我国农业和农村经济已进入一个新的发展阶段,既面临“工业反哺农业、城市支持农村”的重大机遇,又面临资源、市场约束增强和体制、机制性矛盾凸现的严峻挑战。在这种形势下,要确保粮食稳定增产、农民持续增收和农村社会和谐发展,就必须始终坚持用科学发展观统领农业和农村经济? China’s agriculture and rural economy have entered a new stage of development. They not only face the great opportunity of “industry nurturing agriculture and cities supporting rural areas”, but also face the severe challenge of intensifying resource and market constraints and highlighting institutional and institutional contradictions. Under such circumstances, to ensure a steady increase in grain output, a steady increase in peasants’ income and the harmonious development of rural society, we must always insist on using the scientific concept of development to lead the agricultural and rural economy.
