Regarding the salary and bonus mechanism, the salary of employees and officials is increasing, but is still low. Official employees have received profit sharing from the management board, so their salary has been improved. Many workers, especially seasonal workers, do not have social insurance and have low salaries. Hapro's average income per capita in 2007 increased by 45% compared to 2006, the average technical labor force reached 2.8 million VND, and the salary of simple laborers reached 1.5 million VND.
2.2. Current status of goods and supply chain management
Managing goods and supply is a very important part of retail management, especially when goods in supermarket systems or convenience stores are extremely diverse, so management is extremely difficult and complicated.
Goods management and supply chain management include the organization of goods sourcing, storage and distribution.

- 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)

Results of the Impact of Factors on the Efficiency of Public Investment Management in Tien Giang
The organization of goods sources has been focused on by businesses to have a rich and diverse source of goods, ensuring quality and reasonable prices.
The sources of goods of retail systems today include both domestic and imported goods, not just imported goods as before. Enterprises often buy domestic goods directly from reputable domestic manufacturers, while imported goods are purchased from official distributors of foreign brands. Imported goods are often wines, foods, beverages, and household electronics. The types of goods commonly sold by supermarkets and stores are:

- Processed food: sugar, milk, cakes, candy, tea, coffee, cooking oil...
- Processed foods: canned foods, ham, sausages...
- Processed foods: instant noodles, pasta, spaghetti...
- Cosmetics: detergents, cosmetics
- Household items made of aluminum, plastic, stainless steel, glass, ceramic
- Garment
- Frozen food products
- Fresh food products
The structure of goods in supermarkets today is as follows:
- Food: 30-35%
- Household appliances: 30%
- Cosmetics: 20-25%
- Fresh food: 5-10%
- Domestic product ratio: over 70%
In general, with the above commodity structure, supermarkets and retail stores have relatively met customers' needs, however, the proportion of fresh food is still too low compared to consumer demand.
Retail businesses typically purchase goods from suppliers in the following ways:
Free purchase: This is a flexible purchasing method based on the supplier and the business agreeing on quantity, quality, and price. This method is applied to goods that can be preserved for a long time (clothes, household items, etc.), and the design and quality are often not according to any specific standards, but depend on the agreement of both parties.
Become a sales agent for the manufacturer: The distributor signs a contract to become a retail distribution agent for the manufacturer and receives a commission based on a percentage of sales revenue. This form is beneficial for the distribution business, because it does not have to invest capital to buy goods and does not worry about loss of profit when the goods are not consumed. The types of products purchased in this form are ready-to-use processed foods such as: milk, canned food, meat, frozen seafood, fresh vegetables and fruits, ham, sausages, vegetables, pickles, etc.
Contract purchasing: Stores sign long-term purchasing contracts with suppliers, helping to stabilize the source of goods and save on inventory costs.
storage. Businesses that can apply this form often have large working capital and reputation. [2]
However, in retail businesses, there is still a lack of initiative from purchasing, inspection, preliminary processing, packaging to selling to the market. While these stages all play a very important role in the supply chain, contributing to ensuring that goods are always fully available at the booth, while ensuring quality.
Many distribution businesses are currently not proactive in linking with manufacturers to ensure supply. The purchase of goods is still sporadic due to the lack of long-term commitment with manufacturers and no forms of goods insurance, so there are often phenomena of manufacturers canceling supply contracts when the market shows signs of fluctuation. Furthermore, domestic distributors sometimes cause discomfort to manufacturers because of the ambiguity in setting standards for goods. Meanwhile, this work is done very carefully and clearly for foreign distributors, making suppliers feel more secure when doing business with foreign businesses. The director of a textile enterprise said: When offering goods at Metro, the purchasing department here presents all the industry standards, designs, colors, sizes, percentages for marketing and advertising, terms of support for buyers and requirements for suppliers... All are computerized, updated and presented clearly and transparently for suppliers to refer to. Meanwhile, when working with Vietnamese supermarkets, the negotiation process is very sketchy, and Vietnamese enterprises refuse to sell their goods. This makes suppliers unconvinced. This phenomenon shows that Vietnamese retailers have not yet determined the long-term direction for their goods sources, and has also reduced their competitive advantage compared to foreign enterprises.
Besides the problem of goods sources, the preservation and distribution of goods of Vietnamese enterprises still have many shortcomings, due to the work of
Logistics such as warehouses, cold storage, yards, and infrastructure systems are still too few and rudimentary. Specialized trucks have not yet met regional and international standards, and some businesses still have to transport goods by rudimentary motorbikes due to the narrow and congested roads in Vietnam. By June 2006, the whole country had only 239,470 trucks (equivalent to 37.9% of the number of cars), of which there were 58,458 specialized vehicles (accounting for 9.2% of the number of cars). This number of specialized vehicles only met 53% of the volume of goods transported and 10% of the volume of goods circulated. The number of trucks with a load capacity of 3 tons accounted for only 16%, the load capacity of 2-7 tons accounted for 13.2%, and over 7 tons accounted for 8.6% [3]. Furthermore, the coordination of delivery vehicles to the right type, right place, right time is still managed quite simply in distribution enterprises, greatly affecting business operations. Such supply conditions cause many difficulties in goods management, difficulty in ensuring quality, high circulation costs, thus leading to high product prices.
An example of the failure of Vietnamese businesses due to poor supply chain organization is the case of G7 Mart. The G7 Mart convenience store chain was established in 2001, and was carefully prepared to combine distribution optimization between diverse store systems, closely linked to consumers, extensive PR activities, combining modern business management and traditional distribution characteristics. However, the business of this system still failed due to poor supply chain organization, failure to negotiate the source of goods, types, prices, discounts, and failure to obtain the best and most reasonable supply price, thus unable to control profits. Therefore, this chain of stores had to close after nearly a year of operation.
To better connect with suppliers as well as ensure the quality of goods management, in addition to strengthening business links with manufacturers as mentioned in the Current status of operations section, supermarkets and stores also increase the application of high technology to better manage imported goods, the quantity of goods available in the store, the quantity of goods sold.
are sold. The commonly used technologies are barcode technology, software with specific functions such as accounting, cash register, etc. Currently, Saigon Coop and G7 Mart have both signed contracts with Microsoft to use modern management software in business management. G7 Mart has used the Microsoft Dynamic (GMS) retail solution. The Hapro system is implementing the e-Hapro electronics corporation project, with the aim of connecting with manufacturers and customers online. The construction work includes the use of supply chain management software systems (SCM), building e-portal information portals, etc. However, the rate of enterprises using information technology in our country is still very limited and rudimentary, mainly stopping at using accounting software, websites, without knowing how to exploit the deeper advantages of information technology in management work.
2.3. Current status of customer management
Customers coming to modern retail systems today are not only middle class as before, but often customers with average income or higher, mostly workers, civil servants, students. The number of customers coming to supermarkets to shop weekly is about 700 to 800 for small supermarkets, and up to several thousand/week for large supermarkets. This number during holidays and Tet holidays can increase to 3000-4000/day.
Customer management is also quite complicated due to the large number of customers. As mentioned in chapter 1, the function of customer management is to collect customer information, including potential customers, long-term customers, and old customers, from which to establish necessary customer care regimes. The purpose of this work is to better meet the needs of customers.
Currently, customer management of supermarkets and shopping centers is still unprofessional, due to difficulties in collecting customer information. Many businesses do not know which customer group brings them the most profit. Some businesses also
Retailers often only pay attention to analyzing data and customer transaction figures, but do not really care about attracting and gaining good feelings from customers during and after purchasing. This leads to a situation where retailers lack information about customer feelings, hindering the improvement of product quality and store services. Therefore, businesses can hardly have long-term customers.
Some businesses like Hapro have thought about applying CRM (Customer relation management) software. However, to make good use of this solution, businesses still need to have a detailed plan to collect customer information, to have enough data for the software to be effective and to create reasonable customer care plans. Many businesses have not clearly defined the purpose of using this software, so they do not get the expected benefits, leading to ineffective investment.
2.4. Current status of brand management
Becoming a retail business with a good brand in the hearts of customers is always the goal of retailers, and this is also the most effective way to attract customers.
Currently, the strongest branded retail businesses in Vietnam are Metro, Big C, Fivimart and Intimex in Hanoi, Coopmart, Mien Dong supermarket in Ho Chi Minh City. These supermarkets attract many customers based on rich and complete sources of goods, beautiful displays, reasonable prices, good service quality, and attentive staff. Businesses today increasingly realize that brand development must be based on the totality of factors, not just depending on advertising and marketing.
Advertising and marketing activities are always focused on by businesses. The Hapromart chain of stores has just completed its brand identity with a green background logo, and is also developing its chain of stores on the
that green background. All supermarkets have various forms of promotion, such as discounts, loyalty cards, customer clubs…
3. General comments
3.1. Results of retail management in Vietnamese enterprises
Through analysis of the current management situation, it can be seen that retail management in our country has had the following initial results:
The human resource organization structure is increasingly effective, the salary of staff is increasingly improved, and the working conditions of staff are improved.
Supply chain organization is increasingly focused on and is being upgraded. Many businesses are applying high technology to this management work.
Customer management is taken more seriously, customer needs are better met.
Businesses have realized the importance of brand management based on improving the management quality of all stages of retail management.
3.2. Weaknesses in retail management
Unprofessional retail workforce, due to lack of training and ineffective labor utilization.
The organization and management of goods and the supply chain are not up to standard.
Unprofessional customer management, not fully meeting customer needs.
Most brand management work still focuses on investing in advertising and marketing, without really improving the image of the modern retail system in the eyes of customers.
3.3. Weak causes
The main causes of weaknesses in retail management are mainly due to the following reasons:
- Modern retail distribution activities are still quite new in our country, so the infrastructure is still weak, distributors have not really found solutions in developing infrastructure.
- Training for human resources is limited, knowledge of modern retail management is not widely known in Vietnam. Managers lack experience in business planning and decision making.
- Lack of capital is always an important problem for Vietnamese retailers today in upgrading logistics and technical equipment in sales.
Besides the micro-level causes, there are also some macro-level causes such as:
- The State has not really had a specific plan for the retail system nationwide and in each locality, so the system still operates in a fragmented and spontaneous manner.
- The law relating to retail system business has not been passed by the National Assembly.
- Regulations promoting the retail system business of domestic enterprises have not received attention from the State.
The above reasons are really big barriers for domestic enterprises in the current fierce competition with foreign retail giants.

- 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)
