【摘要】：互聯(lián)網(wǎng)發(fā)展到今天,人們?cè)诰W(wǎng)絡(luò)上接觸到的信息數(shù)量呈幾何倍數(shù)增長(zhǎng)。雖然信息的快速增長(zhǎng)給人們帶來了豐富的信息資源和更多的選擇機(jī)會(huì),但同時(shí)也帶來了信息過載等問題。網(wǎng)絡(luò)信息過載會(huì)給用戶帶來各種各樣的負(fù)面的影響,特別是會(huì)影響用戶在網(wǎng)絡(luò)上獲取信息時(shí)的效率。研究如何減輕甚至避免信息過載問題及其負(fù)面影響,使網(wǎng)絡(luò)用戶能夠有效選擇、利用信息,具有重要的理論意義和現(xiàn)實(shí)意義。本文基于用戶信息獲取行為的視角來研究信息過載的防控機(jī)制問題。本文認(rèn)為,信息過載是用戶信息獲取的一種負(fù)效用,所以要研究網(wǎng)絡(luò)信息過載防控機(jī)制的問題,就可以通過研究影響網(wǎng)絡(luò)用戶信息獲取效用的因素及其作用機(jī)理,有針對(duì)性的對(duì)網(wǎng)絡(luò)信息過載問題進(jìn)行防控。本文在探討網(wǎng)絡(luò)信息過載出現(xiàn)原因及危害的基礎(chǔ)上,通過總結(jié)網(wǎng)絡(luò)用戶信息獲取過程各個(gè)階段的影響因素,構(gòu)建了網(wǎng)絡(luò)用戶信息獲取行為模型,并利用結(jié)構(gòu)方程建模的方法對(duì)理論模型進(jìn)行驗(yàn)證性分析,最后提出了防控網(wǎng)絡(luò)信息過載的機(jī)制。本文認(rèn)為影響網(wǎng)絡(luò)用戶信息獲取行為的因素可以從主體和客體兩個(gè)角度來考慮。其中,主體因素包括5個(gè)指標(biāo),客體因素包括3個(gè)指標(biāo),經(jīng)過多元回歸分析以及Amos 20.0構(gòu)建的結(jié)構(gòu)方程模型路徑圖發(fā)現(xiàn)各個(gè)指標(biāo)對(duì)信息獲取過程三個(gè)階段的影響有所不同�；诖�,本文從信息主體和信息服務(wù)兩個(gè)方面探討了網(wǎng)絡(luò)信息過載防控機(jī)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.
