国际社会对汶川地震的反应:外交慰问与灾难捐赠的影响因素分析(英文)
Supply chain coordination with buy back contract under risk constraints
【摘要】 以汶川地震后国际社会的反应为研究对象,分析研究了外交慰问、政府及非政府捐赠的影响因素.最小二乘法回归的结果表明,决定国际社会外交慰问顺序的影响因素有该国距离北京的距离、失业率与人均GDP.通过对国际社会对汶川地震捐赠额的影响因素进行分析,发现:①发达国家并没有提供更多的捐赠;②与中国贸易额越多的国家,其政府及非政府捐赠较多;③发展中国家更倾向于执行灾难外交策略以便提升其在中国的国家形象.
【Abstract】 The newsvendor problem is a basic model in studying supply chain coordination.However,most of the results are grounded on the assumption of risk-neutral agents.Rational decision makers in the real world both seek profit and reduce risk.The conception of supply chain coordination in the risk-neutral world was extended,the mean-variance analysis was introduced and the newsvendor problem was explored,which involves the coordination by buyback contracts under different risk constraints.The model indicates that decentralized supply chain has the function of diversifying risk in comparison with centralized supply chain.In addition,we simultaneously get the solution about wholesale price and buyback price,thus extend Choi’s model.
【Key words】 supply chain management; coordination; risk constraints; Pareto optimality; newsvendor model; buyback contract;
