Abstract: [Objective] This paper analyzes the value, market demand and prospect development of Xiangfeng peony, and provides certain reference for introducing and popularizing this new variety, so as to promote the healthy development of Xiangfeng peony and oil peony enterprises and to ensure the sustainable development of oil peony industry.[Method] On the basis of existing research, the economic benefit evaluation index system of oil peony varieties, including yield per unit area, income per unit area, field management cost, investment recovery period, the increase rate of per capita income of planting farmers five evaluation indexes, is constructed. By determining the index weight based on AHP (analytic hierarchy process) in combination with Yaahp11.1 software and establishing the comprehensive benefit evaluation model with the fuzzy comprehensive evaluation method, this paper takes "Fengdan" original high quality varieties as control group, the economic benefit and evaluation of the original varieties of peony and "Xiangfeng" were analyzed.[Result] The result of this study indicated that the economic benefit evaluation result of "Xiangfeng" is "good", and the result of the economic benefit of "Fengdan" is "general". In terms of the yield per unit area, "Xiangfeng" compared with the original "Fengdan", and the yield per hectare increased by nearly 750 kg, which increased by 126.84%. In terms of the income per unit area, "Xiangfeng" increased its income per hectare by about 22 500 yuan. In the field management fee, "Xiangfeng" in the field management cost index is slightly lower than that of original "Fengdan"; In the investment recovery period, "Xiangfeng" can make both ends meet in the third year after planting, as early as one year in "Fengdan". This indicates that the new variety of "Xiangfeng" has been improved in economic efficiency, and its economic benefit is better than that of "Fengdan"[Conclusion] Compared with control group,the original varieties "Fengdan", "Xiangfeng" has good economic benefit. It has a positive impetus to the development of regional economy and farmers' incomes, the future development trend is good, the development potential is larger. The introduction of the new species will bring more economic benefits and profits. Therefore, the new variety of "Xiangfeng" has the value and potential of being widely promoted by enterprises and farmers.
