本文以王安石的律詩作為切入點，嘗試從文體學的角度，並連繫唐宋詩歌演變的文學史背景，勾勒出北宋初年至神宗元豐年間律詩發展的軌跡。王安石不但有選擇性地吸取了宋初三體的部分特色，又進一步在詩歌內容、題材、藝術風格等方面進行開拓。大體來說，王安石的五律在繼承晚唐體的同時，又刻意迴避了其在內容和藝術上的種種缺陷；其七律在融合白體和晚唐體之餘，又融入了詠懷傳統和諷諭精神。故王安石在北宋律詩發展史上當具有承先啟後的地位和獨特貢獻。

From the perspective of stylistics, this paper explores the artistic expression of Wang Anshi’s 王安石 (1021-1086) regulated verse, which focuses on the different forms of the “three poetic styles” 宋初三體 in the Song dynasty. Wang not only selectively absorbed some of the characteristics of the “three poetic styles,” but also further expressed his own forms of development through the content, theme, artistic style, etc., of poetry. Broadly speaking, Wang’s five-character regulated verse 五言律詩 inherited the “later Tang style” 晚唐體, but simultaneously avoided its various faults concerning content and style. His seven-character regulated verse 七言律詩 both fused the “bai style” 白體 with the “later Tang style” and incorporated “singing of my feelings” 詠懷 tradition as well as an allegorical or a satirical spirit. Therefore, Wang Anshi, as a link between the past and future, uniquely contributed towards the development of Song poetry 宋詩.
