Abstract: To identify the means and driving force for pollution control, and assess the performance, the pros and features of Eco-industrial Park (EIP) construction, a new index system is established to evaluate the retrospective effects of the emission control performance of an EIP, and is applied successfully in a case study of Rizhao Economy Technology Development Zone EIP (RZEIP). Results show that during the ten-year span from 2003 to 2012, (1) the performance of the emission control in Rizhao EIP shows a feature of obvious different phases following the pattern of increasing, reducing and increasing; (2) throughout the construction and development, the economic development is found to have a “relative decoupling” relationship with the total emission of the pollutants. The industrial added value was increased by 10.6 times, while the emissions of COD, ammonia and SO2 were reduced by 54.2％, 28.4％ and 81％, respectively; (3) the performance reflects the typical characteristics of EIP and cleaner production, industrial symbiosis and infrastructure sharing are the main way of sustainable emission reduction; (4) compared to the national level, RZEIP represents faster economic growth, better total emission and intensity control.
