基于空语类和论元结构，展示了汉语复合词“冒牌”从“论元填充”到“转喻关联”到“语域扩展”的完整功能扩展路径。从理论上看，“冒牌”的功能扩展沿“论元填充→转喻关联→语域扩展”的路径逐层推进，反映了词汇化程度逐步提高、空语类的可恢复性逐步降低的演化趋势。

Based on empty categories and argument structure, this paper demonstrates the complete functional extension path of the Chinese compound word “maopai” (counterfeit) from “argument filling” to “metonymic association” to “register extension.” Theoretically, the functional extension of “maopai” proceeds layer by layer along the path of “argument filling → metonymic association → register extension,” reflecting an evolutionary trend of a gradual increase in the degree of lexicalization and a gradual decrease in the recoverability of empty categories.
