ANALYSIS ON THE AGRICULTURAI INDUSTRY'S CLUSTER COMPOSING ON LIFECYCLE STAGE AND EVOLVEMENT MECHANISM
研究了农业产业集群在形成过程中，通过流入效应、流出效应和乘数效应在不同生命周期阶段（孕育、成长、成熟）的演化机制，并提出了构建农业产业集群的建议。
In the gathering course of agricultural industry's cluster is finished and evolved from inflow effect,outflow effect and multiplier effect. At gestation stage in agricultural industry's cluster,the key element relying mainly on natural resources advantage is the foundation of inflow effect,the multiplier effect has not really fully functioned yet. During the course of pullulation,specialization and division of labour on the particular region are developed,and the multiplier effect plays a stronger role. The external large-scale economy by professional division of labour and area economy brought the new inflow effect for the pullulation stage. At maturity stage,cluster has already formed an intact industry value system,and the multiplier effect has fully functions. On the basis of original inflow effect,the innovative network based on the social capital is bringing the new inflow effect for the cluster. Should fully consider the characteristic of agricultural products and the natural endowment situation of local agricultural resource while constructing local agricultural industry's cluster .And also should develop leading enterprises energetically,encourage farmer to carve out. The government also should build the good external development environment for the development of agricultural industry's cluster.
