Abstract: Intellectual property protection has become increasingly important during the R&D process of genetically modified crops. Its role has shifted from a defensive approach to a strategic tool, which has significantly affected innovation models of crops transgenic technology. Considering a certain order during the process of technology innovation which makes it a dynamic game, on the basis of Starkelberg Model and two key indicators of yields and profits, this paper analyzes the performance of original innovation and derivative innovation in the environment of industrial competition, and establishes models to devise formulas forinnovation performance calculation including yields, profit, etc. It concludes that intellectual property protection can directly affect innovation performance, thus affecting innovation models of crops transgenic technology based on case studies. Based on the strategic analysis of intellectual property protection, suggestions have been further brought up in this thesis to improve the policies of intellectual property protection on Crops Transgenic Technology.

Key words: crops transgenic technology, intellectual property protection, technology innovation model
