Abstract
This paper analyzes the impacts of all FTAs in the ASEAN+3 region which
Vietnam has signed on Vietnam Iron and Steel trading status. In this respect, a gravity
model is used with panel data an dordinary least-squares (OLS) regression method
covering 27 top trading countries from 2001 to 2012. The final gains of the paper is to
point out clearly the positive impact of ACFTA and VJEPA on increasing import flows
of iron and steel into Vietnam while AKFTA, AFTA and VJEPA has played positive
effects on exporting. AJCEP and AFTA are concluded to have little impact on both
import and export volume. Besides, effects of other determinants apart from FTAs on
trading status are also gained after this paper.
Tóm tắt
Bài nghiên cứu đi sâu đánh giá tác động của các Hiệp định thương mại tự do
(FTA) mà Việt Nam đã ký kết trong khu vực ASEAN+3 đối với hoạt động xuất nhập khẩu
mặt hàng sắt thép của Việt Nam. Phương pháp mô hình trọng lực đã được sử dụng với
nguồn dữ liệu dạng bảng, ước lượng bình phương nhỏ nhất, chạy hồi quy trên mẫu dữ
liệu bao gồm lưu lượng xuất khẩu, nhập khẩu mặt hàng sắt thép với của Việt Nam với 27
quốc gia có cán cân thương mại xuất nhập khẩu lớn với Việt Nam về mặt hàng sắt thép
từ năm 2001 đến năm 2012. Bài nghiên cứu đã chỉ ra Hiệp định ASEAN- Trung Quốc
(ACFTA) và Hiệp định song phương Việt Nam- Nhật Bản (VJEPA) có tác động thuận với
hoạt động nhập khẩu các mặt hàng sắt thép của Việt Nam trong khi các hiệp định ASEAN
- Hàn Quốc (AKFTA), Hiệp định thương mại tự do (AFTA) có ảnh hưởng tích cực đến
hoạt động xuất khẩu mặt hàng sắt thép của Việt Nam. ẠJCEP và AFTA được ghi nhận là
những hiệp định chưa có nhiều tác động đến hoạt động ngoại thương của ngành sắt thép
Việt Nam. Mức độ ảnh hưởng của những nhân tố khác ngoài các hiệp định đối với hoạt
động xuất nhập khẩu sắt thép của Việt Nam cũng đã được chỉ ra trong bài nghiên cứu.
1. Introduction
1 The research could not be completed without kind support of Mr. Nguyen Thanh Tung, Mr. Pham Van Nho and
Mr. Nguyen Tri Si. We are truly grateful to say thank to all of them. Any remaining mistakes are by the authors
alone.

The establishment of FTAs has been regarded as a commitment between member
nations towards a free trade area. The impacts of increasing Regional trade agreements
over years have been figured out in several industries. Iron and steel industry is known as
a sensitive industry in Vietnam which also under the significant effects of free trade
agreements. In this paper, the author tries to address main concern about the impacts of
FTAs under ASEAN+3 on Vietnam Iron and Steel industry. How is the current status of
tariff reduction of Vietnam iron and steel industry under FTAs? Up to now, what is the
trading status of Vietnam Iron and Steel Industry in ASEAN+3? These questions are all
explored carefully.
In this study, Reveal Comparative Advantage Index (RCA) of Vietnam iron and
steel industry is calculated to show how competitive is iron and steel in Vietnam’s export
compared to the product’s exports in relations to its share in the world trade while Export
and import intensity index are cultivated to measure which nations Vietnam has larger
share in export and import iron and steel. More importantly, to have a clear answer about
the effect level of FTAs on trading flows of iron and steel products, a gravity model
approach is used. Basing upon the available of information, data used in the model are
from 2001 to 2012 from trusted sources.
The paper is divided into five major sections. First, a brief introduction about the
content of the paper is pointed out. Second part is a specific review of the methodology
of all previous researches. While in some ways, the paper is quite similar to the works of
URATA Shujiro and OKABE Misa (2007) in having depicted an image of trade flows
under the effects of FTAs, or Sohn, Chan-Hyun (2001) in using the gravity model
analysis to work out the relationship between the trading flows and regional trading
agreements, especially Nguyen Tien Dung (2011), this study still become unique in
applying gravity model in a new scope which is the iron and steel trade flows of Vietnam
under ASEAN+3.There has not been any study applying gravity model on Vietnam iron
and steel trade flows. Section 3 analyzes an integration of Vietnam Iron and Steel
Industry in ASEAN+3 in terms of the openness level of FTAs, competitive advantage of
Vietnam iron and steel industry in the regional integration and the change of trading
volume of Vietnam iron and steel industry after FTAs. Section 4 applies the gravity
model approach in clarifying whether FTAs has effects on iron and steel export and
imports. The final remaining part is followed to make a conclusion and
recommendations for Vietnam towards the integration in ASEAN+3.
2. Methodology
In this paper, the separate influences of FTAs and other variables are quantized by
percentage change of trading flows. The author uses gravity model to quantize the
impacts of Free trade Agreement on the import, export value of iron and steel industry
with supports of economic software eview 6.0 in order to examine the impact of the
FTAs on trade flows by controlling the factors other than tariff reduction.
Over the world, there have been a number of researches focusing on the analysis
of the effects of FTAs especially ones using gravity model to clarify the impacts of FTAs
within region on significant sectors of a country. The first formulations of the gravity
model equation are found in Timbergen (1962), Pöyhönen (1963). They applied to the
gravity equation to analyze international trade flows. Since then, the gravity model has
become popular instrument in empirical foreign trade flows. Initially, the gravity model
3
is used for explaining the exports from country i to country j which depends on the
economic sizes (GDP or GNP), their populations, direct geographical distance and a set
of dummies incorporating some kind of institutional characteristics common to specific
flows.
In the second half of the 1970s several theoretical developments have emerged in
support specifically the gravity model. Anderson (1979) made the formal attempt to
derive the gravity equation by adding assumption of product differentiation. In 1995,
Deadorff also proved that the gravity equation could be justified from standard trade
theories.
Up to now, the trend using the gravity model analysis to evaluate the effects of
FTAs on trade flows has been increasing sharply. The standard gravity model use
variables as followed: Real GDP, income gap (to account for intra-industry trade and
level of income), a measure of remoteness, adjacency and geographical characteristics
such as being landlocked. The original gravity equation looks as follows:
=
In which: A, a, b, c are the parameters to be estimated. The equation’s logarithmic
transformation is given by:
Log = + a.Log + b.Log + c.Log
The gravity model has been widely applied in international trade studies. Its
popularity is due to the concept simplicity, its appropriateness to match well with the
available data and the models’ econometric estimation. Depend upon the significant
purposes of the studies, the gravity model analysis is added more variables in many
researches to apply effectively the examination of the relationship among several factors
in international trade cases.
Determining suitable variables is one of the primary and most important
requirements in setting up econometric models to attain precise economic results. This
section provides analysis and explanations for variables used in the models.
The starting point of building up the models is based on the following
specification of the gravity model:
In which:
represents trade flows (exports or imports) between country 1 and country “i”
is the GDP of country “i”
represents the Distance between country 1 and country “i”
4
is Dummy variable indicating to which Regional and Preferential Trade
Agreement a particular country belongs: “i” runs from 1 to 5, reflecting respectively
AFTA, ASEAN-China, ASEAN-Korea, ASEAN-Japan, Japan-Vietnam Economic
Partnership Agreement. represents 1 -Membership in the specific FTAs, representing
0-otherwise.
In the simple form, the gravity equation can be re-written by logarithmic
transformation as bellows:
LOG( ) = C + LOG( ) + LOG( ) + LOG( )+
In which:
Σ (Sij) represents other variables that affect trade like history, language, land
locked, borders for example. Σ (Sij) represents 1 for Colonial ties, Common language,
Landlocked, Common borders; and Σ (Sij) equals 0 for otherwise.
It is depend upon the paper’s purpose which is to build up the appropriate model
to clarify out the answer for the research questions, the relationship between trade flows
and various explanatory variables will be estimated by ordinary least-squares (OLS)
regression methods.
For this paper, in order to evaluate the impacts of FTAs in ASEAN+3 region
which Vietnam has signed until now, including AFTA, ACFTA, AKFTA, AJCEP,
VJEPA on the Vietnam iron and steel industry, the author has made decision of using the
gravity model to cultivate how much these FTA affect the Vietnam iron and steel
industry’s trading. This model will be hoped to analyze the trade flows of Vietnam Iron
and Steel products with other nations on the account of the several factors, such as Real
GDP, Real GDP per capita, Real exchange rate, Income Gap, Distance between
countries. The author do hope that this gravity model will indicates whether FTAs
affected the Vietnam iron and steel industry in the scope of research, FTAs increase or
decrease the trading flows of Vietnam iron and steel industry with ASEAN+3 nations
compared to the previous normal trades flows. To examine the impacts of FTAs, dummy
variables are added into the model. If these dummy variables have positive and
significant coefficients, this means that FTA will have a good effect of accelerating the
trade flows among countries.
The gravity model in this study will have general variables in the standard gravity
model and such a number of additional dummy variables of FTAs, Border and Land
locked. Lack of coastline increases the time and cost of transportation as well as the
dependence on the quality of the infrastructure network across the region as a whole,
particularly that of the neighboring countries. Besides, the author also finds that the
increase in total trade of iron and steel products of Vietnam comes from improvement in
infrastructure, followed by logistics and efficiency of customs and other border agencies.
The non-tariff barriers also are taken into consideration, as the main challenges of
exporting iron and steel of Vietnam into other countries in ASEAN seems to be the
nontariff barriers imposed by the home countries’ government, besides tariff. The FTAs
dummy were put into this equation are the FTAs membership. When adding FTAs
dummy, this paper mentions to the impacts of being membership of FTAs in general.
5
After all, there were many motives from the author to examine the effects of several
factors on Vietnam iron and steel trade flow, however, depending on the availability of
the data base, the author will build the exporting model and importing model as
bellowed:
(i) Log = + Log + Log + +
+ + +
(ii) Log = + Log + Log + +
+ + +
In here: and are the export volume and import volume of Vietnam Iron
and steel products to the country j, Gap is the differences of Real GDP per capita of
Vietnam and the country j; Distw is the geographical distance from Vietnam to country j
which is standardized for populations; are the dummy variables measuring the
impacts of FTAs membership on the export and import flows between Vietnam and the
countries.
Export and Import flows (Yi) measured in dollars; Real GDP and Gap measured in
dollars, Distance are in thousands of kilometers, Borders represents 1 if they share a
common border and 0 otherwise. The FTAs dummy represents 0 if the trading partner is
not the member of corresponding FTA and 1 if the trading partner is the member of that
FTA since the year FTA goes into effects. Consequently, the dummy variables AFTA,
ACFTA, AKFTA, AJCEP and VJEPA will be 1 since the following years, respectively,
2006, 2006, 2007 and 2010 for the AJCEP, VJEPA. Landlocked equals 1 if the trading
country j is landlocked, 0 otherwise. The author choose those years as from this years,
such a significant tariff elimination of FTAs has been practically undertaken on Vietnam
iron and steel products and have big effects on Iron and steel industry trades.
Besides, some other important index in international trade is also used in this
study. Firstly, the Reveal Comparative Advantage Index (RCA) of Vietnam iron and steel
industry is calculated to show how competitive is iron and steel in Vietnam’s export
compared to the product’s exports in relations to its share in the world trade. The
equation to calculate RCA is shown below:
Where and are the values of Vietnam’s exports of iron and steel products
and world exports of iron and steel; and represents Vietnam’s total exports and
world total exports.
Secondly, other indexes which are also cultivated are Export Intensity Index and
Import intensity Indices. These indices reflects the ratio of the share of country i’s trade
with country j relative to the share of the world trade destined for country j. They can be
defined as follows:
6
Where: : Country i’s exports to country j; : country i’s total exports to the
world : country j’s total imports from the world; : world total imports; :
country i’s total imports from the world; : country i’s exports to country j; :
country j’s total exports to the world; : world total exports.
3. Data
The model uses the export and import statistics from UN COMTRADE data base
from the year 2001 to 2012 as the availability of Vietnam’s data base in this period. Real
GDP are sourced from World Bank; the Gap is calculated from Real GDP per capita
taken from World Bank; Distw; Border and Landlocked are taken from CEPII. There are
total 27 top trading partners in iron and steel which are recorded in the model for the
period 2001-2012 from the data base of UNCOMTRADE2.
According to Economic theory, real GDP will correlate positively with trade
activities. Higher income levels will lead to higher demand on the trading of goods.
Therefore, the volume of exchange goods will be greater. Iron and steel are the typical
goods following that trend. Distances are supposed to have negative impact on both
exporting and importing. The farther the distance is, the higher transportation costs might
be. High transportation cost will hinder the exchanges of goods among nations. In other
words, the greater the distance is, the less trade between countries is. The Income Gap
variable is calculated as the differences between real GDP per capita of each countries
and it is used to check out whether the trade depends on intra-trade or inter-trade. It may
be positive or negative. When the coefficient of this variable is positive, this means trade
flows are mainly depend upon the inter-industry trade based on differences in factors of
production resources. In contrast, if the income gap has a negative sign, it shows impact
of intra-industry trade.
Data used in the model are from 2001 to 2012, and is collected from trusted
sources such as:
Real GDPs, real GDP per capita (taken fixed 2005 USD’s price), are taken from
in the World Bank’s World Development Indicators
Export and import flows is picked up from WIST
2Trading partners are used in this model: Australia, Belgium, Benin, Brunei, Cambodia, Canada,
Chile, China, Colombia, Haiti, Hong Kong, India, Indonesia, Taiwan, Japan, Korea, Lao,
Malaysia, Netherlands, New Zealand, Philippines, Russia Singapore, Thailand, United Kingdom
and United States. Myanmar is excluded as the lack of statistics.

From the table I, the outstanding outcome to be noted is the RCA of Vietnam in
Iron and steel industry appear to be the highest index compared to ASEAN nations in
each year from 2001 to 2012. The computation of RCA for iron and steel showed that
Vietnam has developed comparative advantage in the product category over the period of
time. The general trend of RCA through years was upward trend and on account of the
further integration of Vietnam into the international market, RCA of Vietnam has been
hoped to keep increasing in the near future.
Nevertheless, the RCA of Vietnam was below one. We aware that RCA were
regarded as low if it is below one and strong if it is over one or two. The case of Vietnam,
all of RCA index over years were still below 1, which reveals that Vietnam seemed not to
have comparative advantages in iron and steel products. This industry depends on the
availability of natural resources in country and the development of the industry. A
snapshot of Vietnam iron and steel industry in the integration phase can explain clearly
8
why Vietnam has comparative disadvantage in iron and steel industry, although the role
of this industry is typically important for the reform of country.
Besides, the RCA of ASEAN nations were below one, in other words, all of these
countries got comparative disadvantage with big trading partner China, Korea, Japan.
Therefore, most of the ASEAN countries including Vietnam, can facilitate importing iron
and steel from Japan, China and Korea in ASEAN+3 region.
Apart from measuring the competitive advantages of Vietnam iron and steel with
other nations, the trade intensities is the typical index for pointing out the share of
Vietnam iron and steel trade with another country. The value of index may range from 0
to 100. It reflects that country is importing more (or less) from country j than might be
expected from that country’s share in total world trade. In export side, if the value is 0 or
nearer to 0, it implies that export link between these countries is negligible and if the
value is nearer to 100 that indicates that the performance is relatively significant and if it
exceeds 100 it reveals that a country export more than expected with the other countries.
The trade intensity is usually divided into the export intensity and import intensity.

The table II demonstrates that Vietnam’s export intensity and import intensity
index are mostly greater than one with all ASEAN+3 nations in iron and steel industry,
implying a strong link between Vietnam and individual members with associated FTAs
in the region. Vietnam’s import intensity index (MII) was quite small with Japan for
many years before 2010 but has improved strongly after signing the VJEPA. Vietnam’s
export has forced with Singapore recently, while declined with several countries, namely
Indonesia, Thailand and Malaysia. Cambodia and Lao become outstanding with high
value of export intensity index (EII) and MII with Vietnam, this comes froma low total
volume in both total export and import of these two country which the volume with
Vietnam plays a majority of.
This section, through the statistical analysis of trade intensity and RCA, the
strength and nature of bilateral trading relationships between countries, is examined.
Some concluding remarks are achieved. Vietnam has comparative disadvantage in iron
and steel industry. Meanwhile, Korea, China and Japan, with high RCA index of more
than one are confirmed to have comparative advantage in iron and steel sectors. ASEAN
nations have lower RCA than these big countries. Vietnam, in near future might keep
importing more from China, Japan and Korea. The export and import intensity indices
have proved for this trend, especially after the years of FTAs establishment. A last thing
to note is a strong trading relation among countries in iron and steel industry.
The table III gives the results for the regression coefficients of all variables for
Exports and Imports model. Almost all the standard gravity variables have the expected
and statistically significant sign. Besides, R-squared value in export and import model are
respectively 0.657 and 0.554, quite high and be accepted for depicting the export and
import equation.

Before examining the effects of FTAs on trade flows of Vietnam iron and
steel industry, the author does wish to high light the general effects of other
concerning variables in the model to check out its impacts on trade flows of
Vietnam iron and steel.
11
Firstly, Real GDP which measures the economies of scale are seen to have
positive sign in both export and import equation. It reveals that the growth of economy of
Vietnam as well as the trading countries will foster the export and import flows in and
out Vietnam. In other words, Real GDP factor has positive effects on trading of iron and
steel industry. More specific, for exporting, the volume will increase respectively by an
average of 0.496 percent and 8.09 percent if real GDP of the destination market and
Vietnam rise by about 1 unit. Importing iron and steel is also under the same positive
effect of real GDP as in exporting but with different coefficients.
Secondly, about the income gap variable, this one appeared to be positive sign in
export model and negative sign in importing one but there are no statistical significance
in both two equations. It can be explained that the exporting iron and steel of Vietnam
mainly are related to inter-industry trade with trading partners; meanwhile, the importing
iron and steel of Vietnam are intra-trade. However, this effect does not play in the trade
flows of iron and steel. It does not have any significant effects on the exporting and
importing volume of Vietnam iron and steel industry.
Thirdly, distance is recorded at negative sign with both export and importing
value. This matches with the theory in gravity models. Other dummies, like border,
landlocked are relatively meet the author’s expectation. Border has positive and
significant sign in export but negative sign in import equation. This comes from the data
base that Vietnam seems to export more easily with neighboring countries while imports
did not follow that trend. The import of Vietnam might be unique for some several
reasons. Vietnam seems to import more with the markets in which can supply the cheap
price but still guarantee suitable quality. Having borders with Vietnam, there are only
Lao, Cambodia and China. Luckily, there is only China having comparative advantages
for Vietnam to import. Lao, Cambodia, with the same or even lower developed level in
iron and steel industry, are likely not the key market to import for Vietnam, even though
they have borders advantage. However, the exporting to these countries is potential.
Landlocked, as presented in the previous section, are hindrance for trading activities. In
the iron and steel equation, landlocked has negative sign in import equation and does not
have much effects on exporting.
The most important part gained from the above table is the FTA’s effects on
Vietnam iron and steel trade flows. Among all FTAs mentioned, only AKFTA and
AJEPA are recorded as having significantly positive sign for exports model. AKFTA is
noticed as a FTA has positive and significant impact on the export when the coefficient
of AKFTA dummy is quite high at 1.556 at a significance level of 5 percent. This is
appropriate with the fact that from 2010, the export volume of iron and steel to Korea has
sharply plunged after 2007 when AKFTA went into force. VJEPA remarks a larger
impact on exporting when its coefficient reaches a number of 1.614 at the significant
level of 15 percent. This is consistent with the expected sign from the analysis in
previous section.
AFTA has a coefficient of 0.986 with statistically significant level of 15 percent,
indicating that AFTA has relative impact on Vietnam export iron and steel within
ASEAN region. The complicated trend of Vietnam export flows within ASEAN, as
depicted in the chapter 3 might reflect that export flows of Vietnam iron and steel
products is largely conflicted over time and it is difficult to clarify out clearly the impact
12
of AFTA on this era in short time but after all, AFTA still is illustrated to force the
exports flows of Vietnam. ACFTA also does not have significant sign in export equation.
The author can understand why this result comes out. There is the fact that China is a big
country of supplying iron and steel globally, the demand for importing this kind of goods
are still quite low, besides, there was a downward trend of Vietnam’s export flows to
China recently, this causes a negative sign of ACFTA but no statistically significant.
In term of importing model, ACFTA become the key FTA having positive and
statistically significant coefficient. An increase of about 2.559 percent in import value
will be gained from the establishment of ACFTA. Meanwhile, VJFTA creates an average
increase of 2.366 percent of import volume. From the view of iron and steel sector, China
and Japan are two main potential suppliers for Vietnam in long time. This outcome has
therefore, totally reflected accurately the fact of import flows among these countries
thanks to tariff elimination under ACFTA and VJEPA.
However, the downward trend of import flows recently of Vietnam from ASEAN
markets causes AFTA be reflected to have statistically negative sign of 1.910 percent.
Along with AFTA, AJCEP was also recorded at the same sign like AFTA with minus
1.109 percent in affecting the importing Vietnam iron and steel. It uncovers that joining
these FTA does not bring out improvement in the exports from ASEAN countries to
Vietnam in iron and steel sector. Only AKFTA, with the short time of establishment, in
the model, does not have significance in importing equation. It is the complicatedly
fluctuation of importing flow from Korea to Vietnam over years accompanying with a
short time of establishment of AKFTA that the effects does not be taken into account.
Hope that for the latter studies, with longer time of series data, it can be pointed out
accurately the influences of AKFTA. This outcome plays as a reflection only.
5. Conclusion
This paper has been successful to demonstrate the different effects of FTAs on
Vietnam Iron and steel trade flows. Depend upon the RCA, export intensity and import
intensity index, Vietnam are considered to have comparative disadvantage in iron and
steel productivity. The imports of Vietnam are strong with China, Japan and Korea while
for ASEAN nations, the intensity levels are quite less. When FTAs are implemented,
several changes in trade flows of Vietnam iron and steel products are improved. The
import from China has increased sharply over the years after 2006. The export of
Vietnam to Korea rises rapidly after 2010. AFTA are seen to have little impacts on trade
flows of Vietnam when trends are complicated over years. By quantizing statistics
through export and import gravity models, the impacts level of AKFTA, AFTA and
VJEPA are foreseen to force the export iron and steel products of Vietnam to the related
member nations. ACFTA and AJCEP do not have any significant effects on stimulating
the exporting iron and steel. For importing, ACFTA is remarked to force the importing
from China to Vietnam these years. VJEPA is also the FTAs gaining significantly good
impacts on forcing the importing from Japan. AKFTA, AFTA and AJCEP have not
uncovered the clear impact on Vietnam’s imports iron and steel. Vietnam iron and steel
industry should take advantages effectively of some FTAs which have positive effects on
exporting, such as AKFTA and VJEPA.

Despite that the research has gained major achievements, there are still some
limitations in the research, which create premise for the later studies. First, the more
observations we have, the better the estimation quality is. In the paper, however, data for
variables in the research are just collected from 2001 to 2012 due to time and budget
constraints. The paper bypasses some typical variables of the gravity model, only
concentrates on FTA membership and additional simple geographical variables like
Distance, Borders, Land locked when examining the influences of them on trade flows.
Thus, to some extent, it does not fully reflect the effects of all factors on Vietnam iron
and steel industry. The author hope that in the latter studies, some other variables like
FDI could be added into the equation to check it out the impact level of this typical
variable on trading flows. Besides, the models in the research have a backward looking
characteristic. It means they are set up to make statements for the previous and present
status of Vietnam iron and steel trade flows. The suggestion for the next period of the
development of Vietnam iron and steel industry is not cultivated.
