近年来中国汽车产业集群供应链体系发展日趋完善,反映出一定的类生物自调节性质,有必要从种群生态学角度对此展开研究。拟借鉴捕食者-食饵(寄主-寄生)理论,以Volterra模型为基础构建了三企业种群模型,仿真结果显示数值解图呈周期性变化,整个集群供应链体系趋于稳定发展。加强政府引导,合理分配资源及空间,在有效避免集群供应商恶性竞争的同时,可以推进集群供应链的整体稳定发展。
近年來中國汽車產業集群供應鏈體繫髮展日趨完善,反映齣一定的類生物自調節性質,有必要從種群生態學角度對此展開研究。擬藉鑒捕食者-食餌(寄主-寄生)理論,以Volterra模型為基礎構建瞭三企業種群模型,倣真結果顯示數值解圖呈週期性變化,整箇集群供應鏈體繫趨于穩定髮展。加彊政府引導,閤理分配資源及空間,在有效避免集群供應商噁性競爭的同時,可以推進集群供應鏈的整體穩定髮展。

By referring to the predator -prey ( host-parasitism ) theory , a three-enterprise species system was built based on Volterra model .The simulation results show that a periodic change is displayed on the numerical calculation chart , which demonstrates that the supply chain tends to develop steadily .It is accordingly proposed that governments should strengthen its guidance and reasonably allocate resources and space so as to prevent vicious competition .
