博士后制度已有一百多年的历史。世界上普遍认为,博士后研究经历不仅是博士们在取得博士学位后找到理想工作前的过渡阶段,而且也被看成是未来科学家职业生涯中必要的准备阶段。中国的博士后制度虽然起步晚,但已形成独具特色和相对独立、完善的人才培养和使用机制,成为造就高水平人才的重要途径,它已经并将继续为推进中国的科技教育事业和经济发展发挥越来越重要的作用。
中国博士后制度实施之初,国家就设立了博士后科学基金,专门资助博士后研究人员开展创新探索。与其他基金主要资助“项目”不同,博士后科学基金的资助目标是“人”,也就是通过评价博士后研究人员的创新能力给予基金资助。博士后科学基金针对博士后研究人员处于科研创新“黄金时期”的成长特点,通过竞争申请、独立使用基金,使博士后研究人员树立科研自信心,塑造独立科研人格。经过30年的发展,截至2015年底,博士后科学基金资助总额约26.5亿元人民币,资助博士后研究人员5万3千余人,约占博士后招收人数的1/3。截至2014年底,在我国具有博士后经历的院士中,博士后科学基金资助获得者占72.5%。博士后科学基金已成为激发博士后研究人员成才的一颗“金种子”。
在博士后科学基金的资助下,博士后研究人员取得了众多前沿的科研成果。将这些科研成果出版成书,既是对博士后研究人员创新能力的肯定,也可以激发在站博士后研究人员开展创新研究的热情,同时也可以使博士后科研成果在更广范围内传播,更好地为社会所利用,进一步提高博士后科学基金的资助效益
