即时通讯市场的竞争日益激烈,对用户选择及继续使用行为的研究是制定有效的竞争策略、占有更多市场份额的必要前提。本文综合了技术接受模型(TAM)和期望确认模型(ECM),从期望差距、感知有用性、感知易用性、感知娱乐性、感知风险、感知费用、感知激励和网络外部性8个方面构建了用户选择和继续使用某种即时通讯产品的行为意向研究模型。通过问卷调查收集数据,利用统计软件SPSS对模型量表进行信度和效度分析,并采用结构方程模型的分析软件Lisrel对研究模型的假设进行了检验,最后对研究结果进行讨论,并提出了对策建议。
Confronting increasingly intensive competition of Instant Messaging market, we should study on the user's choice and usage intention in order to make effective competition strategies and increase market share. According to Technology Acceptance Model(TAM)and Expectation Confirmation Theory(ECT), the model why users have intention to continue use instant message service was built from eight aspects, expectation confirmation, perceived usefulness, perceived ease of use, perceived playfulness, perceived risk, fell expense, perceived inspirit and network externalities. The scaling of reliability and validity of the model was tested through SPSS 13.0 and the hypotheses of the structure equation model were verified by Lisrel 8.7. On the basis of the research results, corresponding countermeasures are also DrODosed.
