[目的/意义]构建在线科学交流中的学术论文影响力评价指标和模型，丰富学术论文影响力评价的内容和方法。[方法/过程]首先，分析目前学术评价研究中指标的特点，参考Altmetrics指标体系，选取国内几大权威在线媒体平台为研究平台，获取相关指标数据。其次，通过与被引频次和下载量的相关性筛选指标，运用主成分分析法构建评价模型。最后，以实证分析验证模型的有效性。[结果/结论]通过对学术论文在网络环境下的影响力研究及评价，改进传统学术论文评价模型的单一性和片面性，优化学术论文影响力评价的指标体系，为相关研究提供新思路和方法。
[Purpose/significance] This paper is intended to construct the evaluation index and model of academic papers impact in online scientific exchange, and enrich the content and method of academic papers impact evaluation.[Method/process] First of all, this paper analyzed the characteristics of the indicators in the current academic evaluation research. Then, it selected several authoritative online media platforms as the research platform according to the altmetrics indicator system, and then, it obtained relevant index data from these platforms. Secondly, the indexes were screened through the correlation between the quoted frequency and the download volume, and the evaluation model was constructed by principal component analysis. Finally, it conducted the empirical analysis to verify the validity of the model.[Result/conclusion] Through the research and evaluation on the impact of academic papers under the network environment, this paper improves the unity and one-sidedness of traditional academic papers evaluation models,and optimizes the evaluation index system of academic papers.Thus, provides new ideas and methods for related research.
