日语连体助词“の”是日语学习者最先接触到的日语助词之一，贯穿整个日语学习及其使用过程。以汉语为母语的初级日语学习者到高级日语学习者，在学习连体助词“の”的过程中存在着大量的误用。迄今关于连体助词“の”的误用研究主要集中在「形容詞/形容動詞/動詞+の+名詞」的过多使用，如「*美しいの花」「*好きなの人」「*買ったの本」。少有研究「名詞1+の+名詞2」（如：*大正の時代）和「名詞1+名詞2」（如：*日本語勉強）这样的结构中连体助词“の”的过多使用和过少使用。本研究利用『YUKタグ付き中国語母語話者日本語学習者作文コーパス』分别讨论了中国人日语学习者在「名詞1+の+名詞2」和「名詞1+名詞2」结构中“の”的误用及其原因。通过考察发现，从名词1和名词2的语种组合的角度来看，学习者的误用主要出现在「漢語＋漢語」「漢語＋和語」「和語＋漢語」的语种组合中。最后，关于“の”过多使用和过少使用的产出机制，本论文认为引起误用的原因主要在于学习者对日语语法知识的认识不足以及受中文的语言习惯影响所致。

The Japanese conjoined particle “no” is one of the first Japanese particles that Japanese learners come into contact with, and it runs through the whole process of Japanese learning and its use. There are a lot of misuses in the process of learning the conjoined particle “no” from beginner Japanese learners who are native speakers of Chinese to advanced Japanese learners. So far, the research on the misuse of the conjoined particle “no” has mainly focused on the excessive use of "adjective/adjective/verb+no+noun", such as "*utukusii no hana", "*sukina no hito", "*katta no honn" . There are few studies on the excessive use of the conjoined particle “no” in the structure of "noun 1+no+noun 2" (eg: * daisei no zidai) and "noun 1+ noun 2" (eg: * nihonngo kyoushi). This article uses the corpus of"YUK Chinese native speakers of Japanese language learners corpus" to discuss the Misuse of Chinese Japanese learners in the structures of "noun 1 + no + noun 2" and "noun 1 + noun 2" . Through investigation, it is found that from the perspective of the language combination of Noun 1 and Noun 2, learners' misuse mainly occurs in the language combination of "Chinese + Chinese", "Chinese + Heyu", and "Heyu + Chinese".With regard to the production mechanism of "no" underused and overused, this paper argues that the cause of misuse is mainly due to the lack of understanding of Japanese grammar by learners and the influence of Chinese language habits.
