随着LBS在全球范围内的快速发展,LBS用户使用意向的影响因素及用户认知过程引发了相关领域学者的广泛重视。然而,以往研究缺乏对其中个人隐私问题的有效关注。本研究以公平理论和价值接受模型为理论基础,从个人隐私信息视角出发,探索LBS特性对用户使用意向的作用机制,构建LBS用户使用意向的认知过程模型,并利用264份有效问卷对研究模型进行实证检验。研究发现,首先,LBS平台的个性化和互动促进特征对用户的感知有用性和感知娱乐性都有正向提升作用;其次,互动促进会增加用户的隐私关注,而隐私政策会减少用户的隐私关注;最后,用户的感知有用性和感知娱乐性正向提升其感知价值,进而增加LBS使用意向,而用户的隐私关注会降低其感知价值,进而降低用户的使用意向。 相似文献

在技术接受模型(TAM)、情绪心理学、神经科学等理论的基础上,以一个电子商务推荐系统为例,通过情景实验的方式考察积极情绪对用户信息技术采纳行为的影响。对实验数据的统计分析表明积极情绪正向影响用户对信息技术的采纳意向,并存在直接和间接相结合的影响模式。即积极情绪既直接提高采纳意向,也同时通过感知风险、感知有用性和感知易用性作为不完全中介变量提高采纳意向。在考虑情绪因素后,技术接受理论得到了丰富,也为信息技术推广方获得更高的用户接受程度提供了新的切入点。 相似文献

Citizen users play important roles in the acceleration phase of energy transitions, during which small-scale renewable energy technologies (S-RET) become taken up more widely. From users’ perspective, turning the early, and typically slow, proliferation into a more rapid and widespread diffusion requires not only the adoption of S-RET but also the adaptation, adjustment, intermediation and advocacy of S-RETs. These activities become necessary because S-RET face a variety of market, institutional, cultural and environmental conditions in different countries. New Internet-based energy communities have emerged and acted as key user-side transition intermediaries that catalyse these activities by qualifying market information, articulating demand and helping citizen users to reconfigure the standard technology to meet the specificities of different local contexts. In doing so, Internet communities foster an appreciatively critical discourse on technology. Such user intermediation is important in expanding the markets for S-RET beyond that of enthusiasts, environmentalists and other early adopters, to the early majority of adopters who demand more exposure, clearer information and less uncertainty about new technology options. 相似文献

基于复杂社会网络的创新扩散多智能体仿真研究 《科学学研究》2013,(2):310-320
创新扩散是由潜在采纳者的微观采纳决策所共同涌现出的宏观动力学行为。以复杂社会网络为创新扩散建模载体,通过建立潜在采纳者在社会学习和规范压力双重影响下的创新采纳决策及扩散机制,运用基于多智能体的仿真研究方法,研究微观层面因素是如何影响创新的宏观扩散。研究发现：无标度社会网络下的创新扩散深度最大及扩散速度最快;潜在采纳者的创新信息评价策略会显著地影响创新扩散深度;初始采纳者比例的提高可加快创新扩散速度,但无法持续提高扩散深度;过强或过弱的观念领导者创新性,均不利于创新扩散的深度;不同的初始采纳者类型对创新扩散深度、以及观念领导者创新性的强弱对创新扩散速度的影响取决于社会网络的拓扑结构。研究结果对于制定创新推广策略具有一定的指导意义。 相似文献

核电“走出去”是我国 “一带一路”战略的重要着力点,存在抢占市场与投资高风险的决策困境。核电企业“走出去”需要抓住关键的机会,错误时机的投资失败率很高。三代核电技术的出现加剧了市场的不确定性,新技术的扩散特征显著地影响到“走出去”机会窗口的开启。借鉴Bass模型,发现技术创新系数越大,核电“走出去”机会窗口宽度越小、模仿系数越大,机会窗口宽度越大;通过对“华龙一号”扩散预测证实了投资最佳时机相对于收益最佳时刻的后置。目前,由于福岛核事故对安全技术产生的重大影响,我国核电“走出去”的机会还不是很成熟,应该加强合作网络的建设,等待最佳时机。 相似文献

Information and communication technology (ICT) developments and trends in recent years have had great impact on the banking sector worldwide. In many developed and developing countries, the use of disruptive innovation technologies has accelerated change in the way banking business is conducted, consumers being swept along with such change. However, in many countries, such as Oman, there are deep routed cultural and religious factors that cause consumers to question the acceptance of such changes. Through the use of a theoretical framework built on technology acceptance frameworks and models, and empirical evidence from key market segments of the Omani banking market, the research explores the factors that influence Omani consumer acceptance of on-line banking. The findings are significant in that trust, usability and perceived quality are deemed key drivers. This is probably not unexpected, however, what is interesting is that the market profile is skewed to middle aged users, with social standing and “herd” mentality does not affect the adoption of the technology. This, combined with the emerging mobile savvy younger generation poses an interesting challenge for the future of the banking sector in Oman and implies a need for the sector to rethink the strategic use of, and approach to, implementation of on-line banking in a way that is complementary to the cultural and ethological dimension of the market. In effect, the banking sector will need to manage the covert tension between technology driving “fast time”, and the Omani culture, religion and tradition demanding face to face “slow time”. 相似文献

A key element in the adoption of innovation is addressing the knowledge gap caused by its introduction in practice. This study examines the context in which information is searched, found and retrieved, reviewing previous related research work, especially in the area of cognitive information retrieval. As result of an extensive review of research literature on the adoption of online learning design systems in education and on information behaviour, the study proposes a social adoption of innovation model, which includes information systems and social networks, and features innovators and adopters of innovation that influence each other and participate simultaneously in the process of knowledge generation. The study also proposes two symbolic equations for general knowledge behaviour and general information seeking skills that reflect the contribution of multiple sources of information and the type of skills that are needed as part of the overall knowledge behaviour. 相似文献

Platform sponsors strive to govern their platform ecosystem to be generative in supplying complementary products abreast of adoption targets. A more comprehensive pool of adopters requires high value creation capacity. Leveraging the opening of borders to complementors for competing in adoption could be a winning strategy when fostering generativity. Seldom has this view been studied empirically; therefore, the present study examines the effects of supply-side openness on platform adoption and investigates generativity's role between them as a mediator. Moreover, the study explores the heterogeneity between early and late adopters in generativity's influence. We also analyze generativity in mediating the effect of openness by the moderating influence of technological complexity. Consequently, a moderated mediation analysis is employed on panel data of 8960 video games in six platforms and three regions. Results show that platforms' openness propels their adoption, and generativity mediates this effect. Specifically, this study clarifies the idea that supply-side openness, the proliferation of more open innovation strategies, enhances platforms' value generation capacity, and both enhance platform adoption. Findings also indicate that platforms' technological complexity positively moderates the mediation role of generativity, revealing that in more complex platforms, openness increases generativity more intensely. 相似文献
