vegetable in all seasons However, as the farmers focus too much on productivity, intensive cultivation, and increasing crops, they tend to fertilize plants and use insecticides, pesticides, growth stimulants indiscriminately According to the report of Mr Nguyen Xuan Hong, Director General of Plant Protection Department, 80% of plant protection chemicals were used in the wrong way and Vietnamese farmers could reduce 50% amount of plant protection chemicals using without any affect to productivity (MARD, 2014) Not only environment pollution, time and money extravagance, the overuse of plant protection chemicals also cause food poisons and many diseases to human such as cancer, kidney dysfunction, toxicity to the nervous system, etc As a result, the safety of vegetable is a key issue in Vietnam and becomes an objective of Foot Safety National Strategic Programme: “To 2015, 30% planting farms would have applied VietGAP” (MOF, 2011) Vegetables are considered as safe when the nitrate and heavy metals, pesticide, and microbial contamination levels are below the standard level which is issued by the MARD (2008) Nowadays, people get used to the term “Organic Vegetable” Organic vegetable is vegetable grown and processed by methods that not use any synthetic materials, such as chemical pesticide, synthetic fertilizer and growth stimulants (FAO, 1999) More and more companies invest in organic food business such as An Hòa Co., Organic Farm, Golden Garden, Nông nghiệp GAP, Ánh Ban Mai, Homefood, Mr.Sạch, Tràng An, Bác Tôm, Organica, Organic Roots, etc According to Ms Regina Loo – Marketing Director at Big C Vietnam in 2014, not only the increasing awareness on health, food safety and environmental concerns that cause an increase in demand for organic foods, the income per capita in Vietnam getting higher is also a reason There is a rise in the number of households who choose organic vegetables for their meals They are willing to pay a premium for organic vegetables 1.2 Problem statement However, the increasing demand of organic vegetable does not guarantee a promising market for organic vegetables Preliminary observations revealed that high price is the first disadvantage For example, according to State Management Information of Price and Valuation, in Feb 2014, the price of Cabbage (“Bap Cai”) in traditional market is around 12,000-15,000 VND/KG, while it is 25,000-30,000 VND/KG for organic vegetable, two times more expensive, while buyers are not sure that the higher price one is really safe On other hand, limited supply caused by high cost cultivating as well as limited products availability and variability, customers cannot buy their favorite organic vegetable at the most convenience (Trinh, 2014) Those disadvantages make the demand of organic vegetable still low against rising demand Given this situation, the problem of concerns by managers and marketers in related organizations is how to increase the acceptance of Vietnamese consumers towards organic vegetable Thus, it is necessary to identify the key factors and measuring their influence on the willingness to buy organic vegetables This helps to clarify the buying motives and buying barriers, improve knowledge and understanding to draw managerial implications Previous studies mainly focus on consumers awareness towards organic vegetables with research objectives are local Vietnamese in general (Truong et al., 2012; Mergenthaler et al., 2009) Then, the results might not reflect the true image of organic vegetable consumption and it is difficult to understand how willingness to purchase organic vegetable are affected by changes of other indicators such as price, convenience, consumption trend, etc Bien Hoa City, Dong Nai Province is selected as a case to test the model The city is only 30 kilometers away from Ho Chi Minh City Center, growing fast in recent years with new food stores, malls, supermarkets appeared The research will assess the level of family food buyers’ awareness of health, trust and perception of certificated organic vegetable, price consciousness and buying convenience influence on willingness to buy organic vegetable in Bien Hoa City The findings can benefit organic vegetable sellers and retailers in developing appropriate sales and marketing strategies by improving understanding of potential Vietnamese consumers – the family food purchaser It may also help government to design strategies for consumer education on the benefits of going organic 1.3 Research objectives and aims The proposed model will be tested in the context of Vietnam, Bien Hoa City specifically As problems stated above, the research objectives are indicated as to identify the key factors and measure their influence on consumers’ willingness to buy organic vegetable Its aim is to guide future awareness raising, advocacy and marketing activities of the organic sector in Viet Nam 1.4 Thesis structure The structure of this research is organized in five chapters  Chapter is concerned with the introduction of the thesis which includes research background, research problems and research objectives  Chapter reviews relevant literature regarding the Theory of Planned Behavior of Icek Ajzen and preliminary researches in organic vegetable Through the discussion, the hypotheses and research model will be developed for the testing which is mention in the next chapter  Chapter introduces the design of the research This chapter starts with research validity and reliability and goes to stage of data collection in assessing the perception and awareness of consumers as well as measuring the influence of the main factors on their willingness to purchase organic vegetable The discussion on research population, research sample, data collection procedure and regression model for testing hypotheses are also included in this chapter  Chapter shows the strategy of data analysis and discusses the findings This chapter will provide a summary of testing results for hypotheses given in the chapter  Chapter relates to the conclusions, implications and limitation Suggestions of further research are also mentioned in this chapter Perceived Convenience: Most consumers had negative attitude toward Convenience when buying organic vegetable 163 and 191 interviewees (out of 202) stated that organic vegetable was not easy to buy and not enough species for choices, respectively Hence, the variable Convenience appeared not to attribute to explain consumers’ Willingness to Purchase organic vegetable In fact, increase the Convenience of buying and using organic vegetable may increase the consumers’ Willingness to Purchase Once again, the R&D should be focused to find the best way to store and reserve as organic vegetables don't last long since they not contain preservatives This can help organic vegetable to be more widely distributed, improve its current limited availability 42 CHAPTER 5.1 CONCLUSIONS AND LIMITATIONS Summary of research Organic vegetable must be made available since consumers’ concerns on food safety, quality and nutrition increases, this will be expected to lead to an increase in demand yet there seems to be a gap in the Vietnamese market where many key informants are of the view that price and availability is a serious issue – the price is high and there are not enough suppliers and the few who are there are not reliable That affects the consumers’ Willingness to Purchase and lower organic vegetable consumption This is the most concerns of organic vegetable organizations’ managers and marketers To solve the problem of concerns, a study was undertaken with the main purpose is identifying the main factors that affect the consumers’ Willingness to Purchase organic vegetable Demographic characteristics such as age, educational level, monthly expense for food, presence of children in the family would affect the willingness to purchase organic vegetable Particularly, family food purchaser with high age, educational level and monthly expense for food were more likely to buy organic vegetables, reflect their awareness of health and affordability Research also showed presence of children in family positively influences the organic food purchase Furthermore, to add explanation value in studies concerning willingness to purchase organic vegetable of Bien Hoa consumers, based on the framework of Theory of Planned Behavior, the author had proposed a model with six factors: Health Concerns, Subjective Norms, Self-Awareness, Perceived Benefits, Perceived Price and Perceived Convenience However, based on the data analysis, only four factors resulted having significant influence on Willingness to Purchase: Health Concerns, Subjective Norms, Awareness of Benefits (combination of Self-Awareness and Benefits) and Perceived Price 43 Perceived Price is the most important consideration when shopping Although organic vegetables present very attractive benefits of consumption, they are significantly more expensive than non-organic and most who consume them are middle to upper class persons as the majority belong to the lower social classes and cannot afford organic vegetable daily More than 70% interviewees stated that organic vegetable was expensive, hence price need to be perceived as affordable in order to increase Willingness to Purchase of consumers Awareness of Benefits played the important role determining Willingness to Purchase The higher the awareness’, the consumers are more likely to purchase organic vegetable rather than non-organic Therefore, consumers really need to be educated and exposed to the benefits of organic products for consumption levels to grow Also, to build trust on consumers, the organic vegetable verifying system need to be improved such as standards, mark, verification and control The companies have to supply sufficient information about how organic procedures are ensured in growing, processing and even delivery stage Subjective Norms resulted in influencing both consumers’ Awareness of Benefits and Willingness to Purchase, hence it should be an effective communication mean to the market and especially on young people and children to carry the organic idea into the future The most popular norms about organic foods is word of mouth and teachings at school or college Other popular norms included television programs or adverts and radio programs or adverts Health Concerns were supported to have significant impact on consumers’ Willingness to Purchase via Aware of Benefits From the survey, most family food buyer were female, as such, did have positive concerns of health and food safety Most people know or understand much about what organic vegetable are, but not ask specifically for organic vegetable As such, it pointed out the gap between positive Awareness towards purchasing behavior and Willingness to Purchase organic vegetable 44 Farmers, traders, organizations and government should come together to negotiate equivalencies of the going organic strategy, promote the above factors which in turn influence positively to consumers’ Willingness to Purchase The main reasons for starting this process are meeting consumer expectations, preventing fraud and adapting the legislation to the fast-growing sector and market To conclude, the author recommends that researchers and manufacturers and suppliers in the organic sector would focus on the importance of reasonable price and affective attitude to increase willingness to organic vegetable consumption 5.2 Limitations Due to limited of time as well as the author skills and knowledge, this study has a number of limitations:  Firstly, EFA should be conducted for all scales, including independent and dependent variables  Secondly, the numbers of items in a scale were rather few Therefore, when using EFA, some items were eliminated from the model and caused combination of factors Perceived Benefits and Self-awareness, which may affect the quality of the research  Thirdly, adjusted R squared of 0.64 was acceptable, but as only explained 64% variation of Willingness, more research should be done to examine if there were other factors influence the consumers’ Willingness to Purchase organic vegetables rather than those factors mentioned above  The fourth limitation belonged to the questionnaire design As the questionnaire contained many items, the author should have used the 7-point scale or more to avoid similarity and combining items among factors  Finally, another limitation in data collection was the heteroscedasticity, which could lead to bias in test statistics and confidence intervals 45 5.3 Suggestion for further researches As the study tested the factors that applied to Willingness to Purchase organic vegetables in Bien Hoa only, conducting a similar study in other sectors, industries or areas may not achieve the similar results Therefore, further research should be done to broaden the scope of this study and/or to include other constructs relating to willingness to purchase organic products to capture more comprehensive picture in this industry Future researches could also include more specific segmentation bases such as different age groups, or consumers with different income levels and could be undertaken in greater detail 46 REFERENCES Ajzen, I (1988) Attitudes, personality, and behavior Chicago: Dorsey Press Anderson, J., Gerbing, W (1988) Structural equation modelling in practice: A review and
