Neural-tube defects (NTDs) are considered to be the most common congenital malformations. As Shanxi Province, a poor region in the North of China, has one of the highest reported prevalence rates of NTDs in the world, folate fortification of rice is an excellent alternative to low intake of folate acid pills in this region. This paper investigates the relations between socio-demographic indicators, consumer characteristics (knowledge, consumer perceptions on benefits, risks, safety and price), willingness-to-accept and willingness-to-pay genetically modified (GM) rice. The consumer survey compromises 944 face-to-face interviews with rice consumers in Shanxi Province, China. Multivariate analyses consist of multinomial logistic regression and multiple regression. The results indicate that consumers generally are willing-to-accept GM rice, with an acceptance rate of 62.2%. Acceptance is influenced by objective knowledge and consumers' perceptions on benefits and risks. Willingness-to-pay GM rice is influenced by objective knowledge, risk perception and acceptance. Communication towards the use of GM rice should target mainly improving knowledge and consumers' perceptions on high-risk groups within Shanxi Province, in particular low educated women.
神经管缺陷（NTDs）被认为是最常见的先天畸形。作为中国北方的一个贫困省份，山西省的 NTD 报告发病率是世界上最高的之一，因此在该地区，强化大米叶酸是补充叶酸酸片的理想替代品。本文研究了社会人口统计学指标、消费者特征（知识、消费者对益处、风险、安全性和价格的看法）、接受意愿和支付意愿与转基因（GM）大米之间的关系。消费者调查由山西省 944 名面对面采访的大米消费者组成。多变量分析包括多项逻辑回归和多元回归。结果表明，消费者普遍愿意接受转基因大米，接受率为 62.2%。接受程度受客观知识和消费者对益处和风险的看法的影响。对转基因大米的支付意愿受客观知识、风险认知和接受程度的影响。针对使用 GM 大米的沟通应主要针对提高山西省内高风险群体（特别是低教育水平的女性）的知识和消费者认知。
