并列关系是人类思维最为基本的关系模式；并列类复句在汉语复句系统中占据重要地位。本文以元代汉语并列复句及相关问题为研究对象，通过对《元典章·刑部》《古本老乞大》《元刊杂剧三十种》《高丽史》《正统临戎录》等记录或模仿元代汉语口语、反映元代汉语口语面貌的语料进行描写和分析，构建元代汉语并列复句系统，探究其语义类型、语用功能、句法结构以及语言接触问题，探究汉语并列复句系统的历史演变特点与机制。全文共分为5章。

绪论首先说明选题意义与研究目标，界定研究对象元代汉语并列复句，并梳理前人研究成果，说明研究理论与研究方法。

第1章从分句并列项的语义逻辑关系出发，讨论元代汉语并列复句的语义类型，包括平列式、累加式、微转折式、微选择式、微递进式和微承接式等主要语义类型，以及递次式、回环式、譬喻式和解注式等其他语义类型，并分析其分布、转化与嵌套关系。

第2章从成分省略和形式对称的角度，讨论元代汉语并列复句的句法结构，包括主语、宾语和处置式的省略，以及不对称式、弱对称式、对称式和具有构式标记的强对称式，并分析其演变机制的经济原则与象似性原则。

第3章从关联标记的角度，进一步讨论元代汉语并列复句的句法结构，总结其语气、对称、嵌套等无标记形式，以及“也”类、“又”类等常见的关联标记，并讨论不同关联标记的发展特点。

第4章从语言接触的角度，讨论元代汉语口语及白话中的并列复句受文言书面语以及其他语言影响的结果，包括“p（有），q有”式、“p（者），q者”式、“V，V+‘的+补语’”式等特殊“复制构式”关联标记。

第5章为结论，总结全文对于元代汉语并列复句的语义类型、语用功能、句法结构以及语言接触问题的讨论，指出其历史演变的稳定性、渐变性、互动性与突变性特点，总结其演变机制，并说明本文的研究不足之处。

The coordinate relation is the most fundamental mode of human thinking; the coordinate complex sentences occupy an important position in the complex sentence system of Mandarin. This article focuses on the study of coordinate complex sentences and related issues in Mandarin in Yuan era by describing and analyzing language materials that record, imitate and reflect the spoken language such as Yuandianzhang Xingbu, Guben Laoqida, Yuankan Zaju Sanshizhong, Gaolishi, and Zhengtong Linronglu, constructing a system of coordinate complex sentences in Mandarin in Yuan era, exploring their semantic types, pragmatic functions, syntactic structures and language contact issues, and exploring the evolution characteristics and mechanisms of the coordinate complex sentence system of Mandarin. This article is divided into 6 chapters.

The introduction firstly explains the significance and research objectives of the topic, defines the research object of coordinate complex sentences in Mandarin in Yuan era, and summarizes previous research results, explaining the research theories and methods.

Chapter 1 discusses the semantic types of the coordinate complex sentences in Mandarin in Yuan era from the perspective of semantic logical relation of the clauses, including the main semantic types of parallel, cumulative, micro-transitional, micro-selective, micro-progressive, and micro-continuous, as well as other semantic types of sequential, circular, metaphorical, and annotated, analyzes their distribution, transformation, and nesting relation.

Chapter 2 discusses the syntactic structure of coordinate complex sentences in Mandarin in Yuan era on component omission including the omission of subjects, objects and disposal constructions, and on formal symmetry including asymmetric, weak symmetric, symmetric and strong symmetric forms with construction markers. It analyzes the principles of economy and iconicity as the mechanisms of evolution.

Chapter 3 further discusses the syntactic structure of coordinate complex sentences in Mandarin in Yuan era from the perspective of marker. It summarizes unmarked forms such as mood symmetry and nesting, and common markers such as “也” type and “又” type, and it discusses the development characteristics of different markers.

Chapter 4 discusses, from the perspective of language contact, the results of that classical Chinese and other languages have influenced the coordinate complex sentences in spoken and vernacular Mandarin in Yuan era, including the “replicated construction” markers such as “p (有), q (有)”, “p (者), q 者”, and “V, V+‘的+complement’”.

Chapter 5 is the conclusion, summarizing the discussions on the semantic types, pragmatic functions, syntactic structures, and language contact issues of the coordinate complex sentences in Mandarin in Yuan era. It concludes that their evolution is stable, gradual, interactive and abrupt, summarizes the mechanisms of the evolution, and explains the shortcomings of this study.
