Abstract: With the rapid growth of technological innovation on graphene in the global world, graphene had become one of the critical and strategic emerging technologies in the international competition. In order to explore the technology evolution stage of graphene, an integrated method is introduced based on TRIZ and patent analysis. From the results of patent analysis, graphene technology experienced several inflection points, and entered into the rapid growth stage, and the related industries would face a number of business chances and the challenges of development and competition, meanwhile, the connected policies and strategies should be adjusted to meet the significant changes. Compared to the pattern of global graphene evolution, the innovation evolution pattern of Chinese graphene seems a little different. In order deeply analyzed the differences between China and global world, the evolutionary principles of TRIZ and non-linear analysis are utilized to this analytical framework. Finally, some police advices for the graphene industries development are proposed.

Key words: graphene, technology innovation evolution, patent analysis, TRIZ, law of promoting ideality degree
