摘要
1936年12月12日晨，張學良、楊虎城發動兵變，劫持正在西安的行政院院長兼軍事委員會委員長蔣中正，是爲「西安事變」。事變由發生之初的劍拔弩張，至最終能和平解決，充滿著戲劇性，其中的關鍵人物之一，爲蔣夫人宋美齡的兄長，曾任國民政府行政院副院長兼財政部長之宋子文。 宋子文於12月19日自南京啟程，20日抵達西安，瞭解情況，停留一日即轉返南京；22日，陪同宋美齡再度赴西安，與張學良、楊虎城及中共代表周恩來等周旋，取得各方面同意，事變和平解決，於日陪同蔣中正及宋美齡離開西安，經洛陽，26日返抵南京。關於宋子文處理西安事變善後，促使事變和平解決一事，以往學者已有專文討論，而在西安事變相關專著中，亦占有相當篇幅。但是大多數的研究係將宋子文與宋美齡放在一起討論，以「宋氏兄妹」稱之，不過在《蔣中正總統檔案》、《宋子文檔案》等資料相繼公開之後，宋子文在事變解決過程中所發揮的作用與角色更加凸顯，宜有重新檢討與單獨討論之必要。本文基本上是運用近年來所公布之新資料，特別是蔣中正在西安事變期間的日記與宋子文之西安事變日記，進行討論，希望對於他在西安事變和平解決過程中所起的作用有更進一步的認識。

In the morning of December 12, 1936, Chiang Kai-shek was held hostage by Chang Hsueh-liang and Yang Hu-cheng in Sian. It is so-called the ”Sian Incident.” T. V. Soong, the elder brother of Madam Chiang, was one of critical persons who helped conclude the incident peacefully. One week after the incident broke out, T. V. Soong left Nanking and arrived in Sian on December 20. For only one day he had got at the whole situation. Then he returned to Nanking. On December 22 he flew again to Sian, together with Madam Chiang, and began to negotiate with Chang Hsueh-liang, Yang Hu-cheng and the Communist representative Chou En-lai. They reached an agreement. On December 25 Chiang Kai-shek, Madam Chiang and T. V. Soong left Sian. They arrived in Nanking on the following day. There are numerous previous researches on the Sian Incident. Some of them deal with the roles of Madam Chiang and T. V. Soong's in peaceful settlement. My paper probes deeply into the ”Chiang Kai-shek Collection” and the ”T. V. Soong's diary of the Sian Incident” and finds that T. V. Soong contributed greatly to the solution of the Sian Incident. His personal role in the negotiation should not be neglected.
