡献大多超过50%，经济增长主力军和经济稳定压舱石作用显著，因此必须坚持工业园区作为制造强国战略主阵地不动摇。长江沿江工业集聚、园区密布，资源能源消耗及污染物排放量大。园区相关的生态环境问题突出表现为：部分地区的园区生态文明和绿色发展意识尚待提高，创新发展能力亟待强化；沿江工业园区布局及产业结构仍需深入优化，部分园区管理粗放，园区间绿色发展不平衡不充分明显；园区碳排放高，能源基础设施“大少小多”特征锁定碳排放；园区尚未有效控制用水总量及有毒有害污染物削减，水量水质水安全等问题尚未根本性解决。为此，建议从三个方面着力推进沿江园区创新绿色转型，打造长江生态文明建设新高地：一是加强顶层设计，上下游一体推进工业园区绿色发展，建立工业园区绿色发展报告制度；二是综合运用节约、提效、开源等措施深化园区绿色低碳转型，实施能源环境基础设施绿色化、低碳化改造，构建能源基础设施和环境基础设施间能源– 水产业共生体系，建设全生命周期绿色低碳园区；三是精准科学治污，从全过程推进园区水污染防治、水生态环境保护和可持续水管理，促进化工围江迈向人水和谐。

This study aims to uncover the paradigm of green development of industrial parks in the Yangtze River Economic Belt by integrating economic development, spatial configuration, pillar industries, energy-environmental infrastructure, water use, and economic-environmental performance. We identify the major challenges faced by the industrial parks in the region and then propose policy implications targeting eco-transformation of the parks. The key findings are as follows. Industrial parks have been playing a significant role in facilitating manufacturing industry and economic-social development in the Yangtze River Basin, by contributing more than 50% of the gross industrial output values of the provinces along the Yangtze River. It is necessary to strengthen the strategic position of the industrial parks for robust manufacturing industries in China. However, along the Yangtze River, there are large number heavy-industries and industrial parks, posing intensive pressure on resources and energy, as well as a huge pollutants emission. We classify four major points on ecological-environmental issues in the parks. First, some parks still need to enhance the initiative, consciousness and innovation of ecological civilization construction. Second, the parks should pose great importance on optimizing the industrial structure and environmental management of industrial parks, and declining the gap between leading parks and lowefficient ones substantially. Third, many parks have high carbon dioxide emissions, and have employed a coal-dependent energy infrastructure featured by small capacity and low efficiency. Fourth, industrial parks have yet to effectively control the total amount of freshwater consumption and reduce toxic and harmful pollutants reduction, pursuing clean and safe water. Given the challenges, we propose policy recommendations on innovation and eco-transformation of industrial parks from three aspects to achieve a marked height. The first aspect is to strengthen the grand plan for green development of industrial parks by integrating the upstream and downstream regions. The local authorities have the demand to release green development report annually. The second aspect is to deepen the green and low-carbon transformation of parks through conserving resources, increasing eco-efficiency, and exploring renewable resources comprehensively. Furthermore, it is crucial to advance the overall efficiency of energy and environmental infrastructure from the consideration of life cycle. Fostering industrial symbiosis between infrastructure is also a promising alternative. Third, it is urgent to balance the development of chemical industrial parks and the carrying capacity of water systems, by controlling pollution for the whole process using precise and scientific strategies, employing sustainable water stewardship, and protecting water eco-system.
