摘　　要：随着农业产业环境动荡性的不断加剧,市场经营者面临的生存压力日益加大。为应对激烈的市场竞争、扩大生存空间,龙头企业与农民合作社这两大新型农业经营主体在农业产业链中的关系发生着动态演化,逐步迈向“共生”时代。利用生物学共生理论,以“龙头企业+农民合作社+农户”的农业产业化组织模式为研究对象,将龙头企业与农民合作社之间的竞合关系纳入考量,构建二者之间的共生演化模型,分析共生演化模型的均衡点及其稳定条件,并对二者的共生演化过程进行仿真研究。研究表明:龙头企业与农民合作社的共生模式主要取决于各自的竞争与合作共生作用系数;对称互惠共生是最佳演化方向,是最稳定最有效率的共生模式。据此,政府及有关部门应通过治理竞合关系等途径,引导二者沿着有效路径向对称互惠共生模式演化。With the intensifying instability of the environment of agricultural industry,the survival pressure on market proprietors is dramatically increasing.To confront the fierce market competition and expand space for existence,the relationship in the agri-business chain between the two new subjects of agricultural operators of the leading enterprises and farmer cooperatives has evolved dynamically,gradually moving into the“symbiotic”age.Using the symbiotic theory in biology and taking the agri-business organization mode of“leading enterprises+farmer cooperatives+farmer household”as the research object,the paper takes into consideration the co-opetition relationship between the leading enterprises and farmer cooperatives,constructs a symbiotic evolution model between them.After analyzing the model equilibrium and its stability conditions,the paper also conducts a simulation study on the process of their symbiotic evolution.The results reveal that the symbiosis mode is hinged on the values of symbiosis coefficient,and symmetric reciprocal symbiosis is the best evolution direction and also the most stable and efficient symbiosis mode.Therefore,the government and departments concerned should optimize the environment of industrial symbiosis to guide leading enterprises and farmer cooperatives along an efficient path to evolving into a symmetric reciprocal symbiotic mode.
