Statistical data set of egg consumption preference survey in China in 2020

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.

中国是全球领先的鸡蛋生产国与消费国，鸡蛋在居民膳食结构中作为核心蛋白质来源占据重要地位。明晰中国消费者的鸡蛋消费偏好，具备极强的现实意义。本研究旨在探究中国消费者对鸡蛋生产方式、认证标准及其他相关属性的偏好，以期为精准市场定位策略制定、政策决策与膳食健康教育工作提供科学依据与实践指导。本次调研主要采用离散选择实验（Discrete Choice Experiment, DCE）方法，并辅以收集受访者的相关食品安全知识与人口统计变量数据。最终，研究团队通过在线问卷平台，从全国30个省级行政区的消费者中收集到1085份有效样本，构建了2020年中国消费者鸡蛋偏好数据集。该数据集全面涵盖13项维度，包括鸡蛋购买频率与购买来源，以及消费过程中对鸡蛋价格、养殖方式、蛋鸡品种与食品安全认证属性的偏好等内容。研究结果表明，消费者在鸡蛋生产方式与认证标准方面存在显著的偏好差异。本数据集可为掌握居民消费习惯与偏好、保障国家食品安全、指导食品企业市场策略制定，以及为政府开展循证决策提供坚实支撑。
