生猪产业链的演化机理研究

摘要

生猪产业链是一个开放的系统，其演化过程具有远离平衡态、产生非线性、形成巨涨落等复杂适应性特征。生猪产业链的演化可分为三个阶段：非健康生猪产业链阶段、亚健康生猪产业链阶段和健康生猪产业链阶段，在生猪产业链演化的不同阶段，由于环境、组织及机制条件的不同，演化模式也不相同，非健康生猪产业链阶段的演化模式是在政府的主导下，非健康生猪产业链的转型模式；亚健康生猪产业链阶段的演化模式是在政府与龙头企业共同主导下亚健康生猪产业链的升级模式；趋于健康生猪产业链阶段的演化模式是在龙头集群企业主导下的健康养殖产业链优化模式。%Pig industry chain is an open system;its evolution is of complex adaptive features such as far from equilibrium, nonlin-ear generation and the giant fluctuation. Evolution of pig industry chain can be divided into three stages:unhealthy pig industry chain stage, sub-healthy pig industry chain stage and healthy pig industry chain stage;because in different stages of the pig industry chain e-volution, the environment, organization and mechanism conditions are different, the evolution patterns are also different. The evolution model for unhealthy pig industry chain stage is a transformation model which is under the guidance of the government;the evolution pat-tern for the sub-healthy pig industry chain stage is an upgrading model which is under the dominant of the government and enterprises;the evolution model for healthy pig industry chain stage is an optimization model which is controlled by the leading cluster enterprise.
