海洋新质生产力是新质生产力体系中尤为重要的一部分，其发展对推动海洋经济的高质量发展具有重要意义。基于熵值法测算中国沿海地区海洋新质生产力水平，结合标准差椭圆、核密度分析以及改进DEMATEL-ISM模型，分析2010—2021年中国海洋新质生产力发展水平时空演变特征并深入探讨其影响机理。结果表明：中国海洋新质生产力发展分布重心向西南方向移动，整体发展水平稳步提升，东部地区发展水平处于引领地位，南部与北部发展速度较快，且各区域均存在极化现象；海洋科研机构产出水平、数字市场活跃度及海洋数字创新能力为深层根源因素，单位GDP废水排放量、电信通信服务水平、海洋科研组织强度、沿海地区能源消费结构、营商环境指数为表层直接因素，并梳理出三条主要传导路径。在此基础上，从科技生产力、绿色生产力、数字生产力和开放生产力四个维度提出相关建议。

Marine new quality productivity is a particularly important part of the new quality productivity system, and its development is of great significance for promoting the high-quality development of the marine economy. Based on the Entropy Method and combining the standard deviation ellipse, kernel density analysis and the improved DEMATEL-ISM model, this paper measures the level of marine new quality productivity in China's coastal areas, analyzes the spatio-temporal evolution characteristics of China's marine new quality productivity development level in 2010-2021, and deeply explores its influencing mechanism. The results show that the distribution of China's marine new productivity development is moving towards the southwest, and the overall development level is steadily increasing, while the development level of the eastern region is in the leading position, the southern and northern regions are developing at a faster pace, and there is a polarization phenomenon in all regions. Another result is that the output level of marine scientific research institutions, the activity of the digital market and the marine digital innovation capacity are the deep root factors, while the wastewater emission per unit of GDP, the level of telecommunication services, the intensity of marine scientific research organizations, the energy consumption structure of the coastal areas, and the business environment index are the direct factors at the surface level, and three main transmission paths have been found. Finally, recommendations are made from four dimensions: technological productivity, green productivity, digital productivity, and open productivity.
