Abstract  

Transgenic maize is the second largest transgenic crop in the world and plays an important role in protecting human energy and feed industry. By using the method of patent analysis, this paper makes a statistical research on the patent documents from PatSnap database in the field of genetically modified maize in 1985-2016, the results showed the overall development trend of the global maize patents, the technology distribution and the research hot spot. A comparative analysis of the competitiveness of China’s maize research and development was also carried out. The future of maize industry development was finally put forward.

Key words： Transgenic maize      Patent      Information analysis
