摘要
学术社交网络的新型学术平台受到广泛关注,为了提升用户的信息质量体验,平台服务方对用户生成内容的社区形态实施了不同的管控措施。本研究基于服务质量评价理论,对全球72个国家的研究人员对学术社交网络感知信息质量的状况进行了调查,512份有效问卷通过偏最小二乘法实证检验了平台管控因素的作用大小和作用关系,同时考虑了成员社会资本的调节作用和信息质量体验的中介效应,以揭示用户对平台管控措施的感知判断过程。研究表明:①平台声誉、管控规则和技术诊断因素,均能不同程度地正向影响信息质量体验,而其中平台声誉还同时对信息质量期望产生一定的影响;②个体需要也会影响信息质量期望,但个体过往经历在本研究中未显示出对信息质量期望的直接作用;③社会资本对信息质量体验和感知信息质量之间的影响关系存在干扰性的调节效应;④信息质量体验在平台声誉、管控规则对用户感知信息质量的影响过程中具有不同程度的部分中介效应,但在技术诊断中则未见其中介效应。
The new platform of academic social networks has been receiving extensive attention.To enhance the user’s information quality experience,platform service providers have implemented different control measures for the user-generated contents.Based on the theory of service quality evaluation,this study investigates the status of perceived information quality of academic social networks in 72 countries around the world.A total of 512 valid questionnaires empirically test the relationships between platform factors through partial least squares analysis,considering both the moderating effect of members’ social capital and the mediating effect of information quality experience,to reveal the user perception and judgment process of the platform controls.Research shows that① platform reputation,management rules,and technical diagnostic factors can positively affect the information quality experience by varying degrees(βplatform reputation in formation quality=0.37;βmanagement rules-information quality=0.16;βtechnical diagnostic-information quality=0.23),and platform reputation also has a certain impact on the information quality expectations(βplatform reputation-information quality expectation=0.52).② Individual needs also affect the information quality expectations(βindividual needs-information quality expectation=0.12).However,the past experience of individuals does not show a direct effect on the information quality expectation in this study.③The influence of social capital on the relationship between information quality experience and perceived information quality has an interfering effect(βmoderating effect=-0.65);④ Information quality experience has different degrees of partial mediation effects in the process of platform reputation and management rules,affecting users’ perceived information quality;however,no intermediate effect is observed in the technical diagnosis.
