基于CiteSpace的国内二语习得研究热点及演化趋势分析(1993-2019)

Research Hotspots and Evolution Trend of Second Language Acquisition in China Based on Cite Space(1993-2019)

论文采用文献计量学方法,以CNKI数据库中CSSCI和中文核心期刊中所刊的2 612篇关于二语习得研究论文为数据来源,通过对27年来二语习得领域的研究范畴进行关键词共现、聚类分析、关键词时区图等可视化研究发现,二语习得研究的视角不断扩大,已经展现出了与神经系统科学、神经生物学等自然科学融合的趋势,主要集中在基于认知的语言迁移、词汇习得,动态系统理论和转换生成语法等;从2007年开始,国内的第二语言习得研究呈现出迅猛发展的态势,每年平均发文量为161篇,当前的研究热点包括三语习得、二语加工、事件相关电位(ERP)技术的应用等;二语习得与其他学科领域的合作呈现出不均衡的发展态势,如社会文化视角的研究还不够丰富且分散。

This paper uses bibliometrics to visually analyze the categories in the field of second language acquisition in the past 27 years, with 1,891 papers on second language acquisition published by CSSCI and core journals in CNKI database as data sources. With Cite Space5.1 software keywords co-occurrence, clustering analysis and keyword time zone map visualization operation, the study finds that the perspective of second language acquisition research is constantly expanding and has shown a trend of integration with neuroscience, neurobiology and other natural sciences, mainly focusing on cognition-based language transfer, vocabulary acquisition, dynamic system theory, universal grammar, etc. Since 2007, second language acquisition research in China has been in the stage of rapid development, with an average of 122 articles published every year. Current research hotspots include third language acquisition, corpus research, second language processing, event-related potential(ERP), etc. The cooperation between second language acquisition and other disciplines shows an unbalanced development trend, for example, studies from sociocultural perspectives are not rich and scattered.
