基于政府门户网站视角的中美预算公开信息比较与评价

互联网是政府信息公开的一种主要途径。基于政府门户网站这一公开渠道及网络信息传播特点,可以从专门性、全面性、详细性、动态性、便利性等不同角度,对美国和中国的201 1年度中央(联邦)预算公开信息进行比较。虽然近几年中国在预算公开方面取得了一定进展,但仍处在起步阶段,预算公开信息呈现典型的"碎片化"特征,缺乏制度性保障,与社会期望仍有较大的差距。因此,应以政府门户网站为主要公开渠道,提高中国政府预算公开信息的质量。

文章在文献综述的基础上,提出了零售购物网站可用性与顾客忠诚的关系模型,并通过实证研究对模型进行了验证。研究表明,零售购物网站可用性是一个多维概念,由内容因素、交流因素、技术因素、情感因素和定住因素构成。此外研究还表明,零售购物网站的可用性对情感偏爱和重复购买存在显著的正向影响。     

Lowest price guarantees on airline websites: Perceived believability,perceived value,and purchase intentions

Although lowest price guarantees (LPGs) are common on airlines’ official websites, a deeper understanding of how customers evaluate these guarantees is lacking. This study examines the effects of two LPG terms—depth of refund and refund conditions—on customer perceptions and purchase intention. An experiment with a 2 × 2 factorial design was conducted with a sample of 282 adults, and structural equation modelling was used to test the model. The results show that refund depth increases customer purchase intention by enhancing perceptions of the believability and value of the LPG. Strict refund conditions enhance customer purchase intention by increasing the believability of the LPGs.     

Mobile Commerce Website Success: Antecedents of Consumer Satisfaction and Purchase Intention

With the rapid development of apparel mobile commerce in the United States, more companies view mobile commerce as a new source of competitive advantage. Despite the importance of apparel mobile website quality and its effect on consumer satisfaction and future purchase stimulus, extant research has paid little attention to these topics. This study proposes a website quality–consumer satisfaction–purchase intention research model based on the self-regulatory process theory. Six dimensions of apparel mobile website quality—website visual appeal, apparel visual appeal, brand trust, website information quality, website response time, and website security—were investigated. In all, 293 eligible responses were collected via an online survey. Multiple regression analysis was utilized to test the proposed relationships. Results reveal that website information quality, website visual appeal, apparel visual appeal, and website security positively affect consumer satisfaction toward apparel mobile commerce websites, while website response time and brand trust show insignificant impacts on consumer satisfaction. With higher satisfaction on an apparel mobile commerce website, consumers are more likely to purchase apparel through the website.     

Why do you use Yelp? Analysis of factors influencing customers’ website adoption and dining behavior

The number of review websites has increased within the past years since more people rely on online reviews to help their decision-making process. Previous studies have either focused on the attributes of the content posted on review websites (i.e., reviews) or customers’ behavior concerning their selection of review website on which to post reviews. This study, however, extends the Technology Acceptance Model (TAM) to investigate the factors that influence individuals’ restaurant review website adoption behaviors to read reviews and make dining decisions. In addition, this study will look at the differences in individuals’ perceptions of various restaurant review websites (i.e., Yelp vs. others). The findings revealed the role of influential factors on individuals’ review website adoption and dining decisions as well as the differences in proposed structural relationships among various restaurant review websites.     

Analysing behavioural differences between e- and m-bookers in hotel booking

This study analysed the behavioural differences between e- and m-bookers in online hotel booking. The theoretical relationships among functionality and usability, perceived value for money and time, and satisfaction and loyalty were analysed based on the quality–satisfaction–loyalty framework. Results from a sample of 431 and 401 e- and m-bookers, respectively, affirmed the similarities and differences between the two types of bookers. Results also showed that e- and m-bookers substantially differ in their perceptions on functionality and usability performance, perceived value for money and relative importance of functionality and usability in online hotel booking. Moreover, the findings revealed the moderating effects of perceived value for money and time on the satisfaction–loyalty link among m-bookers.     

Fashionability vis-à-vis rationality: investigating factors driving users’ e-tourism website stickiness

Understanding what drive users’ website stickiness is of strategic importance for e-tourism managers. This study examines the role of a neglected construct ‘perceived fashionability’ in forming users’ e-tourism website stickiness in comparison with four commonly studied rational factors: system quality, information quality, security and e-shopping value. Drawing upon dual-system theories and social influence theories, a conceptual model with hypotheses was developed and tested. A sample of 376 e-tourism website users in China participated in this study. The results indicate that perceived fashionability has a positive impact on user's stickiness to the website, and perceived fashionability also performs a mediating role between website security and stickiness. This study contributes to theory by explaining that website stickiness is not entirely driven by rationality but also perceived fashionability. Managerial implications for e-tourism strategies are provided.     

基于社会责任视角的我国非营利组织网站测评研究

在互联网环境下，非营利组织纷纷建设门户网站加强与社会大众以及各利益相关方的沟通联系。随着非营利组织社会责任考量的日益重要，但目前对非营利组织通过网站履行社会责任的可行性评估一直处于空白状态，基于该视角，对中国17家最具有代表性的中国非营利组织进行了为期24天的网站检测，通过层次分析法对网站数据计算分析并进行网站排名。测评结果显示，目前中国优秀非营利组织在职能责任方面，依然存在网站更新频率低，活动相关性不足等问题，网站建设和运营方面仍有很大完善空间。
