文章在回顾信息源及其两大影响因素——信息源质量与信息源可得性的相关研究即成本收益比率理论、齐夫最小努力原则、自我决定论等的基础上,通过构建概念模型,并依据对中国科学院50名硕士研究生的调研情况进行统计分析,验证二者对于信息源使用意向的影响,通过引入自我动机为调节变量,验证出在自我动机的调节下,信息源质量对于信息源使用意向正向影响的增强。 Based on the review of the information source and its two major influencing factors - the related research of the information source quality and the availability of the information source, namely, the cost-benefit ratio theory, the principle of least-effort of Zifu, self-determination theory and so on, through constructing the conceptual model, And based on the survey of 50 master’s graduates from Chinese Academy of Sciences, we conducted statistical analysis to verify the impact of the two on the intention of using information sources. By introducing self-motivation as a regulatory variable, it is verified that under the regulation of self-motivation, The positive effect of intention to use enhancement.
