从文献计量的视角,深入分析我国风险评估研究领域近20年的研究内容、方法及趋势。以CNKI期刊数据库1997-2017年发布的风险评估领域相关文献为研究对象,按发文量划分为三个阶段,通过关键词共现分析、社会网络分析及数据可视化等方法,总结风险评估研究的潜在热点和发展趋势。通过词频统计及网络分析发现信用风险、食品安全、环境风险及信息安全,是风险评估的主要研究内容。模糊综合评估和层次分析法是应用频次最多的方法,但随着时代需求的变化和数据收集与存储技术的发展,一些基于大数据和深度学习的方法,在风险评估研究中的受关注程度得到提升。

From the perspective of bibliometric to analysis deeply the research content, methods and trends in the field of risk assessment in recent 20 years. Taking the relevant literature of risk assessment published by CNKI journal from 1997 to 2017 as the research object, this paper divides the literature into three stages according to the amount of articles published, through the methods of keyword co-occurrence analysis, social network analysis and data visualization, the potential hot spots and development trend of risk assessment research are summarized. Through the word frequency statistics and network analysis found that credit risk, food safety, environmental risk and information security, is the main research contents of risk assessment. Fuzzy comprehensive evaluation and analytic hierarchy process are the most frequently used methods. However, with the changing in demand of the eras and the improvement of data collection and storage technologies, some methods based on big data and deep learning, have been receiving more and more attention in risk assessment research.
