Trang 4Abstract
During the last decade of the 21st century, internet shopping had grown in a surprising speed
With the fast development in internet and technology, people are no longer need to go out for
their shopping since they can use retailing for almost everything they need Although
e-shopping has its huge potential to even replace the traditional way of e-shopping, it has its own
problem It is when people only use website for reference, and then they come directly to the
physical store to pick up their items
This research is conducted to find out the critical factors that can measure the customers’
intention to use e-retailing From several studies about this topic, especially the theory of
reasoned action (TRA), there are four factors may affect to the customer’s intention They are
trust, subjective norm, website quality and perceived risk in using credit card
In order to conduct the research, a sample size of 150 questionnaire about clothing products are
collected with respondents are office employees in Ho Chi Minh city Then, the data are
analyzed by reliability test, EFA and multiple regression analysis
Result of the thesis shows that the customers’ intention to use e-retailing is impacted only by
trust and subjective norm Therefore, it is suggested that owners of the business should try to
gain trust of their customers and encourage people to shop by groups
Since this research only focused in fashion products in Ho Chi Minh city, furthers studies in
this field should be conducted for other types of products and in other provinces in Vietnam to
find out the general model for Vietnamese e-retailing

INTRODUCTION 1.1 Research background
E-retailing, also known as online shopping, internet shopping or e-shopping, can be
explained as an electronic commerce when buyers and sellers virtually meet others through a
web browser Unlike traditional shops that require physical locations, physical security services
and specific timeframes to operate, internet shops need none of those requirements Customers
can access to the shop from anywhere and anytime they like as long as they have internet
connection and an appropriate device like a computer, a tablet or a smartphone Since people
are more and more busy with their job and internet has been widely and easily accessible,
e-retailing has “redefined business and customer relationships, business processes, even
sometimes restructuring the whole industry by providing new distribution channel, new
delivery methods, new payment methods and new medium for communication” (Dogerlioglu
and Cosgun, 2012) People had forecasted that in 2014 US e-retailing business can earn up to
$291 billion dollars in sale (Trends & Data - Internet Retailer)
With the tremendous opportunity to grow and a very promising market to exploit, retailing has been attracting many scholars and experts to make researches in order to become
e-successful in this new method of selling products As the results of that, many factors had been
explored to contribute to a successful online business In 2009, Liao and Shi found that in Hong
Kong market, where people tend to shop in groups, social influence should be a big factor that
influence on the shopping behavior Even internet retailing does not require people to go out
for shopping, owners of the e-retailing business still need to think of ways like spreading
information as wide as possible, focusing on group buying, encouraging group-buying
Trang 10effortless when customers interact with the web pages can create the favorable shopping
intention Besides the attitude towards e-retailing, Gefen, Karahanna and Straub (2003) added
that customers’ trust played a significant role in increasing customers’ intention to shop online
They also proved that trust in e-vendor can be gained when people know that shop owners earn
nothing more by cheating, a shop is safe to make transaction and the website is optimized to be
friendly and easy to use
As mentioned above, since e-retailing has been developed with a rocket speed, there are thousands of researches have been made only for gaining customers’ intention towards internet
shopping However, not many of them were made specifically for Vietnamese market
Therefore, it is an interesting topic to discover and study
1.2 Problem statement
In Vietnam, although traditional retailing is still playing a significant role, internet shopping has been developed so rapidly and become more important According to Phan
(2013), 36% of Vietnamese people are using internet and they generated a 700 million US
dollars in revenue for e-retailing Although e-shopping only accounted for 0.3 to 0.5% of the
total retailing revenue in Vietnam (according to Green Global, 2013), it can increase up to 2
times - 1.3 billion US dollars in 2015 (according to the Ministry of Industry and Trade)
However, internet shopping has its own problem It is because many of the internet users only
go to the websites to find information, the price and comments about the products but they
hesitate to make the paying transaction or products reservation (Ting & Lim, 2012)
Vietnamese customers would rather go direct to the shop and buy the things they saw on web
As the result of that, e-shopping as they know is nothing but an advertising or marketing
Trang 11successful in this field However, I fear that doing business like that will lead to failure for most companies Investing in e-retailing requires much more money than people think Moreover, life in Vietnam is not that industrialized that people have to go online for shopping
Therefore, Vietnamese e-retailing market is very challenging to small and medium businesses but it is also very promising with the prospect of fast developing and huge revenue
it can generate The problem is how an internet based retailing business can connect to the end
clients and persuade them to make transactions through their sites It is why the research was
conducted, to find and understand what significant factors affecting the intention of people to
use e-retailing
1.3 Research objectives
As discussed in Section 1.1, e-retailing business is not only very promising in Vietnam but also very challenging In order to be successful in this field, people firstly need to discover
what factors can drive the shopping intention of clients Therefore, this research aims to:
- Identify critical factors affecting customers’ intention to use e-retailing
- Identify the level in which each factors affecting customers’ intention to use e retailing
1.4 Research questions
There are two questions to be answered to solve the problem identified in Section 1.2:
- What are critical factors affecting customers’ intention to use e-retailing?
- What is the level of impact of each factors affecting customers’ intention to use retailing?
e-1.5 Research scope
First of all, surveys questionnaire are collected only in Ho Chi Minh city – this is the most crowded city in the country and also known as the biggest economic center in Vietnam
Second, only clothing products were researched It is because clothing products are easy to
store and deliver (compare with grocery or electronic products) Besides, clothing products are
fast to produce and people tend to change their clothes so many times during a year Especially,
Trang 12clothing products are manufactured by seasons, even when a cloth is quite new, people still
change it to others when season changes Finally, the research focus in office employees since
they spend lots of their time sitting in front of a computer, have the opportunity to use internet
almost daily and have good knowledge about computer or internet activities
1.6 Research significance
Because of the development of e-retailing, customers now have more choices to buy their needs They can choose either going to the shop to pick up the products when they have time or
sitting in front of an internet devices and performing a transaction to get their products
E-retailing therefore brings benefits not only to consumers but also to sellers People can shop
whenever they like and sellers can sell almost 24/7
This research aims to discover the significant factors affecting customers’ intention to use e-retailing in Vietnamese context Results of the thesis may contribute to the academic
knowledge in terms of Vietnam e-retailing market and Vietnamese consumers’ decision
factors It can help business to understand what affects to customers’ intention when they try
their services Therefore, they can define a better strategy and customize their service to have
better e-shopping experiences to attract to more customers For a general picture, the research
may contribute, to some extent, to develop the Vietnamese e-retailing market in the future
1.7 Research structure
This research consists of five chapters First chapter is the introduction that presented the overview about the topic, the purpose of the research and the approached way to solve the
research’s problem Next chapter is the literature review where prior studies about internet
shopping had been reviewed in order to propose the conceptual model and hypotheses Chapter
3 is about the research methodology in which the research process is discussed Then, Chapter
4 about data analysis illustrates the testing of survey data In Chapter 4 also, results of the
proposed model are presented Final chapter is about conclusion and recommendations where
research findings and managerial implication are discussed In this chapter, the limitations of
Trang 13the research are mentioned in order to provide the directions for further researches about
customers’ intention to use e-retailing the future
Trang 14the most affected is the retailing business Traditional method of selling products by displaying
all items in a physical store and waiting for customers to come and pick them up is endangered
since many customers prefer to sit in front of their electronic devices and buy the products they
need right on their devices over the internet In other words, many people would rather use
e-retailing than travel to the real shop Therefore, this kind of shopping is attracting not only
buyers and sellers but also researchers because of its convenience, speed, 24/7 services, full of
products’ detail and reviews By definition, e-retailing, or internet shopping, means that buying
and selling processes are all made through internet Although many of us do not have the habit
of buying online, the reality is that we do spend lots of time searching for products’ information
and specifications on the internet According to ReachLocal (2012), 21% of the time people
spending on the internet is for searching only and 61% of internet users research for their
products online (Interconnected World: Shopping and Personal Finance, 2012)
Andam (2003) has defined e-retailing as a form of e-commerce - “a range of online business activities for products and services” E-retailing can be understand as a B2C e-
commerce, a commerce between companies or shops and customers, it involves customers’
purchasing both kinds of goods (physical and informational) and receiving them over an
electronic network (Andam, 2003)
Trang 15Back to the mid of 1990s, the founding of Amazon and eBay can be named the origin of retailing The early success of the two companies signaled the huge changes could happen in
e-the way people run e-their business Since buyers know that e-they can save lots of time traveling
to see and buy a product, they can stay at home, use some clicks and have products delivered to
their home the next day or two That was just so simple and convenient Consumers using
internet shopping not only save time but they are also allowed to save cost since they have
chances of choosing the most competitive products among internet sellers Not long time after
the Amazon and eBay succeeded, many internet based retailers were founded and then they
completely redefine the retailing industry According to Deloitte, e-commerce accounted for a
significant share of total retail revenue for the top 50 e-retailers in fiscal year 2012, accounting
for nearly one-third of company sales on average
Not only brings huge benefits to consumers, but e-retailing also makes significant improvement to the resellers Andam (2003) stated that e-retailing can reduce the market
barriers since the cost of setting up and operating a website is much cheaper than building a
traditional “brick and mortar” shop He also said that for a country with robust internet
population, delivering informational goods (electronic books, digitized contents or software)
becomes significantly potential
2.2 Customers’ intention to use e-retailing
Defined by Ajzen (1991, p.181), an intention is ‘‘indicators of how hard people are willing
to try, of how much of an effort they are planning to exert” In another study, intention was
referred to” the individual’s assessment of the subjective probability that people will perform a
particular behavior in the future”(Söderlund & Öhman, 2003, p.54) In e-retailing context, Bai,
Law and Wen (2008) stated that purchasing intention is a primary result of pre-purchase
satisfaction Chen, Hsu and Lin (2010) even confirmed that the online shopping intention is the
significant predictor of actual buying behavior Applying to this research, customers’ intention
to use e-retailing is defined as the expectation or intent of customers to perform the online
purchasing in the future
Trang 16Theory of reasoned action (TRA) is one of the famous models that widely used to predict the behaviors of customers based on their behavioral intention Derived from numerous
researches and theories about customers’ attitude, TRA model was proposed by Ajzen and
Fishbein (1975 & 1980) It suggests that the immediate antecedent of a behavior is the intention
to perform the behavior in question (Fishbein and Ajzen, 1975) It can be seen that the stronger
the intention people want to try something, the higher the possibility that they may actually do
it In the context of this research, customer’s intention can be defined as the intent or
expectation of a customer to purchase products via internet channels There are three key
factors to form the construct, they are two independent factors that are used to define the
behavioral intention First factor is person’s attitude and the second is subjective norm
- Person’s attitude Generally, attitudes can be understood as the beliefs about the results of performing an behaviors and the evaluation of those expected outcomes
- Subjective norm In a simple form, subjective norm can be defined as the opinion
of one person on how he/she thinks others should view them if they perform a behavior
The summary of TRA model can be expressed as the Figure 2.1:
Alternatively, in a simple form, TRA can be written as a formula:
BI = (AB) W1 + (SN) W2BI: Behavioral intention AB: Attitude toward performing a behavior SN: Subjective norm related to performing a behavior W: empirically derived weights
(Dillard & Pfau, 2002 )
Trang 17Figure 2.1 The theory of reasoned action
(Vallerand et al., 1992)
Because of the possibility to predict the people intention towards a behavior, TRA had been used in a variety of contexts and industries For example, Vallerand, Deshaies, Cuerrier,
Pelletier and Mongeau (1992) had used TRA to research about the moral behavior and they
found that both attitude and subjective norm positively supported the model Particularly,
attitude did prove to be more important to predict a behavior than subjective norm
Alternatively, another research made in Thailand by Chuchinprakarn (n.d.) also found that
attitude and subjective norm did influence the customers’ intention to shop on-line
In this thesis, in addition to the TRA model, other models and researches are included to help explaining the customer’s intention In details, internet retailing quality (IRQ) and
customers’ perceived risk in using credit card are added to form the research model
As defined in Section 2.1, e-retailing is a new way of purchasing products when consumers only need an electronic device and internet connectivity to perform a transaction Since internet
Trang 18shopping is also a service, the concept of quality applied in this context is similar to
conventional service quality As such, e-retailing quality should incorporate all of the
functional aspects of the service process as well as the technical ones of the service outcome
(Gronroos et al., 2000; Collier and Bienstock, 2006) According to Parasuraman et al (2005,
p.217), internet retailing can be defined as “the extent to which a web site facilitates efficient
and effective shopping, purchasing and delivery” In other to measure the e-retailing quality,
there are number of scales had been created, some of them are summarized in Table 2.1
As seen from the Table 2.1, one of the most important dimensions to measure e-retailing quality is the website quality Website quality is a significant factor in internet shopping since
“the customers’ perceptions of website quality positively impact their intentions to use a site
and directly affect purchase intentions” (Chang, Kuo, Hsu & Cheng, 2014, p.256) In a simple
way, website quality is defined by its content and user interface A high quality website needs
to provide relevant and useful content along with its good and easy user interface It is so
simple since almost all actions customers have to make to perform a purchase are placing on a
web browser Therefore, in this research, instead of using IRQ in general, website quality will
be measured to examine the customers’ intention to use e-retailing
Perceived risk is defined as uncertainties of possible negative consequences of using a product or service (Chang, Kuo, Hsu & Cheng, 2014) In this research, perceived risk in using
credit card refers to the uncertainties of people that they may lose money when purchasing
products online The financial loss due to credit card fraud is a primary concerns among online
customers (Dai, Forsythe & Kwon, 2014)

Trang 202.3 Factors impact to the customers’ intention to use e-retailing
2.3.1 Research model
Based on the TRA model and other researches that explained the customers’ intention toward a behavior, the research model is proposed in Figure 2.2 This model contains four
independent factors, including trust, subjective norm, website quality and perceived risk in
using credit card, that affecting the intention of customers to purchase product online In
addition, three more demographic variables were used to test whether the characteristic of
customers have any significant difference on their intention

2.3.2 Trust
According to the TRA model (Ajzen & Fishbein, 1980; Fishbein & Ajzen, 1975), the best predictor of a future behavior could be the behavioral intention One of the influences on the
intention is the person’s attitude toward performing the behavior Generally, attitudes can be
understood as the beliefs about the results of performing a behavior and the evaluation of those
expected outcomes It “represents the person's general feeling of favorableness or
unfavorableness for the behavior in question" (Ajzen & Fishbein, 1980) So the more
positive people believe in the behavior, the more likely they intend to perform it
However, since personal attitude is a very wide range to study, the author had narrowed it down by using only one of its components So, trust was considered as one of the best choices
Recently, trust had been widely discussed as a key factor for a successful online business In
term of a business, trust is defined as “the consumers’ belief and expectation that e-sellers are
reliable and will perform their obligations faithfully” (Chuchinprakarn, n.d.) Trust is an
important factor affecting consumers’ behavior and it may contribute to the success of
technologies adoption such as e-commerce (Chen & Barnes, 2007; Holsapple & Sasidharan,
2005; Goles et al., 2009; Yang et al., 2003) It can be seen that buyers are more likely to make
transactions on the internet if they know that sellers are trustworthy and reliable Unlike
physical store that people can come and try the items, online shops have almost no thing to
guarantee customers that their items are exactly what people can see in their websites Because
of that, customers’ trust even plays a more critical role to the intention of purchasing online
then buying by traditional method According to a report from Yahoo Finance in 2012, the top
three counterfeited products in America are all related to clothing items, i.e wearing apparels
and accessories, watches and jewelries, handbags and wallets It is said that one of the source to
deliver fake products is the online shop since people can not touch the real items but only read
their info on the websites Although the availability and easiness of buying a product is
Trang 22changing since the booming of internet usage, there is an old-fashioned value that every
business needs to maintain – it’s customer’s trust
Since trust could significantly effects on e-retailing, first hypothesis is proposed as:
H1: Trust has a positive effect on the customer's intention to use e-retailing
2.3.3 Subjective norm
In a simple form, subjective norm is the opinion of one person on how he/she thinks others should view them if they perform a behavior In a research, they define subjective norm as a
social factor referring to the perceived social pressure to perform or not to perform the behavior
(Ajzen and Madden, 1986) Normally, a social circle of a person includes his or her peers,
which constitute siblings, friends and acquaintances (Pilgrim & Lawrence, 2001)
According to Liao and Shi (2009), the influence from a social group should not be ignored since the surrounding may highly affects to individuals to perform a behavior Especially in
Vietnam where people are more collectivistic than individualistic, social norm may even has a
more important role impacted to the intention of people Clasen and Brown (1985) stated that
an individual who belongs to a group may adapt his habits according to that group, he then
complies with the dominant traits of that group to form his own trait, intentionally or
unintentionally
Therefore, it is a reality since we know sometimes people are very positively affected by subjective norm They may not be favorable to a behavior or consequence but they do want to
perform it because they believe in their referents It is the time when people feel motivated to
perform a behavior According to Davis and Vekatesh (2000), working environment positively
affects to the individual behavioral intention Lee, Cheung, Sia and Lim (2006) also found that
the positive informational social influence could enhance the relationships between customers’
attitude about internet shopping and their intention to shop
In this research, the social norm that affects the customers’ intention to use e-retailing is referred to the customers’ co-workers and friends People working in the office meet their peers
very frequently, almost day-to-day basis so they are likely to be more up to date with new
Trang 23trends in fashion products As discussed earlier in this section, Vietnamese people are
collectivistic, like many other Asian countries, so they have a tendency to follow others An
office employee may feel very isolated if he or she can’t catch up with the new trends in his/her
office
At such, social influence is believed to have significant impact to the customers’ intention
to shop online Therefore, the second hypothesis is proposed as:
H2: Subjective norm has a positive effect on the customer's intention to use e-retailing
2.3.4 Website quality
Pinho et al (2011) was successful to discover the influence of website quality characteristics on intention of users in applying online services They found that factors
including research facility, provides detailed information, privacy and security, interaction
facilities and contacts, speed and facility of access, availability of relevant downloads, reliable
and up-to-date information are the most important qualifications of a website The research
results presented that website quality increases intention of the users
In another research of Bai, Law & Wen (2008) about the direct effect of website quality on customer satisfaction and purchase intention in China, they concluded that customer
satisfaction and purchase intention are directly influenced by website quality Jeong, Fiore,
Niehm, and Lorenz (2009) found that rich website design elements can enhance the users’
interest and experiences, which in turn increased their intention to purchase
Wolfinbarger and Gilly (2003) stated that when customers interact with an online store they prefer to do their shopping through a technical interface and do not need the existence of any
employees Therefore, the design of the website, which acts as the interface, would play an
important role in influencing customer satisfaction
Therefore, hypothesis three is proposed as:
H3: Website quality has a positive effect on the customer's intention use e-retailing
Trang 242.3.5 Perceived risk in using credit card
Perceived risk in using credit card is the uncertainties of financial loss when using credit card for online purchasing Consumers are worried to give their personal information
particularly data on financial status and credit facilities to the internet because of the fact that
there is no direct eye-contact and thus, consumers are concern about unauthorized use of their
private information (Grabner-Kraeuter & Faullant, 2008)
Chakravorti (2003) stated that people are hesitate to make their online purchasing by credit card since they are afraid that they cannot afford their payment when the card is on due date It
is a real risk because people may over consume their money without having control on their
balances It can lead to financial debt in the worst case when consumers have to pay additional
fee and interest In a research conducted by Salam, Rao and Pegels (2003), they found that
consumers will highly stop making transactions over internet if for some reason, the potential
loss of finance is too high They stated that “the consumer’s perception of risk associated with
the transaction will tend to predominate in his/her decision to engage in a transaction”
At the result of that, the hypothesis four is proposed as:
H4: Perceived risk in using credit card has a negative effect on the customer's use e-retailing
2.3.6 Demographic variables
In testing the customers’ intention use e-retailing, this research also included some demographic variables The purpose is to know whether characteristics of consumers have any
significant effect on their intention to perform the internet shopping Three variables are chosen
to investigate, they are gender, income and age
In 2002, Burke (as cited in Suki, 2011) stated that demographics (gender, age, education) are key moderators in the online shopping environment Whitely (1997) also confirmed that
males are more positive and less anxious about technology innovations, which are very likely
to happen in the world of online retailing As growing older, people are less likely to access
online information and using websites for shopping (Suki, 2011)
Therefore, the fifth hypothesis is proposed as:
Trang 25H5: Characteristics of customers have significant difference on their intention use e-retailing
In summary, this chapter is written to review researches conducted in the past to find the model that can predict the customers’ intention to use e-retailing By revising TRA model and
other studies, four factors were chosen to form the research model They are trust, subjective
norm, website quality and perceived risk in using credit card From the four factors, only
perceived risk in using credit card has the negative impact on the customers’ intention
In addition, three demographic variables were added to the model to find out if gender, age
or income affect to the customers when they choose to shop online
Trang 26The research process is described in Figure 3.1:

Lastly, reliability test, EFA and multiple regression analysis were used to test the measurement
scale and research hypotheses
3.2 Measurement scale of factors
First part of the questionnaire consists of three demographic questions including gender, age and income of the respondents Then, respondents were asked to give their opinion about the e-
retailing in the next part consisting of 19 questions They would give their opinions about trust,
subjective norm, website quality, perceived risk in using credit card and the intention to use
e-retailing In this part, questions were measuring in interval five-point Likert scale – they are (1)
– Totally disagree, (2) – Disagree, (3) – Neutral, (4) – Agree and (5) – Totally agree
Trust (TR): there are five statements to ask to measure the customers’ trust toward the
e-retailing shop, derived from Doney and Cannon (1997)
Subjective norm (SN): three questions are used to capture the information about this
variable, adopted from Liao and Shi (2009)
Website quality (Wb): measurement scales from Francis (2007) is used in addition with one
statement from the author, totally there are five items to measure this construct
Perceived risk in using credit card (PR): the perceptions of customers on using credit cards
is measured by three items, based on Liang, Lu and Tu (2006)
Intention to Use E-retailing (Int): four statements to ask to measure the customers’ intention
to use e-retailing, based on Lim and Ting (2012)

Trang 293.3 Pilot test
Before conducting the main survey, a pilot test was made At this stage, five people were chosen, from various companies and industries, to ask if they understood the survey clearly
without any explanation from the author The purpose of this part is to refine the questions
when it was translated to Vietnamese Feedbacks of respondents was used to enhance the
readability and quality of the questions Next, the questionnaire was refined after collecting
feedbacks of the pilot test from respondents
3.4 Data collection
Primary data of main survey was collected by sending out surveys to respondents via emails and direct paper All respondents are informed that their data would be kept
confidentially, any information without their permissions would not be public As written in
Chapter 1, respondents were all office employees worked in Ho Chi Minh city In this paper,
data were all collected in the period of mid July 2014 to August 2014
Since the number of questions in the survey are 19 (excluded the demographic questions), the total of respondents should be at least 95 (5 times than the number of questions) to ensure
that the data would be sufficient to run statistical analysis
In order to collect feedbacks, hard copy surveys are sent handedly to respondents to ensure that they would answer all questions completely For the electronic versions, questionnaire was
designed by using Google form Then, emails were sent to each respondents, all are office
employees, there is a link to the survey in that email
There were 200 surveys sending out in both types From the feedbacks received, there were
150 found to be usable The others had to be ignored due to some errors such people did not
complete 100%, people answered all questions with identical values, etc However, 150 is
considered a good number to be analyzed in term this research
3.5 Data analysis method
Collected data were coded before analyzing in SPSS software First, reliability test was done by examining the Cronbach’s Alpha of the constructs in research model Next, EFA was
Trang 30conducted to verify the validity of items in the constructs Then, multiple regression analysis
was used to test the research hypotheses After that, ANOVA analysis was used to test the
difference of demographic variables on the intention of consumers to use e-retailing
Pre-requisites of those tests are included in the next chapter when each test is illustrated
In summary, this chapter presented the process in which the research was conducted There are six steps that were performed from defining the research problem, literature review and
hypotheses, design questionnaire, pilot test, data collection to data analysis and results The
chapter also discussed the statistical methods used in testing measurement scale and research
hypotheses, including reliability test, EFA and multiple regression model
Trang 31Characteristics of the dataset were examined by the three demographic questions in section
1 of the questionnaire From the data collected, the author would summarize the data as below:
- Gender: 58 of 150 respondents were male, accounted for 39% The rest were female, accounted for the 61% of respondents
- Age: of the 150 people, only 3 are in the age of 18 to 22 years old (2%), 59% of respondents were in the age to 23 to 30 (88 people) 49 people (33%) were 30 to 40 years old
The rest 10 of people were above 40 years of age, accounted for 7%
- Income: in this category, most of people were asked to complete the survey had income lower than 15 million VND per month Of the three range below 15 million VND, the number
were almost equally distributed 32% of all people received less than 5 million VND per month
(48 people), 29% had 5 million to 8 million VND per month (43 people) and 41 people earned
8 million to 15 million per month (27%) The last 12% of total people could earn more than 15
million VND per month (18 people)
Summary of the sample characteristics is listed in the Table 4.1
Trang 32Table 4.1 Descriptive statistics of respondents
alpha number should be higher than 0.7 to be reliable In addition, a correlation of items among
a construct should be higher than 0.3 to indicate that those items are good components of the
factors Cited by Chong et al (2010), a coefficient ranges from 0.1 to 0.29 forms a weak
correlation among components, from 0.3 to 0.49 forms the medium one and above 0.5 forms a
strong correlation
Results of the reliability tests, included Cronbach’s alpha coefficients and correlation matrix are illustrated in Table 4.2
