Research on"Food and Gas Cycle"from the Perspective of Multi-subject Interests
Enhancing the cropland quality is an important foundation for guaranteeing food se-curity.The"food-gas-food"circular agriculture with bio-methane as a linkage has the effect of improving soil,saving resources and reducing the cost of growing food.This paper takes"food and gas cycle"practice as a typical case,on the basis of describing and summarizing the prac-tices and effectiveness of the"food and gas cycle"mode,under the perspective of multi-subject interests of governments,enterprises and farmers,building an analytical framework based on material flow chains,analysing the dynamics characteristics of participation in the"food and gas cycle"mode and interaction mechanisms among various subjects,exploring the possibilities and conditions for multiple subjects implemented the"food and gas cycle",and propose relevant suggestions.The research has two key findings,one is that environmental policy is the key impe-tus for local government attending the"food and gas cycle"mode,while the economic benefit is the key driver for farmers and bio-methane enterprises.The other is that"food and gas cycle"mode realize the common value goals of state,local governments,enterprises and farmers,by means of filling the short boards of the industrial chain,such as straw treatment,socialized serv-ices and clean energy supply,form a positive interaction among multiple subjects.
