宋《易》的復古與開創，約而言之，有幾點：一是宋人注經強調新義，貴有所得， 意在自成「一家之言」，這是宋代經學變古獨創之因。二是時代精神的確立，宋《易》大體的走向是「一掃虛无」， 以明聖人之旨。即以儒家的實理及兩漢象數學掃王弼道家《易》的虛無，強調人事的作用。這是對魏晉以來偏差學風的檢討，也標示著時代風氣的轉變。新觀念、新思維逐步建立、風行。而一掃虛无是強調用《易》的價值，即《易》不僅能學，還要能用，否則變成空言立說， 無補人世。三是類型的開拓，宋《易》對義理、象數的研究，各有著重發明，且取得一定的成果。四是作文體的注經新形式的產生， 以義理思想的發揮為主， 取代經書字句的訓詁。以上大抵是宋《易》在精神、型態與體製上的修正創新，並對後世影響深遠。

Simply speaking, the origination of Yijing in Song Dynasty contains four meanings: First, people in Song Dynasty emphasized innovation and valued creativeness, i.e. to establish its own style, and this is the reason why the literature in Song Dyna sty became an original creation in the ancient times. Second, to establish the spirit of the time; Yijing trended to eliminate the vanity, in order to clarify the instruction of saints. It used the essence of Confucianism and the knowledge of Xiangshu (Ima ges and numbers) to eliminate the vanity of Wang Bi’s Taoism, thus to emp hasize the functio n of person and action. It reviewed the bias style of study emerging from Wei and Jin dynasties and marked a transformation of the spirit of the time. New concepts a nd new thoughts radually formed and prevailed. “To eliminate the vanity” emphasized the value of “change”, i.e. we should not only learn to change, b ut also should learn to use what has been changed; otherwise, it will be of no use and do nothing good to the world. Third, to develop categories; Yijing made much contribution to the study of philosophical connotations and Xiangshu, and made great successes. Fourth, there appeared new writing forms which mainly educated through idealistic aspect instead of me aning explanation of words and sentences. The above are the general innovations of Yijing in the aspects of spirit, form and system.
