几十年来，李裕民教授在史学研究领域勤奋耕耘，收获甚丰。《宋史新探》反映了他尊重科学、求新求真的精神。他对漆侠教授《宋代经济史》的批评及与漆教授弟子的论辩，成为当代史学史上引人注目的一桩公案。此事给人最大的启迪，是史学研究的繁荣有待于学术民主大环境的营造。 For decades, Professor Li Yumin has made great achievements in the field of historical studies. The new exploration of Song Shi reflects his spirit of respecting science and seeking truth from facts. His criticism of Professor Qi’s “Economic History of the Song Dynasty” and his argument with Professor Qi’s paintbrush became a notable public case in the history of contemporary history. This matter gives the greatest enlightenment is the prosperity of historical studies to be created in the academic and democratic environment.
