Chapter One: Introduction

1. Background
1.1. The Internet in Vietnam
It has been more than one decade since the Internet started to have been used in
Vietnam. Vietnam connected the world in 2000, the Internet users was a small figures,
just 0.3% of the population in 2000. However, the Internet is growing fast, much faster
than in any other Asian countries in 2011. Over the last ten years 2000-2010, Internet
usage has grown by 12.4 times in Vietnam. This is the highest level of penetration in
the Asian countries. After five years from 2000, this number was up to 12.8%; and
17.9% in 2007; 24.0% in 2008; and 25.7% of Vietnam population in 2009.
Impressively, este et al. (2012) suggest that a large number of Vietnamese Internet
users accounted for 30.8 million at the end of Feb 2012, equivalent to 34% of Vietnam
population. More and more people are online and in Vietnam, they spend a massive
amount of time on the Internet. There is a huge, targetable population of consumers
online. As to Feb 2012, 30.8 million Vietnamese people can be reached on the Internet,
with a strong growth every year. In addition, these are not just the teenagers, but also
more and more also their parents and in general, the household decision makers, an
interesting target audience for marketing activities. They are also increasingly
comfortable with making purchases online.


2. Statement of purpose

protection, security protection, perceived risk, and perceived benefits) have impacts on
customer trust in online in shopping in Vietnam.

3. Research question
Is customers’ trust affected by perceptions about privacy, security protection,
perceptions about the risks and benefits during the transaction on the Internet.

4. Significance of the study
In terms of theory, this study provides an empirical understanding role of factor
trust towards online shopping; And in terms of practice, this study presents strategic
implications and directions for the development of online shopping in Vietnam.

5. Scope of the study
The study focuses on collecting people having experience in the online shopping
Ho Chi Minh City. The city is selected due to the highest Internet penetration rate. Este
et al. (2012) suggest that the Internet penetration rate is more than 50% the population
have used the Internet already in urban Vietnam. The city is higher than the average
rate of 50% of the population with the rate 62% in 2011.

6. Structure of the study
The thesis consists of five chapters. Chapter 1 introduces an overview of the
background, statement of purpose, research question, the significance of the study, and
scope of the study. Chapter 2 reviews existing literature on trust, online customer trust,
and the four antecedents of trust. These literatures summarize briefly the knowledge of
recent studies, describes the conceptual model, and hypotheses. Chapter 3 presents who

trusting intentions (McKnight et al., 1998). The others conceptualize trust as general
beliefs in e-commerce contexts that leads to behavorial intentions (Gefen, 2000); as a
combination of intergrity and caring that leads to an increase in behavioral intentions to
vulnerability (Javenpaa and Tractinsky, 1999); as a specific belief dealing with
benevolence, competence, and intergrity that results in trusting intentions (McKnight et
al., 2002).
However, the distinction between trust as a set of specific and general belief is
primarly happened dealing with interpersonal trust in organizational settings
(McAllister, 1995; McKnight et al., 1998). However, this distinction is seldom occured
in economic transaction settings because the definition of trust is used in these contexts
is an extension of trust definition rather than the original definition of interpersional
trust (Hosmer, 1995; Williamson, 1985). Consequently, some researchers stated that
actual behavior in ongoing economics alliances is a proxy for trust, defined in that

6
context as confidence or an overall belief (Gulati, 1995). This study has adopted the
conceptualization of trust as a set of specific beliefs because it deals with going
economic relationships (Crosby et al., 1990; Doney and Cannon, 1997; Ganesan, 1994;
Schurr and Ozanne, 1985) and this set of specific beliefs is most widely used in the
literature. Therefore, Trust as a feeling (Rempel et al., 1985) has been previously
studied in the context of interpersonal relationships. It is arguably irrelevant to business
transaction. (see Table 2.1)

1.2. The importance of trust in e-commerce
Trust plays such an important role between sell site and buy site, especially these
containing the element risk including interacting with an e-vendor (Reichheld and
Schefter 2000). It is one’s belief that the other party will behave in a dependable (Kumar
et al., 1995a), ethical (Hosmer, 1995), and socially appropriate manner (Zucker, 1986).
Trust is also deal with fulfillment (Luhmann, 1979; Rotter, 1971). Lack of trust is one of
the most frequently cited reasons for consumers not shopping on the Internet (Lee and
Turban, 2001). Trust becomes a serious issue in Internet shopping because there is an
absence of proven guarantees. Jarvenpaa and Tractinsky (1999) and Reichheld and
Schefter (2000) suggested that online customers generally stay away from e-vendors who
they do not trust on.

2. Trust antecedents identified in the literature
This study builds upon previous research by combining several trust antecedents in
order to provide insights to online firms conducting business in different parts of the
world. The model suggests that trust in Internet shopping is directly affected. The model
