20世纪李商隐诗学研究

20世纪唐诗学的研究中，对于晚唐诗人李商隐的研究成就突出。从生平事迹考订，到作品整理校注和思想艺术成就探讨，已取得许多重大的甚至是带有总结性的成果，并在不断开辟新的研究领域、研究课题。这深刻地反映了人们学观念的进步，也标志着人们对李商隐诗歌的认识在不断深入、不断提高。但是，李商隐研究也具有鲜明的时代色彩，其研究进程充满了曲折。大体上说，从20世纪初到五四运动前夕，是继承乾嘉以来笺注考证之学并加以发展总结的阶段；从五四到新中国成立前夕，是在现代域外新思潮和新化运动的影响下，呈现出新变的阶段；从新中国成立到20世纪未是在经历了一段时期的曲折以后掀起李商隐研究的第二个高潮，总结与创新并重的阶段。
