Abstract This paper uses optimality theory (OT) to account for the phenomenon of identity occurrence resulting from clausal recursion, which we argue is derived from syntactic embedding and syntactic adjunction. This paper shows that the interaction between faithfulness and economy constraints allows for the optional deletion of functional morphemes that occur repetitively. The syntactic process of deletion is sensitive to the concept of markedness in a few ways. First, the marked, rather than the unmarked, pattern is the trigger for deletion; second, unmarked constructions have priority over marked constructions as the target for deletion. All of these ideas are integrated into the OT model that involves self-conjoined constraints, the mechanism of harmonic alignment, and the competition between faithfulness and economy constraints.

普通话中的标记关系、身份回避和分句递归

摘要 本文使用最优性理论（OT）来解释从句递归导致的同一性出现现象，我们认为这种现象源于句法嵌入和句法附加。本文表明，忠诚度和经济约束之间的相互作用允许选择性地删除重复出现的功能语素。删除的句法过程在几个方面对标记的概念很敏感。首先，标记而不是未标记的模式是删除的触发器；其次，未标记的结构优先于标记的结构作为删除目标。所有这些想法都被整合到 OT 模型中，该模型涉及自联合约束、谐波对齐机制以及忠实度和经济约束之间的竞争。
