科研信息服务融合使用行为影响因素实证研究

An Empirical Study of the Adoption Behavior of Scientific Information Service Mashup

科研信息服务融合通过实现多元科研信息资源及服务的有机融合,形成新的基于Web内容复合的应用,为科研活动提供一站式可视化解决方案。本文利用结构方程模型方法,研究科研信息服务融合使用行为意图的影响因素及各影响因素之间的关系。研究发现,科研信息服务融合使用行为意图受用户感知有用性和感知易用性直接影响,对科研信息服务融合的集成性感知是影响用户感知有用性和感知易用性的关键,而网络外部性和个性化程度则通过影响感知易用性间接影响用户使用行为意图。

Scientific information mashup provides a visualization solution for scientific research activities by integratingseveral scientific information resources and services into one compound application based on web. This paper adopts struc-tural equation modeling to find the influencing factors affecting user＇s adoption behavior intention of scientific informationmashup. The results confirm that both perceived usefulness and perceived ease of use have direct impacts on the adoptionbehavior of scientific information mashup. The results also indicate that perceived integration is the key for perceived use-fulness and perceived ease of use, while network externality and individualization have significantly impacts on the per-ceived ease of use, and further influence adoption behavior intention indirectly.
