中文摘要：文章基于中国沿海11个省份,首先从“要素结构”与“效益实现”视角构建评估指标体系,并运用博弈论组合赋权法测度了中国海洋新质生产力的发展水平;随后引入修正的引力模型测算海洋新质生产力空间关联强度,并借助社会网络分析法可视化其空间关联网络结构特征;最后基于扎根理论厘清海洋新质生产力空间关联网络的动力机制,并通过QAP回归法实证分析了其驱动因素。研究发现:①中国海洋新质生产力发展水平整体呈上升趋势,但仍有较大提升空间。②中国海洋新质生产力空间关联性和溢出效应显著,呈现复杂的空间网络结构特征。从整体空间关联网络特征看,关联性和稳定性不断增强;从个体网络特征看,东部海洋经济圈的上海长期处于网络中心地位,而北部及南部海洋经济圈多数区域处于边缘位置,但随着海洋经济发展边缘区域的地位逐步提升。③从网络角色和功能看,可划分为净受益、净溢出、经纪人和双向溢出4个板块,板块内部和板块之间均存在显著的溢出效应,且板块间溢出效应存在明显的梯度传递特征。④中国海洋新质生产力空间关联网络的形成主要受绿色技术进步差异、金融发展水平差异和地理空间邻近性等因素影响。

外文摘要：This paper constructs an evaluation index system of marine new quality productive forces from the perspectives of"factor structure"and"benefit realisation",and measures the development level of marine new quality productive forces of 1l coastal provincial-level regions in China using the game-theoretic combination empowerment method.It measures the spatial correlation strength of marine new quality productive forces by the means of a modified gravity model,and analyzes its spatial correlation network structure with the help of social network analysis.Based on the grounded theory,this paper clarifies the driving mechanism of the spatial correlation network of marine new quality productive forces,and empirically analyzes its driving factors by the QAP regression method.It's found that:1)The overall development level of China's marine new quality productive forces shows an upward trend,but there remains significant room for improvement.2)The spatial correlation and spillover effects of China's marine new quality there remains significant are significant,showing a complex spatial network structure.From the perspective of the overall spatial correlation network,both relevance and stability of the spatial correlation network have been continuously enhanced.From the perspective of the individual network characteristics,Shanghai in the eastern marine economic circle has been at the centre of the network for a long time,while most regions in the northern and southern marine economic circles occupy peripheral positions.However,with the development of the marine economy,the status of this peripheral regions has gradually improved.3)From the perspective of network roles and functions,it can be divided into four types:net benefit,net spillover,intermediation and two-way spillover.There are significant spillovers within and between types,and there are obvious gradient transmission characteristics of spillovers between types.4)The formation of spatial correlation networks of marine new quality productive forces in China is mainly influenced by differences in green technology progress,financial development levels,and geographical spatial proximity.
