Abstract:

Development of agricultural circular economy is vital for construction of Poyang Lake Ecoeconomic Zone.It aims at achieving the doublewin of economic efficiency and ecological efficiency of agricultural production.This article applied Data Envelopment Analysis (DEA) to evaluate the economic efficiency of agricultural circular economy,and adoptd ecological footprint of agricultural production to reflect the ecological efficiency of agricultural circular economy.For the purpose of evaluating simultaneously the economic efficiency and ecological efficiency of agricultural circular economy,a comprehensive index was introduced for evaluation of regional development of agricultural circular economy,and applied to Poyang Lake Ecoeconomic Zone.The result showed that the most areas faced the problems of pesticide and fertilizer input redundancy,low grain yield per hectare and high proportion of arable land and grassland footprints. It indicates that, in addition to spread the circular agricultural pattern of ‘Pigraising, Methanegenerating and Graingrowing’,the areas must adjust agricultural structure and develop other circular agricultural patterns such as ‘Pig/cattleraising,Methanegenerating and Fruit/fishinggrowing’.Thus in Poyang Lake Ecoeconomic Zone,the inputoutput efficiency of agricultural production will be improved and the ecological footprint of agricultural production will be lowered
