系统、科学的评估指标体系是确定技术成果价值的基础，在理论研究的基础上，本文构建技术成果价值影响因素特征分类指标体系，使用HedonicPrice模型对技术成果价值影响因素进行实证研究。研究发现：经济效益是技术成果价值的决定性因素，技术水平对技术成果价值变动解释能力弱于经济效益，技术特点对技术成果价值变动的解释能力较弱；技术成果的技术水平与技术特点在一定程度上加强了技术成果的经济效益与其价值之间的关系，技术水平与技术特点对技术成果经济效益与其价值存在双重影响，在技术成果价值影响因素中属于准调节变量。最后，提出完善技术成果价值评估指标体系的对策建议。 

 Systematic and scientific evaluation index system is the basis for accurate assessment of technological achievement values, and on the basis of theoretical research, this paper constructs the index system and carries out an empirical study of the influencing factors of technological achievement values based on the Hedonic Price Model. The study result shows that the technical level and economic benefits of technological achievements are positively correlated with their prices, and legal status has a weak explanatory capability to the value of technological achievements. Furthermore，the technical level and legal status somewhat strengthens the relationship between economic benefits and technological achievement values. Due to this dual impact of technical level and legal status on economic benefits and technological achievement values, the technical level and legal status are quasi-moderating variables in statistical terms. Finally, the paper puts forward some countermeasures and suggestions to perfect the value evaluation index system of technological achievements.
