以科学数据为研究对象,在分析科学数据价值鉴定必要性的基础上,提出了科学数据价值鉴定的五大基本原则,包括全面性、历史性、效益性以及差异性与即逝性原则。并以这五大基本原则为指导,从科学历史与经济价值、科学数据质量、内容标准、成本效益标准以及相对价值与法律道德限制性标准六个方面提出了科学数据价值鉴定依据。 Based on the analysis of the necessity of scientific value identification of the scientific data, this paper proposes five basic principles of the scientific value identification of the scientific data, including comprehensiveness, historicity, profitability and the principle of difference and the fleetingness. Guided by these five basic principles, we put forward the scientific data value identification basis from six aspects of scientific history and economic value, scientific data quality, content standard, cost-benefit standard, relative value and legal moral restriction standard.
