突发事件网络新闻与网民信息需求表达的协整分析——基于问题胶囊事件的实证研究

Study of the Relationship between Web News and Netizens ’ Information Need by the Method of Cointegration Analysis——Base on Inferior Capsule Event

本文基于协整理论,通过EG检验、Granger因果分析,对突发事件网络新闻与网民信息需求表达的数量关系进行了数学建模,并进行实证分析,结果表明:网络新闻报道的数量会对网民信息需求表达数量存在单向引导关系,网络新闻的报道量与用户信息需求表达量存在均衡关系。

This paper, which is based on co-integration theory, uses the EngeI-Granger test and Granger causality analysis to build a model which is used to verify the causal and effect relationship between web news and netizens＇ information need in emergency situation. The result shows that there is a unidirectional causality from web news to netizens＇ information need, and there is also an equilibrium relationship between web news and netizens＇ information need.
