INTRODUCTION
1. Research ideal
Accounting information includes financial and nonfinancial information. We
do not deny the significant role of financial information of companies in the investors’
decision making. However, in a developing society, the intense production of
enterprises leads to negative environmental impacts, labour exploitation to maximize
profit, regardless of adverse effects on the development of sustainable economy.
Therefore, since the 1990s, organizations created the concept of sustainable
development, thus the awareness of companies and stakeholders has improved in
terms of not only financial information but also nonfinancial information, which
includes information about environment, society, corporate governance, and other
nonfinancial information, changed from encouraging voluntary disclosure to
mandatory disclosure some types of nonfinancial information such as social and
environmental information. For example, when starting a project, besides providing
financial information like financial position, cash flow, payback period, profit, etc.,
companies must also disclose nonfinancial information of the project to stakeholders
such as its negative impacts on the environment, solutions for the pollution,
remuneration policy and unemployment resolutions for the local workforce. Only this

way, companies will provide overall and sufficient information to investors so that
they can make economic decisions.
Investors, especially international ones, are paying much attention to
nonfinancial information to have an insight in the value, prestige, and sustainability of
businesses. If companies do not attempt to lessen their negative impacts on the
environment and society, they will not be possible to get and retain professional
investors. Besides analyzing traditional financial indicators to make business
decisions, investors also analyze nonfinancial factors including environment, society
and corporate governance information for the decision making of investors.
Nonfinancial information disclosure has been applied for a long time in
developed nations worldwide in several forms with the guidelines like the Global
Reporting Initiative (GRI), a framework of the Carbon Disclosure Project, or other
guidelines. Nonfinancial information, which plays an important role in accounting
information system, has the potential to add significant value (Fraser, 2012), the
nonfinancial information disclosure makes companies develop more sustainably,
enable the value of enterprises to be recognized by the society and enhance the
competitiveness of companies worldwide.
In Vietnam, companies mostly pay attention to financial information, and some
types of nonfinancial information which present in the notes of financial statements
are used to explain and support for financial information, not the nonfinancial
information about the environment, society, etc. However, some companies listed on
the stock exchange are aware of the important role of nonfinancial information
disclosure according to international standards like the G4 guideline of Global
Initiative Organization (GRI4) such as Vinamilk joint stock company, Hau Giang
pharmaceutical joint stock company, Imexpharm pharmaceutical joint stock

company… As a results, these companies are greatly trusted by both national and

international investors and their value is internationally recognized.
Vietnam has been a member of many organizations worldwide like WTO,
AFTA, AEC…, so there is a greater need for economic integration to attract foreign
investors. Moreover, when sustainable development are becoming more and more
competitive, Vietnamese accounting reports also need to disclose mandatory
nonfinancial information, especially social and environmental information, etc.
Therefore, in the year 2015, the Ministry of Finance issued Circular No.
155/2015/TT-BTC regarding information disclosure on securities market. The circular
155 requires listed companies to report on their impacts on the environment and
society. After a year of the implementation, companies which disclose nonfinancial
information according to the G4 guideline apply easily the circular 155/BTC. While
the others apply the circular 115/BTC inadequately and eliminate some indexes due to
the lack of information about gathering, processing and disclosing.
As a result, research on nonfinancial information disclosure are gaining more
attention. Around the world, there are several research on the level of nonfinancial
information disclosure and factors affecting this level, like Mobus (2005), Levine and
Smith (2011), Babaloo (2012), Skouloudis and et al (2013), Behbahani and et ah
(2013a, 2013b), Karim and et al (2013), Ioannou và Sarefeim (2014), Khan and et al
(2014), Ghasempour Grewal and et al (2015), Christensen and et al (2015), Kaya
(2016), Mihajlov and Spasic (2016), Rezaee và Tuo (2017), Manes-Rossi and et al
(2018), Gulin and et al (2018), Sierra-Garcia and et al (2018), Szadziewska and et al
(2018)… Nonetheless, in Vietnam, the kind of the research topic only has some
studies such as the research of Ta Quang Binh (2012, 2014), Pham Duc Hieu and Do
Thi Huong Lan (2015). Therefore, it is necessary to choose the topic “Measuring the
level of nonfinancial information disclosure and factors affecting the level of
nonfinancial information of companies listed on the stock exchange in Vietnam” as
the research topic for the dissertation.

CHAPTER 1
LITERATURE REVIEW
1.1

Researches on the mandatory disclosure of non-financial information
The characteristics of this research line are the measurement of the level of
mandatory non-financial information disclosure. The researchers used the unweighted
index method to measure the level of mandatory non-financial information disclosure.
The disclosure indices of a company were prepared base on the national regulations
system. In this research line, authors used statistical methods to describe the results of
the forced publication of non-financial information relative to regulations, thereby
assessing the compliance level of non-financial information disclosures of companies
in the research sample.
1.1.1 Researches on the mandatory disclosure of non-financial information in
the world
With the research direction of mandatory disclosure of non-financial
information, there have been a lot of researches, such as Mobus (2005), Levine and
Smith (2011), BaBaLoo (2012), Ioannou and Serafeim (2014), Grewal et al. (2015),
Christensen et al. (2015) and Kaya (2016), Manes-Rossi and et al (2018), Gulin and et
al (2018), Sierra-Garcia and et al (2018), Szadziewska and et al (2018).
1.1.2 Researches on the mandatory disclosure of non-financial information in
Vietnam
In Vietnam, the author has not found a separate study on mandatory disclosure of nonfinancial information yet.

1.2 Researches on the voluntary disclosure of non-financial information
The characteristics of this research line are non-financial information that has been
studied extensively. The researchers used the unweighted or weighted index method to
measure the level of voluntary disclosure of non-financial information. Some
researchers used the content analysis method. After that, they used the descriptive
statistical method to measure the level of voluntary disclosure. Each author divided
the degree of disclosure by intervals, without template, to evaluate the level of nonfinancial information disclosure of the companies in the research sample.
1.2.1 Researches on the voluntary disclosure of non-financial information in the
world
With the second research line of voluntary disclosure of non-financial information,
there are some authors such as Karim et al. (2013), Khan et al. (2014), Ghasempour
and Yusof (2014), Mihajlov and Spasic (2016), Rezaee and Tuo (2017).
1.2.2 Researches on voluntary disclosure of non-financial information in
Vietnam
In Vietnam, the second line of voluntary disclosure of non-financial
information is relatively modest, with some authors such as Ta Quang Binh (2012), Ta
Quang Binh (2014), Pham Duc Hieu and Do Thi Huong Lan (2015).
1.3 Researches related to factors affecting the level of non-financial
information disclosure
With the third research line on factors affecting non-financial information,
regardless of mandatory or voluntary disclosure, conducted by Meek et al. (1995),
Robb et al. (2001), Skouloudis et al. (2013), Karim et al. (2013), Arif and Tuhin

1.4 Evaluation of previous studies and Determination of the research gap
1.4.1 Evaluation of previous studies
In the world, this is a full-fledged research series, conducted by three research
lines (1) research on the compulsory disclosure level of non-financial information, (2)
research on the voluntary disclosure level of non-financial information, and (3)
research on factors affecting the level disclosure of non-financial information. In
Vietnam, the first research line (1) the mandatory disclosure level of non-financial
information has not been studyed, the second research line (2) the voluntary disclosure
level of non-financial information has been studyed rarely and inadequately. And the
third research line (3) factors affecting the level disclosure of non-financial
information has studyed limitedly and inadequately. Most of the previous studies used
the non-weighted index method to mark non-financial information disclosure and used
statistical methods to measure the level disclosure of non-financial information. In
addition, the studies used a regression method to test the effect of factors on the level
disclosure of non-financial information.
1.4.2 Determination of the research gap
From the above analysis, the author will detect the research gap for author’s
research on non-financial information disclosure as follows:
+ To measure the level of non-financial disclosure of companies listed on the
Vietnamese stock exchange in accordance with Vietnamese regulations, and according
to GRI4 regulations of the world. From that, to evaluate and compare the level of nonfinancial information disclosure of listed companies in accordance to Vietnam

regulation with the world standard.
+ To identify the factors from literature review and to explore new factors that
impact on the level of non-financial information disclosure, and measure the
impactation of each factor on the level of nonfinancial information disclosure of
companies listed in Vietnam.

CHAPTER 2
LITERATURE REVIEW
2.1 Overview of Non-financial information
2.1.1 Denifition of non-financial information
Non-financial information is a broad concept that is reflected in the various
definitions of researchers or professional institutions, such as Meek et al.
(1995), Robb et al. (2001), Dominique (2009), Eccles and Krzus (2010), Fraser
(2012), INTOSAI (2013) , European Commission (2013), Forser (2012 ), ICAEW
(2008), Admiraal, Nivra, and Turksema Skouloudis et al. (2013), Financial Times
Lexicon (2015), E&Y (2015). As such, non-financial information is a broad concept,
which may be qualitative or quantitative data, not measured in monetary terms,
depending on the type of report that non-financial information is presented differently.
Therefore, in the dissertation, non-financial information is presented in the annual
reports that includes the general non-financial information about the company,
environment, social, corporate governance, and other non-financial information.
2.1.2 The role of non-financial information
2.1.3 Users of non-financial information
2.1.4 Forms of non-financial disclosure
According to the Association of Chartered Accountants of England and Wales
(ICAEW), non-financial information presented in each report is different, as follows:

2.2 Guidelines of non-financial information disclosure
2.2.1 Guidelines for non-financial disclosure in the world
2.2.1.1 Under guidelines G4 of the Global Reporting Initiative (GRI4)
2.2.1.2 Under Singapore framework
2.2.2 Guidelines for non-financial disclosure in Vietnam
2.2.2.1 Under the Vietnames Accounting Standards
2.2.2.2 Under guidelines for disclosure on securities market
2.3 Non-financial Information Disclosure Measurement Method
Hassan and Marston (2010) studied the disclosure measurement methods. The
authors examined 40 previous studies on measuring disclosure. The results of the
study show that: (1) The study presented measures of disclosure provided in prior
studies classified into two approaches. The first approach includes proxies for
disclosure, which are not directly based on examining the original disclosure
vehicle(s). The second approach provides measures of disclosure obtained by
inspecting the original disclosure vehicle(s). (2) Frequency of methods used to
measure quantity / quality of information disclosure.
The results of Hassan and Marston (2010) show that some studies can use
two or more proxies for disclosure. Statistical results suggest that the most used
method in disclosure measurement was the disclosure index with rate 32%.

RESEARCH METHODS, FINDINGS AND DISCUSSION ON MEASURING
THE LEVEL OF NON-FINANCIAL INFORMATION DISCLOSURE
3.1. Research design
3.1.1. Appropriate research methodology
3.1.2. Research process
3.1.3 Scoring Methodology of nonfinancial information disclosure
The author has chosen the unweighted index method in order to identify the
disclosure level of nonfinancial information such as prior researches of Behbahani
(2013a, 2013b), Ghasempour and Yusof (2014), Ta Quang Binh (2014), Pham Duc Hieu
and Do Thi Huong Lan (2015), Grewal et al. (2015), Kaya (2016), ... The method
analyses each category using a “1, 0” scoring methodology. If there is information of
subcategories, these subcategories will gain a score of 1, whereas a score of 0 will be
awared if no information subcategory is disclosed. Therefore, the non-financial
information disclosure (NFID) index is calculated according to the following formula:
∑𝑛𝑖=1 𝑑𝑖𝑗
NFIDj
=
𝑛
Where:
+ NFIDj: Total of non-financial informationa disclosure of company j in according
to Vietnamese regulations, and GRI4 regulations.
+ dij = 1 if subcategory is disclosed
+ dij = 0 if no information subcategory is disclosed
+ n: The number of non-financial information items are disclosed.
3.1.4 Research Conduction
3.1.4.1 Research Sample:

The study covers 577 non-financial companies listed on HOSE and HNX. The
sample period in this study is only for the year ending on December 31, 2016
3.1.4.2 Data Collection and Processing
3.2 Findings and discussion
3.2.1 Findings
3.2.1.1 Measuring the level of non-financial disclosure according to Vietnamese
regulations
From the descriptive statistics result, the mean value of non-financial information
disclosure index is 35.67 items (total 61 items), approximately 58.5%, it belongs to the
average level. whereas the lowest value of non-financial information disclosure index is
18%, below the average. The highest value is 86.9%, reaching a high level.
3.2.1.2 Measuring the non-financial disclosure level in accordance with GRI4
From the descriptive statistics result, the mean value of non-financial information
disclosure index in accordance with GRI4 is 56.51 items (total 193 items), approximately


12

29.3%, it belongs to below the average level (< 50%). whereas the lowest value of nonfinancial information disclosure index is 7.8%, which is low. The highest value is 72.5%.
3.2.2 Discussion
3.2.2.1 Discussing the level of non-financial disclosure according to Vietnamese
regulations
Survey results show that general non-financial information is considered necessary
information, so that listed companies in the research sample disclosed adequatly 18/18
items, reaching 100%. However, there are also few companies got the disclosure level
very low. the lowest is 6/18 items, reaching 33.3%, example of Khang An Real Estate
Joint Stock Company (KAC). KAC did not disclose the nonfinancial information such as
company introduction, the process of formation and development, business area,
governance structure, management structure, executive board list... Regarding
environmental information, the compliance level

of environmental information
disclosure is high with 8/8 items, reaching 100%, but there are also non-compliant
companies, environmental information is 0/8 items. In fact, the survey results show that
environmental information disclosure of listed companies is still very sketchy and
coping. Many companies just listed titles of items without detail disclosure such as Cu
Chi Commercial and Industrial Developing Investment JSC (CCT), De Tam Joint Stock
Company (DTA), Development Investment Construction Number 2 JSC (DC2),
Educational Book JSC In Hanoi City (EBS), Education Cartography And Illustration JSC
(ECI), etc ... or there are cases where companies disclose nonfinancial information in an
integrated report but the information items are not comply with regulation of circular
155/BTC and only declare compliance with environmental regulations such as Hydro
Power Joint Stock Company – Power No.3 (DRL), Do Thanh Technology Corporation
(DTT), FECON Corporation (FCN), International Gas Product Shipping Joint Stock
Company (GSP), Nagakawa Group Joint Stock Company (NAG), Vinacomin - Nui Beo
Coal JSC (NBC),…With seven social information items under Circular 155/BTC,
companies has not reached the maximum level (7/7 items), only 20 listed companies
disclose 6/7 items, approximately 4.14% research sample.
3.2.2.2 Discussing the non-financial disclosure level in accordance with GRI4.
Non-financial disclosures under the guidance G4 of Global Reporting Initiative are
not mandatory in Vietnam, and listed companies may voluntarily disclose non-financial
information such as environmental, social and corporate governance in accordance with
this guideline.
According to the survey results, the level of non-financial information disclosure
of GRI4 was low at 29.3%, reaching below the average level (<50%). The gap between
listed company with the lowest GRI4 (15 points) and the highest (140 points) is quite far,
the difference is 125 points.
The survey results are the same the report of the council of Vietnam listed
company awards1 in 2017: "There is a gap in the sustainability report of high-ranking
businesses and the remaining businesses which show an uneven understanding between
businesses on GRI's G4 guidelines and many missing reports basic parts of a GRI

report".
Companies listed in the sample with non-financial information disclosure points
according to G4 guidelines have a high score as those companies that publish

CONCLUSIONS AND RECOMMENDATION
5.1. Conclusions
5.1.1 Nonfinancial information disclosure level of listed companies in Vietnam
5.1.2 Factors affect nonfinancial information disclosure level of listed companies in
Vietnam
5.2 Recommendation
5.2.1 Regarding the level of nonfinancial information disclosure
5.2.1.1 The level of non-financial information disclosure in accordance with
Vietnamese regulations
Based on the above analysis, the author suggests some policy and management
emphasize the nonfinancial information disclosure level as follows:
Strengthen company training: Government offices such as The Ministry Of
Finance Of The Socialist Republic Of Vietnam, the State Securities Commission Of
Vietnam, Vietnam Association of Accountants and Auditors (VAA) and Vietnam
Association of Certified Public Accountants (VACPA) need to organize the training
courses which support, guide companies to practice sustainable development report or
integrated with annual report by regulations.
Review the Appendix 4 – Circular 155/BTC: Listed companies who have had
knowledge about the regulations of information disclosure really unequal or understand in
the different ways about the meaning of Appendix 04 of Circular 155/BTC, so, the
Ministry of Finance of the Socialist Republic of Vietnam must establish a clear direction
about non-financial information part which relates to environment, society to aim the

listed companies to avoid misunderstanding about these regulations (see Appendix 19)
The listed companies need to build the process which is gathering, processing and
disclose the non- financial information: this purpose ensures the information disclosure is
reliable and timeliness and meet the compulsory non-financial information regulation of
these listed companies.
Sanctioning listed companies do not comply with non-financial information
disclosure regulations: like auditing financial statements, auditing companies need to
assess and give an opinion listed companies' non- financial information disclosure, then
the State Securities Commission of Vietnam have the evidence to sanction for listed
companies that disclose unadequately in accordance with regulations.
5.2.1.1 The level of non-financial information disclosure in accordance with GRI4
The reports on environment, society and corporate governance under the GRI’s G4
guidelines which is unconstraint to establish this condition on the financial reports,
because the listed companies in Vietnam establish this standard base on the company
spontaneous requirement, so there are not much the listed companies comply with this
GRI4, basing on the author research, actually the listed companies are still not clear the
benefit of the sustainable development report. These listed companies, must to actively
explore and apply to set up sustainability reporting under the GR’s G4 guideline combine


22

with the annual reports under circular 155/BTC. Beside this, the listed companies need to
understand about an important role of the non-financial information disclosure such as
environment, society and entity management. Beside the revenue, profit or loss, share
market, the companies or individual investor come from foreign investment funds also
focus on the non-financial information company factors which relate to environment,
society and company governance to decide whether making investment or not. Therefore,
the listed companies need to emphasize their responsibility which connect to
environment, society, public for company value growth, create good company image,

transparent manner of information of the companies in marketing, creating the trust from
investors to these companies.
In addition, the government management agencies such as state securities
commission of Vietnam, Vietnam Association of certified public accountant must to
propagate the standard for benefit, non-financial information’s benefit become more
necessary in the accounting information system. It has potential development which affect
to the company value (Fraser, 2012). The sustainable development report establishment
under GRI’s G4 includes: (1) Internal value in development of strategy vision of
organization, management, understand clearly about the internal department’s function,
easy to discover strong and weakness point, improve employee capacity…(2) Outside
part, basing on the transparent manner financial statements increase the trusted level of
investors, become more attractive to outside investment, cooperative improvement and
competition and other benefit collections. Beside this, the information disclosure under
this standard, the listed company can publish more information which relates to
environment, society and company management
5.2.2 Factors affect the level of non-financial information disclosure of listed
company in Vietnam
5.2.2.1 Company characteristic factors
Company Size factor
The results of regression analysis show that the company size factor create a
positive effect to the whole non-financial information disclosure in accordance with
Vietnamese regulation, and this factor has a strong impact to the information disclose
level which relates to the listed Vietnamese company spontaneity under GRI4
The big size of listed companies comply with the non-financial information
disclosure, and spontaneous trend to provide much more the non-financial information
under G4 guideline in comparison with the smaller size of listed companies are afraid to
disclose non-financial information or incapable resources to apply this standard into the
non-financial information disclosure under GRI.
Management policy aspect, government need to have the policy which expresses
control the non-financial information disclosure of the small size listed companies which

still get problems about costing and processing to collect eh data for information
disclosure under circular 155/BTC. With the large size of listed companies, government
must to have encourage policy to support these companies disclose non-financial
information under the international standards GRI4, as well as collect the typical listed
companies with large size for the standard compliance about non-financial information
disclosure under GRI4.
Beside this, the Vietnam professional association need to focus on training courses
and training the small size listed companies about the non-financial information
disclosure associated with the financial information, help the small size companies save
the cost for information disclosure and integration in information disclosure quickly.


23

Profitability factor
Regression analysis results express that profit through the return on assets ratio expresses
the positive impact to the non-financial information disclosure level under GRI4, the
listed companies has high profit as well as the high application under GRI4. So, the
author suggests the policy to the government management offices need to encourage the
listed companies that have profit or good business activities should comply with nonfinancial information disclosure under the international standard.
Company age factor
The result of regression analysis shows the age factor also affect in positive way to the
whole non-financial information disclosure under the regulation and GRI4. So, the
company have a length of time or extended life as long as well for regulation compliance
better than other companies and the level of company spontaneity applying the nonfinancial information disclosure under GRI4 much more.
For government policy, the controlling and training for each listed companies is quite
necessary especially for the new companies are just established and encourage listed
companies that established for long time ago must to apply the non-financial information
disclosure according to the GRI4.
The new listed companies are just established are lacking off the information disclosure

processing, so, they need to build the process for collecting, processing and disclosing the
data which relate to the non-financial information disclosure according to regulation.
Period of listing time factor
The factor of listing time has a negative effect to the non-financial information disclosure
according to GRI4. Thus, the companies have the longer listing time the more decrease
level of non-financial information disclose. To the government management offices need
monitor closely to non-financial information disclosure of these long listing time
companies as well as improve the policy for propaganda for these companies about the
role and profit of non-financial information disclosure under the GRI4 standard, this is the
advantage competition between these listed companies to compete or take the priority
from foreign investment funds
Foreign liabilities
Foreign loan factor expresses positive effect to the spontaneous level of the nonfinancial information disclosure under the GRI4. So, the author recommends policy to
listed company who have foreign partner or investors need to have an attention about the
information disclosure as well as the financial information such as profit, operation
business activities, … foreign partners also concern the non-financial information
disclosure of company to evaluate the social responsibility of companies in business
activities.
5.2.2.2 Ownership Structure factor
State ownership factor
Regression analysis’s result shows the state ownership factors have a positive
impact to the non-financial information disclosure level according with Vietnamese
regulation and GRI4 standard. So, the listed companies belong to the state ownership
have a strong compliance and spontaneous about non-financial information disclosure are
higher than others. Therefore, the non-financial information disclosure of the listed
companies must be kept an eyes by government agencies with the listed companies with
capital structure from government with minority percentage or without government
investment such as stakeholder.
Institution ownership factor

24

The result of regression analysis shows institution ownership factor also affect in
positive way to disclosure level of non-financial information under Vietnamese
regulation. So, the capital structure from one organization express the high rate of nonfinancial information disclosure’s regulation compliance than the organization owned by
many stakeholders. Therefore, the non-financial information disclosure must be much
more attention in to the companies with capital structure form many stakeholders.
5.2.2.3 Corporate Governance factors
Chief executive officer’s characteristic factor
The regression analysis’s result expresses chief executive officer’s competence
factor (CEO) have a positive influence to the non-financial information disclosure level,
so, the author suggest that the listed companies need to pay attention into the CEO’s
competence in promotion or appointment.
Auditing company factor
The auditing company factor also has a positive impact on the whole non-financial
information disclosure according to with GRI4. So, the listed companies which are
audited by Big 4 show the high spontaneous rate about non-financial information
disclosure.
From the research, the author gives some recommendations to the government
management agencies about improvement of quality control of the independent auditing
companies much more by methods: improve periodic inspections or inspections without
announce about the independent auditing companies’ activities, and issue the punishment
in law to prevent the independent auditing companies do not comply with the law to
affect the auditing service quality control.
5.3 Limitation and recommendation for future research direction
The dissertation applies the unweighted index method to mark non-financial
information disclosure level according to Vietnamese regulationa, and GRI4, but this
method also expresses some limitations such as:
(1) With the information lists are marked 1: the dissertation cannot distinguish the

listed companies disclose level in high rate, low rate or cannot measure the rate of
information disclosure exactly, because the companies just have information disclose
which is marked 1.
(2) With the information lists are marked 0: the listed companies do not disclose
information which is marked 0 and do not distinguish the companies have the information
disclose or not.
Form the above limitation, the dissertation gives some new opened direction for
the future research direction: To prevent the limitation of the index method for
information disclosure, the future research needs to apply the content analysis method.
With the content method, the listed companies have the information disclosure need to
counting words, sentences in each information disclosure items, so that, the limitations
are fixed when the company disclose information which has different disclosure level or
detailed information disclosure with the index method.


25

THE CONCLUSION
With the purpose of measurement assesses the non-financial information
disclosure level of the listed Vietnamese companies which comply accordance with
Vietnamese regulation and GRI4, and the target to determine the factor and measure
each factor’s influence which affects the non-financial information disclosure level,
the dissertation sets up the system which includes the previous international and
internal research results are arranged in a logical way, and base on the research
literature to mark the non-financial information disclosure score and give explanation
about the factors affecting to the non-financial information disclosure level, using the
mixture analysis method for study or research. The result of qualitative research
discovers the factors which are added into the empirical model, and the quantitative
research’s result, typically descriptive Statistic analysis to describe the research
objects, using the regression analysis to examine the research hypotheses.

The dissertation contains the theoretical meaning: testing and supplementing
the research method which measures the level of non-financial information disclosure
generally and a developing country such as Vietnam especially, testing and
supplementing factors into the empirical model and measure the factors impact the
non-financial information disclosure generally and there are specifically the influences
in the developing market such as Vietnam. In practical circumstance: the dissertation
expresses the measurement about the non-financial information level of the
Vietnamese listed companies in 2016 according to the Vietnamese regulation and the
G4 guidance which belongs the global reporting initiative (known as GRI -an
international independent standards organization). This shows the non-financial
information disclosure level of these listed company in which rate is matching or not
with the international standards, and distribute the policy implication for the
government management agencies and company management from the dissertation’s
result. About the company aspect, the dissertation suggests the management policy
which connects to each factor influences to the nonfinancial information disclosure,
then these become the benefit in non-financial information disclosure of listed
companies in the better way and the information become more detail and faithfully
represented financial information. About the government management offices, they
need to review some regulation documents, policies about the non-financial
information disclosure, Circular 155/BTC in particular need have some adjustments to
matching the reality closely. About the Vietnamese research associations such as
Vietnam Association of Certified Public Accountant (VACPA), the dissertation is an
elaborate, serious research document which is quite necessary for the professional
researchers especially in accounting field with the purpose to compare the other
resource documents for teaching about non-financial information disclosure level, and
the factors which affect to the non-financial information disclosure.
However, the dissertation also offers some limitations on the method in
measurement and still not discover some other factors affecting non-financial
information disclosure, so the dissertation just becomes the foundation for other future
researcher reaching the new results or new research aspects.
