Abstract: To prevent and respond supply chain risks in automobile manufacturing industry, a supply chain risks evaluation index system about automobile manufacturing industry is built from demand risks, supply risks, logistics risks and so on seven aspects based on supply chain typical structure in Chinese automobile manufacturing industry. The entropy weight theory is applied to combine with extension thought to establish an automobile manufacturing industry supply chain risks evaluation model based on entropy extension decision model. The classical and limited fields about supply chain risks and evaluation objects are identified. The steps and processes about supply chain risks evaluation are presented. Combined with supply chain risks data of JHQC、QRQC and XMQC three automobile manufacturing enterprises in A province, an empirical research is implemented. The results show that three enterprises’ supply chain risk levels are in I（lower risk level）, I（lower risk level） and II（low level） respectively. Overall speaking, the present situation is good, but XMQC automobile manufacturing enterprise’s supply chain risks have a worsened tendency. Index choice and model building is effective because of the correspondence between evaluate result and reality.

Key words: automobile manufacturing industry, supply chain risks, risk index system, entropy weight, extension decision, risk level
