prices. The research investigated 241 officials, real estate investors, appraisers, and real estate
brokers on factors affecting residential land prices. Research results have shown 13 groups
with 45 factors affecting the price of residential land. The impact rates of the factor groups
range from 1.43% to 23.65%. The COVID-19 pandemic factor group has the strongest impact
on land prices, followed by other factor groups, including upgrading administrative units;
formulation and implementation of the planning; the real estate market; financial
economics; credit; real estate brokerage; infrastructure; location of the land parcel; particular
factors; juridical factors; environment and social security. To harmonize the interests of the
State, investors, and land users when valuing land, it is necessary to pay attention to the
factors that strongly impact land prices first, and then the smaller ones.

1. Introduction
In Vietnam, the land price is understood as the value
of land use rights of an area unit at a specific time and
in a specific location (National Assembly, 2013). The
land price is one of the legal bases for calculating land
use levy, land rent, taxes, fees, charges, and other
financial obligations related to land such as purchase
and sale of land use rights, and land lease, mortgage,
capital contribution, compensation for land when the
State recovers land, etc. (Bórawski et al., 2019; Han et
al., 2020; Jahangir, 2018; Mera, 1992; Nam et al., 2019;
Wang et al., 2019; Ping & Hui, 2010). To determine the
above amounts correctly and adequately, we must
first understand what factors affect land prices at
various times and locations (Bórawski et al., 2019;
Nam et al., 2021). Factors that affect land prices are
those that increase or decrease the land price of
specific parcels of land (Jiang et al., 2013; Kagel &
Levin, 1986). Factors affecting land prices are classified
into groups according to their characteristics. The
traditional groups of factors that can affect the land
price include a group of legal factors, a group of the
location of land plots; a group of individual factors; a
group of economic factors, a group of social
environmental factors, etc. (Dirgasová et al., 2017;
Downing, 1973; Hultkrantz, 1991; Le, 2017; Nam et al.,
2021; Ersoz et al., 2018).
The above researchers have only focused on
assessing the influence of one or several factors on
land prices based on inheriting the factors pointed out
from previous studies or assuming the factors that
may affect land prices by themselves on land prices
and then performing hypothesis testing. Therefore, it
is not possible to determine all the factors affecting

land prices. This is the research gap related to land
prices. Therefore, our study aims to propose a method
to identify factors affecting land prices, including
inherited factors from previous studies (traditional
factors) and new factors such as the COVID-19
pandemic, real estate brokerage activities, a policy of
upgrading administrative units, planning, etc.
Furthermore, the study also proposes some policy
implications related to land prices for the State, real
estate investors, valuation agencies, credit institutions,
etc.
To test the proposed method to solve the problem
that has been raised, the authors have studied the
factors affecting the price of residential land in Tu Son
city, Vietnam because, from 2017 to 2021, the price of
residential land might also be affected by many
factors, including both traditional and new factors, but
so far there has been no research on this issue. Tu Son
city is 15 km from the capital of Vietnam (Fig. 1). In
addition to the introduction, the article has four main
sections, including a literature review; data and
methods; results and discussion; conclusion, and
implications.

characteristics. The main groups affecting land prices
The factors affecting land prices determine whether
the price of a particular parcel of land rises or falls in
relation to the price of other parcels of land in that
area and at a given time. In different areas, land prices
may be affected by other factors and the level of their
impact is also different. Even in a certain area, at
different times, the land price is probably affected by
different factors due to changing socio-economic and
environmental conditions. The influencing factors,
although having certain differences, can be classified
into
groups
according
to
their
common
include location factors, socio-economic factors, legal
factors, infrastructure factors, individual factors,
security factors, social order, environmental factors,
credit factors, real estate market factors, etc.
The group of location factors includes factors such
as distance to the center, to markets, to schools, to
medical facilities, etc (Blatz, 1984; Downing, 1973; Lu
& Wang, 2020). The group of economic-financial
factors includes earning capacity of land plots, land
finance, and people's income level (Jiang et al., 2013;
Lu & Wang, 2020; Protopapas & Dimopoulos, 2019).

The group of legal factors includes the legal status of
the land plots, the restrictions on land use, the rights
of
land
users,
etc.
(Dirgasová
et
al.,
2017;
Kheir & Portnov, 2016). The group of infrastructure
elements includes a transportation system, energy
supply system, water supply, drainage system,
communication system, etc (Jiang et al., 2013). A
particular group of factors is the area, shape, direction,
and width of the land plots. The group of factors of
security and social order includes factors such as:
people's understanding and observance of the law,
and management of social order (Jiang et al., 2013).
The group of environmental factors includes factors
such as air environment, water environment, noise,
and waste collection and treatment (Dirgasová et al.,
2017; Kheir & Portnov, 2016; Simangunsong et al.,
2017). ). The group of credit factors includes the loan
interest rate, total amount borrowed, and loan
procedures (Hultkrantz, 1991; Kheir&Portnov, 2016).
The group of real estate market factors includes the
supply and demand for real estate and the forecast of
future market movements (Fan et al., 2021). In
addition to the groups of factors mentioned above,
there are several other factors affecting land prices
such as high-speed railway (Huang & Du, 2020),
urbanization (Jahangir Alam, 2018; Jiang et al., 2013),
or housing prices (Scott, 1983; Wen & Goodman,
2013), or land acquisition risk for socio-economic
development (Blatz, 1984; Jiang et al., 2013). Factors
affecting land prices are diverse and complex, vary in
space and time, and are not fixed (Mitsuta et al., 2012;
Scott, 1983).
There have also been several studies that have
evaluated the impact of each factor on land prices, for
example, land tax, legal regulations on land use,
changing political institutions, urbanization, or the
time required to create land banks (Bórawski et al.,
2019; Han et al., 2020; Jahangir, 2018; Mera, 1992;
Wang et al., 2019; Ping & Hui, 2010; Trung & Quan,
2019 ). According to Wang et al. (2019), land prices
are strongly influenced by land speculation. When the
level of speculation increases, the land prices also
increase proportionally. However, at a certain point,
land prices will fall because the supply of land is
greater than the quantity demanded. In Dhaka,
Bangladesh, real estate speculation also increased
land prices Jahangir Alam (2018). According to
research by Ping & Hui (2010), the factors affecting
land prices are urban infrastructure, available land
area, and urban transport capacity. Besides, the
expressway system has a strong influence on land
prices (Huang & Du, 2020). In Tokyo, land tax has an
impact on land prices (Mera, 1992). According to Wen
& Goodman (2013), land prices increase due to rising
housing prices. Similarly, according to Scott (1983),
land prices are affected by different factors in different
periods in the same area, including housing prices.
Besides, land price is also affected by legal,
socioeconomic, and location factors
(Protopapas & Dimopoulos, 2019) or loan interest rate
(Hultkrantz, 1991). The price of industrial land in China
is affected by the level of economic development,
population density, and location factors (Lu & Wang,
2020). Besides, real estate supply and demand factors
also affect land prices (Kheir & Portnov, 2016).
According to Huang & Du ( 2020), in urban areas,
high-speed railway increases land prices in suburban
areas of the city due to convenient transportation, so
the demand for land in the suburbs increases, causing
land prices to increase. Besides, economic, financial,
environmental, and demographic factors also affect
residential land prices (Kheir & Portnov, 2016; Mitsuta
et al., 2012; Scott, 1983).
In Vietnam, according to Hai & Huong (2017),
groups of factors affecting land prices include a group
of individual factors, a group of legal factors, a group
of infrastructure factors, a group of socio-economic
factors, a group of location factors, a group of
neighboring factors, a group of real estate supply and
demand factors. According to Hai & Huong (2017),
there are 4 main groups of factors affecting land
prices, including: urbanization, infrastructure,
environment, and land supply and demand. Research
by Phan & et al. (2017) also pointed out four groups
of factors affecting land prices, namely regional,
individual, economic, and social factors. Tran &
Nguyen (2021) noted that 28 factors belonging to 9
groups of factors that had an impact. The price of
residential land was most affected by the group of
factors of supply and demand for land use rights, the
group of factors such as the location of the land plot,
the group of factors of urbanization, and 6 other
groups of factors. Group of social factors affecting the
price of residential land. Research by Nam et al. (2021)
pointed out 10 factors affecting the price of residential
land, in which the location factor had the strongest
impact on the land price; land plots on major roads,
favorable for business, are priced significantly higher
than the prices of land plots in other locations.
According to Pham & Phan (2021), legal factors had
the most influence on land prices. Ho et al. (2020)
identified 6 groups of factors, including: infrastructure,

particular, economic, location, social, and legal, that
have an impact on residential land prices. In contrast,
according to research by Trung and Quan (2019), the
group of factors of supply and demand for land use
rights has the greatest impact on residential land
prices. According to research by Hai & Huong (2017),
location factors have the strongest impact on land
prices. Nam et al. (2021) assessing factors affecting
public land fund management also pointed out the
factor that had the strongest influence on specific land
prices when determining public land rent for the area
and location of the land plot. In addition, when
studying the factors affecting the land price of
winning land auctions, Nam et al. (2019) identified 6
groups of factors, of which the group of residential
land use rights market factors (supply and demand
and forecast of the land use right market) had the
strongest impact on the auction winning land price.
In addition to the above factors, there are some
other factors, such as the COVID-19 pandemic, the
policy of upgrading administrative units, and real
estate brokerage activities that may also affect land
prices, but there has been no research to assess the
extent of their influence compared to the factors that
are indicated previously. Therefore, this is an issue that
needs to be addressed in this article.
3. Data and Methods
3.1. Research steps
The study was carried out in 7 main steps (Fig. 2) to
determine the influencing factors, their impact rates,
and impact levels of each factor group on land prices.
Step 1 was to study the authors’ research results on
factors affecting land prices to synthesize groups of
influencing factors. Step 2 collected secondary data on
natural and socio-economic conditions of Tu Son city
related to land prices. Step 3 was to survey and collect
data on factors that may affect the price of residential
land using printed questionnaires. Step 4 processed
the collected data and builds a research model
assuming the factors affecting land prices. Step 5
investigated for the second time to determine the
impact of each hypothetical factor on land prices
according to the 5-level Likert scale. Step 6 verified
the collected data using SPSS20.0 software to remove
the factors that did not satisfy the test conditions.
Step 7 determined the level of impact of the groups of
factors and conducted discussion and proposed policy
implications related to land prices.

3.2 Data collection and hypothetical research
model
Secondary data on natural, socio-economic conditions
in the 2017-2021 period were collected at state
agencies in Tu Son city. Primary data on factors
affecting residential land prices were collected in July
2022. First, the study carried out a survey using
questionnaires of 241 people to grasp the factors
affecting the price of residential land in Tu Son city,
including officials directly related to residential land
prices, real estate investors, land appraisers, and real
estate agents. The questionnaire contains basic
information about survey respondents and 42
hypothetical factors affecting residential land prices
inherited from previous studies, including groups of
infrastructure, legal, and personal factors; distinctive,
environmental, socio-economic factors, etc. Each
factor had 2 corresponding options (affecting and not
affecting the price of residential land) for respondents
to choose one of the two. In addition, respondents
were also asked to add other factors that might affect
the price of residential land according to their
assessment. The results of data processing using
SPSS20.0 software showed that 56 factors probably
affected land prices, of which 14 factors were added
(distance to administrative centers, supermarkets,
workplaces, etc.) to the 42 elements already available.
To increase the accuracy of the collected data and
reduce the number of questionnaires in Step 2, as well
as reduce the cost of the investigation and the
number of times to test the model, the study selected
47 factors with a ratio of rating greater than 50%
(majority) of the total number of respondents. The
remaining 9 factors (land buyers' tastes, distance to
historic sites, land taxes, traffic density, etc.) with a rate
of less than 50% (minority) were excluded. The
selected elements were classified according to their
properties into 13 groups. Each group was considered
a latent variable or an independent variable and had 3
to 6 factors. The factors belonging to the groups were
called observed variables (Table 1). Some additional
factors that might impact residential land prices
included the magnitude of the impact of the COVID-
19 pandemic, its prevention, and control measures, its
repetition cycle; factors related to real estate
brokerage, administrative unit upgrading, land use
planning, etc. (Table 1). The model that assumed
factors affecting residential land price was shown in
(Fig. 3).

the survey in the previous step. The content of the
questionnaire consisted of 47 factors selected in
Step 1. Each factor has 5 corresponding ratings
according to the Likert scale (very impactful - 5 points,
quite impactful - 4 points, medium impactful). - 3
points, little impactful - 2 points, very little impactful -
1 point) (Likert, 1932) for respondents to choose 1 out
of 5 levels for each factor. In addition, respondents
were also asked to write down comments to clarify the
impact of factors on residential land prices.
According to Hoang & Nguyen (2008), the number
of survey samples was determined based on the
requirements of the exploratory factor analysis (EFA)
with at least 5 observations for 1 measurement
variable (n1 = 5* p). Therefore, with 47 measuring
variables
belonging
to
13
groups

factors,

this study, a load weight must be greater than 0.35.
Besides, the scale is only accepted when the total
variance explained is greater than 50%; Barlett’s
coefficient with Sig significance level less than 0.05 to
ensure the factors are correlated with each other;
Eigenvalue coefficients must be greater than 1 to
ensure the groups of factors are different.
The impact level of each factor on land prices is
determined according to the value of the impact index
according to 5 levels (Very impactful - the impact
index 4,20; quite impactful - the impact index 3,40 ÷
4,19; medium impactful - the impact index 2,60 - 3,39;
little impactful - the impact index 1,80 ÷ 2,59; very
little impactful - the impact index < 1,80) (Likert,
1932). The impact index of each factor is determined
according to formula 2 (Nam & Yen, 2022).

reliability of the data, the study selected a sample
equal to 241 (equal to the number of people who
answered the first survey).
The hypothetical research model was tested
through testing criteria including Cronbach's Alpha
coefficient, KMO coefficient, Bartlett test, and
Eigenvalues coefficient. The reliability of the scale was
tested by Cronbach's Alpha coefficient (Cronbach,
1951). The scale can be used when the Cronbach

shorten many measurement variables into a set of
variables (factors) to make them more meaningful but
still contain most of the information of the original set

assessed through the KMO appropriate coefficient,
Bartlett test, Eigenvalues coefficient, total explanatory
variance, and factor loading. Variables are only
accepted when KMO is in the range from 0.5 to 1.0
and its weight factors in other factors are less than
0.35 (Igbaria et al., 1995). According to Hair et al.

4. Results and Discussion
The results of assessing the reliability of the scale
through Cronbach's Alpha coefficient for 13 groups of
factors showed that Cronbach's Alpha coefficient
ranged from 0.709 to 0.915 (Table 2). The correlation
coefficient of most of the observed variables was
72
greater than 0.3, satisfying the test conditions, except
that the variables for distance to the city center and
the market had values of less than 0.3 (Table 2).
Therefore, these two observed variables were
excluded, and the second test was performed. The
results of the second test showed that the test criteria
met the requirements (Table 3). Thus, the scale that
was used to evaluate the factors affecting the price of
residential land was reliable and suitable for further
analysis. The suitability test of the EFA was carried out
through the KMO suitability coefficient. The KMO was
equal
to
0.893
and
satisfied
the
condition
0.500
<KMO< 1.000, so exploratory factor analysis was
appropriate with actual data. Besides, the results of
the Barlett test indicated that the Sig value was equal
to 0.000 and less than 0.050 (Table 4). This proved that
the measured variables were linearly correlated with
the representative factor.
The load factor coefficients of the components
were all greater than 0.60 (Table 5), so the EFA analysis
had practical significance, and the independent
variables ensured accuracy.

According to Table 6, the Sig Pearson correlation
of independent variables CO, AD, PL, IN, PA, LO, SO,
and EN with dependent variable Y was less than 0.05,
so there was a linear relationship between the
independent variables and the dependent variable.
The CO variable and Y variable had the strongest
relationship with the r coefficient of 0.821. SO variable
and Y variable had the weakest relationship with the r
coefficient of 0.253. This ensured eligibility for
multiple linear regression analysis.
The results of the multivariate regression analysis
in Table 7 showed that the Sig coefficients were all
smaller than 0.005, so the regression model was
significant, and the independent variables had an
impact on the dependent variable Y. The adjusted R2
value equal to 0.873 showed that the independent
variables included in the regression affected 87.3% of
the change of the dependent variable (residential land
price), and the remaining 12.7% were due to variables
outside the model and random error. Besides, the
Durbin-Watson coefficient had a value of 1.859,
ranging from 1.5 to 2.5, so no first-order sequence
autocorrelation occurred (Table 7). The variance

The impact indexes of factor groups and each
factor on residential land prices were shown in Table
8. Of the 13 factor groups, four of them had the
strongest impact on residential land prices, including a
group of COVID-19 pandemic factors, a group of
factors for upgrading administrative units, a group of
economic-financial factors, and a group of credit
factors. Four groups of factors had a medium level of
impact on residential land prices, including
infrastructure factors, individual factors, and land plot
location factors. Three factor groups had an average
impact on land prices including the group of factors
for planning and implementing the plan, the group of
factors for social security and order, and the group of
real estate brokerage factors. Two groups that had
little impact on land prices included environmental
factors and legal factors.
The impact index of individual factors ranged from
1.20 to 4.96. The most influential factor was the impact
of the COVID-19 pandemic, and the smallest
influential factor was the form of real estate brokerage
(Table 8).

The results in Tables 3 and Table 8 show that
residential land prices are affected by 55 factors
belonging to 13 groups of factors. Compared with the
results of previous studies, this study showed more
factors and more groups of factors. Groups of factors
that are different from the previous groups of factors
include the group of COVID-19 pandemic factors, the
group of real estate brokerage elements, and the
group of administrative and planning elements. Some
weak groups have the same name, but their factors
can also be similar to and different from those pointed
out in previous studies, including real estate market
factors; a group of economic factors; a particular
group of factors. The research results also show that
the impact rates of factors on land prices are also
different and also different from the impact rates of
the groups of factors that have been shown in
previous studies. The group of COVID-19 pandemic

factors and the group of real estate brokerage factors
are both new and have the highest impact rate (Table
8). Moreover, their factors also have a strong impact
on land prices (Table 8). This is the difference
compared with the research results of Tra et al. (2020)
because the infrastructure factor had the largest
impact rate. Nguyen's research (2017) showed that the
distance to political centers, schools, hospitals, etc has
the strongest impact on land prices. According to
Phan et al. (2017), regional factors had the strongest
impact. The main reasons are that the studies were
carried out in different locations with different natural,
socio-economic and disease conditions.
The impact rates of 13-factor groups on land prices
range from 1.43% to 23.65% (Fig. 4). The group of
COVID-19 pandemic factors has the largest impact,
followed by the group of real estate brokerage factors,
the group of urbanization factors, industry,
handicrafts, and other groups of factors. The group of
individual factors including the area of the land plot,
the shape of the land plot, the width of the facade,
etc. has the smallest impact ratio because the land
plots have the same area, shape, and width as the
facade and meet the requirements. meet the needs of
land users. The average impact indexes of the groups
of factors are also different and range from 2.07 to
4.50 (Fig. 5). The group of COVID-19 pandemic factors
has the largest impact index, and the group of
environmental factors has the smallest impact index
because Tu Son city has good environmental
conditions. Thus, the group of COVID-19 pandemic
factors has both the largest impact rate and the
largest impact index on residential land prices.
From the above analysis, it can be seen that in the
traditional factors affecting land prices, the distance to
the center does not affect land prices because Tu Son
city has a small area, a good transportation system,
and infrastructure works are evenly distributed. The
COVID-19 pandemic factor was a temporary factor
that occurred for a short time but, nevertheless, also
affected land prices. In addition, new factors specific
to the study area, such as the policy of upgrading
administrative units, real estate brokerage activities,
and planning, had an influence on land prices.

5. Conclusion and implications
The price of residential land in the study area is
affected simultaneously by 45 factors belonging to 13
groups of factors. The group of COVID-19 pandemic
factors has the strongest impact (impact rate of
23.65%) on residential land prices. The group of social
order and security factors has the smallest impact
(rate of 1.43%) on residential land prices. The impact
indexes of factors on land prices range from 1.20 to

4.96. For the price of residential land to be more
suitable for the interests of the State, individuals, and
organizations, it is necessary to pay attention to the
impact level of the factors when determining the land
price. First, it is essential to pay attention to the
groups of factors that have the most substantial
impact on land prices, then the groups of factors with
smaller impact rates. In particular, when planning
financial policies on land, the State needs to pay
attention to epidemic factors and prevention
measures to have solutions to ensure appropriate
budget revenue and achieve the set plan. The research
method in this article can be used as a reference when
studying issues related to residential land prices. The
study has not assessed the factors that cause the
residential land price to change, so this issue needs to
be further studied.
