【摘要】 【目的/意义】信息茧房等困境现象带来的负面效应越来越受到关注，本文构建的信息困境评价指标体系能够实现信息困境现象的量化研究，为高校学生突破信息困境提供精准参考依据。【方法/过程】从用户行为视角出发，采用因子分析法和CRITIC客观赋权法，构建了由信息极化、群体极化和认知极化3个一级指标、14个二级指标构成的信息困境评价指标体系，并以高校学生为例进行了实证分析。【结果/结论】评价指标体系具有较高的可靠性；信息困境现象由多维因素导致，群体交往影响相对显著；本科生比专科生和研究生更易于陷入信息困境；大一学生受信息技术和群体交往的影响较大，而大四学生受自我认知的影响较大。【创新/局限】基于用户行为视角构建信息困境评价指标体系，实现了信息茧房等困境现象的量化研究，从而支撑突破信息困境的相关研究。更多还原

【Abstract】 【Purpose/significance】The negative effects brought about by the information cocoon room and other dilemma phenomena have attracted more and more attention. The information dilemma evaluation index system constructed in this paper can realize the quantitative research on the information dilemma phenomenon, and provide accurate reference for college students to break through the information dilemma.【Method/process】From the perspective of user behavior, the factor analysis method and CRITIC objective weighting method are used to construct an information dilemma evaluation index system, and an empirical analysis is carried out by taking college students as an example. The evaluation index system consists of three first-level indicators, namely information polarization, group polarization and cognitive polarization, and 14 second-level indicators. [Results/conclusion]The evaluation index system has high reliability. The phenomenon of information dilemma is caused by multi-dimensional factors, and the influence of group communication is relatively significant. Undergraduates are more likely to fall into information dilemma than junior college students and graduate students, and freshmen are greatly affected by information technology and group communication, while seniors are greatly affected by self-cognition.【Innovation/limitation】Based on the perspective of user behavior, the evaluation index system of information dilemma is constructed, which realizes the quantitative research of information cocoon and other dilemmas, so as to support the relevant research of breaking through information dilemmas.更多还原
