【目的/意义】为探究产品伤害危机情境下搜索引擎用户的持续使用行为的影响因素及其内在作用机理。【方法/过程】在整合信息系统持续使用的期望确认理论、感知风险理论、归因理论、计划行为理论和习惯理论的基础上,提出研究假设并构建了理论模型,同时进行了实证研究。【结果/结论】研究结果显示,期望确认正向刺激搜索引擎用户的感知有用性和使用满意度,感知有用性能促进使用满意度,使用满意度能促进持续使用意愿;责任归因对感知使用风险具有促进作用,感知使用风险对使用满意度和持续使用意愿均具有抑制作用;持续使用态度正向影响持续使用意愿,持续使用意愿和使用习惯均正向影响持续使用行为。

英文摘要：

【Purpose/significance】To explore factors influencing users＇ continuance usage behaviour of search engine inthe context of product-harm crisis and their internal interaction mechanism.【Method/process】This paper integrates theexpectation confirmation model of IS continuance, the perceived risk theory, the attribution theory, the theory of plannedbehaviour and the habit theory. Hypotheses and theoretical model are proposed. The article has carried on the empiricalresearch to the theory model.【Result/conclusion】The results shows that, expectation confirmation has significant positiveimpact on users＇ perceived usefulness and using satisfaction to search engine, perceived usefulness promotes satisfactionand satisfaction promotes continuance usage intention. Attribution of responsibility has significant positive impact onperceived using risk, while perceived using risk has a negative impact on continuance usage intention and usingsatisfaction. Continuance usage attitude has a positive effect on continuance usage intention, while continuance usageintention and using habit have significant positive impact on continuance usage behaviour.
