基于海洋新质生产力的内涵和主要特征，测算2010—2022年中国11个沿海省份的新质生产力水平，并分析新质生产力水平的区域差异及动态演变特征，结果显示：(1)在研究期内，中国海洋新质生产力整体上发展水平不高，但呈现上升趋势。(2)新质生产力水平存在显著的区域异质性特征，东部地区内部的新质生产力水平差异大于北部、南部地区，东部和南部，以及北部和南部的地区间差异是导致中国新质生产力水平差距扩大的主要原因。(3)全国总体及三大海洋经济圈海洋新质生产力发展均存在差距且差距呈现不断扩大趋势，海洋新质生产力发展水平存在集聚效应；省际间海洋新质生产力发展具有明显的空间溢出效应，且追赶效应与拉动效应并存。(4)根据海洋新质生产力均值高低及发展类型权衡，将11个沿海省份划分为“海洋科技振兴型”“海洋基础提升型”发展模式，以期为各省份因地制宜发展海洋新质生产力、助力海洋强国建设提供新思路。

Based on the connotation and main characteristics of marine new quality productivity, this paper calculates the level of new quality productivity in China′s 11 coastal provinces from 2010 to 2022, and analyzes the regional differences and dynamic evolution characteristics of the level of new quality productivity. The results show that:(1) During the study period, the overall development level of China′s marine new quality productivity is not high, but it shows an upward trend.(2) There are significant regional heterogeneous characteristics in the level of new quality productivity. The difference in the level of new quality productivity within the eastern region is greater than that in the northern and southern regions. The difference between the eastern and southern regions and the northern and southern regions is the main reason for the widening gap in the level of new quality productivity in China.(3) There are gaps in the development of new marine productivity in overall China and the three major marine economic circles, and there is an agglomeration effect in the development level of new marine productivity. The development of inter-provincial marine new quality productivity has obvious spatial spillover effect, and the catch-up effect and pull effect coexist.(4) According to the trade-off between the average value of new marine productivity and the type of development, this paper divides 11 coastal cities into two development models: one is "marine science and technology revitalization", and the other "marine infrastructure improvement", in order to provide new ideas for the development of marine new productivity and the construction of a marine power in a targeted manner.
