制造企业物流业务自营与外包的经济分析

Economic Analysis of Logistics Operation by Itself and Outsourcingin Manufacturing Enterprise

通过引入物流业务外包比例λ这一变量来研究制造企业物流业务分别采用自营、外包以及两者共存的模式下制造企业和物流企业经济效益的变化。在建模过程中,综合考虑制造企业物流业务外包与自营的成本和收益,建立相应的数学模型,讨论在制造企业利润最大的情况下,产品销售价格与物流业务外包比例λ的关系,并分析的变化对制造企业产品销售价格、销售量、企业利润、物流企业利润,以及总利润造成的影响。通过经济学的比较静态分析得出随着λ的不断增大,制造企业的产品价格降低,销售量增加,企业利润增加,物流企业的利润也明显增加的结论。最后,通过实例验证了模型在理论上的合理性和正确性。

The influence on economic benefit under the condition of logistics operation by itself, outsourcing or both concomitant patterns in manufacturing enterprise was analyzed by introducing the logistics outsourcing proportion ）,. Considered the cost and income of logistics operation by itself and outsourcing in manufacturing enterprise, the corresponding mathematical model was set up.The relationship between product sale price and logistics outsoureing proportion ）, was discussed, and the influences of ;~ on selling price, sales volume of manufacturing enterprise, profit of manufacturing/logistics enterprise and total profit were analyzed on the condition of maximizing the manufacturing enterprise＇ s profit. It is concluded by using comparative static analysis that the increase of logistics outsourcing proportion has a positive effect on improving the benefit of the manufacturing enterprise and the logistics enterprise and reducing selling price. At last, theoretical correctness and rationality of the model was proved by an example.
