博士后制度已有一百多年的歷史。世界上普遍認為,博士后研究經歷不僅是博士們在取得博士學位后找到理想工作前的過渡階段,而且也被看成是未來科學家職業生涯中必要的準備階段。中國的博士后制度雖然起步晚,但已形成獨具特色和相對獨立、完善的人才培養和使用機制,成為造就高水平人才的重要途徑,它已經并將繼續為推進中國的科技教育事業和經濟發展發揮越來越重要的作用。
中國博士后制度實施之初,國家就設立了博士后科學基金,專門資助博士后研究人員開展創新探索。與其他基金主要資助“項目”不同,博士后科學基金的資助目標是“人”,也就是通過評價博士后研究人員的創新能力給予基金資助。博士后科學基金針對博士后研究人員處于科研創新“黃金時期”的成長特點,通過競爭申請、獨立使用基金,使博士后研究人員樹立科研自信心,塑造獨立科研人格。經過30年的發展,截至2015年底,博士后科學基金資助總額約26.5億元人民幣,資助博士后研究人員5萬3千余人,約占博士后招收人數的1/3。截至2014年底,在我國具有博士后經歷的院士中,博士后科學基金資助獲得者占72.5%。博士后科學基金已成為激發博士后研究人員成才的一顆“金種子”。
在博士后科學基金的資助下,博士后研究人員取得了眾多前沿的科研成果。將這些科研成果出版成書,既是對博士后研究人員創新能力的肯定,也可以激發在站博士后研究人員開展創新研究的熱情,同時也可以使博士后科研成果在更廣范圍內傳播,更好地為社會所利用,進一步提高博士后科學基金的資助效益
