中文摘要：

文章为研究企业社会责任对闭环供应链总体效率及决策行为的影响,考虑到多层多成员多目标决策的闭环供应链网络中同层非合作竞争决策者,以利润最大、排放废气最小、风险最小为目标,构建了由供应商、制造商、零售商、需求市场和回收商组成的超网络模型。该模型利用均衡理论及变分不等式的方法分析各层决策者的独立决策行为及其相互作用,并通过改进的投影梯度算法求得均衡点。通过三个算例分析得出企业社会责任水平对产品的交易平衡和价格水平的影响。

英文摘要：

Given the fact that in multilevel, multimember and multiobjective decision making closed loop supply chains network, it＇s the main target for the non-cooperative competitive decision makers in the same level to pursue maximum profits, minimise exhaust emmision and risks, to figture out the effects of corporate social responsibility for closed loop supply chains efficiency and decision making behaviours, this article constructs a super network prototype consisting of suppliers, manufacturers, retailers,demand markets and recyclers, which analying the independent decision making behaviours and interactions between decision makers in each level with the general equilibrium theory and variational inequality equation and obtaining the equilibrium by improved subgradient projection method. Finally it works out the effect of corporate social responsibility levels to the trade equilibrium and price level through three calculation analysis of samples.
