Abstract: This paper set biofortified iron-rich wheat as an example, applied cost benefit analysis and cost effectiveness analysis methods, detailed analyzed health benefit, total R&D cost and its construction, cost benefit ratio and cost-effectiveness, and made international comparision. The results showed that the nutrition intervention of the biofortified iron-rich wheat project of HarvestPlus-China was high cost-effective. The health benefit gained was 112 706~291 753 DALYs saved per year, implying that the economic benefit was 2.353 billion~6.091 billion yuan in 1 year after monetization, and 70.586 billion~182.719 billion yuan economic benefit over 30 years; HarvestPlus-China program  will put in total RMB 63.1492 million~94.1653 million yuan, in which the promoting cost accounted for almost 99%; the cost benefit ratio of biofortified iron-rich wheat project of HarvestPlus-China program was 1 117.76~1 940.41, implying that with RMB 1 yuan of investment, the iron-rich wheat project could gain benefit of RMB 1 117.76~1 940.41 yuan; according to the standards setting by World Bank and World Health Organization sepaerately, the biofortified iron-rich wheat project of HarvestPlus-China program was high cost-effectiveness on public nutrition intervention; the data from HarvestPlus program presented that in general the biofortification had an advantage of cost-effectiveness over food fortification and supplementation. In the end, a number of counter-measures proposed, such as increasing the investment in R&D to strengthen micronutrient content of biofortified crops, paying great attention to the biofortified crops' promotion and propaganda.
