人類的「傳播」(communication)活動，正與人類的歷史同樣的古老，無論其傳播的意向或工具是否顯著，實際影響卻一直存在於人類的社會生活中。透過傳播的過程，藉之而瞭解他人，反之，致力為他人所瞭解。因此，本文採取一個觀點：傳播活動是人類生活的一個中心點，傳播活動(含接受活動)也正是促進文學發展與進步的重要動力。本研究嘗試以現代的傳播概念，從既有之文獻資料進行分析解釋，並從不同的傳播層面(level)與模式(mode)，來探討宋儒楊時對程門洛學南移所從事的傳活動，一則探究其主要的傳播內容與傳播效果，另則希望見出傳播者楊時在當時洛學網絡建立中的關鍵地位。本研究結果除了可說明傳播活動對人類生活所產生的實際影響外，在結合文學與傳播的學術思考上也可供後續相關之參考。

Human communication activity is as old as human history. Whether the intentions or instruments of communication activity were obvious or not, the actual influence of communication activity has existed in the social life of human beings. Through the process of communication, communicators have used communication activity to understand other people; otherwise, the communicators tried to use communication activity to be understood by others. Therefore, this research takes the following point of view: communication activity is one center in the life of human beings; communication activity (including receiving activity) is also the major force for promoting development and progress in literature.
