国内句法复杂度的研究现状——基于CiteSpace的知识图谱分析
A Review of Syntactic Complexity Research in China—Knowledge Graph Analysis Based on CiteSpace

句法复杂度是反映和衡量学习者二语书面语和口语产出水平发展的重要标准，对于二语学习者以及二语教学具有重要意义。本文通过CiteSpace文献计量工具对中国知网(CNKI) 2009~2023年国内句法复杂度研究文献进行知识图谱分析。研究发现，句法复杂度的研究在国内尚处于发展时期，对于句法复杂度的研究主要分为四类。第一，各变量对句法复杂度的影响。第二，探究产出作品的句法复杂特征。第三，对比英语学习者和英语母语者的句法复杂度。第四，探究写作质量与句法复杂度的关系。
Syntactic complexity is an important criterion to reflect and measure the development of second language learners’ written and oral output levels, which is of great significance to second language learners and second language teaching. This paper uses CiteSpace bibliometric tool to analyze the knowledge graph of China National Knowledge Network (CNKI) literature on syntactic complexity from 2009 to 2023. It is found that the research on syntactic complexity is still in the development stage in China, and the research on syntactic complexity is mainly divided into four categories. First, exploring the influence of factors on syntactic complexity. Second, exploring the syntactic complex features of the output works. Third, comparing the syntactic complexity of English learners and native English speakers. Fourth, exploring the relationship between writing quality and syntactic complexity.
