- Organizing a management accounting system combined with financial accounting in the same apparatus: According to this model, accounting staff organize both financial accounting and management accounting in combination according to each accounting section. To collect information, management accounting uses the account system of financial accounting and opens details according to the information provision requirements, at the same time determining the content and recording methods on detailed accounts suitable for collecting, processing and providing specific information. Accounting books serving management accounting are the detailed book system of financial accounting. In addition, to meet management requirements, management accounting can design specific detailed books.
To implement this model, managers must understand the specific qualifications and capabilities of each accounting staff, and must clearly distinguish the work of financial accounting and management accounting in each section to serve the preparation of financial accounting reports and management accounting reports.
This model is often applied in small and medium-sized enterprises, with a low number of transactions. This model has the advantage of closely combining financial accounting and management accounting information, quickly collecting information, and saving costs. However, the limitation is that it is difficult to specialize two types of accounting according to modern technology.

- 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)

Organizing Capacity Training to Develop School Education Programs According to the New General Education Program for Management and Teaching Staff
- Organizing the management accounting system independently from financial accounting: According to this model, the department performing management accounting is independent from the department performing financial accounting. Based on the same initial voucher system, management accounting uses a separate account system and accounting book system from financial accounting. The accounts used in management accounting can use multi-level accounts and are classified, and recording methods are specified in accordance with the basic content of management accounting to create coordination in providing information for management. Management accounting makes estimates for each type of work for each department to prepare management reports.
This model is often applied in large-scale enterprises, with a large number of economic transactions, and multi-industry and multi-profession businesses. This model has

The advantage is that management accounting information is separated from financial accounting information, which is convenient for specialization and modernization. However, the limitation is that the information of the two subsystems cannot be generalized, which is time-consuming and costly compared to the combined model of financial accounting and management accounting because it requires additional steps of information circulation and processing and costs for the management accounting department.
- Mixed form (combining the two forms above): Organize a separate cost management accounting department, other content in a combined form.
Thus, each management accounting organization model has certain content, advantages and disadvantages, so the choice of which management accounting organization model needs to be based on factors such as: Type of accounting applied, type of business, scale and scope of business operations, characteristics of production and business organization, technological process and requirements, management level of the business...
1.3. Experience in organizing management accounting of some developed countries in the world and lessons learned for application to Vietnamese enterprises
1.3.1. Experience in organizing management accounting of some developed countries in the world
The information provided by management accounting is one of the important sources of information that helps managers operate, plan and make business decisions. To obtain this source of information, it is important that businesses organize management accounting according to an appropriate model. Management accounting has been formed and developed extremely rapidly in both theory and practice in the world, that process has created both common points and specific trends in each country. However, currently in the world there are 2 models of management accounting organization that businesses can consider, research and apply:
1.3.1.1. Management accounting organization model in the US
The United States is a country with a developed market economy, economic potential and an open market style of financial management. Management accounting in the United States is a management accounting system.
world pioneer in providing useful information, establishing management decisions using models and quantitative information techniques.
The management accounting system in the US is organized in combination with the financial accounting system in the same accounting system. The accounting system is not divided into a management accounting department and a financial accounting department, but is divided into accounting departments that perform accounting tasks according to assigned functions and tasks. These departments perform both financial accounting and management accounting work to satisfy and meet the information needs of both internal and external entities of the enterprise. Financial accounting uses a system of general accounts and general reports, while management accounting uses detailed accounts and departmental reports to collect and process information.
In the past, American accounting only focused on financial accounting, but today, when cost accounting and analysis play an important role in helping management make decisions, management accounting occupies an important position.
American management accounting also attaches importance to cost classification, especially cost classification according to cost behavior to analyze the Cost - Volume relationship.
- Profit to answer questions such as: What will the profit be at different levels of consumption? What level of consumption must be sold to achieve that particular profit level?
To account for production costs, accountants use two basic methods: job costing and process costing.
Performance evaluation and control in US management accounting focuses on short-term and long-term business decision making and financial statement analysis.
American management accountants view the budgeting process as important in capturing and reflecting the results of planning decisions, ranging from decisions about pricing, product mix, and cost structure to decisions about dividends and new investments.
Thus, American management accounting focuses on budgeting and setting specific short-term goals through the use of a diverse system of methods, including many methods from other sciences to quantify information, analyze, interpret and select investment projects and business production plans. In recent years, management accounting in American enterprises has undergone some changes in information structure, improving the qualitative nature of information and control to supplement shortcomings, backwardness and ineffectiveness compared to the world. Therefore, information from American management accounting is convincing and meets high management needs.
1.3.1.2. Management accounting organization model in France
The French Republic is a Western European country with a long-standing developed economy, with high-level economic management in general and accounting in particular.
The French accounting system consists of two parts: financial accounting (general accounting) and management accounting (analytical accounting). Management accounting in France is characterized by "static" accounting in financial accounting and dynamic accounting in management accounting. The management accounting system is organized into a separate apparatus (management accounting department or management accounting department) using a separate system of accounts, accounting books, and internal accounting reports that are relatively independent from financial accounting.
French management accounting places special emphasis on determining and controlling costs by dividing the enterprise into responsibility centers, analyzing, evaluating and finding the causes of cost deviations and finally harmonizing financial accounting and management accounting.
The objective of French management accounting is to calculate the costs of each center, the cost of each product and service, establish cost and result estimates, control implementation and explain the causes of differences between estimated costs and actual costs. The analysis of business results and assessment of factors affecting the business situation are carried out very carefully. Management accounting information is collected and processed through high-tech means through
Scientific calculation methods should ensure providing complete, accurate and timely information for managers to make correct business decisions.
1.3.2. Lessons learned and applied to Vietnamese enterprises
Studying the model of management accounting organization in some countries with developed economies will help us learn and acquire valuable experiences in the process of building and perfecting cost management accounting in Vietnamese enterprises in general and manufacturing enterprises in particular. Those lessons are:
- The management accounting system should be organized according to the American model, which means combining financial accounting and management accounting in the same accounting system to save costs and time in collecting, processing and providing information, suitable for the level of accounting staff of current Vietnamese enterprises, while ensuring convenience for management, inspection and control by the State.
- Management accounting should use financial accounting accounts but open details according to management requirements and departmental reports to collect, process and provide information in a timely manner to serve the process of making business decisions.
- Each accounting department should have clear and specific assignments and responsibilities to enhance the sense of responsibility in each individual's work, while avoiding overlap in the process of collecting, processing and providing information to business administrators.
- Production costs need to be classified clearly and completely, according to many different criteria to reflect and fully grasp all costs arising in the enterprise, identify the costs arising from there to help administrators manage costs closely.
- Applied research analyzes the relationship between costs, volume and profits to make decisions on the quantity of products to produce and consume, the structure of products consumed under the available conditions of the enterprise to achieve the level of
net profit as expected. From there, there is a basis for setting appropriate selling prices to meet market demand and maximize the potential of the business.
- Focus on building, consolidating and perfecting the system of technical economic norms and estimating the production and business process in a scientific and reasonable manner. Pay special attention to analyzing the operating results in relation to the costs incurred, finding the cause of any deviation, indicating the responsible department to have reasonable and timely adjustment solutions.
Learning valuable experiences from countries with developed economies will help us build, consolidate and perfect management accounting, especially cost management accounting in Vietnamese enterprises in general and manufacturing enterprises in particular in a scientific and effective manner, contributing to enhancing the position of Vietnamese enterprises in the process of international economic integration.
Conclusion of chapter 1: Chapter 1 has focused on researching and systematizing the basic theoretical issues of cost management accounting. First of all, this chapter presents and analyzes the concept and nature of management accounting in general, from which the concept and nature of cost management accounting are drawn. From there, it focuses on researching and clarifying the basic issues of cost management accounting regarding cost classification; Methods of determining production costs of products and services; Cost estimates in enterprises; Cost management accounting reporting system; Analysis of the relationship between costs, volume and profit; Cost management accounting organization models in enterprises. Based on the basic theory, this chapter studies the experience of organizing cost management accounting in some developed countries in the world to draw lessons and apply them to enterprises in Vietnam in a suitable and flexible manner to achieve the business's operational goals. The research issues in chapter 1 are the basis, premise, and guideline for studying and evaluating the current status of cost management accounting at Thai Nguyen Transport Construction Joint Stock Company I in order to propose solutions to improve cost management accounting at the Company.
CHAPTER 2
CURRENT STATE OF COST MANAGEMENT ACCOUNTING AT THAI NGUYEN TRAFFIC CONSTRUCTION JOINT STOCK COMPANY I
2.1. Overview of Thai Nguyen Traffic Construction Joint Stock Company I
2.1.1. The formation and development process of Thai Nguyen Traffic Construction Joint Stock Company I
Thai Nguyen I-Transportation Construction Joint Stock Company, formerly Thai Nguyen I-Transportation Construction Company, is a state-owned enterprise under the Thai Nguyen Department of Transport, established on January 1, 1976 with the name "Bac Thai Road Construction Company" according to Decision No. 256/QD-UB of the People's Committee of Bac Thai province.
But to meet the requirements of production and business, on February 2, 1982, the company was renamed "Bac Thai Road Construction Enterprise" according to Decision No. 13/QD-UB of the People's Committee of Bac Thai province. Based on the 1986 classification criteria, the enterprise was classified by Bac Thai province as a Grade 2 Enterprise according to Decision No. 125/QD-UB dated September 13, 1986 of the People's Committee of Bac Thai province. At that time, the annual task of the Enterprise was: To build new and upgrade road surfaces of all kinds (including horizontal and vertical drainage systems and small-span wooden bridges) on roads within Bac Thai province.
In order to develop a socialist-oriented market economy, implement the policy of the leading role of State-owned enterprises in the national economy, and at the same time, based on the actual situation and conditions of the Enterprise and Bac Thai province, on November 28, 1992, according to Decision No. 607/UB-QD of the People's Committee of Bac Thai province (now Thai Nguyen province), "Bac Thai Road Construction Enterprise" was established and renamed "Thai Nguyen Traffic Construction Company I". This is a State-owned enterprise, a full legal entity, with its headquarters located at Group 15, Tan Thinh Ward - Thai Nguyen City - Thai Nguyen Province.
Implementing the Government's policy of innovation and restructuring of State-owned enterprises, Thai Nguyen Traffic Construction Company I was approved by the Thai Nguyen Provincial People's Committee for equitization plan according to Decision No. 3317/QD-UB dated December 17, 2003 and was renamed Thai Nguyen Traffic Construction Joint Stock Company I. Thai Nguyen Traffic Construction Joint Stock Company I started operating from January 2004. Business registration certificate No. 17030000072 issued by the Department of Planning and Investment of Thai Nguyen province on January 1, 2004; first change registration on January 2, 2004, second change registration on August 5, 2008.
Thai Nguyen Transport Construction Joint Stock Company I was established from the equitization of a state-owned enterprise in the form of selling a part of the state capital in the enterprise, issuing additional capital with the aim of expanding the scope and scale of production and business activities on the basis of voluntary capital contribution of shareholders including all officers and employees of the company and other shareholders outside the company. The total charter capital of the company is 5 billion VND, of which the state capital accounts for 30% and the charter capital is divided into 50,000 shares.
The company's business lines are as follows:
- Construction of works: Traffic, civil, industrial, irrigation, site clearance.
- Exploitation, processing and trading of construction materials for transportation and construction projects.
- Production of precast concrete components.
- Buying and selling of transportation equipment and materials.
- Construction of civil and industrial electricity.

- 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)
