INTRODUCTION
1. Necessity of the research
Hanoi is the leading political center and is one of the economic, cultural and
scientific centers of the whole country. In the past years, the strong development
of many forms of supermarkets has contributed to change the face of the city
towards the civilized and modern . Besides the general business supermarkets
serving the various demands of the different customers, has increasingly
appeared the specialized business supermarket on the fixed commodities or
commodity groups .
The specialized supermarket is a very specific business because it is the
product and services mixture. Goods in the specialized supermarket are imported
from the same suppliers. Most of the current commodities of the specialized
supermarket are similar . Therefore, the difference among the specialized
supermarkets is not the goods quality but is the service quality. The services of
the specialized supermarket are not only the normal sales services as other
retailer types but also the services arising from the goods characteristics of the
specialized supermarket beside the services that the specialized supermarket
provides to meet the demand of consumers.
To improve competitiveness and attract customers, thereby increase sales,
expand market shares and establish a strong foothold in the market, each
specialized supermarket is not only interested in the brand, origin, quality and
price of the goods but also pays special attention to expand the service types and
improve the service quality. The competition among the specialized
supermarkets is not only the product quality but also the service quality which
the specialized supermarkets provide
Unfortunately in fact, the specialized supermarkets do not always pay
adequate attention to this. The reports on consumer’s satisfaction also indicated
that although consumers are willing to pay more for higher service quality
corresponding to the quality of the goods that they purchase. However, the
service quality of the supermarket did not meet the customers’s expectations
(According to Thanh Nien in 2000; Commerce in 2005, 2006, 2007, 2009,
2010, 2012).

In Vietnam, according to the Author's knowledge until now there are two
researches on the service quality and the service quality constituent elements in
the supermarket: The first research, "Service quality, satisfaction, and loyalty of
the supermarkets in Ho Chi Minh City"(Author Trang Nguyen,in 2006). The
second research, "Factors affecting the quality of retail services in the
supermarkets in Ho Chi Minh City" (Author Nhat Nguyen,in 2007). Two studies
had different conclusions about the component elements of service quality in the
supermarkets and were carried out in Ho Chi Minh City.
Therefore, the research on the service quality of the specialized supermarket
will have major theoretical contributions: (1) Clarify the theoretical issues about
the specialized supermarket and the service quality of the specialized
supermarket, (2) Identify the component elements and the assessment &
measurement methodology of the service quality of the specialized supermarket.
(3) Build the study model on the service quality of the specialized supermarket
to continue the studies in other cities in Vietnam.
Starting from the necessity in the practical operation of the specialized
supermarket in Hanoi city, the necessity of the theory of the service quality of
the specialized supermarket, the Author decided to choose the topic "The
service quality of the specialized supermarkets in Hanoi city " that is the
doctoral research topic.
2. Research objectives of the thesis
The research objective of the thesis is to find the answers of five study
questions:

CHAPTER 1: RESEARCH OVERVIEW
4. Research results of the thesis
1.1.1 Concept of service quality
Through the research, the Author has contributed some new knowledge about
the theoretical and practical aspects in business administration of the specialized
supermarket and in state management on the specialized supermarket.
When talking about service quality, without fail, we have to mention the huge
contribution of Parasuraman and his associates (1985, 1988, 1991). Parasuraman
and his associates (1988, page 17) defined service quality as "the difference
levels between the customer’s expectations for the expected services and their
perceptions about the experienced services". These Authors initiated and used
the qualitative research and the quantitative research to build and test the
component scale of service quality (called the SERVQUAL scale) [15, page 58].
1.1.2 Components of service quality
New theoretical con tributions: The thesis has new theoretical contributions
on service quality : (1) Develop and test the research model of the service
quality of the specialized supermarket. (2) Determine the component factors,
observed variables and measurement scale of the service quality of the
specialized supermarket. (3) Seek out new component factors of the service
quality of the specialized supermarket in Hanoi.
1.1 Service quality
On the practical aspect: the thesis has some contributions: (1) Find out the
expectations, perceptions and gaps of the service quality of the specialized
supermarket in Hanoi city. (2) Determine the causes of the weakness of service
quality. (3) Provide solutions for the specialized supermarket to improve the
service quality of the specialized supermarket to enhance competitiveness, more
satisfy consumer’s demands. (4) Make recommendations to the state
The SERVQUAL is a model measuring the customer’s evaluation levels
based on the most important elements. The assessment was generalized and
based on the gaps between the customer's expectations of the expected services
and the customer’s practical service use. In the 1st research of Parasuraman and
his associates (in 1985), the service quality comprise ten factors . The
SERVQUAL continue to be adjusted and tested in many different types of
services. In 1988, the research of Parasuraman and his associates collapsed the
component factors. Finally, The SERVQUAL consists of 22 observed variables
measuring five components of service quality such as: (1) Reliability, (2)
Tangibles (3) Responsiveness, (4) Assurance and (5) Empathy.

1.2.1 Concept of specialized supermarket
According to Regulation of supermarket and commercial center of Vietnam
Ministry of Trade (now the Ministry of Industry and Trade) in 2004, specialized
supermarket is the modern type of store; specialized business; divers &
abundant commodity structure, quality assurance; meet the criteria of business
area, technical equipments and management skills, business organization;
civilized &convenient service modes to satisfy customer’s demand of goods
procurement . [3, page 3].
1.2.2 Classification of specialized supermarket
Under regulations, specialized supermarket is evaluated based on five
criteria: (1) business area, (2) the list of goods business, (3) buildings and
facilities, (4)
warehouse system and technical equipments, (5) goods
organization.

1.2.3 Service types of specialized supermarket
The specialized supermarket include three main types of services that are: (1)
Sales services; (2) Specialized goods services ; (3) Value added services of
specialized supermarket as a supplemental industry.
5
Firstly, Sales services : These are the popular services like other retail
services such as a free parking services, membership card issuance with
member benefits, sales promotion program on holidays and birthdays, customer
gratitude programs, free delivery services, goods returns services in regulated
time.
Secondly, Specialized goods services: These are the services associated with
the nature of goods. The main reason for these service types is because
specialized supermarket provide narrow and deep product ranges, most
customers can not fully understand the products. At the same time, with the
progress of technology, these products are continuously renewed therefore
consumers can not update the product as much as the specialized supermarket.
For example, a specialized supermarket on living room furniture will be an
expert on sofas and carpets such as tapestries, floor carpets, cleaning carpets .
Therefore, specialized supermarket must provide many services related to the
product. This is a type of characteristic service of specialized supermarket.
Thirdly, Value added services of specialized supermarket : It may include
services of warranty period extention after expiry of manufacturer’s warranty
period. Based on receipt manufacturer’s specifications and understand
customer’s demand. The specialized supermarkets provide additional warranty
services, product maintenance at home, complementary product services from
different suppliers, Services of old products shopping and new product
replacement for customers who want to upgrade their products.
2.3
Researches on retail service quality in the world and in Vietnam
Dabholka, Thorpe and Rentz (1996), based on qualitative research, previous
service theory and the SERVQUAL scale, gave five basic components of retail
service quality: 1 / Tangibles (physical aspects), 2 / Reliability, 3 / Personal
interaction, 4 / Problem solving and 5/Policy. Mehta and Associates (2000)
have found that component elements and scale of retail service quality (RSQS)
are more suitable to the retail environment "more goods than services," such as
supermarket.
6
Research ( Trang Nguyen, 2006) used the scale of retail service quality
(Dabholka & CTG, 1996) and adjusted , and additional components of service
quality of supermarkets in Vietnam. Research: "Elements affecting quality of
retail services in supermarkets in Ho Chi Minh City" (Nhat Nguyen, 2007).
These researches just studied one or some retail types and by scientific articles.
This is an important suggestion for further researches.
Also, the theory “Life cycle of store” has shown that: the traditional
retailers and the first generation supermarket have been losing their positions in
the market and have to find innovation to adapt competitive conditions.
Specialized stores and supermarkets are on the growth phase. The majority of
specialized stores and supermarkets are both acting internationally.
Study of Levy and Weitz (2009) has shown that there are 6 elements

5.1 Strengths and weaknesses in service quality of specialized supermarkets
in Hanoi city.
From results on service quality gaps of specialized supermarket, As we see,
factors having the largest gaps are “problem solving” (1.11) and personal

5.2 Causes of weaknesses in service quality of the specialized supermarkets
in Hanoi city.
From analysis of causes of three component elements having the largest
gaps, 10 observed variables have the gaps which are larger than 15 observed
variables with the lowest expectations, 5 observed variables have the lowest
perceptions. Author carried out synthesis of causes of weaknesses in service
quality of the specialized supermarkets in Hanoi city. It may include 3
following main causes.
The first cause is due to a band of staffs of specialized supermarket . In
particular, due to the cause of knowledge, skills and working attitude of staffs in
specialized supermarkets. Thus, specialized supermarket need to have solutions
to improve staff’s skills and motivation.
The second one is due to management skills of specialized supermarket.
This cause is derived from ability to manage the list of goods that does not meet
specialized business, displaying goods is not synchronized in order that
customers can choose according to criteria of specialized business of
supermarket.
The third one is due to ability to understand customer's expectations. In
particular, specialized supermarket does not have much information about
ptarget customers. Therefore, supplied services are not suitable to customer’s
real expectations.
are created from oral information about specialized supermarket. Apart from
advertisement publications given by specialized supermarket, Specialized
supermarket need to study 3 remaining information sources in order to
understand customer’s expectations.
5.5
Solutions to enhance staff’s working skills and motivation
Specific solutions to improve staff’s skills are training on products and
training on sale skills and customer care and working attitude supervision and
programs to create staff’s motivation.
5.6 Solutions to improve management skills of specialized supermarket
Solution to enhance management skills is also a factor to improve service
quality of specialized supermarket. Solutions should be focused on three key
issues: (1) Goods management skills based on products, (2) retail price
management skills, and (3) goods display management skills in order that
consumers can easily choose goods in specialized supermerket.
5.7 Some recommendations to state management bodies on service quality
of specialized supermarket.
Recommendations to state management bodies on building standards of
service quality of specialized supermarket. Recommendations on support to
enhance staff’s skills. Recommendations on dissemination to raise awareness
about service quality as well as goods quality.
5.8 Limitations and further research directions
5.4 Solutions to study customer’s expectations
As same with other studies, Author’s research also has some limitations: (1)
research scope only is in Hanoi city, (2) research object only is specialized
supermarket. Therefore, this research also opens a further research direction for
example research on retail service quality such as general supermarkets, Big
supermarkets, commercial centers, elective service stores. . . Research on service
