中文摘要:

      海洋新质生产力本质上是由海洋科技创新主导的先进生产力，对海洋经济高质量发展起到至关重要的作用。本文基于马克思主义生产力三要素理论，构建海洋新质生产力水平指标体系，以我国沿海11个省份的2007－2021年数据为样本，测度我国海洋新质生产力水平、区域差异及收敛性特征。结果显示，当前我国海洋新质生产力水平不高，整体上呈现平稳向上的趋势，东部海洋经济圈高于南、北部海洋经济圈；区域差异分析表明，我国海洋新质生产力水平的区域差异较为明显且处于波动起伏状态，差异主要来源于超密度贡献；收敛性分析表明，全国沿海整体及东部海洋经济圈存在σ收敛，且全国及东、北部海洋经济圈存在显著的绝对β收敛和条件β收敛，说明各地区海洋新质生产力差异会随着时间的推移收敛到各自的稳定状态。研究结论为分析海洋新质生产力时空格局提供依据，为构建现代海洋产业体系提供参考。

英文摘要:

      Marine new quality productivity is essentially advanced productivity led by marine science and technology innovation, which plays a crucial role in the high-quality development of marine economy. This article is based on the Marxist theory of the three elements of productivity and constructs an indicator system for the level of marine new quality productivity. The article uses data from 11 coastal provinces in China from 2007 to 2021 as samples to measure the level, regional differences, and convergence characteristics of China's marine new productivity.The results show that China's marine new quality productivity level is not high, and the overall trend is stable and upward, and the eastern ocean economic circle is higher than that of the southern and northern ocean economic circles. The regional difference analysis shows that the regional difference of China's marine new quality productivity level is more obvious and in a fluctuating state, and the difference mainly comes from the contribution of hyperdensity. Convergence analysis indicates that there are overall coastal and eastern marine economic circles in China σ Convergence, there is a significant absolute difference in the overall coastal and eastern and northern marine economic circles of the country β Convergence and conditions β convergence.This indicates that the differences in marine new material productivity in different regions will converge to their respective stable states over time. The conclusions of the study provide a basis for analysing the temporal and spatial patterns of marine new quality productivity and a reference for constructing a modern marine industrial system.
