我国是世界范围内鸡蛋生产和消费的第一大国，鸡蛋也是我国居民膳食结构中主要的蛋白质来源之一，了解我国消费者对鸡蛋的偏好具有现实意义。本研究旨在了解中国消费者对鸡蛋的生产方式、认证标准和其他相关属性的偏好，以提供市场定位策略和科学依据，并为相关政策制定和饮食健康教育提供指导。问卷设计以离散选择实验设计为主体，结合对受访者相关食品安全知识的了解程度和人口学特征变量等数据的收集。最终课题组通过在线问卷平台收集到了全国30个省级行政区共1085份鸡蛋消费者样本数据，形成了2020年我国鸡蛋消费选择偏好数据集。数据集包括消费者鸡蛋消费过程中购买频率、购买来源，以及对鸡蛋价格、饲养方式、蛋鸡种类、食品安全认证属性的偏好等13个方面的内容。该数据集表明消费者对鸡蛋的生产方式、认证标准等属性有明确的偏好。这份数据集为我国禽蛋产品的消费偏好提供了基础数据，对于了解居民的消费习惯与偏好，保障国家食品安全，为食品企业制定市场策略，以及为政府科学制定决策提供了有力支持。

China, as the world's leading producer and consumer of eggs, relies significantly on eggs as a primary protein source in the dietary structure of its residents. Understanding consumer preferences for eggs in China holds substantial practical significance. This research aims to comprehend the preferences of Chinese consumers regarding egg production methods, certification standards, and other related attributes. The objective is to provide precise market positioning strategies, scientific foundations, and guidance for policymaking and dietary health education initiatives. The survey design primarily utilizes a discrete choice experiment (DCE) approach, supplemented by the collection of data on respondents' relevant food safety knowledge and demographic variables. Ultimately, the research team collected 1085 samples from consumers across 30 provincial-level administrative regions through an online questionnaire platform, forming the 2020 dataset on Chinese consumers' egg preferences. This dataset comprehensively encompasses 13 aspects, including the frequency and sources of egg purchases, as well as preferences for egg prices, rearing methods, hen breeds, and food safety certification attributes during the egg consumption process. The research findings reveal distinct consumer preferences concerning egg production methods and certification standards. This dataset serves as foundational information for understanding residents' consumption habits and preferences, ensuring national food safety, guiding market strategies for food enterprises, and providing robust support for evidence-based policymaking by the government.
