宋代地方長官通常設有四司：轉運使、提點刑獄、提舉舉平及安撫使。當中以轉運使最為重要，蓋其可影響吏治之清濁，民生之富貧、國庫之盈虛、邊防之振弱，以至藩鎮之消長。因之，宋代轉運使成為重要之研究課題，惟就其建置年份、原因及員額三方面而言，似尚可深入探討。又論者有謂轉運使職掌無一得專，蓋以其受制於其他監司。但宋人所指監司，只指轉運使、提點刑獄及提舉常平三種。而提點刑獄初屬運司管轄，後腳出運司而獨立，但往往廢置不常，職事常由轉運使兼領，官位亦在漕使之下；至於提舉常平，成為監司行列，在神宗熙甯八年後，雖在神宗重用下，權力可與轉運使及提刑相比，但畢竟職權範圍有限，官位更比提刑為低。觀此，轉運使何以受制於其他監司? 此一問題，似值得深入探討。本文就為探討轉運使之建置年份、原因、員額及其在路制中之地位與其對宋代政治之影響而作。

　　　　　In the Sung Dynasty, there were three levels of local administration, the highest level being the provinces (Lu路). There were four heads in each province, namely, the Zhuan Yun Shi (轉運使), T i Dian Xing Yu (提點刑獄), Ti Ju Chang Ping (提舉常平), and the An Fu Shi (安撫使). Among these, the zhuan Yun Shi was the most important. Finance, local administration, military matter and legal affairs were entirely under the Zhuan Yun Shi's control. For this reason the Zhuan Yun Shi could have a great influence on the quality of management of lacal government officials, living standard of the citizens, treasury situation and national defence matters. It is thus worthwhile to look into the issue of the Zhuan Yun shi system. Some scholars said the the Zhuan Yun Shi had not regular power and was under the control of other Jian Si. In fact, the duty of the Ti Dian Xing Yu was taken over by the Zhuan Yun Shi because of the continual abolishment of the Ti Dian Xing Yu. Owing to the fact that the emperor (Shen Zong) put the Ti Ju Chang Ping in an important position, its power could be compared with the Zhuan Yun Shi's and Ti Dian Xing Yu's. But its power lasted for only a short time. Furthermore, the political position of Ti Dian Xing Yu and Ti Ju Chang Ping was inferior to the zhuan Yun Shi. So, how could the Zhuan Yun Shi be put under the control of the Ti Xing and Ti Chang? Thus, this paper discusses the establishment of the Zhuan Yun Shi and its political position and influence under the Lu system in the Sung Dynasty.
