摘要
深海科技作为国家战略前沿与全球科技竞争的重要领域,其关键技术群落的识别与竞争态势分析对把握创新方向、优化资源配置具有重要意义。基于全球深海科技领域74752项专利数据,构建技术相对影响力(RIT)指标识别强势、新兴、衰退与沉睡四类技术态势,并采用Louvain社群发现算法识别出深海科技关键技术群落,进一步通过核心专利筛选与t-SNE降维可视化算法,绘制国际竞争态势图谱,系统揭示主要国家在深海科技关键领域的优势分布与竞争格局。研究表明:(1)深海科技整体处于快速演进与技术迭代阶段,在数字信息传输、电子器件及高分子耐腐蚀材料等方向创新活跃;(2)深海科技领域包括15个关键技术群落,涵盖海洋药物、耐腐蚀材料、储能技术、智能探测、深远海养殖装置等多个方向;(3)中国在深海科技领域专利总量处于领先地位,但核心专利占比低,尤其在基础材料与能源系统方面与美国、日本存在显著差距。本研究为深海科技领域的创新布局与国际竞争策略提供数据支撑与决策参考。
Deep-sea technology,as a critical frontier of national strategy and an important arena of global technological competition,makes the identification of key technology clusters and the analysis of competitive landscapes highly significant for guiding innovation directions and optimizing resource allocation.Based on a global dataset of 74,752 patents in the field of deep-sea technology,this study constructs a Relative Influence of Technology(RIT)index to classify technologies into four categories:dominant,emerging,declining,and dormant.Using the Louvain community detection algorithm,key technology clusters in deep-sea technology are identified.Furthermore,through core patent screening and visualization based on t-SNE dimensionality reduction,an international competitive landscape map is constructed to systematically reveal the distribution of advantages and competitive patterns among major countries in key areas of deep-sea technology.The results show that:(1)deepsea technology as a whole is in a stage of rapid evolution and technological iteration,with particularly active innovation in areas such as digital information transmission,electrical devices,and high-molecular corrosion-resistant materials;(2)the field comprises 15 key technology clusters,covering multiple directions including marine pharmaceuticals,corrosion-resistant materials,energy storage technologies,intelligent detection,and deep-and far-sea aquaculture equipment;and(3)although China ranks first in terms of the total number of patents in deep-sea technology,its share of core patents remains relatively low,with significant gaps compared to the United States and Japan,especially in foundational materials and energy systems.This study provides data support and decision-making references for innovation layout and international competition strategies in the field of deep-sea technology.
