have strong and fanatical beliefs in religion. Besides, the cultural ethics in this society are also very strict. They promote loyalty, obedience, hate lies, and favor men over women.
2.2. Characteristics of Eastern culture
As presented in the previous sections, Eastern culture is a culture that is large in scale, territory, diverse in color and has existed for a very long time in terms of history. Therefore, generalizing the characteristics of this culture is not simple. Besides, there are currently many ways to generalize the characteristics of Eastern culture. However, within the framework of the research topic, the author would like to choose to generalize Eastern culture with four main characteristics: Eastern culture has a strong agricultural and rural character; Eastern culture focuses on community and emotional behavior, flexibility in relationships between people; Eastern culture is harmonious, follows nature, takes advantage of nature to serve human life, and Eastern culture promotes traditional values, does not like change 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 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)

Factors affecting consumer behavior towards Mobile Marketing activities in Hanoi inner city area - 1 -
General Model of Consumer Behavior According to Kotler (2004) -
Some Common Characteristics of Ethnic Minority Culture in Quang Nam Province
2.2.1. Eastern culture has strong rural agricultural characteristics.

The rural agricultural character is the most prominent feature, the most visible identity of Eastern culture. First of all, Eastern society is an agricultural society. The traditional production of Eastern societies is mainly agricultural production. Moreover, the natural conditions here are extremely favorable for the development of agriculture. That is why Eastern culture has been an agricultural culture from the very beginning, and this feature is evident here until now. Thus, agricultural production is closely associated with Eastern countries and is the basis for creating a type of agricultural-based culture, creating the identity
7 Prof. Dr. Mai Ngoc Chu (editor) (2008), Introducing Oriental Culture , Hanoi Publishing House
Agricultural and rural characteristics in Eastern culture. Agricultural and rural characteristics are expressed in many cultural aspects:
First of all, the agricultural-rural character is reflected in the material culture related to the basic needs of people such as eating, wearing, and living. The main food source of Eastern people is rice - a product of wet rice plants and cereals produced by agricultural production. Eastern people often eat rice with self-sufficient foods such as vegetables, fish, and some types of poultry meat... Spices such as chili, pepper, herbs, curry... which are products of agricultural production, are also commonly used in many places. Because the food is self-sufficient, it is often fresh, raw and people often eat it hot. In addition, the way Eastern people dress and live is also very suitable for agricultural production. They use neat, convenient clothes, wear warm clothes in winter and cool clothes in summer. Most people in this area live in a certain location. It is usually a spacious and airy one-story house or a stilt house that is convenient in all aspects.
Not only associated with material cultural factors, the nature of rural agriculture is also expressed in folk beliefs and cultural activities. The two most common types of beliefs in the East are nature worship and fertility worship. It is very reasonable for Eastern people to worship nature because agricultural production, especially early agriculture, depends heavily on nature. If the weather is favorable, the harvest will be good, but if there is a natural disaster, most of the time there will be a total loss. That is why in all Eastern countries, people worship gods related to agricultural production such as the god
Earth, Rain God, River God, Wind God... Associated with nature worship are a series of agricultural festivals such as water-splashing festivals, harvest festivals, rain-praying festivals... In addition to nature worship, another popular belief is fertility worship. With the meaning of "fertility" - "many", "real" - "bloom", this belief expresses the desire to reproduce, maintain and develop life. In farming life, people want nothing more than good crops, abundant livestock, and many children, so people here have elevated fertility thinking to become an important belief of theirs.
In addition, the agricultural-rural character is also expressed through folk cultural activities such as singing, dancing, and musical performances. Forms such as antiphonal singing, lullabies, and nursery rhymes of Eastern countries, especially in Southeast Asian countries, all carry the rhythm of Eastern labor. That is the rhythm of agricultural labor such as plowing, harvesting, etc.
2.2.2. Eastern culture emphasizes community and emotional and flexible behavior in relationships between people.
Firstly, because the main production is agriculture. Production depends a lot on nature. On the other hand, the nature of the Eastern region is erratic, with many natural disasters, so to achieve high productivity, fight natural disasters, pests, etc., people must use the collective strength of the whole village and commune. This has formed a lifestyle that emphasizes community. This cultural trait has made each person think of the community and the collective when acting. And because of that, Eastern people often emphasize the obligations and responsibilities of the community and the collective.
Second, Eastern people mainly depend on each other and live in a communal spirit, so they treat each other very affectionately. Any problems that arise are resolved very flexibly. People live together with love, rely on each other, and help each other in times of difficulty and hardship. Therefore, behaving flexibly and valuing affection is one of the typical cultural traits of Eastern people.
2.2.3. Eastern culture is harmonious, follows nature, and utilizes nature to serve human life.
The attitude of harmony with nature in Eastern culture has been formed for a long time. In Eastern religions and in most traditional Eastern philosophical doctrines, people are not opposed to the natural world but are always considered an element, a part of the natural world. The reason is that agricultural production depends a lot on nature. If the weather is favorable, people will have a good harvest, but if there is a flood or natural disaster, they can lose everything. Therefore, in the hearts of the people, nature is always supreme, and they often have the idea of subduing rather than conquering nature.
In addition, Eastern people often take advantage of and exploit nature to serve their lives. Their material life has always been closely linked to nature. From daily activities such as eating, wearing, living to means of transportation, houses... they all exploit natural materials. That is why in the lifestyle, aesthetics and beliefs of Eastern people, nature has a great influence and occupies a very important position.
2.2.4. Eastern culture emphasizes traditional values and dislikes change:
First of all, Eastern culture emphasizes traditional values. The reason for this is because the life of Eastern people from ancient times has mainly relied on agriculture. All experiences in cultivation and animal husbandry were completely drawn from life by previous generations and passed down orally to the next generation. These are valuable achievements that when applied to actual production often bring success. That is why, from generation to generation, the thinking of Eastern people has been formed to respect and cherish traditional values.
Besides, the life of farmers needs stability. People are often afraid of unusual things happening. They want life to be peaceful, without disturbance. Therefore, a stereotyped lifestyle, afraid of change, has been formed in the Eastern people from generation to generation.
II. Theory of food consumption behavior
1. Basic theory of consumer behavior
1.1. Concept of consumer behavior
In the previous period, when the relationship between producers and consumers was tilted towards the producer, producers produced what they wanted and did not care much about the needs of consumers. However, in the current period, when the relationship between producers and consumers is tilted completely towards the consumer, producers will have to produce according to the needs of the market and specifically the needs of consumers. Therefore, a science has emerged to study consumer behavior with many different arguments, the basis of which is the concept of consumer behavior .
consumption . Specifically, in the book “Consumer Behavior and Related Issues” 8 , “Consumer behavior” is defined as “ the mental and physical activities of consumers and organizational customers in making decisions and carrying out the purchase, payment, and use of goods and services ”. Mental activities in this definition include determining the appropriateness of product or service categories, inferring the quality of products or services from advertising information, and evaluating actual experiences with products or services. Physical activities in consumer behavior include visiting stores, reading customer reports, talking to salespeople, and placing orders.
In addition, the American Marketing Association also provides a definition of consumer behavior. It is " the dynamic coordination of emotions and knowledge, behavior and environment by which people control the exchange between aspects of their lives" 9. This definition shows that consumer behavior is a coordination of thoughts, feelings, actions and environment.
around people. The word “dynamic” in this definition explains that the thoughts, feelings, and actions of individuals, groups, and societies are always changing. For example, the Internet has changed the way people search for information about products and services since its inception.
The above definitions all have their own views on consumer behavior, but in general, both of these definitions indicate that consumer behavior is first of all the mental and physical actions of customers. Second, those actions are aimed at making product choices.

Consumer behavior is made up of a series of four actions: choosing products and services, purchasing those products and services, using them and evaluating, and disposing of them after use. 10
10 Philip Kotler (2005), Marketing Essentials , Statistical Publishing House
1.2.1. Choosing products and services
The product choice process is a cognitive process for consumers. This process can be broken down into three steps as follows:
Identify needs:
In the first step, the consumer determines whether for some reason he is dissatisfied and wants to improve his situation. For example, internal drives, such as hunger or thirst, may tell the consumer that he needs food or drink. In addition to factors that arise internally, external factors can also trigger consumer needs (for example, advertising and marketing of new products by companies can trigger consumer needs and desires).
Search for information:
Once a consumer has identified their needs and wants, they will search for information about possible solutions. The sources used to obtain information may be simply information they remember from previous experiences (memory) or they may make a great effort to locate information from external sources (Internet searches, talking to others, etc.). How much effort a consumer puts into searching depends on factors such as: the importance of satisfying the need, familiarity with existing solutions, and the amount of time available to search.
Evaluation of options:
The consumer's search effort may result in a range of options from which the consumer can choose. In choosing a product, the consumer must go through two levels. At one level the consumer can make

- 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)
