With the rapid development of information technology and economicglobalization, the competition between enterprises is more and more fierce, andthe relationship of the enterprises on supply chains becomes closer. In thesecircumstances, the traditional competitive mode between enterprises is graduallysubstituted by that new one between supply chains. At the same time, itscomplexity of structure and the increasing degree of coupling between of supplychains, make the occurrence frequency of disruption event higher. It is atremendous challenge that supply chain management must face to make timelyand effective strategies for dealing with disruption event. Disruption managementhas been the key topic of supply chain management.The dissertation is based on the above background. First of all, the domesticand foreign relevant literatures of this dissertation are analyzed from threeaspects: supply chain disruption management, competitive supply chain and spotmarket. On the basis of summary and analysis, the research contents of thisdissertation are put forward.Secondly, supply chain model which is composed by a single manufacturerand a single retailer is established, based on linear demand-price function, whichdiscloses the impact of disturbance time points and spot goods wholesale priceon retailers’ spot market strategy choice behavior.Moreover, the research is expanded into a model of spot market coordinatingsupply disruption based on supply chain competition. Through the comparisonbetween supply chain profits without spot market and supply chain profits withspot market, the different characteristics of spot market coordinating strategy’s performance in disparate situation are identified.Finally, the empirical analysis shows that the loss can be decreased but notremoved by spot market coordinating supply disruption after disruption event,which testifies the efficiency of spot market emergency replenishment strategy.
