According to Figure 2.2 and the above table, the Asian market is Vietnam's main export market in the period of 2018 - 2019. The number of tourists from Asian countries to Vietnam accounts for a large proportion. In 2019, the number of Korean and Chinese tourists was 4,290,802 and 5,806,425, respectively, accounting for more than 70% of the total number of Asian visitors and 56.06% of the total number of international visitors to Vietnam. The growth rate of the Korean and Chinese markets increased by about 15-20% per year. In the first month of March 2020, the number of Asian visitors still accounted for 72.54% of the total number of international visitors to Vietnam.
Regarding the structure of visitors by region, Asian markets account for the majority (79.9%), of which Northeast Asia accounts for 66.8%, Southeast Asia accounts for 11.3%, and the remaining Asian countries account for 1.8%, showing the importance of nearby markets in the Asian region. European markets account for 12%, America accounts for 5.4%, and Australia accounts for 2.4%. The large proportion of the Asian market is also a common feature of countries in the region: Asian visitors to Malaysia account for 90%, of which Singapore 2 visitors account for 40%. Asian visitors to Thailand account for 75%, of which Chinese visitors account for 28%.
In the overall strategy for Vietnam tourism development in 2020, with a vision to 2030, the Vietnamese tourism industry identifies the Northeast Asian market as a potential market. The basis for building this strategy is based on the needs and travel preferences of Northeast Asian tourists as well as their ability to pay for travel. In general, tourism spending of Northeast Asian visitors tends to increase steadily compared to previous years and is higher than the average of international visitors to Vietnam. According to the latest statistics of the General Statistics Office in 2019, in the Northeast Asia region, visitors from China have the highest average daily spending of 135.2 USD/person, followed by Japanese visitors with an average of 132 USD/person, and Korean visitors with an average of 127.2 USD/person. China is also the country that spends the most for the whole trip with 1021.66 USD, followed by Japan with 935.24 USD, and finally Korea with an average total trip spending of 872.14 USD (General Department of Tourism, 2019). With a large market share of tourists and high spending, Northeast Asian tourists contribute significantly to the growth and development of Vietnam's tourism industry.
With its Eastern culture and similar religious features, Vietnam is always a destination for international tourists with many cultural activities and festivals. If not affected by the Covid-19 epidemic, Vietnam could completely aim to welcome about 14.35 million Asian visitors in particular and 20.5 million international tourists in general.
Structure of tourists by travel purpose
If divided by the main purpose of the trip, pure tourists accounted for 59.71% in 2019. In particular, the number of foreigners coming to Vietnam for work purposes also increased rapidly. In the first 4 months of 2019, business tourism accounted for 19.68% (the whole year of 2019 was 16.93%), or through commercial purposes to find markets...
The World Tourism Organization (UNWTO) predicts that by 2030, tourists traveling for the purpose of visiting, health, and religion will account for 31% of total tourists; for the purpose of visiting, relaxing, playing, and entertaining will account for 54%; for the purpose of work and career will account for 15%. According to this forecast, in the coming time, global tourism will continue to grow according to the following main trends: Global tourism demand is booming, especially among the growing middle class in China, creating significant economic opportunities for destinations in Southeast Asia. The country of a billion people has become the world's largest source market and will strongly impact the tourism development policies of many countries.
The purpose of most tourist markets is still sightseeing, relaxation, entertainment, but many new needs will be formed. Tourists are increasingly interested in the need to experience new values established on the basis of traditional cultural values (distinction, uniqueness, originality), natural values (primitiveness, uniqueness), creative values and high technology (modernity, convenience). In particular, medical and health care tourism is increasingly popular. Developing responsible tourism, ecotourism and community tourism is both a trend and an inevitable requirement for the tourism industry to implement the principles and goals of sustainable development.
The UNWTO estimates that Southeast Asia will become the 4th largest international tourist attraction region in the world, and Vietnam is one of the 10 countries with the fastest tourism growth rate. The world tourism industry is witnessing the development of many different tourism trends such as: self-designed tours, luxury tours, adventure tourism, experiential tourism, leisure tourism with modern equipment... In the face of this wave, domestic travel agencies must also invest more in building tour products to meet market demand and meet the purposes of international passengers.
Currently, simple vacations are no longer a popular choice. Tourists are more interested in the quality of experiences at the destination. Tourists will stay longer if the destination has many interesting experiences. If in the past, beach tourism was popular, in recent years it has shifted to mountain resorts and experiencing local culture. This is an opportunity for Vietnam to improve and invest in many aspects to build the country's image to foreign tourists while improving the quality of services, facilities, and ensuring human resources to be competitive and attract foreign tourists.
Spending structure of international visitors
According to the 2019 annual report of the General Department of Tourism, the spending of international visitors to Vietnam in the survey includes the spending of visitors in Vietnam from the time of entry to exit. Overnight visitors spend an average of 1,074 USD/person, travel to Vietnam for 8.1 days, spend an average of 132.6 USD/day. Daytime visitors spend an average of 99.86 USD/person. Overnight visitors at CSLT spend an average of 1,083.36 USD/person, the length of the trip is 8.02 days, the average spending per day is 135 USD/day. Overnight visitors not at the accommodation facility (stay at friends' or relatives' houses...) spend an average of 622.71 USD, the length of the trip is 11.92 days.

Figure 2.3 Average spending structure of an international visitor to Vietnam staying overnight at an accommodation facility in 2019

Figure 2.4 Average spending structure of international visitors to Vietnam per day in 2019
International visitors to Vietnam mainly spend on 4 main purposes: accommodation services, food services, transportation and shopping. Thus, it can be seen that revenue from tourism service exports mainly comes from room services and food services. With more than 18 million visitors in 2019, Vietnam can see that it is necessary to develop accommodation facilities to meet the number of visitors that may increase in the coming period, raising
Improve service quality and develop additional services to bring more revenue to tourism activities.

2.2.2.3 Current status of revenue from international tourists
Figure 2.5 Total revenue from international tourists in the period 2015 - 2019
Of the total revenue from tourists, the total revenue from international tourists is considered the on-site export value, bringing foreign currency to the country. In 2019, the total revenue from tourists reached 755 trillion VND (equivalent to 32.8 billion USD), of which:
- Total revenue from international tourism was 421 trillion VND, accounting for 55.7%, equivalent to 18.3 billion USD of export value from tourism.
- Total revenue from domestic tourism is 334 trillion VND, accounting for 44.3%, equivalent to 14.5 billion USD.
In total revenue from tourists, total revenue from international tourists is considered as on-site export value, bringing foreign currency to the country. Along with the development of the domestic economy, people have more and more opportunities and needs to travel.
According to the annual report of the General Department of Tourism, in the period from 2015 to 2019, tourism service export revenue has grown steadily and clearly. Since joining the WTO, the service market in general and tourism services in particular have improved, and exports of goods and services have been boosted. From 2015 to
In 2019, the growth rate was up to 13.53% compared to 2015 and 9.9% compared to 2018. The on-site export value of tourism increased 2.1 times from 8.57 billion USD to 18.3 billion USD, an average increase of 20.9%/year.
In general, in the period of 2015 - 2019, each year the Vietnamese tourism industry has attracted millions of international tourists to visit and relax. The increase in the number of international visitors means that export turnover through tourism in Vietnam has grown significantly in recent years. This proves that the Vietnamese tourism industry is on the rise and promoting its image in the international arena and has been specifically demonstrated by the number of international visitors to Vietnam in 2019 reaching more than 18 million visitors.
According to the General Statistics Office's year-end report, in 2020, due to border closures to prevent Covid-19, international visitors to Vietnam only reached about 3.7 million, down 79.5% compared to 2019; domestic visitors reached 56 million, down 34.1%; total tourism revenue reached 312 trillion VND, down 58.7% - a decrease equivalent to 19 billion USD.

- 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)

Spending, Accommodation and Demand for Goods and Tourism Services of International Tourists
(According to General Statistics Office of Vietnam)
Revenue from accommodation and travel establishments increased gradually from 2016 to 2019. For accommodation and travel establishments, the average revenue growth rate was about 9.5% per year. In 2019, revenue from accommodation establishments reached 64.5 trillion VND, an increase of 8.96% compared to 2018, revenue from travel establishments increased by 9.63% compared to 2018, an increase of nearly 4 trillion VND.
The number of international tourists increasing each year is the main factor that helps the revenue of the establishments increase steadily and the profit from tourism services also increases. This shows that the supply of these establishments always meets the service demand with the number of visitors increasing each year. With a guaranteed profit, the more establishments and service providers open, the more tourists have the choice of accommodation and travel establishments with corresponding service quality.

International travel business
According to the General Department of Tourism, as of 2019, the number of international travel businesses was 2,667, of which the number of limited liability companies accounted for 62.4%, joint stock companies accounted for 36.3%, the remaining 1.4% were private enterprises and foreign-invested enterprises. Many travel businesses have been proactive in
The establishment of representative offices abroad is the basis for on-site promotion and attracting visitors from key markets. The increase in the number of international travel businesses has significantly contributed to improving the capacity of Vietnam's tourism industry, affirming that Vietnam's tourism is capable of welcoming international visitors from all over the world.
The tourism business environment is increasingly favorable, administrative procedures for tourism business have been amended in a more open direction, creating conditions for a rapid increase in the number of newly established tourism businesses. The General Department of Tourism always closely coordinates with functional agencies to strengthen inspection of tourism business activities in many provinces/cities to ensure the business environment and service quality.

(According to General Department of Tourism)
The tourism infrastructure system is increasingly improved, both in quality and quantity. In 2011, the country had 13,756 accommodation establishments, with a total of 256,739 rooms, by 2019, it increased to 30,000 accommodation establishments with 650,000 rooms. The average growth rate of the number of accommodation rooms in the period 2015 - 2019 reached about 12.3%/year, the average room occupancy rate reached about 59%/year. The types of accommodation are increasingly diverse, from high-class accommodation establishments (4-5 star hotels, high-class tourist apartments, tourist villas) to 1-3 star hotel systems, tourist motels, houses with rooms for tourists to rent (homestay), tourist villages, tourist accommodation ships,...

- 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)
