Incidental vocabulary acquisition (IVA) plays a vital part in the field of L2 acquisition. It is critical for scholars to know comprehensively about the research status and hotspots of IVA in the future. This paper applies CiteSpace software to visually analyze 616 articles from CNKI. It turns out that: (1) There is a lack of cooperation from author to author, and from institution to institution. Meanwhile, the cooperation between authors is better than that between institutions; (2) The hot topics in this field are divided into six parts: involvement load, reading, influencing factors, glossing, vocabulary teaching and empirical study; (3) The development of IVA in China is roughly divided into three stages: the infancy period, the rapid growth period and the stable development period.
