随着海洋数据的持续积累与资产化,其对沿海城市海洋产业集聚的影响日益显现。构建海洋数据资产驱动下的沿海城市—海洋产业空间集聚模型,从理论上探讨海洋数据资产影响沿海城市海洋产业集聚的作用机制,并利用2000—2024 年中国54 个沿海城市的面板数据进行实证检验。研究发现,海洋数据资产对沿海城市海洋产业集聚具有显著的正向影响。机制分析表明,海洋数据资产通过降低海洋信息成本、促进海洋技术创新和推动海洋人力资本积累三条路径显著提升沿海城市海洋产业集聚水平。从产业层面看,海洋数据资产对沿海城市海洋第一产业和第二产业集聚具有显著的促进作用,但对海洋第三产业集聚水平的影响不显著。从海域层面看,海洋数据资产对海洋产业集聚的促进作用主要体现在渤海和东海沿岸城市。基于研究结论提出政策建议,以期为中国式现代化背景下的海洋经济实践提供参考与借鉴。
As marine data accumulates and becomes an asset, it has profoundly influenced the clustering of marine industries in coastal cities. Based on a spatial agglomeration model linking coastal cities and marine industries—driven by marine data assets— this study theoretically explores the mechanisms through which marine data assets influence industrial agglomeration. It further con- ducts an empirical analysis using panel data from 54 Chinese coastal cities （2000 - 2024） to examine the differential impacts of marine data assets on this agglomeration. The results reveal that marine data assets exert a significant positive effect on the agglomera- tion of marine industries in coastal cities. Mechanism analysis indicates that these assets boost agglomeration levels by reducing marine information costs, fostering marine technological innovation, and enhancing the accumulation of marine human capital. At the sectoral level, marine data assets promote the agglomeration of primary and secondary marine industries but have no significant impact on the tertiary marine industry. At the regional sea level, the significant impact of marine data assets on marine industry agglomeration is observed only in coastal cities bordering the East China Sea and the Bohai Sea.
