Introduction In the context of e-commerce, salespeople are

replaced by a customer interface. 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.

Literature review Customer interface quality

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.

Literature review(Cont.) Customer interface quality

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 This paper treats customer satisfaction as a

cumulative factor.

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 This paper defined customer loyalty as a

customer’s favorable attitude toward an e-commerce website that predisposes the customer to repeat buying behavior.

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.

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 navigationH2. Customer interface quality has a significant positive influence on customer satisfaction.

H3. Customer interface quality has a significant positive influence on switching costs. 2011/4/29

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.

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 decreases under conditions where high switching costs are perceived by customers.

H6. Customer satisfaction has a significant positive influence on customer loyalty.

H7. 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.

Data analysis and resultsAnalysis of the measurement model

We first developed the measurement model by conducting confirmatory factor analysis Conducting confirmatory factor analysis (CFA) 驗證性因素分析

The SEM was then estimated for hypotheses testing Structural equation model (SEM) 結構方程模式

The models were assessed by the maximum likelihood method using AMOS 5.0 Maximum likelihood method (MLE) 最大概似估計法

模式配適度分析

Data analysis and resultsAnalysis of the measurement model

平方均值估計殘差根 Root Mean Square Error of Approximation (RMSEA)又稱為 RMS 、 RMSE 、或自由度偏差。如果 RMSEA ≤0.05 ，代表「好」的模式適配；RMSEA≤0.08 ，都是「適合」的模式， RMSEA 是常用的絕對適配指標（ SEM外在品質）

基準適配指數 Nomed fit index (NFI)適配度指數 Goodness-of-fit index (GFI)比較適配指標 Comparative Fit Index

(CFI)理想數值需大於等於 0.9

調整的適配度指標 Adjusted goodness of fit index

(AGFI)

理想數值需大於等於 0.8

NC=(χ2/df) 來考驗模式適配度，若 NC 值介於 1.0~5.0 之間則代表 χ2值可接受， NC 值小於 1.0~2.0 時表測量模式有非常好的適配度，介於 2.0~3.0 之間表中度適配，大於 5.0 時表示模式尚未真實反應觀察資料，適配度不佳。

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 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

26

Discussions and implications Second, our study demonstrated that

customer interface quality both directly and indirectly influenced customer satisfaction 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

27

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 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

28

Discussions and implications Finally, our study found that switching costs

positively moderated the effects of customer satisfaction on customer loyalty 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

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 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

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 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
