海洋强国与创新驱动发展战略下，组织间协同创新合作成为突破海洋新兴产业关键核心技术“瓶颈”的重要模式。中国海洋战略性新兴产业在各类海洋政策引导下实现快速发展，然而在发展过程中仍存在尖锐问题，特别是产学研之间技术创新协同的割裂以及缺乏有效的横向与纵向协同创新机制，鉴于此，本文使用联合申请专利数据从协同创新角度构建产业技术创新的无向加权网络，利用网络可视化和ERGM方法深入分析该网络的拓扑结构、空间分布特征及其驱动机制。研究结果表明：（1）在海洋政策引导下，企业成为技术创新协同网络的核心力量，协同主体主要分布在环渤海地区、长江三角洲和珠江三角洲；（2）内部驱动机制中，中心性和传递性成为关键的内部驱动因子，技术创新协同网络的形成和发展依赖于核心主体的聚类效应和传递性机制的促进作用；（3）外部驱动机制中，地理距离影响协同倾向，同类组织协同提高效率，跨制度协同具有互补性，文化差异对协同网络影响减弱。在现有政策下，产业技术创新现状与驱动机制因素的分析，也将为推动海洋战略性新兴产业高质量发展和相关政策制定提供实践启示。

   In the context of maritime power and innovation-driven development strategy, inter-organizational cooperative innovation has become a crucial model for overcoming the key technological bottlenecks in emerging marine industries. Under various marine policies, China′s strategic emerging marine industries have experienced rapid development. However, sharp issues persist throughout their development process, particularly the fragmentation between academia, industry and research in technological innovation, and lack of effective horizontal and vertical cooperative innovation mechanisms. In response, this paper constructed an undirected weighted network of industrial technological innovation from a cooperative innovation perspective using the joint patent data. The network′s topology, spatial distribution, and driving mechanisms are analyzed in depth using network visualization and the ERGM method. The study found that: (1) under the guidance of marine policies, enterprises emerge as the central force in the technological innovation network, with key collaborating entities primarily located in the Bohai Rim area, the Yangtze River Delta, and the Pearl River Delta. (2) Analysis of the internal driving mechanisms of network formation indicated that centrality and transitivity are key internal drivers. The formation and development of the technological innovation cooperation network rely on the clustering effect of core entities and the facilitative role of transitivity mechanisms. (3) Among external driving mechanisms, geographical distance affects collaborative tendencies; collaboration among similar types of organizations enhances efficiency; cross-institutional collaboration offers complementarity; and the impact of cultural differences on the cooperative network is diminishing. The analysis of the current state of industrial technological innovation and driving mechanism factors under existing policies will also provide practical insights for promoting high-quality development of marine strategic emerging industries and the formulation of related policies.
