分工与协作的多元化使得供应链成员间的关系呈现出网络化的趋势。为更合理地设计供应链网络,基于投入与产出的视角,利用柯布-道格拉斯函数,分析在资源优化配置条件下供应链资源投入成本与产出数量间的基本关系,在此基础上构建不同市场结构下的供应链网络竞争模型,指出竞争网络规模和供应链个体差异对网络均衡的影响。认为供应链网络规模的增加将导致供应链个体和供应链网络整体利润水平的降低,供应链个体转化能力的差异化却能缓解网络规模增加的不利。通过数值算例分析,验证所得出的结论。
分工與協作的多元化使得供應鏈成員間的關繫呈現齣網絡化的趨勢。為更閤理地設計供應鏈網絡,基于投入與產齣的視角,利用柯佈-道格拉斯函數,分析在資源優化配置條件下供應鏈資源投入成本與產齣數量間的基本關繫,在此基礎上構建不同市場結構下的供應鏈網絡競爭模型,指齣競爭網絡規模和供應鏈箇體差異對網絡均衡的影響。認為供應鏈網絡規模的增加將導緻供應鏈箇體和供應鏈網絡整體利潤水平的降低,供應鏈箇體轉化能力的差異化卻能緩解網絡規模增加的不利。通過數值算例分析,驗證所得齣的結論。

The diversification of labor division and cooperation,endows the competition between supply chains a networ-king trend.In order to better design the supply chain network,based on the perspective of input and output,under guid-ance of optimal resources allocation,Cobb Douglas function is used to analyze the basic relationship between cost and out-put and draw a conclusion that the optimal production and supply chain input are linear related.Based on the conclusion, the supply chain network competition model under different market structures is established,and the impact of network scale and individual differences on network equilibrium are analyzed.It is concluded that increasing network scale will lead to lower profit level for both overall network and individual supply chain,which is not conducive to the long-term develop-ment of the industry.However,the individual differences between supply chain transformation abilities can alleviate the negative effects of increasing network scale.Finally,numerical examples are used to verify the conclusion in theoretical a-nalysis.
