摘要
根据企业集群与生物种群的相似性,借鉴种群生态学中的竞争模型建立了企业集群模式下的企业之间竞争的数学模型。给出了时间尺度上此模型的持久性存在的充分条件:假设(H1),(H2)成立,则系统是持久的。研究结果表明,在外界对产品种群系统的增长起阻止的作用干预下,当产品种群系统内部增长率缓慢并且产品种群系统内部竞争力变强的情况下,hi(t),i=1,2越强对产品种群系统的持久性发展越有好处;而在合适的内部竞争和外部干预下,保持产品种群系统的自身的良好发展是企业集群保持持久性的关键。
According to some similarities between species population and enterprise cluster, and based on the competitive model of species population ecology, a competitive model of enterprise cluster with feedback control was established. Some sufficient condi- tions to ensure the permanence of the system is obtained： suppose that the condition （H1） and （H2） are fulfilled, then the system above is permanent. The present study showed that, when corporate products within groups of slower growth and enterprise com- petitiveness and external interventions on the population growth of enterprise products played a blocking role, hi （t）, i= 1, 2 is more better for the persistent development of enterprise and under the appropriate competition and external enterprise＇s own is crucial to maintaining persistence and an economic explanation to theoretical result is given.
