2.1. Research location
2.1.1. Ha Long City
2.1.1.1. Natural conditions
a. Geographical location
Ha Long City stretches from 20 0 55' to 21 0 05' north latitude, 106 0 50' to 107 0 30' east longitude.
North - Northwest borders Hoanh Bo district.
The South leads to the sea through Ha Long Bay and Hai Phong city. The East - Northeast borders Cam Pha city.
West - Southwest borders Yen Hung district.
Ha Long City is located in the center of the Province, with a land area of 27,195.03 hectares, with National Highway 18A running through it, forming the length of the City, with a seaport, a 50km long coastline, and Ha Long Bay, twice recognized by UNESCO as a World Heritage Site with an area of 434km2 .
b. Terrain
Ha Long City has a diverse and complex terrain, is one of the oldest formed areas in Vietnam, including hills, valleys, coastal areas and islands.
c. Climate
- Wind: Wind speed varies greatly from place to place. Offshore islands have very high wind speed, with an annual average of 5 m/s, rarely calm winds (≤3%), sometimes wind speeds reach over 40 m/s. Winter is from October of the previous year to March of the following year, influenced by the northeast monsoon. Summer is from May to August, mainly south and southeast winds blowing in from the sea.
- Temperature : Average annual temperature is above 20 o C - 25 o C.
- Rain - humidity: Ha Long is one of the rainy regions in the North with an average rainfall of 1800-2000mm/year, but the spatial distribution is very different. The average annual rainfall in the area is from 2000mm to 2400mm. The rainy months are from May to September.
d. Plants
Due to favorable climate and terrain conditions, the flora of Quang Ninh province is quite rich, with components belonging to many different migration streams such as natural forest vegetation, man-made vegetation, landscape and biodiversity.
e. Natural resources
Quang Ninh in general and Ha Long in particular have extremely rich natural resources. The prominent mineral resources are coal and limestone. Not only that, Ha Long also has extremely famous tourism and human resources, which is the world natural heritage Ha Long Bay.
2.1.1.1. Socio-economic and environmental conditions
a. Socio-economic conditions
Ha Long is a peak of the northern industrial triangle of Hanoi - Hai Phong - Quang Ninh. Coal mining has been established for a long time and has become a strength of the city with many large coal mines: Ha Tu, Ha Lam, Tan Lap, Nui Beo and dozens of small mines, each year exploiting over 10 million tons of various types of coal. Associated with the coal mines are screening plants, mechanical engineering, transportation enterprises and ports.
Ha Long strongly develops shipbuilding industry, construction materials production, seafood processing.
Ha Long City is a major trading center. Its main exports are coal and seafood, while its imports are petroleum, mining machinery, iron and steel, and means of transport. Ha Long is a hub for trading industrial goods, food, and foodstuffs for production and consumption in the mining and tourism industries.
Ha Long is a tourist city; the largest tourist center in the North and the number of tourists ranks second after Ho Chi Minh City.
b. Environmental conditions
Ha Long City has Ha Long Bay, a World Natural Wonder, and preserving the value of the wonder must be a top priority. The bay’s environment, from the belt, buffer zone to the outcrop, must be strictly protected. Because Ha Long is a city that develops tourism and the coal mining industry, environmental issues are given great attention.
Currently, the city has a clear plan: Bai Chay area, tourism development, where infrastructure is invested to serve tourism purposes, and coal production area concentrated in the north of Hon Gai area.
Tourism development is accompanied by a large amount of waste and wastewater. The problem of waste has been focused on by businesses, thoroughly collected, not affecting the urban beauty. In addition, the problem of collecting solid waste from residential areas is also implemented by wards and communes. Domestic wastewater from restaurants and hotels has been connected to the centralized wastewater treatment system in Cai Dam.
In Ha Long, the "smoke industry" goes hand in hand with the "smokeless industry". Previously, the environmental pollution in Ha Long city was always a serious problem .
received attention from the people and the government because coal companies are increasingly increasing their capacity.Mining efficiency, most mine wastewater and waste rock are acidic, high turbidity
are all dumped directly into the bay without any treatment process. At the portsCoal, the transportation and loading of coal in the "absolute protection zone" still exists.Many large tonnage ships coming to receive coal could not enter the port and had to use measures.transport, so a lot of coal spilled into Ha Long Bay. However, due to thedirection of departments of Quang Ninh province and Ha Long city, currently, the environment
The city's schools have been significantly improved. Open-pit coal mining has beenminimize to limit environmental pollution. Vinacomin has invested in buildingworks, centralized mine wastewater treatment systems. Coal mining is notalso spread across the city but concentrated in some areas such as Ha Lam,Ha Trung, Ha Tu.
2.1.2. Cam Pha City
2.1.2.1. Natural conditions
Cam Pha city is located about 200 km northeast of Hanoi capital, 30 km from Ha Long city, with geographical coordinates from 20 o 58'10 - 21 o 12' north latitude, 107 o 10' - 107 o 23'50 east longitude.
Cam Pha City has a natural area of 486.45 km², the terrain is mainly mountainous. Mountains and hills account for 55.4% of the area, midlands 16.29%, plains 15.01% and sea areas account for 13.3%. Offshore are hundreds of small islands, mostly limestone islands. The average annual temperature is about 23 degrees Celsius , the average humidity is 84.6%, the annual rainfall is 2,307 mm, and there is often fog in winter.[12]
2.1.2.1. Socio-economic and environmental conditions
Cam Pha City has a lot of potential for economic development such as coal mining and processing industry, construction materials production, mechanics, electrical equipment manufacturing, mining machines, heavy trucks, shipbuilding industry, trade services, tourism... In 2011, the economic growth rate was over 14%, the city's budget revenue was 751 billion VND, and the average income per capita reached 2,300 USD.
The main mineral reserve of Cam Pha is coal, with a total estimated potential of over 3 billion tons out of the total 8.4 billion tons of coal reserves of the entire Quang Ninh province. Cam Pha has a railway system for transporting coal running along the city to transport coal to Cua Ong Coal Selection Plant, large coal mines such as Coc Sau, Deo Nai, Cao Son, Mong Duong, Khe Cham, Duong Huy, Thong Nhat. In addition, other minerals such as antimony, limestone, and mineral water are all rare resources. The limestone mountains in Cam Pha are an abundant source of raw materials for the development of cement, thermal power, and construction materials industries, with the Cam Pha Cement Factory. Cam Pha city has a seafood exploitation industry with more than 50 km of coastline, but mainly inshore fishing, with low output.[3]
Cam Pha City is one of the major coal mining centers in the country, so the amount of soil, rock, wastewater and dust discharged into the environment every year is very large. In order to overcome the negative impacts caused by coal mining activities, in recent times
The coal industry has continuously invested and innovated technology for environmental protection (EP) in this area. To promote dust reduction, up to now, Vinacomin has also completed the pilot construction of 1 automatic car wash station at Coc Sau Coal Joint Stock Company and 2 car wash stations at Cua Ong Coal Selection Company. Based on the existing stations, experiences will be drawn to continue investing in car wash stations on the roads from the mines and coal ports. The goal is that after 2020, all vehicles will be washed before entering urban areas. In recent years, in some localities in the city, land subsidence has occurred, creating large holes that people often call "death holes". Other environmental problems arising from coal mining activities include dust, impact on groundwater, surface water, erosion, and leaching from waste dumps when the rainy season comes.

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in people's daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone company's network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)

- Test the relationship between demographic variables and consumer behavior for Mobile Marketing activities
The analysis method used is the Chi-square test (χ2), with statistical hypotheses H0 and H1 and significance level α = 0.05. In case the P index (p-value) or Sig. index in SPSS has a value less than or equal to the significance level α, the hypothesis H0 is rejected and vice versa. With this testing procedure, the study can evaluate the difference in behavioral trends between demographic groups.
CHAPTER 4
RESEARCH RESULTS
During two months, 1,100 survey questionnaires were distributed to mobile phone users in the inner city of Hanoi using various methods such as direct interviews, sending via email or using questionnaires designed on the Internet. At the end of the survey, after checking and eliminating erroneous questionnaires, the study collected 858 complete questionnaires, equivalent to a rate of about 78%. In addition, the research subjects of the thesis are only people who are using mobile phones, so people who do not use mobile phones are not within the scope of the thesis, therefore, the questionnaires with the option of not using mobile phones were excluded from the scope of analysis. The number of suitable survey questionnaires included in the statistical analysis was 835.
4.1 Demographic characteristics of the sample
The structure of the survey sample is divided and statistically analyzed according to criteria such as gender, age, occupation, education level and personal income. (Detailed statistical table in Appendix 6)
- Gender structure: Of the 835 completed questionnaires, 49.8% of respondents were male, equivalent to 416 people, and 50.2% were female, equivalent to 419 people. The survey results of the study are completely consistent with the gender ratio in the population structure of Vietnam in general and Hanoi in particular (Male/Female: 49/51).
- Age structure: 36.6% of respondents are <23 years old, equivalent to 306 people. People from 23-34 years old
accounting for the highest proportion: 44.8% equivalent to 374 people, people aged 35-45 and >45 are 70 and 85 people equivalent to 8.4% and 10.2% respectively. Looking at the results of this survey, we can see that the young people - youth account for a large proportion of the total number of people participating in the survey. Meanwhile, the middle-aged people including two age groups of 35 - 45 and >45 have a low rate of participation in the survey. This is completely consistent with the reality when Mobile Marketing is identified as a Marketing service aimed at young people (people under 35 years old).
- Structure by educational level: among 835 valid responses, 541 respondents had university degrees, accounting for the highest proportion of ~ 75%, 102 had secondary school degrees, ~ 13.1%, and 93 had post-graduate degrees, ~ 11.9%.
- Occupational structure: office workers and civil servants are the group with the highest rate of participation with 39.4%, followed by students with 36.6%. Self-employed people account for 12%, retired housewives are 7.8% and other occupational groups account for 4.2%. The survey results show that the student group has the same rate as the group aged <23 at 36.6%. This shows the accuracy of the survey data. In addition, the survey results distributed by occupational criteria have a rate almost similar to the sample division rate in chapter 3. Therefore, it can be concluded that the survey data is suitable for use in analysis activities.
- Income structure: the group with income from 3 to 5 million has the highest rate with 39% of the total number of respondents. This is consistent with the income structure of Hanoi people and corresponds to the average income of the group of civil servants and office workers. Those
People with no income account for 23%, income under 3 million VND accounts for 13% and income over 5 million VND accounts for 25%.
4.2 Mobile phone usage in Hanoi inner city area
According to the survey results, most respondents said they had used the phone for more than 1 year, specifically: 68.4% used mobile phones from 4 to 10 years, 23.2% used from 1 to 3 years, 7.8% used for more than 10 years. Those who used mobile phones for less than 1 year accounted for only a very small proportion of ~ 0.6%. (Table 4.1)

The survey indexes on the time of using mobile phones of consumers in the inner city of Hanoi are very impressive for a developing country like Vietnam and also prove that Vietnamese consumers have a lot of experience using this high-tech device. Moreover, with the majority of consumers surveyed having a relatively long time of use (4-10 years), it partly proves that mobile phones have become an important and essential item in peoples daily lives.
When asked about the mobile phone network they are using, 31% of respondents said they are using the network of Vietel company, 29% use the network of
of Mobifone company, 27% use Vinaphone companys network and 13% use networks of other providers such as E-VN telecom, S-fone, Beeline, Vietnammobile. (Figure 4.1).
Figure 4.1: Mobile phone network in use
Compared with the announced market share of mobile telecommunications service providers in Vietnam (Vietel: 36%, Mobifone: 29%, Vinaphone: 28%, the remaining networks: 7%), we see that the survey results do not have many differences. However, the statistics show that there is a difference in the market share of other networks because the Hanoi market is one of the two main markets of small networks, so their market share in this area will certainly be higher than that of the whole country.
According to a report by NielsenMobile (2009) [8], the number of prepaid mobile phone subscribers in Hanoi accounts for 95% of the total number of subscribers, however, the results of this survey show that the percentage of prepaid subscribers has decreased by more than 20%, only at 70.8%. On the contrary, the number of postpaid subscribers tends to increase from 5% in 2009 to 19.2%. Those who are simultaneously using both types of subscriptions account for 10%. (Table 4.2).

The above figures show the change in the psychology and consumption habits of Vietnamese consumers towards mobile telecommunications services, when the use of prepaid subscriptions and junk SIMs is replaced by the use of two types of subscriptions for different purposes and needs or switching to postpaid subscriptions to enjoy better customer care services.
In addition, the majority of respondents have an average spending level for mobile phone services from 100 to 300 thousand VND (406 ~ 48.6% of total respondents). The high spending level (> 500 thousand VND) is the spending level with the lowest number of people with only 8.4%, on the contrary, the low spending level (under 100 thousand VND) accounts for the second highest proportion among the groups of respondents with 25.4%. People with low spending levels mainly fall into the group of students and retirees/housewives - those who have little need to use or mainly use promotional SIM cards. (Table 4.3).

The statistics in Table 4.3 are similar to the percentages in the NielsenMobile survey results (2009) with 73% of mobile phone users having medium spending levels and only 13% having high spending levels.
The survey results also showed that up to 31% ~ nearly one-third of respondents said they sent more than 10 SMS messages/day, meaning that on average they sent 1 SMS message for every working hour. Those with an average SMS message volume (from 3 to 10 messages/day) accounted for 51.1% and those with a low SMS message volume (less than 3 messages/day) accounted for 17%. (Table 4.4)

Similar to sending messages, those with an average message receiving rate (from 3-10 messages/day) accounted for the highest percentage of ~ 55%, followed by those with a high number of messages (over 10 messages/day) ~ 24% and those with a low number of messages received daily (under 3 messages/day) remained at the bottom with 21%.

When comparing the data of the two result tables 4.4 and 4.5, we can see the reasonableness between the ratio of the number of messages sent and the number of messages received daily by the interview participants.
4.3 Current status of SMS advertising and Mobile Marketing
According to the interview results, in the 3 months from the time of the survey and before, 94% of respondents, equivalent to 785 people, said they received advertising messages, while only a very small percentage of 6% (only 50 people) did not receive advertising messages (Table 4.6).

The results of Table 4.6 show that consumers in the inner city of Hanoi are very familiar with advertising messages. This result is also the basis for assessing the knowledge, experience and understanding of the respondents in the interview. This is also one of the important factors determining the accuracy of the survey results.
In addition, most respondents said they had received promotional messages, but only 24% of them had ever taken the action of registering to receive promotional messages, while 76% of the remaining respondents did not register to receive promotional messages but still received promotional messages every day. This is the first sign indicating the weaknesses and shortcomings of lax management of this activity in Vietnam. (Table 4.7)
