- 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)

The results of the next survey showed that up to 68.5% of respondents recognized that people's needs and aspirations were decisive factors in planning activities to build new rural areas. Thus, people felt their role in planning activities to build new rural areas.
However, we see that the percentage of people who think that the opinions of the authorities at all levels are the deciding factor is up to 31.5%. This situation partly reflects the reality of the new rural construction taking place in the communes of Quy Nhon city, where most people understand and have the need to contribute their opinions and wishes in the new rural construction, but still always expect the government to participate in planning for all local activities.

Figure 4.8 Survey ratio of decisive factors for planning for new rural construction activities
One good thing is that through the survey, up to 54.9% of the people interviewed were invited to attend meetings to discuss and give opinions on issues related to the construction of the new rural areas. This shows that the local government has been very active in creating conditions for discussion with the people and actively receiving reasonable contributions from the people in the construction of the new rural areas. However, besides that, 35.4% of the people were not invited to attend the meetings and 9.7% of the people were not interested in this. The main reason for the problem is that up to 52.6% of the people interviewed said that they did not have time. Through in-depth interviews, it was shown that, with the characteristics of the people in island and peninsula communes, the man who is the head of the household often goes to work at sea and is away from home at night, so he does not have the conditions to attend meetings to discuss issues related to the construction of the new rural areas. This is also something that the commune-level government needs to pay attention to in order to have a method.
and the time for consultation with people in coastal communes is more appropriate, creating conditions for people to contribute their opinions and wishes.

Figure 4.9 Percentage of people invited to participate in activities related to new rural construction.
Through interviews with a number of households, it is shown that the participation of people from the beginning in planning, making projects to build new rural areas or collecting community opinions for new rural planning is carried out quite well by the commune authorities, but when it comes to collecting people's opinions on which projects should be built first, the level of people's financial and material contributions to the construction of local projects, etc., the localities have not paid much attention.
A noteworthy figure is that 16.8% of respondents said that they were not interested in participating in planning for rural development in their locality. In addition to the reasons mentioned above, there is another subjective reason that local people are only interested in jobs, benefits or public services.
The construction process is directly and practically related to their daily lives, while the work that they describe as being at the "macro" level, of a technical and professional nature, must be the responsibility of the local government, and the people cannot participate. With this shallow awareness of the people, the local government must see more clearly its responsibility to have more appropriate solutions and methods, so that in the short term as well as in the long term, the construction of the new rural area in the locality must truly have the participation and contribution of the people, the participation and ownership role of the rural community in the process of building the new rural area is one of the most important factors to ensure sustainable rural development.
Thus, in participating in discussions and opinions in building new rural areas, there is still a large number of people who do not fully perceive their role, always waiting for the local government to plan activities to build new rural areas in the locality, they are only interested in jobs, benefits or construction works that are directly and practically related to their daily lives. Activities according to regulations that require the participation of the people such as: which works should be built first; the level of money and material contributions of the people for the construction of local works, ... are rarely consulted by the government with the people's opinions, the people mostly only know when starting construction or bringing it to people's meetings, when it is necessary to call for contributions. The level of people's participation according to the scale of "knowing, discussing, doing, checking" tends to decrease gradually. Only activities directly related to people's lives and when it is necessary to contribute costs to build works directly related to the community will have people's participation.
4.2.4 People directly participate in building new rural areas
According to the report of Quy Nhon City People's Committee, the total investment capital for new rural construction in the past 5 years in the city in the period of 2011 - 2015 was 156,633 million VND, of which people's contribution was 17,348 million VND, accounting for 11.1%. ( Summary report of 5 years of implementing the National Target Program on new rural construction in the period of
2011-2015 period, and implementation of tasks for the period 2016-2020, Quy Nhon City People's Committee, 2016 ) If we include the contribution of the people such as: donated land area of 76,282 m2 , participation in over 8,200 working days in local construction projects, self-investment in the process of production development, self-renovation and repair of fences, gates, toilets, ... then it can be said that the contribution of the people when participating in the construction of the new rural area accounts for a very important part.
The forms of people's contributions are also very diverse, from contributing money, donating land to working days. 42.6% of households participated in contributing working days, 25.4% of households donated land, 15.6% of households contributed money, and 9.8% of households participated in kind. This is completely understandable, because people in rural areas with low incomes have limited financial contributions. On the other hand, these are purely agricultural and purely fishing communes with the majority of workers working in agriculture and fishing, so participating in working days will be suitable for the ability to build common works in the locality.

Figure 4.10 Forms of people's contributions
* Some typical models of direct participation of people: Rural road construction model
One of the infrastructure projects in the 4 surveyed communes that the government and people are interested in and choose to prioritize is the asphalting and concrete of traffic routes. This is of great interest to the people and they enthusiastically participate in meetings organized by the commune when collecting community opinions on the construction of local traffic routes. After 5 years of implementation, the 4 communes building new rural areas of Quy Nhon city have built 21.41 km of commune roads, 26.27 km of village roads, 30.81 km of alley roads, 10.93 km of intra-field roads, the traffic system to the commune People's Committee headquarters and the main roads of the commune, village, and hamlet have been built and basically completed, creating favorable conditions for people to travel and live. As of December 2015, all 4 communes met the traffic criteria.
In the construction of rural roads, the commune authorities have mobilized the people's strength from donating land to build rural roads. According to the report of Quy Nhon City People's Committee, 476 households have donated land to build rural roads and some social security works with a total area of 76,282 m2 , worth more than 1,947 million VND (according to state prices). (Summary report of 5 years of implementing the National Target Program on New Rural Construction in the period of 2011-2015, and deploying tasks in the period of 2016-2020).
A remarkable success worth noting about the good way of doing things of the commune authorities is that they mobilized the entire political system to participate in propaganda and mobilizing people to participate in building roads. The communes organized meetings to get people's opinions on which road sections needed to be constructed first, how much the road was widened, how people would participate and contribute, reminding each other to dismantle fences themselves, participate in the construction process, etc. Therefore, the cost of compensation and site clearance before construction was insignificant, people voluntarily dismantled fences, cleaned up
trees, architectural objects to hand over the site, participate in the labor day, create the best conditions for the construction unit. After completion, some main roads were assigned to the commune-level associations in charge in the form of "Self-managed roads", coordinating with the branches in the villages to regularly carry out the work of weeding the roadside, maintaining hygiene, and handling and patching small damages. Therefore, up to now, when asking the opinions of people in the 04 communes, the most satisfied with the implementation of the new rural construction program is the construction of rural roads.
Hybrid rice production model
Among the criteria for evaluating NTM, the income criterion is one of the criteria that authorities at all levels pay close attention to and direct. From the beginning, the province has had a policy of implementing the transformation of crop structure, economic restructuring, based on the characteristics and advantages of each locality to form large-scale specialized areas, promulgating policies to support seed prices, preferential loans, technical support, etc. Thanks to that, many localities have proactively applied it in practice, taking advantage of the support of specialized agencies, businesses and especially the proactiveness of the people, so the income criterion has been achieved early in the localities.
One of the programs that is considered successful and contributes to changing the face of the countryside is the hybrid rice production program implemented in Phuoc My commune. Since the beginning of the New Rural Development Program, the hybrid rice production program has received attention and direction from authorities at all levels. This is considered one of the solutions to transform the crop structure to intensify farming, increase productivity and rice output, in order to increase the income value per hectare of cultivation, and increase income for local people.
However, when it was first implemented in localities, the program encountered resistance from many farmers for the following reasons: people had no experience in producing hybrid rice; the amount of hybrid rice seeds when sown was too little, only 2 - 2.5 kg/sao (500m2 ) while pure rice had been sown for a long time at 6 - 8 kg/sao, how could there be enough seeds to sow, if
affected by floods, rats eat and there is no rice to harvest; hybrid rice production requires additional investment in fertilizers, pesticides, care, high costs, etc.
To make people believe in the program, the Economic Department and the City Agricultural Extension Station discussed and agreed with Phuoc My commune to select about 2-4 sao of rice fields in each village and to choose the field owners who must be advanced and active to build demonstration models of hybrid rice production. Technical staff of the Economic Department and the City Agricultural Extension Station went down to the villages and hamlets to increase technical support for the field owners, organize direct guidance and instruction in a "hands-on" manner for the field owners to carry out the stages in the production process. The results of the demonstration models were successful beyond expectations: the average hybrid rice yield reached 72-78 quintals/ha (previously pure rice in the commune only reached 45-50 quintals/ha), rice was less susceptible to pests and diseases, the cost of buying fertilizer and pesticides was not much higher than pure rice production, hybrid rice tasted better, the selling price of hybrid rice was 600-800 VND/kg higher than pure rice depending on the time, ...
From the initial results of the demonstration models, the local government coordinated with specialized agencies to organize field workshops right at the model owners' fields, inviting all farmers in the production area to visit the field and evaluate the results of hybrid rice production. A good way is that the person reporting the results and the implementation process of the model is the field owner who directly produces hybrid rice, not the technical staff. The questions of the people were explained clearly and easily by the field owner, so the farmers who came to visit were truly convinced of the advantages of hybrid rice varieties. At the field workshop and at the village and hamlet meetings later when discussing the expansion of hybrid rice production, the people who had visited the field and the owners of the model fields stood up and expressed their high consensus on applying hybrid rice production, explaining to other farmers when they disagreed with the program, and most of the meetings ended with the result that the majority of people decided to apply hybrid rice production in the next crop.

- 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)
