Based on the selection effect, external effect, feedback effect and mutation effect, this paper builds up the cooperative competition evolution game under the condition of resource element complementary, risk profit sharing and collaborative multi-win, imitation copy evolution game under the condition of learning effect, spilling effect and assimilation effect, migration variation evolution model under the condition of function decay, layer transition and structure reorganization of logistic system's social network. By means of these models, this paper gives the network pathway of logistic system's social network extension, calculates the logistic system's social network capacity under the condition of limited bearing, designs the joint mediated degree to mark relationship strength and position strength. This paper tries to comprehensively prescribe the deepening pathway of logistic system based on social network, prove the deepening mode of logistic system based on social network, bring forth the deepening measure of logistic system based on social network.

By analyzing the game between up-stream enterprise's service aware and down-stream enterprise's service supply in supply chain under the condition of asymmetric information, this paper tries to build Bayesian game model between up-stream enterprise's service aware based on cost payment and down-stream enterprise's service supply based on value seeking, which is as similar as the game model between bargaining and auction. The paper also discusses the optimal cost payment decision of up-stream enterprise and the optimal value seeking decision of down-stream enterprise, so as to provide the condition tinder which up-stream enterprise's service aware and down-stream enterprise's service supply are both efficient, the condition under which down-stream enterprise can satisfy up-stream enterprise's service aware but it doesn't exceed expectant service value and doesn't get profit, and the condition under which the lowest service supply of down-stream enterprise can also satisfy up-stream enterprise's service aware. The paper proves that down-stream enterprise's service standard must be appropriately advanced, otherwise it will lead to sunk cost of service supply and more serious service competition, and that certain service aware cost of up-stream enterprise is necessary, but up-stream enterprise must consciously reduce try-and-error cost by means of externality effect, diffusion effect and spilling off effect of service in supply chain.
