The mud crab (), also known as the mangrove crab, thrives in shallow mangrove forests, subtidal zones, and muddy intertidal habitats. It is a highly valuable species in the mangroves and estuaries of tropical regions and is in high demand in Vietnam's coastal markets. This study provides a comprehensive analysis of the key factors influencing consumer behavior and purchasing decisions regarding mud crabs in Vietnam's three largest cities: Can Tho City, Ho Chi Minh City, and Hanoi Capital. To achieve this, the research employs rigorous analytical methods, including Cronbach's alpha reliability test, principal component analysis, and multivariate regression analysis, to identify the primary determinants of consumer behavior and purchasing preferences for fresh mud crabs. The multiple regression analysis reveals two key factors that significantly influence consumer choices: nutritional knowledge and convenience awareness. Most of consumers perceive fresh mud crabs as superior in quality, expecting them to offer greater freshness; higher levels of protein, amino acids, and minerals; as well as excellent flesh texture and enhanced palatability. Based on these findings, two strategic directions are proposed for the sustainable development of Vietnam's crab industry: (1) improving the nutritional quality of crab products to align with consumer expectations for health benefits and (2) enhancing the distribution network and diversifying product offerings to improve accessibility and convenience for consumers.
青蟹（又称红树林蟹）在浅海红树林、潮下带和泥泞的潮间带栖息地繁衍生息。它是热带地区红树林和河口的一种极具价值的物种，在越南沿海市场需求量很大。本研究全面分析了影响越南三大城市（芹苴市、胡志明市和河内市）消费者对青蟹的消费行为和购买决策的关键因素。为此，该研究采用了严格的分析方法，包括克朗巴哈系数信度检验、主成分分析和多元回归分析，以确定消费者对新鲜青蟹的消费行为和购买偏好的主要决定因素。多元回归分析揭示了两个显著影响消费者选择的关键因素：营养知识和便利意识。大多数消费者认为新鲜青蟹品质上乘，期望它们具有更高的新鲜度、更高水平的蛋白质、氨基酸和矿物质，以及出色的肉质和更好的适口性。基于这些发现，为越南蟹产业的可持续发展提出了两个战略方向：（1）提高蟹产品的营养质量，以符合消费者对健康益处的期望；（2）加强分销网络，使产品种类多样化，以提高消费者的可及性和便利性。
