According to Chaudhury & Kuiboer ¹, e-commerce has been making significant contributions to reduction in costs of doing business, improved products/services quality, new customer and supplier penetration, and generation of new ways or channels for product distributions. Such benefits can be realized in not only large enterprises but also small and medium enterprises (Huff et al., 2000).

Kotler ² claimed that understanding consumers has become the focus of attention in the business due to the fact that the prosperity of companies is heavily dependent on satisfying customers and keeping them loyal. In online marketing, the consumer will grants permission and controls the interaction. Butler and Peppard (1998) stated that the heart of marketing management is to understand consumer psychology, irrespective of whether one is dealing with the cyber world or the physical world. Rossiter and Percy (1998) showed that for tourism and hospitality marketers to successfully communicate with their customers and, ultimately, to implement effective online marketing activities, they need to study the behavior of consumers. They concluded that marketing of goods and services in the cyber market may be different from dealing with traditional markets. It demands a good understanding of consumer behavior, as well insight into how pioneering technologies challenge the conventional concepts behind existing theories and models.

According to Zwass ³, E-commerce is sharing business information, maintaining business relationships, and conducting business transactions by means of telecommunications networks. Laundon, K.C, (2014) stated that exchange of value is key for understanding the scope of e- commerce as without any exchange in value no commerce occurs.

2. Research Methodology

The research approach of this study was author chooses is quantitative method.

According to Creswell (2003), quantitative approach is one type of research, in which the investigator primarily uses post positivist claims for developing knowledge (i.e. cause and effect thinking, reduction to specific variables and hypotheses and questions, use of instrument and observation, and the test of theories), employs strategies of inquiry such as experiments and surveys and collects data on predetermined instruments that yield statistical data. Quantitative research is frequently referred to as hypothesis-testing research. Studies begin with statements of theory from which research hypotheses are derived. Then an experimental design is established in which the variables in question (the dependent variables) are measured while controlling for the effects of selected independent variables. Subject included in the study are selected at random is desirable to reduce error and to cancel bias. The sample of subjects is drawn to reflect the population (Newman and Benz 1998).

Model of this study was developing based on TAM model with six factors are: Website Service Quality (WSQ), Website information Quality (WIQ), Website interface quality (IQ), Perceived Usefulness of purchasing online (PU), Perceived Ease of purchasing online (PE) and Behavioral Intention to purchase online (BI). Research model showed relationship between factors through hypotheses as figure following:

Leedy et. al (2001) claimed that hypotheses are constantly generated in the human mind as we work to understand day-to-day phenomena. By formulating a series of reasonable guesses of cause and effect we are able to understand and explore the events in our surrounding environment. A hypothesis is important because it guides the research. In this study, to examine the success of research model author was developing 9 hypotheses as following:

H₁: There is a positive relationship between Web Service Quality and Perceived Usefulness of purchasing online

H₂: There is a positive relationship between Web Service Quality and Perceived Ease of purchasing online

H₃: There is a positive relationship between Web Information Quality and Perceived Usefulness of purchasing online

H₄: There is a positive relationship between Web Information Quality and Perceived Ease of purchasing online

H₅: There is a positive relationship between Web Interface Quality and Perceived Usefulness of purchasing online

H₆: There is a positive relationship between Web Interface Quality and Perceived Ease of purchasing online

H₇: There is a positive relationship between Perceived Ease of Use and Perceived Usefulness of purchasing online

H₈: There is a positive relationship between Perceived Ease of Use and Behavioral Intention to purchase online

H₉: There is a positive relationship between Perceived Usefulness and Behavioral Intention to purchase online

A pilot survey was executed before conducting the main survey. The purpose of the pilot survey was to examine variables and constructs of study reliability or validity. The survey was sending questionnaires to respondent through email. The estimated size is 175 peoples. E-mail message was sent to the personal to invite him (her) to take the survey. The message contained a brief description of the study objectives and asked them to participate in the survey by accessing the online survey by Google Docs Survey Tool or by sending questionnaire directly. A reminder e-mail message or a phone call was sent after one week from sending the first one.

The questionnaire concentrates to survey object such as e-commerce business manager, e-seller and e-customer in Hanoi, Danang, Ho Chi Minh city in October and December 2017. Questionnaires include 39 questions divide into two parts: Part 1: General information on the subjects of the survey: includes 6 questions containing basic information about the participants.

Part 2: The information related to Online B2C including 33 questions was designed as 7 point Liker-type scale where (1 = Strongly disagree; 2 = Disagree; 3 = Somewhat disagree; 4 = Neutral; 5 = Somewhat agree; 6 = Agree, and 7 = Strongly Agree).

Reliability refers to the extent to which a scale produces consistent results, if the measurements are repeated a number of times. The analysis on reliability is called reliability analysis. Reliability analysis is determined by obtaining the proportion of systematic variation in a scale, which can be done by determining the association between the scores obtained from different administrations of the scale. Thus, if the association in reliability analysis is high, the scale yields consistent results and is therefore reliable. In this study, author used reliability test of the items for measuring the constructs, to ensure that the measurement scale we designed for our questionnaire are highly representative of each variable, the Cronbach’s α is used.

Validity implies precise and exact results acquired from the data collected. In technical terms, a measure can lead to a proper and correct conclusion and result from a sample that can be taken as a valid conclusion about the population. In this study, author was apply pilot test for evaluate validity of variables and constructs before perform survey widely with larger participants in some difference area. In this study, after pilot survey, author run SPSS statistic to test variables and construct validity, all items in study are valid.
