为健全完善科技成果评价体系，更好发挥科技成果评价作用，促进科技与经济社会发展更加紧密结合，加快推动科技成果转化为现实生产力，近日，国务院办公厅发布了《关于完善科技成果评价机制的指导意见》（以下简称《意见》）。

《意见》中明确指出：要全面准确评价科技成果的科学、技术、经济、社会、文化价值。根据科技成果不同特点和评价目的，有针对性地评价科技成果的多元价值。技术价值重点评价重大技术发明，突出在解决产业关键共性技术问题、企业重大技术创新难题，特别是关键核心技术问题方面的成效。要健全完善科技成果分类评价体系。应用研究成果以行业用户和社会评价为主，注重高质量知识产权产出，把新技术、新材料、新工艺、新产品、新设备样机性能等作为主要评价指标。不涉及军工、国防等敏感领域的技术开发和产业化成果，以用户评价、市场检验和第三方评价为主，把技术交易合同金额、市场估值、市场占有率、重大工程或重点企业应用情况等作为主要评价指标。要改革完善科技成果奖励体系。强化国家科技奖励与国家重大战略需求的紧密结合，加大对基础研究和应用基础研究成果的奖励力度。要坚决破解科技成果评价中的“唯论文、唯职称、唯学历、唯奖项”问题。全面纠正科技成果评价中单纯重数量指标、轻质量贡献等不良倾向，鼓励广大科技工作者把论文写在祖国大地上。以破除“唯论文”和“SCI至上”为突破口，不把论文数量、代表作数量、影响因子作为唯一的量化考核评价指标。对具有重大学术影响、取得显著应用效果、为经济社会发展和国家安全作出突出贡献等高质量成果，提高其考核评价权重。不得把成果完成人的职称、学历、头衔、获奖情况、行政职务、承担科研项目数量等作为科技成果评价、科研项目绩效评价和人才计划评审的参考依据。
