摘要：This paper explores the derivation mechanism of oblique object constructions in Mandarin Chinese. Based on the Morphological Fusion and the Minimize Exponence in Distributed Morphology, this paper proposes that the oblique object is assigned by the preposition and then the verb, which is intransitive, and the preposition undertakes morphological fusion. As a result, the verb is spelled out in the phonetic components and the oblique object occurs directly after the verb. We infer that “Ta chi shitang” (He eats in the canteen) and “Ta zai shitang chifan” (he eats in the canteen) have different generation mechanisms by exploring the different generation mechanisms of “Ta chi shitang” (He eats in the canteen) and “Ta zai shitang chifan”(he eats in the canteen). They cannot be converted from each other.
