中文摘要：

基于构式研究范式的基本观念，文章首先系统考察了变零构式（包括增零构式和减零构式）的生成机制及其语义增殖现象，并刻画了变零构式及其子构式的层级关系。接着以此为例来讨论修辞构式的增殖效应及与此相关的若干问题：增殖效应的基本内涵及其产生基础，增殖效应对构式生成机制的路径依赖，修辞构式的网络系统和创新层级，修辞构式增殖效应分析的方法论原则。以及从构式的增值效应角度重新审视修辞效果的构式属性。文章还论及了修辞构式的语言共性问题。

英文摘要：

Based on the constructional research paradigm, this paper first systematically investigates the generative mechanism and the semantic multiplication of changing fractional amount constructions, including the increasing fractional amount constructions and the decreasing fractional amount constructions. Then, it structures the hierarchy of changing fractional amount constructions and their sub-constructions. Taking changing fractional amount constructions as instance, the multiplication effect of rhetorical constructions and several related issues are discussed, such as the internal meaning and generative basis of multiplication effect, the path dependency on the constructional generative mechanism of multiplication effect, the network and innovation hierarchy of rhetorical constructions, the methodological principles of multiplication effect analysis in rhetorical constructions and the reexamination of the constructional property from the perspective of rhetorical effect. In the end, this paper discusses the language universals of rhetorical constructions.
