郝经作为蒙元初期的北方大儒，推本经学而深造自得，以学济用而贵于大成，不拘小用，从而在元初学术、政治、文学领域都有所成就。“天风海涛”是郝经临终前所书写的遗言，其中所蕴含的意味是极其复杂的，其中不仅蕴含了郝经博大充沛的理学气象，也暗含了其奔走南北、波澜起伏的一生。故而本文以“天风海涛”为主题，分五个章节，参照郝经自身对于学术次第的理解，对郝经的生平、思想及文学研究进行研究，重新发覆郝经的政治活动、学术思想与文学观念在元初南北分裂之际的独特价值。

第一章是立足郝经生平活动对其思想形成过程的探讨，实际上是此后章节进一步深入研究的基础。首先，对郝经受召前的思想形成过程进行了研究。通过对郝经家学渊源相关文献的梳理，重新解释了郝经自述家学次第的之所以可信的原因，以及这种家学次第所体现的真正内涵。其次，自郝经受召起，至其使宋受囚真州为止，通过梳理郝经在忽必烈幕府中的活动及思想变化，从而对郝经在金莲川幕府中的地位与作用进行了重估。最后，本章对郝经真州所作的《使宋文移》的分析，对其在真州生活以及心境的变化进行了描绘，通过对其真州著述的详细考证，发解了郝经真州著述的真意所在。

第二章是对郝经学术思想的研究。首先，本章对郝经经学、理学体系的发微的基础上，探讨了郝经有用之学的根基所在。郝经对于五经次第有清晰的认知，经学统摄了他对其他门类学术的理解与建构，而他立足经学对理学诸概念的阐释，实际上是其“有用之学”的基础所在。其次，在郝经的经学体系内部，《易》可谓枢机之学，不明《易》理，难晓其学。故而本文依照郝经对易学所分象数、著述、事业三端，对郝经的易学思想体系进行阐释。郝经立足《系辞》《说卦》《序卦》等十翼文本，对《太极图》《先天图》进行了阐释，不仅意在构建两图的经学根基，也以两图为基础构建了自身理学体系的根基。郝经以《周易》卦象经传文本为核心，不仅将易学的终极旨趣归结于对太极密理的研求、体悟及施用层面，也将后世易学散乱纷纭的状态纳入了这种高度结构化的易学体系之中，引《易》立说、用《易》作论，从而真正意义上建构了他“《易》为明理之书”的观念。最后，作为研究郝经“有用之学”的一个案例，本文从郝经易学观念中抽绎出“几”的概念，通过对历代“几”说的分析，对郝经易学中“几”的观念进行源流分析，从而探究易学如何影响郝经对于天下大道的体认，而郝经对于“几”的体认实际上影响了他对时局大势的判断，并最终决定了他对于出处之道的选择。

第三章是对郝经“天官学”实践与思想的系统性研究。首先，本文对郝经生平的三次观星记录进行了分析，探究了天官学对于郝经生平活动的真正影响，阐释了每次观星记录中所蕴含的郝经对于南北局势的认知。其次，对郝经《续后汉书·历象录》《玉衡贞观》，以及《玉衡贞观》中的《变异事应》进行了成书研究，对郝经天官学的知识构成进行了阐释。最后，立足郝经的家学渊源以及理学体系，对郝经的天官学的起源、意蕴和致用进行了探讨，揭示了郝经以“王道政治”为准则的天官学知识系统，与金末元初主占候或测验风气的差异。

第四章是将郝经的历史观念与政治观念相结合的研究。首先，本章研究了郝经如何通过《续后汉书》的编纂进行正统性建构，以及他如何通过对分裂历史的重新思考，尝试为自身所处的分裂时代寻找出路。其次，本章对郝经的夷夏观、正统论进行了研究。在郝经的观念自始至终中都有“夷夏”观念的存在，而且对“夷夏”概念的理解、阐释与运用，在郝经正统性构建过程中有着重要的作用。最后，本章对郝经《便宜新政》中的建言与中统初年的备战和制度创建的关系进行了探讨。

第五章是对郝经文学观念、创作及交游的研究。首先，本章立足郝经的经学、理学体系，对文学观念进行三方面的探讨。郝经的文统观念表面上看是“非文”，实际上却是“非伪”，即批判华辞绮句遮蔽下的情伪怪谲，反对不知操行践履而空谈辞藻的辞章之学，而其理学诗、咏史诗亦皆为“言之有物”“以道为依”之作。其次，本章对郝经的和陶诗进行了研究。郝经《和陶诗》所构造的“桃花源”具有浓厚的理学气象，他所追求的也并非仅仅是陶渊明式的对生命本真的持守，而以“理”和陶，将陶诗中原有的本真朴素之韵与理学的精微宏大之气相结合，最终构造出辞本性情、气法颜曾、思通天人的精神桃花源——“吾庐”。最后，本章对郝经与金元之际的文坛宗匠元好问的交游情况进行了考论，探讨了郝经与元好问在文学、学术层面的异同。从他们的交往中不仅够观察到旧学与新学的碰撞与隔阂，亦能窥见金末元初金源文人与理学新士交游之一斑。

As a great Confucian scholar in the north of the early Yuan Dynasty, Hao Jing has profound attainments in the study of Confucian classics, he can apply what he has learned, not just for trivial purposes. So he made achievements in the fields of scholarship, politics and literature in the early Yuan Dynasty.  “Sky Winds and Ocean Billows” is a last words written by Hao Jing before his death，the meaning contained in it is extremely complicated, which not only contains a broad and abundant Neo-Confucianism atmosphere, but also implies Hao Jing's life of running north and south and ups and downs. Therefore, with “Sky Winds and Ocean Billows” as the theme, this paper is divided into five chapters. With reference to Hao Jing's own understanding of academic order, this paper studies Hao Jing's life, thought and literature, rewrite the unique value of Hao Jing's political activities, academic thoughts and literary concepts at the time of the split between the north and the south in the early Yuan Dynasty.

The first chapter is based on the discussion of the formation process of Hao Jing's thought based on Hao Jing's life activities, which is actually the basis of further in-depth study in the following chapters. First of all, it studies the formation process of Hao's thought before he was summoned. By combing the relevant literature on the origin of Hao Jing's family tradition, this paper reexplains the reason why Hao Jing's self-description of family tradition is credible, as well as the real connotation embodied in this kind of family tradition. Secondly, from the time Hao Jing was summoned to the time when he was imprisoned in Zhenzhou by Southern Song Dynasty, by combing the activities and ideological changes of Hao Jing in the Kublai’s council, restudy the status and role of Hao Jing in the Jinlianchuan council. Finally, this chapter analyzes the diplomatic documents he wrote to the Southern Song Dynasty in Zhenzhou, describes his life in Zhenzhou and the changes of his mood, and through the detailed textual research of his Zhenzhou works, explains the true meaning of Hao Jing Zhenzhou's works.

The second chapter is the study of Hao Jing's academic thought. First of all, on the basis of the development of the study of Hao Jing's Confucian classics and Neo-Confucianism, discusses the foundation of the “useful study” of Hao Jing. Hao Jing has a clear understanding of the Five Classics, which dominates his understanding and construction of other kinds of learning, and his interpretati on of the concepts of Neo-Confucianism based on the study of Confucian classics, which is actually the basis of his concept of "useful study". Secondly, In the system of Hao Jing's study of Confucian classics, the study of Yi is the core of his academic thought. Based on the Ten-wings texts such as XiCi, ShuoGua and XuGu, Hao Jing explains “Tai ji Diagram” and " Xiantian Tu", which is intended not only to construct the foundation of Confucian classics, but also to construct the foundation of his own Neo-Confucianism system. Taking the divinatory images in the Yi as the core, Hao Jing not only attributed the ultimate purport of Yi study to the research, understanding and application of Taiji theory, but also brought the chaotic state of Yi study into this highly structured Yi study system, introducing the theory of "Yi" and using the theory of "Yi", so as to construct his idea that "Yi" is the book of reason. Finally, as a case study of Hao Jing's "useful study", this paper deduces the concept of "Ji" from Hao Jing's concept of Yi. Through the analysis of the theory of "Ji" in previous dynasties, this paper analyzes the origin of the concept of "Ji" in Hao Jing's study of Yi. Thus, it explores how the study of Yi affects Hao Jing's understanding of the Dao of the world, and Hao Jing's understanding of "Ji" actually affects his judgment of the world, and finally decided his political choices.

The third chapter is a systematic study of the practice and thought of Hao Jing’s astrology. First of all, this paper analyzes the three stargazing records of Hao Jing, explores the real influence of astrology on Hao Jing's life activities, and explains Hao Jing's cognition of the situation in the north and south contained in each stargazing record. Secondly, it makes a book research on Li Xiang Lu and Yu Heng Zhen Guan and Bian Yi Shi Ying, explains the knowledge composition of Hao Jing's astrology study. Finally, based on the family origin and Neo-Confucianism system of Hao Jing’s astrology, this paper probes into the origin, implication and application of Hao Jing's astrology, and reveals Hao Jing's astrology knowledge system is based on the principle of "King's way Politics".

The fourth chapter is the study of the combination of Hao Jing's historical concept and political concept. First of all, this chapter studies how Hao Jing carries on the orthodox construction through the compilation of Xu Hou Han Shu, and how he tries to find a way out for his own era of division by rethinking the separatist history. Secondly, this chapter studies the “Yi Xia” view and orthodoxy of Hao Jing. There always have the concept of "Yi Xia" in Hao Jing's mind, and the understanding, interpretation and application of the concept of "Yi Xia" plays an important role in the process of his orthodox construction. Finally, this chapter discusses the relationship between the suggestions in Hao Jing's political advices and the preparation for war and the establishment of the system in the early years of the Qubilai qaan.

The fifth chapter is the study of Hao Jing's literary concept, creation and social relationship. First of all, this chapter discusses the concept of literature in three aspects based on the study of Confucian classics and Neo-Confucianism of Hao Jing. On the surface, Hao Jing's concept of literary tradition is "non-literary", but in fact it is "non-false", that is, criticizing the false and treacherous feelings under the cover of words, and opposing the study of meaningless words. And his Neo-Confucianism poems and epic poems are also works of "taking Tao as the basis". Secondly, this chapter studies the poems Poetry in Reply to Tao Yuanming of Hao Jing. "The Peach Blossom Garden" constructed by Hao Jing and Tao Poems has a strong Neo-Confucianism atmosphere, and what he pursues is not only Tao Yuanming's adherence to the truth of life, but also reason and Tao. Combine the original simple rhyme in Tao Yuanming's poetry with the subtle and magnificent spirit of Neo-Confucianism, and finally construct his own " Peach Blossom Garden"-"My Home". Finally, this chapter makes a textual research on the friendship between Hao Jing and Yuan Haowen, a master of the literary world during the Jin and Yuan dynasties, and discusses the similarities and differences between Hao Jing and Yuan Haowen at the literary and academic. From their communication, we can not only observe the collision and estrangement between the old era and the new era, but also see the friendship between the literati and the new scholars of Neo-Confucianism at the end of Jin Dynasty and the beginning of Yuan Dynasty.
