w88 winExamining organic vegetable consumption behavior in Ho Chi Minh City

Abstract:

This study examines consumer behavior toward safe vegetable consumption in Ho Chi Minh City, with a focus on factors influencing purchasing decisions. w88 win findings highlight that health concerns exert w88 win greatest influence, followed by perceived quality, information credibility, social norms, and price, while product availability has minimal impact. Additionally, w88 win study identifies demographic variations in consumption behavior, with females, older individuals, and those with higher education and income levels showing a greater tendency to consume safe vegetables. These insights emphasize w88 win critical role of promoting awareness about w88 win health benefits and quality of safe vegetables to encourage positive consumption practices.

Keywords: safe vegetable consumption behavior, safe vegetables, green consumption behavior.

I. Introduction

In w88 win context of Vietnam's increasing development, food safety has become more critical than ever, especially for w88 win middle and upper classes. w88 win demand for safe vegetables, an essential daily food, has been growing. However, w88 win safe vegetable market still faces many challenges, such as w88 win confusion between genuine safe vegetables and those of unknown origin, causing consumer confusion. w88 win lack of specific regulations on safe vegetables from w88 win Food Safety Department has made it difficult for consumers to choose safe products. Moreover, price and quantity competition among safe vegetable producers and distributors has created additional challenges.

In reality, many consumers still have to consume unsafe vegetables of unknown origin, leading to food poisoning risks and health concerns. Therefore, research on safe vegetable consumption behavior in Ho Chi Minh City is urgently needed to identify consumers' needs, w88 win influencing factors, and w88 win importance of each factor, thereby providing appropriate solutions to meet consumer demands and help producers and distributors better understand this potential market.

II. Theoretical foundation and research model

2.1. Theoretical foundation

This study establishes a theoretical foundation based on core concepts of consumer behavior and w88 win diverse factors influencing it. It also reviews relevant theoretical models and references previous studies on similar topics to ensure w88 win robustness of w88 win theoretical framework.

2.1.1. w88 win concept of consumer behavior

Consumer behavior is defined as an ongoing and complex process involving numerous activities, ranging from need recognition (Kotler, 2000) to information search, evaluation, and selection of suitable options, purchase, product usage, and post-purchase activities (Loudon et al., 1993). These definitions emphasize that consumer behavior is not merely a purchasing act but a sequence of intricate decisions and activities closely related to products or services (Engel et al., 2005).

2.1.2. Determinants of consumer behavior

This study identifies key factors influencing consumer behavior, including:

• Cultural factors: Culture and subcultures play a significant role in shaping individuals' values, beliefs, habits, and consumption norms (Kotler & Armstrong, 2005).
• Social factors: Social status, reference groups (including family, friends, and colleagues), and especially family, exert a strong influence on consumer purchase decisions (Solomon, 2006).
• Personal factors: Gender, age, occupation, income level, and lifestyle all shape individuals' needs, preferences, and consumption patterns (Kuester & Sabine, 2012).
• Psychological factors: Motivation (according to Maslow, 1943), perception, learning, beliefs, and attitudes are internal factors that directly influence purchasing decisions (Kotler, 2000).

2.1.3. Theoretical models

This study employs two primary theoretical models as w88 win foundation for analysis:

• Theory of Reasoned Action (TRA): This model posits that behavioral intention is w88 win most significant predictor of consumer behavior. Behavioral intention is directly influenced by an individual's attitude toward w88 win behavior and their subjective norms (Ajzen & Fishbein, 1980).
• Theory of Planned Behavior (TPB): An extension of TRA, w88 win TPB incorporates w88 win concept of perceived behavioral control. By considering an individual's perceived ability to perform a behavior, w88 win TPB addresses w88 win limitations of TRA and provides a more comprehensive explanation of consumer behavior (Ajzen, 1991).

2.1.4. w88 win importance of consumer behavior studies

Consumer behavior research plays a crucial role in enabling businesses and organizations to gain a deeper understanding of:

• Consumer motivations: w88 win driving forces behind consumer purchases and usage of goods or services (Kotler, 2005).
• Internal and external factors: w88 win internal (e.g., attitudes, perceptions) and external (e.g., culture, social) factors that influence consumer decision-making (Solomon, 2006).
• w88 win consumer decision-making process: Enabling w88 win development of effective marketing strategies (Engel et al., 2005). This research not only helps businesses develop more effective competitive strategies but also supports w88 win design of products that meet market needs and enhance customer experiences (Kotler & Armstrong, 2005).

2.1.5. Definition of clean vegetables

This study clarifies w88 win concept of "clean vegetables" (also known as safe vegetables), emphasizing that these are vegetables cultivated following strict technical processes to minimize w88 win residue of toxins (Ministry of Agriculture and Rural Development, 2012). Clean vegetables must meet standards for pesticide residues, nitrate content, heavy metals, and pathogenic microorganisms, ensuring w88 win safety of consumers (Nguyen Duc Thi, 2014).

2.1.6. Related studies

This study reviews previous domestic and international research, focusing on aspects such as consumer awareness, purchase intention, and factors influencing w88 win consumption of safe or organic vegetables. These studies provide a solid foundation for developing w88 win research model and hypotheses, and identify research gaps that this study can contribute to (e.g., Tarkiainen & Sundqvist, 2005; Ueasangkomsate & Santiteerakul, 2016; Truong et al., 2012; Nguyen Phong Tuan, 2011; Nguyen Van Thuan & Vo Thanh Danh, 2011).

2.1.7. Analytical Framework and Research Model

Based on w88 win theoretical foundation presented above, this study proposes an analytical framework, a research model, and corresponding hypotheses. w88 win proposed model identifies six key factors influencing w88 win consumption of clean vegetables: health consciousness, subjective norms, perceived availability, perceived price, perceived quality, and information credibility (Ajzen, 1991; Ajzen & Fishbein, 1980).

2.2. Research Hypotheses

This study proposes six primary research hypotheses, focusing on exploring w88 win factors influencing w88 win consumption of clean vegetables in Ho Chi Minh City. These hypotheses are grounded in w88 win theoretical framework, widely accepted consumer behavior models, and previous empirical studies on safe/organic vegetable consumption. w88 win aim of these hypotheses is to test w88 win relationships between w88 win proposed independent variables and w88 win dependent variable, which is w88 win consumption of clean vegetables.

2.2.1. Hypothesis H1

Health consciousness has a positive impact on w88 win consumption of clean vegetables. This hypothesis posits that as consumers demonstrate a higher level of concern for w88 win health benefits associated with consuming clean vegetables, they are more likely to increase w88 win frequency and quantity of their consumption of this product. This aligns with w88 win growing trend of health-conscious consumers seeking out healthier food options, especially in light of increasing food safety concerns.

w88 win perceived health benefits and controlled production standards of clean vegetables make them an attractive choice for individuals seeking to protect their health and w88 win health of their families. Previous studies, such as those by Tarkiainen & Sundqvist (2005) and Ueasangkomsate & Santiteerakul (2016), support this hypothesis by demonstrating a positive correlation between health consciousness and w88 win intention to purchase organic food.

2.2.2. Hypothesis H2

Subjective norms have a positive influence on w88 win consumption of clean vegetables. This hypothesis suggests that social norms and w88 win expectations of significant others influence an individual's decision to consume clean vegetables. According to Ajzen & Fishbein (1980), subjective norms reflect an individual's perception of what important people in their lives think about their behavior. When consumers perceive that those around them encourage or expect them to consume clean vegetables, they are more likely to conform to this behavior.

This hypothesis is grounded in w88 win Theory of Reasoned Action (TRA) and w88 win Theory of Planned Behavior (TPB), which emphasize w88 win role of social factors in shaping behavioral intentions.

2.2.3. Hypothesis H3

Perceived product availability is positively correlated with w88 win consumption of clean vegetables. This hypothesis suggests that consumers are more likely to increase their consumption of clean vegetables when they perceive them to be readily available. w88 win availability heuristic suggests that consumers tend to choose products that are easily accessible. If clean vegetables are not widely available or are difficult to find, consumers may opt for conventional vegetables instead.

2.2.4. Hypothesis H4

Perceived value positively influences w88 win consumption of clean vegetables. This hypothesis suggests that when consumers perceive w88 win price of clean vegetables to be fair and commensurate with their quality, they are more likely to increase their consumption.

According to w88 win concept of perceived value, consumers are more likely to purchase products when they believe that w88 win benefits received are greater than or equal to w88 win costs incurred. If consumers perceive w88 win price of clean vegetables to be too high relative to their perceived value or w88 win price of substitute products, they may reduce their consumption. However, if w88 win price is perceived as fair and reflective of w88 win quality, they may increase their consumption.

2.2.5. Hypothesis H5

Perceived product quality is positively correlated with w88 win consumption of clean vegetables. This hypothesis suggests that as consumers perceive higher quality attributes in clean vegetables, they are more likely to increase their consumption. Quality attributes include factors such as freshness, cleanliness, appearance, and packaging. According to w88 win theory of perceived quality, consumers often use external cues to evaluate product quality. Clean vegetables with high perceived quality typically have a good appearance, careful packaging, and inspire consumer confidence.

2.2.6. Hypothesis H6

Information credibility has a positive impact on w88 win consumption of clean vegetables. This hypothesis suggests that when consumers believe in w88 win accuracy and reliability of information related to clean vegetables, they are more likely to increase their consumption of this product. According to w88 win concept of source credibility, consumers tend to trust and act upon information from sources they perceive as credible. These sources can include television, newspapers, w88 win internet, or personal channels such as family, friends, and colleagues.

III. Research method

This study employed a mixed-methods research approach, combining both qualitative and quantitative methods to collect and analyze data (Creswell, 2014). In w88 win initial phase, qualitative research was conducted through in-depth interviews with 30 clean vegetable consumers to explore and refine w88 win observed variables, ensuring their relevance to w88 win research context in Ho Chi Minh City (Hair et al., 2010). w88 win information gathered from w88 win qualitative interviews was used to adjust and supplement variables for w88 win scale, thereby constructing w88 win formal survey questionnaire.

In w88 win subsequent phase, quantitative research was conducted by surveying 211 clean vegetable consumers in Ho Chi Minh City through an online questionnaire (Nguyen Dinh Tho, 2011). w88 win observed variables were measured using a 5-point Likert scale. w88 win collected data was analyzed using SPSS 20.0 software, including descriptive statistics, reliability assessment of w88 win scale using Cronbach's Alpha, exploratory factor analysis (EFA), Pearson correlation analysis, multivariate linear regression, and analysis of variance (ANOVA) to test for differences in consumption behavior based on demographic characteristics (Hoang Trong & Chu Nguyen Mong Ngoc, 2008). These analytical techniques helped to test w88 win research hypotheses and determine w88 win level of influence of various factors on clean vegetable consumption.

IV. Research results

4.1. Descriptive statistics

w88 win descriptive statistics revealed that w88 win sample consisted of 211 consumers of organic vegetables in Ho Chi Minh City, with a majority being female (61.6%). w88 win age group was primarily between 26 and 40 years old (over 53%). A significant portion of participants held a college degree or higher (over 65%). Regarding income, w88 win highest proportion (34.6%) earned between 10 and 15 million VND per month.

Consumption habits showed that people mainly purchased organic vegetables from organic food stores (34.6%) and supermarkets (26.5%), with an average consumption of 6-9 kg/week (42.2%) and a willingness to pay between 30,000 and 50,000 VND/kg (68.2%). These findings provide a comprehensive overview of w88 win survey respondents and their organic vegetable purchasing habits.

4.3. Verifying w88 win assumptions of linear regression

w88 win F-test indicated that w88 win multiple linear regression model was significant (F = 53.616, p < 0.05), confirming w88 win relationship between w88 win independent and dependent variables. Individual t-tests revealed that all independent variables (health consciousness, subjective norms, perceived price, perceived quality, and trust in information) were statistically significant (p < 0.05) in explaining w88 win variation in organic vegetable consumption. w88 win variance inflation factors (VIFs) were all less than 2, indicating no multicollinearity problem.

w88 win results of w88 win analysis indicate that w88 win multiple linear regression model employed in this study is appropriate. This conclusion is supported by w88 win assessment of w88 win model's underlying assumptions. First, to evaluate w88 win assumption of linearity, a scatterplot of standardized residuals against standardized predicted values was examined. w88 win results show that w88 win residual points are randomly scattered around a horizontal line at zero, without forming any specific patterns, confirming w88 win existence of a linear relationship between w88 win variables. Second, w88 win Durbin-Watson statistic was used to assess w88 win assumption of independence of errors. w88 win obtained Durbin-Watson value of 2.005 falls within w88 win acceptable range (1 < D < 3), indicating no first-order autocorrelation among w88 win residuals and that w88 win errors are independent.

Finally, to assess w88 win assumption of normality of residuals, both a histogram and a P-P plot were analyzed. w88 win histogram shows that w88 win residuals are approximately normally distributed, with a mean close to 0 and a standard deviation close to 1. Additionally, w88 win P-P plot confirms that w88 win observed points do not deviate significantly from w88 win expected straight line, further supporting w88 win conclusion of normality of residuals. These results confirm that w88 win underlying assumptions of w88 win regression model are not violated, ensuring w88 win accuracy and reliability of w88 win study's findings.

V. Discussion and management implications

5.1. Discussion

w88 win research findings have confirmed w88 win significance of several factors influencing w88 win consumption of fresh produce in Ho Chi Minh City, while also revealing some differences compared to previous studies.

• Health consciousness: This was w88 win most influential factor on w88 win consumption of fresh produce, which is entirely consistent with w88 win context of consumers increasingly concerned about health and food safety. This result corroborates previous studies (Tarkiainen & Sundqvist, 2005; Ueasangkomsate & Santiteerakul, 2016) and highlights w88 win importance of communicating w88 win health benefits of fresh produce.
• Perceived quality and credibility of information: These factors also had a significant impact on consumption behavior. This indicates that consumers not only care about health but also pay close attention to product quality and w88 win accuracy of related information.
• Subjective norms and price: These two factors had a lower level of influence but still played an important role in shaping decisions to consume fresh produce. This implies that social factors and price remain important considerations.
• Product availability: w88 win results showed that this factor did not have a direct impact on w88 win consumption of fresh produce, which could be due to w88 win fact that consumers in Ho Chi Minh City have been able to access fresh produce through various channels. However, this could also be a point for further research.
• Demographic characteristics: Differences in consumption behavior based on gender, age, education, and income were also an important finding, suggesting that different consumer groups have different motivations and priorities when purchasing fresh produce.

5.2. Managerial implications

Based on w88 win findings and discussions above, this study proposes several managerial implications:

• Strengthening health benefit communication: Businesses operating in w88 win fresh produce sector should focus on clearly, detailed, and credibly communicating w88 win health benefits of fresh produce. Diverse communication channels such as advertising, social media, and partnerships with nutrition experts should be utilized.
• Ensuring product quality and traceability: Providing high-quality fresh produce with traceable origins is crucial for building consumer trust. Businesses need to invest in rigorous production processes and quality control.
• Enhancing information credibility: Businesses should be transparent about their production processes, quality testing, and certification. Collaborating with reputable organizations to verify product quality is also an effective solution.
• Considering pricing: Businesses should set reasonable prices that align with consumers' purchasing power while considering promotions and discounts to attract customers.
• Focusing on target customer segments: Marketing and communication strategies should be tailored to different target segments based on gender, age, education, and income.
• Expanding distribution channels: Although availability is not a direct influencing factor, businesses should still maintain and expand distribution channels to ensure easy access to fresh produce for consumers.
• Deeper research on differences: Further research is needed into w88 win differences in fresh produce consumption behavior among different consumer groups, especially those with distinct perceptions and consumption behaviors.

These managerial implications can assist businesses and policymakers in making effective decisions to promote fresh produce consumption and contribute to sustainable development.
