RESEARCH PROJECT (BMBR5103) DETERMINANTS OF CONSUMER’S GREEN PRODUCT PURCHASING IN HO CHI MINH CITY STUDENT’S FULL NAME : HUYNH KIM VIET STUDENT ID : CGSVN00014994 INTAKE : MBAOUM0313 ADVISOR’S NAME & TITLE : A PROF NGUYEN PHAN August 2014 Advisor’s assessment Advisor’s signature ACKNOWLEDGEMENTS I would like to thank several people who made this work possible for me with their continuous support and encouragement First of all I am grateful to my thesis supervisor A Prof Nguyen Phan, for his patience, advice and support during my entire thesis work He guided and motivated me during the whole process of my research Secondly, I would also like to thank all the respondents who participated in my survey and I believe that without them this thesis couldn´t be possible I am thankful to my classmates for their time and support during my researching Finally, special thanks go to my families and friends for their continuous support Huynh Kim Viet Ho Chi Minh City, August, 2014 ABSTRACT Today, global warming is one of the major threats towards the planet and many countries, especially coastal countries The weather is changing everyday and disasters are happening all over the places of our planet Now, people all over the world are more concerned with methods to protect the environment For instance, consuming green products or eco-labelled is one of the key ideas that could be carried out by consumers on over the world In developed countries, there has been many research conducted in this area, however, there is limited research worked on developing countries, Asian and Vietnam, especially in Ho Chi Minh market Hence, the objective of this study is to examine the factors that influence consumers to purchase green products in Vietnam, especially in Ho Chi Minh City which is the most crowded population city in Vietnam Due to the environmental issues, green products have got more attention during the latest years and the availability of such products is increasing in many food stores in super market and groceries Governments in some countries are supporting these label products to ensure the sustainable development for environment and a better quality of life for everyone, and for the generations to come I have short-listed several factors during literature review which can influence the consumers green purchase behavior and these factors are; Eco-motivation, Ecoknowledge, Gender, Peer influence, Price and Shelf space The purpose of my study is to get a deeper understanding of the determinants that can affect customer‟s green product purchasing of food products in Ho Chi Minh City Thus my main research question that I want to answer with this study is: “Which are the most important factors that influence the purchase behavior of eco-labelled products?” This quantitative study is carried out in Ho Chi Minh City, Viet Nam with 200 respondents and focuses mainly on the food market consumers (super market and groceries) I stand on researcher position for this study and I believe that cross-sectional research design is most suitable to fulfill my research purpose I developed several null hypotheses and for this purpose I distributed my research questionnaire at the entrance of different super markets and groceries in Ho Chi Minh City, Viet Nam to collect my data from the respondents I applied convenience sampling with simple quota to this research I dissected and evaluated the gathered data with help of SPSS Key words: Purchase decision, Green marketing, Eco-labeling, Shelf space, Ecomotivation, Eco-knowledge, Gender, Price, Peer influence, Green product, Green marketing, Green consumer profile, Ho Chi Minh consumers Table of contents Chapter 1: Introduction 1.1 Problem background 1.2 Research purpose and research questions 1.3 Limitations 1.4 Definitions of key terms 1.5 Disposition of the study Chapter 2: Literature review 2.1 Green marketing 2.1.1 Green consumer behavior;

a global action program for sustainable development was introduced with the name of „Agenda 21‟ In this meeting „eco-labeling‟ was identified as a way to encourage consumers to more sustainable consumption choices Nowadays more ecolabelled products are available when it comes to almost all kind of products in the stores, especially in the food stores The growing interest of consumers in environmental protection has compelled many companies to be actively involved in making their products greener This growing interest in climate change during the past couple of decades led to increased demand for green labeling, which allow the consumers to differentiate between more and less sustainable options (Horne, 2009, p 175) It has also been shown that the interest in being green and the purchasing of eco-friendly products continues to grow (Orange, 2010, p 29) All the different selections between products that consumers make on a daily basis have an impact on the environment It is believed that different factors can affect the customers during the evaluation process of eco-labelled products and therefore there are different reasons underlying the purchase decision such as the price difference Thøgersen suggests avoidance of too large a price gap between eco-labelled and conventional products (Thøgersen, 2006, p 1774-1776) When it comes to knowledge about eco-labels, there exist some potential barriers for some consumers because they face problems understanding the contents of different eco-labels in the store, while others find the information‟s hard to read (Leire & Thidell, 2004, p 1068; D´Souza Taghian & Lamb, 2006, p 168-170) Some of the consumers distrust the eco-labels and their credibility has also been questioned by several researchers (Erskine & Collins, 1997, p 125; Nilsson, Tuncer & Thidell, 2004, p 517; Orange, 2010, p 29; Horne, 2009, p 176) Some companies use the symbol of a leaf, flower or fish on their labels (though these are not eco-labels) which has the potential to confuse the consumers (Naturskyddsföreningen, 2012) Leire & Thidell (2004) and Thøgersen (2000) discuss the importance of eco-motivation (which influences the purchase behavior of eco-labelled products) in their separate studies It has been investigated whether demographic factors can affect consumer behavior and the potential influence of attitudes (Fransson & Gärling, 1999, p 371) During purchase decisions people may consider others opinions which may be their friends or family members (Solomon, Bamossy, Askegaard & Hogg, 2006, p 155-156) My study tries to investigate the influence of above-mentioned factors on the purchase behavior of eco-labelled food products Being author, I am motivated to an empirical study which targets the customers of Ho Chi Minh City, Vietnam These factors have mostly been investigated separately by different researchers; in contrast, here I study them together for their influence on the purchase decision of eco-labelled food products This study will give me an opportunity to understand which factors have more influence in stimulating green purchase of food products 1.2 Research purpose and research questions The purpose of this study is to get a deeper understanding of the factors that can affect green purchase of food products in Ho Chi Minh City It is of importance to know what is having the greatest impact on the consumers to buy or not to buy these eco-labelled products The main research question that I want to answer with my study is: “Which are the most important factors that influence the purchase behavior of eco-labelled products?” 1.3 Limitations I have restricted this study to food products where an eco-label can be applied This decision was done due to limited resources; it will be beneficial to extend this study to other products too The study was carried in Ho Chi Minh City, Vietnam which can not represent the characteristics of whole consumer food market on over the world or over Vietnam region My sample size is quite small as I have planned to have 200 respondents, in comparison with the whole Ho Chi Minh population, approximately 10 millions Beside this, my method of data collection is convenience sampling which cannot result in a representative sampling, so it is quite hard to generalize my results to the whole food market During data analysis I faced several problems which are concerned about the responses about several questions For some questions I have got more than 95% responses for one option in the question, some responses not answering income question, which limits my testing capacity Finally, I have limited this research to evaluate only six factors due to time constraints andI suggest to include other factors too for example; age, education, gender, income, lack of time, guilt for the environment, habits, norms, values, packaging, and brand name 1.4 Definitions of key terms: Agenda 21: Agenda 21 is a comprehensive plan of action to be taken globally, nationally and locally by organizations of the United Nations System, governments and major Groups in every area in which human impacts on the environment Agenda 21, the 10 Factor Analysis KMO and Bartlett's Test Kaiser-Meyer-Olkin Measure of Sampling Adequacy Bartlett's Test of Approx Chi- Sphericity Square 640 345.055 Df Sig 21 000 The over table show two tests that indicate the suitability of my data for structure detection The Kaiser-Meyer-Olkin Measure of Sampling Adequacy is a statistic that indicates the proportion of variance in your variables that might be caused by underlying factors High values (close to 1.0) generally indicate that a factor analysis may be useful with my data If the value is less than 0.50, the results of the factor analysis probably won't be very useful Bartlett's test of sphericity tests the hypothesis that your correlation matrix is an identity matrix, which would indicate that my variables are unrelated and therefore unsuitable for structure detection Small values (less than 0.05) of the significance level indicate that a factor analysis may be useful with my data 52 Communalities Initial Extraction Gender 1.000 662 Understandability 1.000 663 Price 1.000 769 Shelf space1 1.000 474 Shelf space2 1.000 502 Peer influence 1.000 863 Price 1.000 952 Extraction Method: Principal Component Analysis Total Variance Explained Compo nent Extraction Sums of Squared Rotation Sums of Squared Loadings Loadings % of Cumulative % of Cumulative Initial Eigenvalues % of Cumulative Total Variance % Total Variance % Total Variance % 2.430 34.711 34.711 2.430 34.711 34.711 2.357 33.665 33.665 1.428 20.403 55.114 1.428 20.403 55.114 1.496 21.367 55.032 1.027 14.673 69.787 1.027 14.673 69.787 1.033 14.755 69.787 822 11.744 81.532 619 8.850 90.381 474 6.765 97.147 200 2.853 100.000 Extraction Method: Principal Component Analysis 53 Component Matrix(a) Component Peer influence 881 -.280 Price 856 -.179 Understandability 808 Gender 256 722 Shelf space1 -.275 680 Shelf space2 439 557 Price 124 965 Extraction Method: Principal Component Analysis a components extracted Rotated Component Matrix(a) Component Peer influence 925 Price 872 Understandability 804 Gender 121 789 -.193 160 Shelf space1 -.128 658 Shelf space2 272 650 Price 974 Extraction Method: Principal Component Analysis Rotation Method: Varimax with Kaiser Normalization a Rotation converged in iterations 54 From the above table show that determinants of consumer‟s green products in Ho Chi Minh City are peer influence, price and understandability Component Transformation Matrix Component 963 268 036 -.270 958 099 -.008 -.105 994 Extraction Method: Principal Component Analysis Rotation Method: Varimax with Kaiser Normalization 55 Chapter 5: Conclusion of the Study In this part of the thesis, I discuss, interpret and conclude the meaning of our study results I also find out and discuss if I have answered my research questions and fulfill the purpose with the study Finally, in the end of this chapter of the thesis I will discuss my contribution with my study and also try to give some further recommendations to other researchers 5.1 The Influencing Factors Eco-labeling; a marketing tool to help the consumers in their decision making plays a substantial role in raising the consumer‟s awareness about environmental protection and such awareness guide the consumers in green purchasing On the other hand, there are several factors which may influence the purchase behavior of eco-labelled products Most of the studies have been conducted on the effectiveness of eco-labeling and consumer attitude towards environmental products but some of them have missed to investigate income There is limited combine research available regarding eco-labeling and these factors; therefore, I have decided to investigate the influence of various factors on the purchase decision of eco-labelled products in Ho Chi Minh City, Vietnam The purpose of this study is mainly to understand the most important factors that can influence the purchase behavior of eco-labelled products For this purpose, I select several elements to understand the actual role of these factors regarding purchase behavior of eco-labelled products Eco-motivation, eco-knowledge, gender, peer influence, understandability and price was taken along with education The relationship between these six elements and interest in eco-labelled products were tested in the first phase of statistical analysis and successfully pointed out the different elements which has the potential contribution in the interest development towards eco-labelled products High education and affecting from other people towards eco-labelled products can be transformed into environmental purchase Strong influence of eco-motivation is showing 56 that this is an important factor in the purchase decision If the consumer has trust, belief and knowledge in the eco-labelled products he/she will certainly be motivated to buy these types of products On the other hand, my study shows statistically insignificant relationship between peer influence and interest in eco-labelled products The correlation test shows statistically significant positive relationship between peer influence and the actual purchase of eco-labelled products Therefore peer influence is the most important factor that influences the purchase decision and the focus should be mainly on eco-motivation and peer influence The researching show that the price factor affect on consumers to buy green product, that mean the price has a important role in buying green products 5.1.1 Our Research Contribution I limit my research to the influence of above discussed seven factors on the consumers purchase behavior of eco-labelled products which is different from other researchers work as mostly they have investigated ecological behaviors and eco-labeling I believe that this study will contribute with new valuable research in the area of eco-labeling in the Ho Chi Minh consumer food market My theoretical part investigates the available information about eco-labeling, eco-motivation, eco-knowledge, price, peer influence, gender and education while the empirical part has evaluated these variables which can influence the purchase beha behavior of eco-labelled products I have found that ecomotivation and shelf-space contributes in the creation of actual purchase of eco-labelled products As eco-labelled products in some cases have had problem with penetrating the market so it is of value to have the right knowledge of the valuable marketing tools that affect the consumers more or less while making their purchasing decision of green products This dimension of our research will help the researcher while working on a similar topic I recommend to producers and retailers to provide eco-labelled products in the Ho Chi Minh market as my research shows positive correlation between income and 57 purchase behavior of eco-labelled products and they can increase the sale of these products as there is sufficient eco-motivation 5.1.2 Research Recommendations For marketers, I strongly recommend to use eco-labeling as a one of the marketing strategy (as a communication tool to satisfy various stakeholders) and to provide the eco-labelled products in the supermarket in Ho Chi Minh City to ensure the availability of eco-labelled products The availability of eco-labelled products in the supermarkets can create the attention or interest of the consumers, this interest can be changed into purchase by other tools Marketer can consider green product for the future development of the company The eco-motivation and eco-knowledge contributes strongly in the creation of interest in eco-labelled products, so I suggest the marketers to increase the eco-motivation and eco-knowledge of the Ho Chi Minh consumers For this purpose, I think that in eco-labelled products exhibitions, seminars and advertisement can play vital role These elements contribute in the development of interest towards eco-labelled products Eco-motivation and eco-knowledge are the strongest elements which create attention towards eco-labelled products If I look at the sub-variables of eco-knowledge for example; many of the respondents believed that it is important to be environmental friendly Belief is also considered one of the strong element in developing ecomotivation, I suggest marketers to increase the eco-motivation of the Ho Chi Minh consumers by some promotional activities One of the eco-motivation questions was covering if there were any influence of price of eco-labelled products and for this query I recommend to make it clearer and more visible for the consumers that how the product has been produced, packaged, transported and delivered to make it more trustworthy and to increase the eco-motivation of the consumers For further research in this area I recommend the researchers to conduct the research 58 with bigger sample in a bigger city or cities to be able to generalize the results to the whole population It will be also beneficial if someone can conduct study on the same topic with qualitative approach as it will be valuable to know the point of view of supermarkets managers regarding the role of price, peer influence and understandability influence in the selection of green products It is a subject which I find in need of further research and there can be many underlying factors that I haven´t found in this research which may affect the consumers in the store 59 References Baron, O., Berman, O., & Perry, D (2010) Shelf Space Management When Demand Depends on the Inventory Level Production and Operations Management 20(5), 714726 Bryman, A., & Bell, E (2011) Business research methods, 3ed.Oxford University Press Carrete, L., Castano, R., Felix, R., Centeno, R., & Gonzalez, E (2012) Green consumer behavior in an emerging economy: confusion, credibility, and compatibility Journal of consumer marketing 20 (7), 470-481 Chen, Y-L., Chen J-M & Tung, C-W (2006) A data mining approach for retail knowledge discovery with consideration of the effect of shelf-space adjacency on sales Elsevier, 1503-1520 Dahm, M.J., Samonte, A.V., & Shows, A.R (2009) Organic foods, eco-friendly attitudes predict eco-friendly behaviours?
