Consumer attitudes and beliefs about security have significant effects on the intention to purchase online. Few studies have examined whether customer interface quality and perceived security affect customer satisfaction and switching costs, and in turn, influence customer loyalty. 4 2011/4/29 Literature review Customer interface quality 5 Parasuraman et al. developed a scale with four dimensions (i.e. efficiency of the website, system availability, privacy, and the post-transaction experience). Bauer et al. used five eTransQual dimensions (functionality/design, enjoyment, process, reliability and responsiveness). This study primarily focused on the components of customer interface quality that are related to online store atmospherics rather than to the entire online buying experience. 2011/4/29 Literature review(Cont.) Customer interface quality 6 This paper adopted four components of customer interface quality that deal with its atmosphere: Convenience Interactivity Customization Character 2011/4/29 Literature review(Cont.) Perceived security This paper defined perceived security as the extent to which a potential customer believes that the e-commerce website is secure for transmitting sensitive information. Customer satisfaction 7 This paper treats customer satisfaction as a cumulative factor. 2011/4/29 Literature review(Cont.) Switching costs Burnham et al. thought switching costs are not only economic in nature, but can also be psychological and emotional. This paper defined switching costs as the consumers perceptions of the time, money, and effort associated with changing e-service providers. Customer loyalty 8 This paper defined customer loyalty as a customer’s favorable attitude toward an e-commerce website that predisposes the customer to repeat buying behavior. 2011/4/29 Research model and hypotheses development Research model 9 2011/4/29 Research model and hypotheses development(Cont.) Hypotheses development Customer interface quality and perceived security Consumers may use interface quality as a surrogate indicator when forming beliefs about security. H1. Customer interface quality has a significant positive influence on perceived security. 10 2011/4/29 Research model and hypotheses development(Cont.) Hypotheses development Customer interface quality, satisfaction and switching costs Customer satisfaction toward a website depends primarily on the evaluation of its attributes. A good website avoids wasting customer time by providing orderly screens, simple search paths, fast and readable presentations, and simple navigation H2. Customer interface quality has a significant positive influence on customer satisfaction. H3. Customer interface quality has a significant positive influence on switching costs. 11 2011/4/29 Research model and hypotheses development(Cont.) Hypotheses development Perceived security, satisfaction and switching costs Consumers ' attitudes and beliefs about security have had significant effect on their intention to purchase online. High switching costs are engendered when a customer perceives one e-commerce website as being secure. H4. Perceived security has a significant positive influence on customer satisfaction. H5. Perceived security has a significant positive influence on switching costs. 12 2011/4/29 Research model and hypotheses development(Cont.) Hypotheses development Customer satisfaction, switching costs and loyalty Customers are satisfied, they believe that a website will deliver what they expect. The influence of customer satisfaction on customer loyalty H6.

Switching costs have a significant positive influence on customer loyalty. H8. The relationship between customer satisfaction and loyalty is weaker when customers perceive higher switching costs. 13 2011/4/29 Data analysis and results Data analysis and results Analysis of the measurement model Psychometric properties of measures Analysis of the SEM Testing the structural model Testing the moderating effect of switching costs Discussions and implications Conclusions 14 2011/4/29 Data analysis and results Data analysis and results Analysis of the measurement model Psychometric properties of measures Analysis of the SEM Testing the structural model Testing the moderating effect of switching costs Discussions and implications Conclusions 15 2011/4/29 Data analysis and results Analysis of the measurement model We first developed the measurement model by conducting confirmatory factor analysis The SEM was then estimated for hypotheses testing Conducting confirmatory factor analysis (CFA) 驗證性因素分析 Structural equation model (SEM) 結構方程模式 The models were assessed by the maximum likelihood method using AMOS 5.0 16 Maximum likelihood method (MLE) 最大概似估計法 2011/4/29 NC=(χ2/df)來考驗模式適配度,若 NC 基準適配指數 Nomed index (NFI) Data analysis and results 平方均值估計殘差根 Root fit Mean Square Error 調整的適配度指標 值介於1.0~5.0 之間則代表 χ2值可接受, 適配度指數 Goodness-of-fit index (GFI) of Approximation (RMSEA) Analysis比較適配指標 of the measurement Adjusted goodness of fit index model (AGFI) NC 值小於 1.0~2.0 Comparative 時表測量模式有非常 Fit Index (CFI) 又稱為RMS、RMSE、或自由度偏差。如果 好的適配度,介於 2.0~3.0 之間表中度 RMSEA ≤0.05,代表「好」的模式適配; 理想數值需大於等於0.8 適配,大於 理想數值需大於等於0.9 5.0 時表示模式尚未真實反 RMSEA≤0.08,都是「適合」的模式,RMSEA 模式配適度分析 應觀察資料,適配度不佳。 是常用的絕對適配指標(SEM外在品質) 17 2011/4/29 Data analysis and results Data analysis and results Analysis of the measurement model Psychometric properties of measures Analysis of the SEM Testing the structural model Testing the moderating effect of switching costs Discussions and implications Conclusions 18 2011/4/29 Data analysis and results Psychometric properties of measures 構念信度 Construct reliability (CR) 平均變異抽取量 Average variance extracted (AVE) 19 2011/4/29 Data analysis and results Data analysis and results Analysis of the measurement model Psychometric properties of measures Analysis of the SEM Testing the structural model Testing the moderating effect of switching costs Discussions and implications Conclusions 20 2011/4/29 Data analysis and results Analysis of the SEM - Testing the structural model 21 2011/4/29 Data analysis and results Data analysis and results Analysis of the measurement model Psychometric properties of measures Analysis of the SEM Testing the structural model Testing the moderating effect of switching costs Discussions and implications Conclusions 22 2011/4/29 Data analysis and results Analysis of the SEM - Testing the moderating effect of switching costs We used a multi-group causal analysis to test the moderating effect of switching costs 23 2011/4/29 Discussions and implications Data analysis and results Analysis of the measurement model Psychometric properties of measures Analysis of the SEM Testing the structural model Testing the moderating effect of switching costs Discussions and implications Conclusions 24 2011/4/29 Discussions and implications First, customer interface quality positively affected perceived security, which implied that a well-established website interface could improve customer perceptions of security 25 顧客介面品質會正向影響安全認知,這意味著一個介面設 計良好的網站可以改善顧客對安全的認知 2011/4/29 Discussions and implications Second, our study demonstrated that customer interface quality both directly and indirectly influenced customer satisfaction 26 研究證實顧客介面的品質會直接也會間接影響到顧客滿意 度 2011/4/29 Discussions and implications These results implied that higher perceived customer interface quality and security could encourage online shoppers to be more loyal, increasing the probability that they will return and repurchase from the e-commerce websites with which they were satisfied 27 證實高度介面品質與安全度會促使線上購物者更具有忠誠 度,同時也因為感到滿意而增加回購率 2011/4/29 Discussions and implications Finally, our study found that switching costs positively moderated the effects of customer satisfaction on customer loyalty 28 研究發現轉換成本對顧客滿意度與忠誠度這條關係具有正 向的調解效果 2011/4/29 Conclusions Data analysis and results Analysis of the measurement model Psychometric properties of measures Analysis of the SEM Testing the structural model Testing the moderating effect of switching costs Discussions and implications Conclusions 29 2011/4/29 Conclusions Customer interface quality can increase customer perceptions of security 顧客介面品質會增加安全認知 Customer interface quality and perceived security positively affected customer satisfaction and switching costs, and consequently customer loyalty 30 顧客介面品質與安全認知會正向影響顧客滿意度、轉換成 本與顧客忠誠度 2011/4/29 Conclusions Building customer loyalty in e-commerce is difficult; it requires online companies to differentiate themselves from their competitors. Practitioners should consider focusing more on customer interface design as a marketing strategy, particularly in improving customer convenience, interactivity, customization, and character 31 在電子商務中建立顧客的忠誠度是困難的。它需要使自己 能與其他競爭者有與眾不同的地方。從業人員應當考慮更 加注重顧客介面設計,來作為一種營銷策略,特別是在提 高顧客的便利性,互動性,客製化和特性這四個方面 2011/4/29 Consumer perception of interface quality, security, and loyalty in electronic commerce Q &A 32 2011/4/29
