摘 要 知识被认为是获取经济效益的必要元素，信息化社会更是如此，信息传播中的“数字鸿沟”，会加剧经济上的贫富分化。本文采用当代大学生对付费阅读调研数据，借助调节效应模型，采用多元阶层回归分析方法验证动机对数字鸿沟的影响。具体来看，采用认知卷入度，情感卷入度，行为卷入度三个动机指标，在动机条件模型框架下研究动机与社会经济地位在知沟形成过程中的交互作用。研究结果表明，对于社会经济地位比较低的群体而言，当情感卷入度，行为卷入度和认知卷入度较高时，可以从媒介使用中获取更多的知识，从而缩小由于社会经济地位差异导致的知沟。部分动机指标可以缩小因为社会经济地位造成的知识获取的差异，这就从个体动机和社会经济地位角度，提供了对数字鸿沟现象产生机制的一种跨层次解释。该研究丰富和扩展了数字鸿沟的理论框架，扩宽了其视野，并对知识的传播具有积极的意义，对国家的良性发展也有重要的指导意义。关键词：个体动机； 数字鸿沟； 调节机制； 社会经济地位AbstractKnowledge is considered as a necessary element to obtain economic benefits, especially in the information society. The "digital divide" in information dissemination will aggravate the economic polarization between the rich and the poor. This is a dangerous signal for any country or region. At present, the trend of "digital divide" is expanding in many aspects. In this paper, we use the survey data of contemporary college student, with the help of moderating effect model, and use multilevel regression analysis to verify the impact of motivation on the digital divide. Specifically, the interaction between motivation and socioeconomic status in the formation of knowledge gap is studied under the framework of motivation condition model by using three motivation indicators: cognitive involvement, emotional involvement and behavioral involvement. The results show that for groups with low social and economic status, when emotional involvement and behavioral involvement are high, more knowledge can be acqu...
