Abstract: Ecological civilization construction demonstration zones (eco-industrial parks) (hereinafter referred to as Demonstration Zones) are key drivers in the formation of new quality productivity′s geographical patterns. Grasping their evolutionary laws is crucial for optimizing resource allocation and deepening green and low-carbon development of parks. Taking the 44 officially named demonstration zones in the Yangtze River Delta (YRD) region as the research objects, based on clarifying the development process of the construction of demonstration zones from 2007 to 2022, this study systematically analyzed the overall spatial pattern, aggregation morphology evolution, spatial directional migration characteristics, and influencing factors of demonstration zones in three development stages. The results show that: (1) The development process of the demonstration zones exhibited distinct stage-specific features. (2) The spatial distribution of demonstration zones was clustered, yet overall balance has been enhanced. The clustering morphologies evolved from three aggregation centers of "one main center and two sub-centers" to a "one belt with multiple points" spatial pattern centered around Suzhou, Wuxi, Changzhou and Shanghai. The distribution range showed a trend of moving towards the northern and southern ends and a westward bias, with the main distribution trend having a high degree of consistency with the route of the Grand Canal. (3) Optimal parameter identification can significantly enhance the scientific nature of the combined classification and strengthen the interpretability of influencing factors. The industrial and economic base, economic power and the government investment efforts were the core factors affecting the spatial distribution of the demonstration zones, followed by environmental protection infrastructure investment, scientific research and innovation investment, scientific and technology level and human resources investment. It is suggested that full attention should be paid to the promotional effects of the influencing factors, the strengthen of the driving role of demonstration, the deepening of the practice of ecological civilization construction, and the drivening of high-quality development.
