ABSTRACT
This research examines and analyses the impact
ofFDI
on labor productivity at firm level
in
Vietnam through applying cross-sectional data from VES-2008 which concentrate on
4,654
firms including FDI and domestically owned enterprises in 4 sub-industrial sectors;
food processing, hotels - restaurants, electronics - mechanics and textile - garment -
footwear. The regression model
is
estimated based on the Cobb-Douglas production
function and the labor productivity
is
modeled as dependent on the variables, namely
capital intensity, material input cost per labor, proportion
of
skilled labor and dummy
variables including types
of
skilled labor that does not appear to
affect on labor productivity in this research.

CHAPTER I
INTRODUCTION
1.1. Problem Statement
Since the late 1980s, on the basis
of
Doi Moi or the government's socio-economic
reforms which started in 1986, Vietnam has initially transited from a centrally planned to
a market- oriented economy. Typically
for
this process, Vietnam has advocated economic
integration, in addition to its
five
"tions": urbanization, globalization, industrialization,
modernization and privatization to spearhead this process. Beginning with the
is
an indispensable capital source
to
developing
countries including Vietnam, especially Asia's Newly Industrializing Countries (NICs).
Through FDI flows, these countries can cover the saving-investment, foreign exchange
and fiscal gaps and hence promote socio-economic growth, Taylor (1993).
It
may seem natural to argue that FDI can convey great advantages to host countries.
That
is
why policymakers
of
developing countries including Vietnam always pay much
attention to effects from FDI flows to country's economic growth. However this study
does not focus on FDI
by
examining the effects
of
foreign direct investment on
Vietnam's socio-economic growth in a general respect, this research wants
to
test the
impact
of
FDI on the labor productivity at firm level in Vietnam as a whole and to
1
identify main significant determinants
of
the FDI impacts to examine whether they vary
1.2. Research objectives
The general objective
of
the research will investigate whether FDI increases the overall
labor productivity
in
Vietnam, as measured
by
term
of
value added per labor, focusing
on
enterprises
of
four sub-industries; food processing, hotels and restaurants, textile,
garment and footwear and electronics and mechanics including domestic and FDI firms
located over the country.
To meet this overall objective, the research will also target two specific objectives,
to
evaluate whether:
(i)
The impact
of
FDI has enhanced on labor productivity in Vietnam more than
domestically-owned firms including state owned firms and non-state owned
firms?
(ii) Make recommendations to policy-makers in Vietnam
as
to how to best channel
FDI
expected
to
confirm the sign
and statistical significance
of
following results:
1)
The determinants on the labor productivity in Vietnam has significantly positive
relation and depend on the terms
of
industry's capital intensity, proportion
of
labor skills and frrm's scale
of
material input purchases.
2)
The impact
of
FDI on the labor productivity significantly enhances
on
labor
productivity in Vietnam but differs significantly across regions and among four
sub-industries in the research.
3)
The determinants on the labor productivity m Vietnam vanes based on the
ownership structure
of
firms and amongst, FDI firms make the most productive
in
increasing labor productivity compared with
discussed mainly in chapter 3 which introduces a general view about FDI
characteristics, roles and inflows in national economy, FDI enterprises' activity as well
as
socio-economic effectiveness
of
these enterprises
in
Vietnam. Following, chapter

Research methodology concentrates on model specification and the justification
of
variable selection
as
well as dig deeply econometric problems. The practical results
of

of
FDI impact on labor productivity at firm level
is
generally figured out on the basis
of
economic theories and empirical studies.
2.2. Concepts and definitions
2.2.1. Foreign Direct Investment (FDI):
There are several ways to define FDI such
as
International Monetary Fund's FDI
definition or United Nations' FDI defmition. However one
of
the clear and popular
definitions comes from
Organization
for
Economic Co-operation and Development
(OECD). According to OECD (1996),
FDI
is
defined
as
follows:
"Foreign direct investment reflects
the
objective
of
obtaining a lasting interest by a
resident entity
subsequent capital transactions between them
and
among affiliated enterprises, both
incorporated and
unincorporated."
The OECD (1996) also recommends in its Benchmark definition that for the existence
of
a direct investment relationship the "full consolidated system" should
be
followed. In
other words, it means that when there
is
a cascade
of
participations, the percentage
of
the
parent company in any affiliated companies should be calculated assuming the
100%
of
the subsidiaries and the corresponding percentage
of
the associates. However, this
criterion does not correspond with the consolidation concept in the accounting statement.
Besides
OECD's FDI definition, Vietnam's GSO (2007) also explained Foreign Direct
Investment
as the bringing
of
capital into Vietnam
a useful measure because
it relates to the most important factor
of
production labor and
it
is
relatively easy to
measure, Ngoc (2008). In addition, Circular No. 06/2001/TT-BLDTBXH states that the
labor productivity to
be
determined by enterprises must
be
equal to the number
of
wage
unit prices they formulate for expertise in January 29,
2001
in guiding the calculation
of
the average labor productivity growth rate and the average wage increase rate in State
owned enterprises.
Although labor productivity can
be
measured
in
physical terms or
in
price terms
for
a
the public sector or
in
NGOs. Therefore, measured labor productivity can depend on many ways; the purpose
of
measurement or the availability
of
data about factors affecting performance.
In a survey
of
manufacturing growth and performance in Britain and other countries
of
IRS (2003), it was found that the factors affecting labor productivity or the performance
of
individual work roles are ofbroadly the same type
as
those that affect the performance
of
manufacturing firms
as
a whole. They include: (1) physical-organic, location, and
technological factors; (2) cultural belief-value and individual attitudinal, motivational and
behavioral factors; (3) international influences - for instance, levels
of
innovativeness
and efficiency on the part
of
the owners and managers
of
inward FDI companies; (4)
managerial-organizational and wider economic and political-legal environments; (5)
as
the public became more concerned with the importance
of
natural
resources (for example, the need to restore land to its original condition after strip mining
for
coal as well as cleaner air and water).
In this thesis, value added per labor
is
the term which
is
used to measure labor
productivity. Depending on each field
of
four sub-industries; Food processing, hotels and
restaurants, electronics and mechanics or textile, garment and footwear respectively,
GSO
(2007) set
up
suitable methods to calculate labor productivity that will
be
explained
in
details
in
later chapter: Research methodology.

aggregate production functions
is
central on much
of
today's work on growth,
technological change, productivity,
mid
labor. Empirical estimates
of
aggregate
production functions are a tool
of
analysis essential in macroeconomics and
microeconomics
as
well
as
important theoretical constructs, such as potential output,
technical change, or the demand for labor. The production function has the form as
follows:
(1)
Where:
• Y denotes output ,
L:
labor input,
K:
capital input
• A is a constant depending on the units
in
which inputs and outputs are measured
Pindyck and Rubinfeld production theory
Pindyck and Rubinfeld (1997) stated that the relationship between the inputs to the
production process and the resulting output is described by a production function
indicating the output Q that a
firm produces for every specified combination
of
inputs.
They assumed that a production function consists
of
two inputs, labor
Land
capital K and
it can be described as
Q=F(K,L)
(2)
This equation that applies to a given technology relates the quantity
of
output to the
quantities
of
the two inputs capital K and labor L. For instance, the production function
might describe the crop that a farmer can obtain with a specific amount
of
machinery and
workers. Because production function describes the maximum output feasible for a given
set
of
inputs in a technically efficient manner, it allows for inputs to be combined in
varying proportions to produce maximum output in many ways through labor-intensive
or
well as decreasing returns at high output levels might be real.

2.3.2.1.
Channel effects
of
foreign direct investment
In general perspective, FDI may effect
on
host countries in a number ways. According to
Vahter
(2004), the important channel effects
of
FDI
on
growth happen via technology
transfer and spillover effects. Foreign direct investment is considered a prominent force
of
growth for most
of
developing economies. Because it brings new capital, technology
and know-how from parent firms to
host
firms. However, Blomstrom and Kokko (1998)
who explain that the spillovers from FDI to host countries may occur through three
channels: knowledge shifts with skilled labor, technology transfer, and effective resource
allocation due to competition.

In
general, these effects are referred
to as
horizontal spillovers.
However, companies from sectors other than that

the foreign enterprise might be
affected by its presence as well
if
they are in direct business contact with
it.
This includes
companies that supply
or
provide services for foreign frrms, as well as companies that are
supplied by foreign frrms.
It
is
likely that foreign companies require higher standards
from their suppliers. In other words, it is also likely that higher standards are provided by
foreign companies to domestic companies as well, which might improve the domestic

companies' efficiency and performance. And these effects are referred to as vertical
spillovers.

2.4. Empirical studies
There are a great number
of
empirical studies estimating the impact
of
FDI on labor
productivity in many countries around the world. However the researches can be
separated into two groups; one which concludes that FDI enhances and improves the
productivity
of
domestic firms while the other argues that the impact
of
FDI is mixed,
unclear or even negative.
2.4.1. FDI impacts enhance labor productivity

skilled labors, size
of
firms positively affects labor productivity
of
the firms including
domestic and FDI firms. However the results did not indicate the impact
of
FDI that
differs significantly based on forms
of
FDI as well as varies across the provinces around
the countries. Moreover the test did not show the spillovers
of
FDI to labor productivity.
Making the same findings as authors mentioned above, Vani
(2000) undertook the
research on the impact and incidence
significant and positive in catching up states.
However the labor productivity
is
growing only at the expense
of
employment. This tends
to ponder that liberalization will make rich states richer with the poor states lagging
behind or there can be convergence across states through the presence ofFDI.
15
2.4.2. The opposite results
of
FDI impacts on labor productivity
While the above studies conclude that the impact
of
FDI on the labor productivity
is
clear
and positive however,
in
the research about the effects
of
FDI on labor productivity
in
Estonia and Slovenia, Vahter (2004) found out the results
ofthe
negative impacts
ofFDI
in Estonia and positive impacts in Slovenia. Besides that
he
also suggested that different
firms are active
in
the same market.
As
a
result, the productivity
of
domestic firms may fall as they are moving towards lower
output levels along their average cost curves.
In addition, the ideas that FDI has positive impact on the productivity
in
manufacturing
whereas its effects on growth
of
agriculture and mining sectors are negative through the
conclusion
of
Alfaro (2003)
who
