Abstract: To improve the innovation of remanufacturing technology for enhancing the social recognition,the influence of original manufacturer's patent protection on technology innovation strategy of re-manufacturer was researched by using game theory.Based on the derivation of consumers demand function which included the level of technological innovation,the supply chain models which regarded to No-Technical-Innovation(NTI),no-patent-Technology-Innovation(TI) and Patent-Protect-Technology-Innovation(PTI) respectively were constructed and solved,and the performance of supply chain and the model preferences of members were analyzed in detail with theoretical analysis and numerical simulation methods.Our analysis showed that the level of technology innovation was always positively related to the cost savings of re-manufacturing and consumer's valuation of the re-manufactured products,the level of technology innovation under patent protection was lower than that without patent protection;when dealers carried out technology innovation,the original manufacturer's patent licensing fees were significantly higher and was negatively related to the R&D efficiency;the mode preference of re-manufacturer,green consumer and social welfare was ,the preference of the original manufacturer was ,and  the preferences of the supply chain system as well as the general consumers depended on the valuation degree of re-products from consumers.
