习近平总书记给四所交通大学全体师生回信，对学校发展提出殷切期望，强调“秉持‘求实学、务实业’办学宗旨”。通过对北京交通大学办学历史的考察可见，这一办学宗旨经历了从思想渊源、范式奠基、学科拓维到价值统合的演进，其核心内涵可概括为求真笃实的治学范式、经世致用的实践导向与知行合一的教育哲学。作为四所交通大学共同的精神底色，“求实学、务实业”办学宗旨贯穿交通大学百卅年办学历程。同时，也为我国高校扎根中国大地办世界一流大学和全球工程教育多元化发展提供了历史镜鉴与学理参照。

In his reply letter to the faculty and students of the four Jiaotong Universities， General Secretary Xi Jinping emphasized the need to adhere to the school‑running tenet of “Seek True Learning， Serve Practical Industry”， setting forth earnest expectations for the universities’ development. An examination of the educational history of Beijing Jiaotong University reveals that this tenet has undergone an evolutionary process spanning intellectual origins， paradigm establishment， disciplinary expansion and value integration. Its core connotations can be encapsulated as a truth‑seeking and pragmatic scholarly paradigm， a practice‑oriented ethos of applying knowledge to real‑world needs， and an educational philosophy premised on the unity of knowledge and action. As the shared spiritual underpinning of the four Jiaotong Universities， the tenet “Seek True Learning， Serve Practical Industry” has run through their 130‑year course of educational development. Furthermore， it provides historical insights and theoretical references for Chinese universities to develop world-class universities rooted in China’s national conditions and promote the diversified development of global engineering education， thereby boosting the construction of a leading country in education.
