of the islanders. Therefore, this indicator will be divided into two sub-indicators:
a1. Natural tourism attractiveness a2. Cultural tourism attractiveness
b. Tourist capacity
The two island communes in Quan Lan have different capacities to receive tourists. Minh Chau Commune is home to many standard hotels and resorts, attracting high-income domestic and international tourists. Meanwhile, Quan Lan Commune has many motels mainly built and operated by local people, so the scale and quality are not high, and will be suitable for ordinary tourists such as students.
c. Time of exploitation of Quan Lan Island Commune:
Quan Lan tourism is seasonal due to weather and climate conditions and festivals only take place on certain days of the year, specifically in spring. In Quan Lan commune, the period from April to June and from September to November is considered the best time to visit Quan Lan because the cultural tourism activities are mainly associated with festivals taking place during this time.
Minh Chau island commune:
Tourism exploitation time is all year round, because this is a place with a number of tourist attractions with diverse ecosystems such as Bai Tu Long National Park Research Center, Tram forest, Turtle Laying Beach, so besides coming to the beach for tourism and vacation in the summer, Minh Chau will attract research groups to come for tourism combined with research at other times of the year.
d. Sustainability
The sustainability of ecotourism sites in Quan Lan and Minh Chau communes depends on the sensitivity of the ecosystems to climate changes.
landscape. In general, these tourist destinations have a fairly high level of sustainability, because they are natural ecosystems, planned and protected. However, if a large number of tourists gather at certain times, it can exceed the carrying capacity and affect the sustainability of the environment (polluted beaches, damaged trees, animals moving away from their habitats, etc.), then the sustainability of the above ecosystems (natural ecosystems, human ecosystems) will also be affected and become less sustainable.
e. Location and accessibility
Both island communes have ports to take tourists to visit from Van Don wharf:
- Quan Lan – Van Don traffic route:
Phuc Thinh – Viet Anh high-speed boat and Quang Minh high-speed boat, depart at 8am and 2pm from Van Don to Quan Lan, and at 7am and 1pm from Quan Lan to Van Don. There are also wooden boats departing at 7am and 1pm.
- Van Don - Minh Chau traffic route:
Chung Huong high-speed train, Minh Chau train, morning 7:30 and afternoon 13:30 from Van Don to Minh Chau, morning 6:30 and afternoon 13:00 from Minh Chau to Van Don.
f. Infrastructure
Despite receiving investment attention, the issue of infrastructure and technical facilities for tourism on Quan Lan Island is still an issue that needs to be resolved because it has a direct impact on the implementation of ecotourism activities. The minimum conditions for serving tourists such as accommodation, electricity, water, communication, especially medical services, and security work need to be given top priority. Ecotourism spots in Minh Chau commune are assessed to have better infrastructure and technical facilities for tourism because there are quite complete and synchronous conditions for serving tourists, meeting many needs of domestic and foreign tourists.
3.2.1.4. Determine assessment levels and assessment scales
Corresponding to the levels of each criterion, the index is the score of those levels in the order of 4, 3, 2, 1 decreasing according to the standard of each level: very attractive (4), attractive (3), average (2), less attractive (1).
3.2.1.5. Determining the coefficients of the criteria
For the assessment of DLST in the two communes of Quan Lan and Minh Chau islands, the students added evaluation coefficients to show the importance of the criteria and indicators as follows:
Coefficient 3 with criteria: Attractiveness, Exploitation time. These are the 2 most important criteria for attracting tourists to tourism in general and eco-tourism in particular, so they have the highest coefficient.
Coefficient 2 with criteria: Capacity, Infrastructure, Location and accessibility . Because the assessment area is an island commune of Van Don district, the above criteria are selected by the author with appropriate coefficients at the average level.
Coefficient 1 with criteria: Sustainability. Quan Lan has natural and human-made ecotourism sites, with high biodiversity and little impact from local human factors. Most of the ecotourism sites are still wild, so they are highly sustainable.
3.2.1.6. Results of DLST assessment on Quan Lan island
a. Assessment of the potential for natural tourism development

Basically, both Minh Chau and Quan Lan localities have quite favorable conditions for developing ecotourism. However, Quan Lan commune has more advantages to develop ecotourism in a humanistic direction, because this is an area with many famous historical relics such as Quan Lan Communal House, Quan Lan Pagoda, Temple worshiping the hero Tran Khanh Du, ... along with local festivals held annually such as the wind praying ceremony (March 15), Quan Lan festival (June 10-19); due to its location near the port and long exploitation time, the beaches in Quan Lan commune (especially Quan Lan beach) are no longer hygienic and clean to ensure the needs of tourists coming to relax and swim; this is also an area with many beautiful landscapes such as Got Beo wind pass, Ong Phong head, Voi Voi cave, but the ability to access these places is still very limited (dirt hill road, lots of gravel and rocks), especially during rainy and windy times; In addition, other natural resources such as mangrove forests and sea worms have not been really exploited for tourism purposes and ecotourism development. On the contrary, Minh Chau commune has more advantages in developing ecotourism in the direction of natural tourism, this is an area with diverse ecosystems such as at Rua De Beach, Bai Tu Long National Park Conservation Center...; Minh Chau beach is highly appreciated for its natural beauty and cleanliness, ranked in the top ten most beautiful beaches in Vietnam; Minh Chau commune is also home to Tram forest with a large area and a purity of up to 90%, suitable for building bridges through the forest (a very effective type of natural ecotourism currently applied by many countries) for tourists to sightsee, as well as for the purpose of studying and researching.

3.2.2. Using SWOT matrix to evaluate Quan Lan island tourism
General assessment of current tourism activities of Quan Lan island is shown through the following SWOT matrix:
Table 3.5: SWOT matrix evaluating tourism activities on Quan Lan island
Internal agent
Strengths- There is a lot of potential for tourism development, especially natural ecotourism and humanistic ecotourism.- The unskilled labor force is relatively abundant.- resource environmentunpolluted, still
Weaknesses- Poorly developed infrastructure, especially traffic routes to tourist destinations on the island.- The team of professional staff is still weak.- Tourism products in general
quite wild, originalintact
general and DLST in particularalone is monotonous.
External agents
Opportunity- Tourism is a key industry in the socio-economic development strategy of the province and Van Don economic zone.- Quan Lan was selected as a pilot area for eco-tourism development within the framework of the green growth project between Quang Ninh province and the Japanese organization JICA.- The flow of tourists and especially ecotourism in the world tends toincreasing
Challenge- Weather and climate change abnormally.- Competition in tourism products is increasingly fierce, especially with other localities in the province such as Ha Long, Mong Cai...- Awareness of tourists, especially domestic tourists, about ecotourism and nature conservation is not high.
Through summary analysis using SWOT matrix we see that:
To exploit strengths and take advantage of opportunities, it is necessary to:
- Diversify products and service types (build more tourism routes aimed at specific needs of tourists: experiential tourism immersed in nature, spiritual cultural tourism...)
- Effective exploitation of resources and differentiated products (natural resources and human resources)

Family education and health care are improved. Local education and health systems are upgraded, and community health care systems receive more attention.
To grasp the knowledge of new farming techniques requires farmers

must practice and receive technology transfer from business experts
from the associated industry or from local government agricultural extension training courses.
The support method has helped to improve farmers' knowledge. In order to form specialized areas according to development goals, the province has transferred scientific and technological advances through technical training courses and production methods to develop sustainable raw material areas, creating products with uniform designs and quality. In the past year, the province has provided vocational training to more than 6,400 workers from 25 vocational training establishments and trained more than 200 farming households. Meeting experts and accessing many technical documents from abroad requires people's qualifications to be improved. Therefore, the local education sector has been expanded and developed thanks to the increasing training needs of farming households.
The improvement of people's living standards has raised the demand for health care to a higher level, so commune health stations and local hospitals must be equipped with more advanced medical equipment, and doctors must be reinforced for the grassroots level. Community health is more concerned, many disease prevention and health care programs for children are organized and implemented closer to the grassroots level, the clean water supply system has reached over 5,500 households, accounting for 83% of farming households in the whole province in 2009.
In short, the link between enterprises and farmers not only helps bring more profits to farmers but also creates a more dynamic and attractive local macroeconomic environment to attract more investment capital to Tra Vinh. In addition, farmers produce and cultivate according to standards
GAP also contributes to better environmental protection. People in rural areas
also more aware of family education and community health care, thereby contributing to upgrading the local education and health system. Many farmer support programs have been opened to meet the requirements of cultivation and production with the participation of the state, helping the local government apparatus to be more dynamic and operate more effectively. The result of these factors is that the competitiveness index of Tra Vinh province CPI has always been at the top in recent years.
3.7. Linking "four houses" in Tra Vinh province, advantages, challenges and opportunities
3.7.1. The necessity of linking "four houses" in Tra Vinh province
The agricultural economy of Tra Vinh province has made great strides; many agricultural products have become strengths of Tra Vinh such as shrimp, fish, etc. Farmers' lives have also gradually improved. However, Tra Vinh agriculture is still facing many challenges, especially in the current process of WTO integration. Agricultural production is generally still small-scale, fragmented, lacking planning and direction. Farmers are still struggling with fluctuations in the world market, replanting and cutting down according to the fluctuations of market prices, with epidemics and natural disasters; life is not stable and secure.
Agricultural production is seasonal and greatly influenced by natural conditions such as land, climate, and diseases. Therefore, the agricultural market also has its own specific rules in accordance with supply and demand and prices of agricultural products. Because most farmers have low qualifications and use illegal farming methods, it is difficult to adapt to the market mechanism with unpredictable fluctuations in supply, demand, and prices.
Consumption of agricultural products is still a difficult problem for the majority of farmers. The problem of what to raise? What to plant? What is the quantity and quality? Which market to sell is a difficult problem for farmers over the past time and until now, they are still struggling to solve it! The main disadvantage is the biggest difficulty on the path to developing large-scale agricultural commodity production. There is no production service system that can overcome risks and offset transaction costs to reach farmers. Small-scale farmers in Tra Vinh province, on average, have only 0.6 hectares divided into many small plots of land, cannot apply mechanization and modern scientific and technological achievements to develop large-scale commodity production, and cannot create a stable, uniform source of goods with clear origin and guaranteed quality.
for domestic and international market needs.
On the other hand, the globalization process has unfair “rules of the game” that are disadvantageous to the agriculture of developing countries like Vietnam in general and Tra Vinh province in particular. Farmers of poor countries not only have to compete with farmers of rich countries but also have to overcome the huge subsidies from the governments of these countries. On average, farmers in 30 OECD countries receive support equal to 30% of their total agricultural value each year. Therefore, the competition between small Vietnamese farmers and the modern, large-scale, well-organized and heavily subsidized agricultural production system is unequal. Farmers are even less able to negotiate and cooperate with the system of foreign enterprises that are rich in capital, strong in organization, and connected to powerful national corporations to bring agricultural products to the world market. Therefore, although the international market is open, it is difficult for farmers to participate in that common "playground" with small-scale, fragmented and spontaneous production.
To solve all the above problems and support farmers, it is necessary to have the "participation" of many entities: agricultural product trading enterprises, scientists and support from the State. Only then can we create a strong enough synergy for Vietnamese agricultural products to have a sustainable position in the international market and even in the domestic market. Therefore, the connection of "four houses" is an inevitable requirement in the process of developing agricultural commodity production today.
3.7.2. The "four-house" linkage in Tra Vinh still reveals limitations
- Linkage policy is not complete and consistent.
- The organization and implementation of the policy of linkage; the organization of creating connections between houses… are not good. Therefore, the houses do not have full awareness and understanding of the policy of linkage.
-Infrastructure (transportation, irrigation, etc.) is still limited, causing difficulties and hindering the development of production and business of the Houses, as well as creating conditions to connect the Houses together.
- Planning work still has many limitations and shortcomings.
- The educational and professional level of the scientists is still low and limited (including local scientists and those directly involved in agricultural production and business).
- The connection is not really strong partly because there is no trust between the Houses.
- The qualifications and resources of the Houses are still limited and difficult.
For Farmers
-Education and professional qualifications are still very limited.
- Resources are still limited (especially land scale), so production is mainly small-scale and fragmented, thereby limiting the connection with the House (especially the official connection).
- Resources of capital and basic means of production are still limited and outdated, making it difficult for the participation of the association.
- Assistance and support from other levels, sectors and institutions are still limited and do not meet requirements.
For Scientists
-The qualifications of scientists and technical staff at the grassroots level are still limited.
- Investment capital for science in general, research and technology transfer is still low, not meeting the requirements.
- Equipment for scientific research is still lacking and outdated.
- The regime, policies, support and assistance for Scientists are still low; there is no encouragement or support for Scientists in participating in association with other Scientists (the benefits of Scientists mostly come from funding for programs, topics and projects).
For Business
- Professional qualifications and capacity (especially technical staff) are still limited.
- Limited capital resources, difficulties affecting production and business capacity, as well as expanding and strengthening links with other houses.
- The ability of enterprises to access the market is still limited, affecting product consumption, thereby affecting the connection between enterprises and farmers.
- Support and assistance policies from all levels and sectors... have not met the needs of businesses.
The most basic limitation in the association of four houses in Tra Vinh is the profit sharing between producers and enterprises. Farmers do not sell or only sell part of their products to enterprises. On the contrary, enterprises are stagnant in buying farmers' products when prices fall. This has created a lack of mutual trust, so hesitation in association is inevitable.
Farmers' market awareness is still limited, farmers only focus on production and sales. Therefore, they want to sell all products as quickly as possible without thinking about creating quality products to create a sustainable, long-term market. In addition, the capacity and scale of production of farmers and cooperative economic organizations are still limited. This is a difficult problem for farmers, because the position in the market of farmers is always at a disadvantage compared to buyers - businesses. With a small amount of products, it does not stimulate buyers to cooperate due to high purchasing costs. Moreover, due to the limited production capacity of farmers, they often create products with low quality, so the intermediary cost will increase. Although with the support of the Province in developing cooperative economic organizations to meet the need to expand production scale, the quality of cooperation has only stopped at the initial stage, mainly supporting each other in production techniques. Meanwhile, linking together in contributing capital to production,
expand area, jointly plan production and business, cooperate in finding
Finding a market to consume products is still limited, so production capacity has not been promoted, which limits the ability to connect with businesses.
In Tra Vinh province, although local officials are interested and enthusiastic about the issue of linkage. However, market capacity and dynamism in supporting linkage implementation are still limited. Furthermore, local authorities are almost lacking in providing information to both farmers and enterprises, as well as proactively inviting enterprises to the locality. This reduces the motivation for enterprises to link with farmers.
For scientists in Tra Vinh, there is still a lack of scientists. The province has proactively called on scientists from schools, institutes, etc. to research and promote this connection. However, there are many subjective and objective reasons why scientists are not willing to cooperate in research, such as the payment and settlement procedures are too complicated.
The volume of agricultural products signed for consumption contracts in Tra Vinh is still very low. Decision 80 has set a target: to expand the method of signing contracts for the consumption of agricultural products so that by 2010, over 50% of the output of agricultural products of some large commodity production industries will be consumed through contracts. However, up to now, the target of 50% of agricultural products consumed through contracts is an unachievable task.
Contract breaches still occur quite often for most agricultural commodities. Recently, in Tra Vinh province, there was a phenomenon of businesses breaking their trust, farmers suffered heavy losses, 153 farmers in Thanh Phu commune, Cau Ke district cooperated in production with 9 Tao rice seed company located in Song Loc commune, Chau Thanh district, according to the contract, the company sold seeds to farmers at 11,000 VND/kg if paid in advance and
13,000 VND/kg if paid later. At the same time, the company promised to buy back rice from farmers at 5,200 VND/kg. However, because the company's seeds are mixed with many impurities, it takes a lot of effort to remove them and does not guarantee quality, the company only buys them back at the price of 2,800 - 2,900 VND/kg. The situation of forcing prices and forcing prices by agricultural product purchasing enterprises is common, causing farmers to suffer losses. For farmers and farm owners, the phenomenon of not fulfilling contracts is also quite common in most types of agricultural products, especially when the market has fluctuations in agricultural product prices.
Contracts for agricultural product consumption are not implemented evenly among regions and localities in Tra Vinh province, mainly taking place with some key agricultural export products and in concentrated commodity production areas. In other regions, agricultural product consumption is still basically spontaneous through traders, wholesalers, warehouse owners, and rural markets, so it is unstable.
There has not been a model of linkage in production and consumption for each agricultural product and each production area, so there is no basis for summary and replication. One thing can be seen from the reality in Tra Vinh province: almost all linkages between entities are decided by the market.
Scientific organizations play a very important role in the linkage process. However, up to now, the majority of scientific agencies in Tra Vinh are still confused when implementing the “four-house” linkage. There is still a lack of research agencies or organizations that are bold enough to proactively make the linkage orientation a priority in implementing research programs and projects.
There are many subjective and objective reasons leading to the above limitations. Some of the main reasons can be listed as follows:
Enterprises and especially farmers have not yet properly recognized the necessity and benefits of economic linkages in developing agricultural commodity production, especially in the current context of international economic integration. The signing of product consumption contracts in the past still has many nuances of solving social policies, not an economic lever in the market economy. That is not to mention the "form" of the contract that the province has not been able to manage as
Enterprises sign contracts to consume agricultural products to enjoy some "preferential" policies of the locality. Some enterprises participate in signing contracts to implement the policies of the State and the province, so the signing of contracts is forced, not based on the actual needs of the economic development process, from economic benefits, so the connection with producers is still fragmented and not tight.
The tight binding of responsibilities between the parties in the contract has not been
legalized. Most contracts between enterprises and farmers do not have binding terms; the agreement between the parties is like a memorandum, not an economic contract. Due to limited education level and short-term profit-seeking mindset, failure to calculate long-term strategies as well as inadequate awareness of the responsibility to comply with legal regulations, "Farmers" are very likely to violate the contract during the association process. They do not pay attention to properly implementing the terms of their commitments, leading to the quantity, quality of products and delivery time of goods not complying with the contract. A common situation in Tra Vinh is that many farming households, although having signed contracts and received advance investment in capital and technical materials from enterprises, when the price of products on the market fluctuates, they sell products to other people or other units at higher prices or intentionally sell products to other units to avoid paying for the investments received from enterprises, without thinking about their responsibility for the contract. When the market price drops, they return to selling products to the enterprise that signed the contract with them. On the enterprise side, there are also many enterprises that do not truly respect the signed contracts, not ensuring both the quantity and quality of materials supplied to producers. Due to the lack of strict legal constraints, handling contract violations is very difficult and there is no effective solution.
Due to small-scale, fragmented production, enterprises must sign contracts with farmers with a very large scale of subjects (the current form of agricultural production organization is mainly households, it is very difficult for enterprises to sign contracts with each small farmer). When a contractual incident occurs, it is very difficult to negotiate with such a large number of farmers. On the other hand, with a certain signal (such as a market price signal), it will spread very quickly among the majority and easily lead to pressure on the enterprise subject. Not to mention that enterprises will have to spend a lot of human resources and time to go to each farmer household to sign a contract. Therefore, with the level of accumulation and concentration of agricultural production
In the current business environment, signing contracts between businesses and farmers is not feasible.
Enterprises in Tra Vinh province are still weak and small enterprises have not played a central role in the linkage. In the "four-house" linkage, the role of enterprises is very important: enterprises are the ones who take the initiative to sign contracts with farmers and scientists; guide and help farmers in production orientation, applying technical standards on clean production, food safety and hygiene, technical support, capital, materials, fertilizers, etc. To do that, enterprises must have strong enough production capacity. However, agricultural enterprises currently have many limitations in terms of capital, technology, and collection and distribution networks of agricultural products. In addition, there is a phenomenon that some enterprises have abused their monopoly to squeeze farmers' prices, and have not paid attention to investing in raw material areas.
Due to the backward production level and production practices, not keeping up with the requirements of commodity production, the low production potential of farming households, lack of market information, lack of legal knowledge, most agricultural products are of low quality, uneven, and have no brand; prices and markets often fluctuate, so determining the consumption price of agricultural products when signing contracts is very difficult. Moreover, farmers in Tra Vinh still have a small-scale farmer mentality, only seeing immediate benefits and lacking long-term vision, so it is easy to violate contracts when market prices fluctuate.
There is a lack of a mechanism to ensure harmonious benefits for the subjects participating in the association, especially for scientists.
