海洋经济视角下中国海洋科研网络研究——基于CiteSpace知识图谱分析

Marine Research Network From the Perspective of Marine Economy:Analysis of Knowledge Map Based on CiteSpace

海洋科学研究是海洋经济发展动能转换的核心动力源,推动海洋经济向高质量转变,而海洋科学研究合作网络发展是促进海洋科学研究大发展的重要一环。因此,以涉海机构发表的科研论文作为有效探究海洋科学研究合作能力的重要指标,借助CiteSpace软件分别对2007和2017年海洋科学研究的分布及机构合作网络特征进行分析。结果表明:①海洋科学研究发展迅速,研究领域更为多元化,研究热点与海洋经济发展的产业需求高度相关。水下海底矿床开采、海上油气田钻井工程、潜水技术与装置、水产机械仪器等是海洋科学研究的新兴或具有重点突破的领域,发文量的增长较为明显。②中国海洋科研合作网络的集聚性进一步增强,科研能力强的国字号科研院所及重点院校发挥着骨干作用。中国科学院的合作频数最高,作为海洋科学研究合作网络的"集线器"是海洋科学研究合作中最为活跃的节点。③在自然科学领域中,合作网络知识技术的"通道"更为稠密,由"单核心"的发散型结构发展为"多核心"的条带状伸展结构,研究内容聚焦于"船舶工程""水产养殖技术""海洋地质学"等方面。④在社会科学领域中,参与合作的机构增加,但相较于自然科学领域,尚未形成完整的科研合作网络。研究内容聚焦于"海洋经济""人海关系地域系统"等方面。最后提出优化合作网络的对策建议。

Marine scientific research is the core driving force for the transformation of marine economic development into a high-quality economy, and the development of marine scientific research cooperation network is an important part of the development of marine scientific research. Therefore, this paper takes the scientific research papers published by sea-related institutions as an important indicator of effective research cooperation capacity in marine science, and uses the CiteSpace software to analyze the situation of marine scientific research in 2007 and 2017 and the characteristics of agency cooperation network. The results show that: ① Marine scientific research is developing rapidly and the research fields are more diversified. The research hotspot is highly related to the industrial demand of the development of marine economy. The deep-water, oceangoing and new energy industries, such as mining of underwater seabed mineral deposits,drilling engineering of offshore oil and gas fields, diving technology and equipment,aquatic machinery and instruments, have become the rapidly growing research fields.②From the perspective of the whole cooperation network, there is a significant difference in the research capacity of ocean-related institutions in China. The Chinese Academy of Sciences(CAS), with the highest frequency, is the most active node in marine scientific research cooperation and the "hub" of the network.③In the field of natural science, the "channel" of knowledge and technology in the marine research cooperation network is more dense, from the "single-core" divergent structure to the "multi-core" strip extension structure, and the research content focuses on "ship engineering", "aquaculture technology", "marine geology" and other aspects. ④ In the field of social science, the number of institutions participating in the cooperation has increased, and the research content has focused on such aspects as "marine economy" and "human sea relationship regional system". However, compared with the field of natural science, a complete network of scientific research cooperation has not yet been formed.
