- 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 Research Results of the Thesis Are Consistent with the Stated Scientific Hypothesis, and the Tasks of the Topic Have Been Solved.
There are many foreign studies related to the quality of vocational training, but they mainly focus on issues of reforming the vocational training system and improving the quality of human resources to solve the problem of labor supply of the country's technical workers in the period of industrialization and modernization of the country. Typical research works include the following:
- The report: "Reforming Education and Vocational Training" of the World Bank, has summarized the experiences of countries divided into different groups, such as underdeveloped countries, developed countries and transition countries. The report has made proposals in solving the problem of reforming the current vocational education system to suit the needs of the labor market. Training what the market needs, the quality of vocational training must be suitable to the technological development of each country. Each country, each economy has different specific conditions, so there are different lessons on reforming the vocational training system. In particular, the report mentions different policies and models of economies in solving the relationship between training and the labor market.

- Asian Development Bank (ADB) with the report "Technical Education and Vocational Training" in 1990; The report pointed out the functions and characteristics of the vocational training system, the policies of countries in vocational training. Pointed out that vocational training meets the needs of different economic sectors in the economy; a point
The importance of this Report is that it has gone into depth in analyzing the structure of the education and vocational training system with the experience of many countries with different vocational training models.
- Donal L. Kirkpatrick (1998) researched and proposed a "Model of training program evaluation with 4 levels", with basic arguments and theories on evaluating the quality of training programs with 4 levels of learners.
Based on the development of Kirppatrick's evaluation method, the author conducted a survey to evaluate the training quality of Industrial Electricity Engineering at Vietnam Electricity Group.
4.2. Some domestic studies
- Le Khac Doa's doctoral thesis (1989) on "Improving the vocational training system in Vietnam" studied and proposed to improve the vocational training system in Vietnam. The author believes that it is necessary to have a standardized vocational training system with a unified organizational model and operating regulations in order to improve the quality of vocational training in Vietnam.
- Associate Professor, Dr. Pham Thi Thanh chaired the ministerial-level project "Research on training university lecturers and vocational teachers" which pointed out the weaknesses and shortcomings in pedagogical methods in teacher training and development in the 90s of the last century;
- Engineer Ta Sy Thai (2000) with "Standardizing the training program for electrical engineers", focused on solving the problem of orientation for building a long-term 2-year training framework program for electrical engineers.
- Associate Professor, Dr. Thai Ba Can (2004) with the research "Proposing a method to evaluate training quality with internal effectiveness evaluation (evaluation of degrees, score results); and external effectiveness evaluation (time in employment, career success)", has put forward the viewpoint that the evaluation of the training quality of the School is not only based on training degrees, but also must be based on the results of whether or not the trained workers can find a job suitable for the profession they have been trained in.
- Doctoral thesis of Tran Khac Hoan (2006) on "Combining training at school and enterprises to improve the quality of vocational training in Vietnam in the current period". The author believes that there needs to be a connection between schools and enterprises in vocational training, helping to interact and support each other in training between theoretical teaching and practice.
- Dang Ngoc Lam (2007) with the work: "Research on building standards for CNKT ranks of occupations in power companies under EVN", has provided specific regulations on responsibilities, knowledge, and qualifications for CNKT of occupations. This set of standards has helped the human resource management levels of the Group have a basis to compare standards in meeting the necessary and sufficient conditions for each worker title, thereby having orientation for studying, practicing and improving professional qualifications as well as skills.
- Resolution No. 27-NQ/TW (2008) of the 7th Conference of the Party Central Committee (10th tenure) on "Building a contingent of intellectuals in the period of promoting industrialization and modernization of the country" mentioned the concretization and effective implementation of the Party and State's policies on education and training innovation; focusing on innovation of program content, teaching methods, improving the quality and efficiency of all levels of education; especially attaching importance to vocational training associated with the needs of learners and social needs.
- The Ministry-level project of the General Department of Vocational Training according to Decision No. 192/QD-TCDN, dated September 25, 2009, "Research and proposal to build a framework program for College and Secondary level". This is a project that has standardized the framework programs for long-term training of technical and vocational staff (2 years of intermediate level, 3 years of college level).
- Bui Ton Hien (2009) with the research results "Employment of workers through vocational training in Vietnam", pointed out that the employment factor after training has a great impact on the quality of vocational training.
- Le Quang Son (2009) with the research "Experiences of the United States, China, Singapore, and Japan on vocational training policies, including training
"creating CNKT" has pointed out the importance of the state's macro policies on vocational training.
When researching on training and developing human resources and technical staff at Vietnam Electricity Group; the author had the opportunity to access and research a number of specific scientific topics at the Group level:
- The latest is the Project: "Training and human resource development plan of Vietnam Electricity Group for the period 2008-2010, expected to 2015". This project has proposed solutions and orientations for building a human resource plan for the entire staff of the Electricity industry.
Thus, although there have been studies on technical worker training, have pointed out factors affecting vocational training for technical workers, have proposed and implemented tasks to improve technical worker training, such as building a framework program for vocational training; pointing out the importance of unifying the organizational model in the management of vocational education and training system and employment for workers; pointing out methods to improve the quality of teaching staff and vocational training... but there has not been any study that systematically and specifically examines the quality of technical worker training in a specific industry, especially the Electricity industry of Vietnam.
From the above research results, combined with the practical work and scientific research of the Vietnam Electricity industry, the author realized that it is necessary to have a research project to objectively and comprehensively evaluate the quality of technical training of the Vietnam Electricity industry, through specific studies of the situation of EVN, on the basis of scientific arguments to clearly see the factors affecting the quality of technical training of the Vietnam Electricity industry; thereby proposing solutions to improve the quality of technical training of the Vietnam Electricity industry to meet the requirements of the tasks in the new situation.
These are the contents that need to be further seriously studied, in order to improve the training and development of human resources in the electricity industry of Vietnam.
5. Research subjects
The thesis mainly focuses on studying the quality of training of industrial electricity technicians at some vocational training schools and some vocational training programs in the corporations of Vietnam Electricity Group.
6. Research methods
6.1. Methodological basis
Training is a process of converting inputs into outputs. The training cycle can be illustrated in the figure below:

- New knowledge, skills and attitudes
- Changing behavior at work
- Work results
- Impact on the organization
The output of training reflects the quality of the training program. From the current state of EVN's technical training, it is necessary to evaluate the training results in a practical way, through measurable criteria that directly serve the work of the trainees.
The thesis uses the training program quality assessment model proposed by Kirkpatrick. It can be briefly described as follows:
Level 1. Reaction
Level 1 measures learner satisfaction with the training program, the measurement criteria are usually content, lecturers, and learning activities. Level 1 assessment is usually conducted at the end of the training program with a survey or interview.
Level 2. Learning
Level 2 measures the knowledge, skills, and attitudes that learners have acquired through the training program. Level 2 assessment criteria focus on learners’ retention of what has been learned in the program. Level 2 assessments are typically surveys, tests, or interviews conducted at the end of the training.
Level 3. Behavior
The goal of level 3 assessment is to measure changes in work behavior after trainees have been trained. In other words, level 3 provides some indicators showing which knowledge, skills and attitudes the trainees have applied in the course to their actual work and improved the quality of their work. Level 3 assessment is much more difficult than the previous 2 levels, because in reality, the working environment/conditions are important factors influencing the application of knowledge/skills/attitudes that trainees have acquired in their actual work. To most accurately assess level 3, it is necessary to expand the assessment objects, not only including trained trainees, but also related people such as direct managers of the trainees. Comparison of work results before and after training also needs to be done to clarify the level of influence of the training program on changes in trainees' work results.
Level 4. Results
The goal of level 4 evaluation is to measure the impact of the training program on the trainees’ organization. Level 4 measurement involves assessing the organization’s capabilities before and after the training program. It is difficult to accurately assess level 4 because organizational effectiveness depends on many factors that are difficult to separate. Therefore, level 4 evaluation is usually conducted only in the form of interviews with the organization’s management and measures qualitative criteria about the organizational change that resulted from the trainees participating in the training program.
6.2. The thesis uses the following research methods:
- Statistical methods, document review, inheriting domestic and foreign research results related to research content.
- Practical survey method, in-depth interview to evaluate unclear issues while using questionnaire.
- Methods of generalization, induction, interpolation, comparison... and quantitative calculations.
7. Contribution of the thesis
7.1. About theory
From the general theory of training quality, the thesis has presented a viewpoint on the quality of training of technical workers (CNKT) in the Electricity industry and pointed out the criteria reflecting the quality of CNKT meeting the requirements of the Electricity industry, specifically: (1) Through standard training from the Electricity industry vocational training school, having professional knowledge and skills that meet the standards of workers. (2) Industrial style; absolutely comply with labor discipline, strict procedures and regulations of the Electricity industry. (3) Have good health, meet the requirements of the specific working environment of the Electricity industry. (4) Understand and implement corporate traditions and culture; ethics, healthy lifestyle. (5) Have the ability to adapt, work independently and coordinate with teammates in labor.
The thesis has introduced some quantitative models for assessing training quality and pointed out the use of Donald L. Kirkpatrick model to propose a model for assessing training program quality, which is to assess the training cycle from input quality to output results and post-training effectiveness. Using the training quality assessment model according to the cycle is to model the relationships between variables reflecting the quality of training and factors affecting the quality of training, measuring and assessing the level of influence of those factors on the quality of training.
7.2. In practice
The study has shown that the characteristics of the electricity industry affect the quality of CNKT training and the factors that ensure the quality of CNKT training.
Electricity includes: (1) Training goals and strategies linked to the development goals of enterprises, industries, society and international integration. (2) Appropriate and synchronous training management model with a combination between enterprises and schools in training, especially from the vocational training stage. (3) Institutionalizing the training of technical workers. (4) Standardizing the team of leaders, training managers, lecturers and practice instructors. (5) Appropriate investment and financial investment attraction mechanisms , with the participation of 3 parties: State - Enterprises - Schools. Encouraging socialization to attract economic sectors and resources to participate in technical labor training.
Combining practical analysis and research on technical worker training in some countries to improve the quality of technical worker training to meet the requirements of the country's industrialization and modernization, including the Electricity industry, the thesis recommends a number of solutions to contribute to improving the quality of technical worker training not only for the Electricity industry, but also for other industries.

- 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)
