[目的/意義]學習借鑒國外發展情報學的創新發展成功經驗,推動具有中國特色的情報學研究健康發展及理論體系建設。[方法/過程]運用歷史追溯和對比分析的方法,對近50年來發展情報學理論與應用的歷史概況和主要領域研究進展進行了全面歸納總結。[結果/結論]認為與西方經典情報學相比,發展情報學的研究成果已在學科重點問題設定、理論體系基本假設修正和理論與實踐緊密結合三個方面取得創新突破,在很大程度上拓展了情報科學的研究范疇及其應用價值。

[Purpose/significance] It is push forward that healthy develop of information science study with Chinese Characteristic and to be building theoretical system,for learn form foreign countries and draw on their success experience in innovation and development developing information science.[Method/process] thesis have been overall sum up the historical survey and research progress at main domain of developing information science’s theory and apply in 50 year,be utilize methods of historical retrospect and comparative analyze.[Result/conclusion] It is think that innovation breakthroughs of research achievement of information science has been gained in three respects into important question establish at subject,amended to basic assumption of theoretical system and it’s theory be closely combined to practice with compare scripture information science in west countries,to be expanded information science’s research category and application value in very great degree.
