摘要

The recent few years have witnessed remarkable growth in the use of computer-based VoIP phone service, which allows computer users to talk to other people at no or little cost via calls through an Internet connection. Employing a theoretical framework from the technology acceptance model (TAM), the uses and gratifications approach, diffusion theory, and the theory of media richness, this study aims to examine the process of adoption and use of computer-based VoIP phone service, and further derive the determinants of technology acceptance by looking at user characteristics.;A nationwide online survey was conducted in the U.S., yielding a total sample size of 1,656 of which the valid number of computer-based VoIP phone service users was 309. Results from structural equation modeling analyses showed that users' perceived ease of use had a significant impact on perceived usefulness, which in turn affected their attitude toward using computer-based VoIP phone service, as the TAM suggested. However, users' perceived usefulness of the technology did not exhibit a direct influence on actual use of the technology, contrary to expectation.;Among the exogenous variables utilized in the current study, the motivations for communication and instrumental use played the most important role in the explanation of adoption and use of computer-based VoIP phone service. The motivation for entertainment, however, had negative effects on perceived ease of use, perceived usefulness, and attitude toward using the technology. In the case of system characteristics, perceived cost effectiveness affected all dependent variables either directly or indirectly, confirming that cost reduction would be the greatest attraction of computer-based VoIP phone service. In addition, users of the technology exhibited higher Internet self-efficacy, owned more communication technology products, and showed greater innovative attitude than non-users.;Findings of the study offer both theoretical and practical implications. The study proposes an integration of the TAM and the uses and gratifications approach by incorporating motivations as critical constructs that facilitate perceived ease of use and perceived usefulness. Moreover, the study suggests that the vendors of computer-based VoIP phone service need to develop unique features and functions beyond the cost advantage of the technology.
機(jī)譯：最近幾年見(jiàn)證了基于計(jì)算機(jī)的VoIP電話服務(wù)的使用顯著增長(zhǎng)，該服務(wù)使計(jì)算機(jī)用戶可以通過(guò)Internet連接通過(guò)電話免費(fèi)或與其他人通話。本研究采用技術(shù)接受模型（TAM），使用和滿足方法，擴(kuò)散理論以及媒體豐富性理論的理論框架，旨在研究基于計(jì)算機(jī)的VoIP電話服務(wù)的采用和使用過(guò)程，并進(jìn)一步研究通過(guò)查看用戶特征來(lái)得出技術(shù)接受度的決定因素。;在美國(guó)進(jìn)行了一項(xiàng)全國(guó)性在線調(diào)查，得出總樣本量為1,656，其中基于計(jì)算機(jī)的VoIP電話服務(wù)用戶的有效數(shù)量為309。結(jié)構(gòu)方程式的結(jié)果建模分析表明，用戶的易用性對(duì)感知的實(shí)用性有重大影響，這反過(guò)來(lái)影響了他們對(duì)使用基于計(jì)算機(jī)的VoIP電話服務(wù)的態(tài)度，正如TAM所建議的那樣。但是，用戶對(duì)技術(shù)的感知實(shí)用性并未對(duì)技術(shù)的實(shí)際使用產(chǎn)生直接影響，與預(yù)期相反。在當(dāng)前研究中使用的外生變量中，交流和工具使用的動(dòng)機(jī)在技術(shù)中起著最重要的作用。對(duì)基于計(jì)算機(jī)的VoIP電話服務(wù)的采用和使用的說(shuō)明。然而，娛樂(lè)的動(dòng)機(jī)對(duì)感知的易用性，感知的有用性以及使用該技術(shù)的態(tài)度產(chǎn)生了負(fù)面影響。在系統(tǒng)特性的情況下，感知到的成本效益直接或間接地影響了所有因變量，這證實(shí)了降低成本將是基于計(jì)算機(jī)的VoIP電話服務(wù)的最大吸引力。此外，與非用戶相比，該技術(shù)的用戶具有更高的互聯(lián)網(wǎng)自我效能，擁有更多的通信技術(shù)產(chǎn)品并表現(xiàn)出更大的創(chuàng)新態(tài)度。研究結(jié)果提供了理論和實(shí)踐意義。該研究通過(guò)將動(dòng)機(jī)作為促進(jìn)可感知的易用性和可感知有用性的關(guān)鍵結(jié)構(gòu)納入動(dòng)機(jī)，提出了TAM與使用和滿足方法的整合。此外，研究表明，基于計(jì)算機(jī)的VoIP電話服務(wù)的供應(yīng)商需要開發(fā)獨(dú)特的功能，超越該技術(shù)的成本優(yōu)勢(shì)。
