【摘要】：互联网发展到今天,人们在网络上接触到的信息数量呈几何倍数增长。虽然信息的快速增长给人们带来了丰富的信息资源和更多的选择机会,但同时也带来了信息过载等问题。网络信息过载会给用户带来各种各样的负面的影响,特别是会影响用户在网络上获取信息时的效率。研究如何减轻甚至避免信息过载问题及其负面影响,使网络用户能够有效选择、利用信息,具有重要的理论意义和现实意义。本文基于用户信息获取行为的视角来研究信息过载的防控机制问题。本文认为,信息过载是用户信息获取的一种负效用,所以要研究网络信息过载防控机制的问题,就可以通过研究影响网络用户信息获取效用的因素及其作用机理,有针对性的对网络信息过载问题进行防控。本文在探讨网络信息过载出现原因及危害的基础上,通过总结网络用户信息获取过程各个阶段的影响因素,构建了网络用户信息获取行为模型,并利用结构方程建模的方法对理论模型进行验证性分析,最后提出了防控网络信息过载的机制。本文认为影响网络用户信息获取行为的因素可以从主体和客体两个角度来考虑。其中,主体因素包括5个指标,客体因素包括3个指标,经过多元回归分析以及Amos 20.0构建的结构方程模型路径图发现各个指标对信息获取过程三个阶段的影响有所不同。基于此,本文从信息主体和信息服务两个方面探讨了网络信息过载防控机制。
[Abstract]:With the development of the Internet, the amount of information that people come into contact with on the Internet is increasing exponentially. Although the rapid growth of information brings people rich information resources and more opportunities to choose, it also brings problems such as information overload. Network information overload will bring a variety of negative effects on users, especially on the efficiency of users to obtain information on the network. It is of great theoretical and practical significance to study how to reduce or even avoid the problem of information overload and its negative effects so that network users can choose and utilize information effectively. In this paper, the prevention and control mechanism of information overload is studied based on the behavior of user information acquisition. This paper holds that information overload is a negative utility of user information acquisition. Therefore, to study the prevention and control mechanism of network information overload, we can study the factors that affect the utility of network information acquisition and its mechanism. Prevention and control of network information overload. On the basis of discussing the cause and harm of network information overload, this paper summarizes the influence factors of each stage of network user information acquisition process, and constructs the behavior model of network user information acquisition. Finally, the mechanism of preventing and controlling the information overload of the network is put forward by using the method of structural equation modeling to verify the theoretical model. This paper holds that the factors that affect the behavior of information acquisition of network users can be considered from the aspects of subject and object. Among them, the main factor includes five indexes, the object factor includes three indexes. Through the multivariate regression analysis and the path diagram of the structural equation model constructed by Amos 20.0, it is found that the influence of each index on the three stages of the information acquisition process is different. Based on this, this paper discusses the prevention and control mechanism of network information overload from two aspects: information subject and information service.
