本論文由李庭《寓庵集》詩詞著手，藉由李庭作品瞭解詩人在金代亡國後侍奉異朝的心境即其仕與隱之間的轉變，進一步由詩詞中瞭解金末元初社會景況，探討其由仕到隱的轉變。全文先論述研究動機、研究主題。再以「儒與道」為主題，藉由史書所載及與友人唱和之詩歌內容瞭解李庭人格特質，其中有對國君及人民的忠貞之心、重視儒術的傳承，及對歸隱山林嚮往的多重變化。再由李庭思想的轉變著眼，分為「期望救國的儒家思想」時期：此時詩歌的主旨思想為「期勉立功沙場之士」、「期望國家重視正直之士」、「期望國君應當自省」三方面。後因金朝危亡轉而有「侍奉異朝的入世心態」：此時主要期望將自己經世濟民的能力運用在百姓之中。最後在歷經金、元、宋三朝的巨變，而有「避世的隱士思想」：此時期主要探討其隱居因素在「仕宦辛苦－有馬有馬他人騎」、「古今興亡之感－萬法本空人自擾」。從本論文中可以瞭解，在國家危亡之際，文人在尋求對歷史負責、對國家、國君、及百姓忠貞等外在名節之時，心境上的轉變，最終李庭仍是選擇追求自我心靈的平靜。在歷史的洪流之中，如果可以以更寬容的角度看待詩人的選擇，也可以使自我心靈得到更寬闊的自在。

This research focused on the poet Li Ting's Collection "The Poetry of the Recluse Life". From Li Ting's work realized, as the Chin Period had been destroyed, he served on a strange country as an official in a different status, a change between governmental life and retired from the service. Further, I explored his poems found the society situation in the end of the Chin Period and at the beginning of the Yuan Dynasty. First of all, this research dealt with the motivation and theme, secondly the thought system of "Confucian School and Tao School" by the history material and conversed in songs and verses in details, found out Li Ting's character and personality, for example faith in his country and people, respected to the succession of Confucian thoughts, retired from the world and brought a recluse life. Starting on the varying of his thought, divided into three phases: I read "an Expect of the Confucian thought to save his country and folk" found three aspects: "established merits by the soldiers on the battlefield was an encouragement", "the authorities had expect to the honesty superiors and had confidence in the honesty superiors", as well as "expected to higher officials reflected themselves faithfully. Due to the Chin Dynasty in danger, he came to an idea of" serving on the strange government", he expected to work and benefit people well. As a result, he experienced through Chin Period, Yuan and Sung-Dynasty dramatically, initiated on a retirement life. I investigated his retirement reason of "He served as an official and as if a horse controlled by a rider, just described the difficult governmental life" as well as "A status between ancient and modern time noted countless principles would be vanished." From this research would be examined that the nation was endangered, the superiors sought his duty of fame and upright of the external world to the history, to his county, to his authorities, to his people faithfully. Li Ting's option of a mind free from worries and cares by himself would be read was his essential change. In the history main stream, Li Ting's alternative, gained a tolerant vision of open and wide.
