Abstract:

The international development trend of sugarcane technology was analyzed from the aspects of countries and number of patent applications, application institutions and technical differences, research and development hotspots, etc. The results showed that sugarcane technology patents presented three stages of slow growth, rapid growth and decline from 2000 to 2020. The most valued technology markets and major technology exporters in the world were China, the United States and Brazil, which had the largest accumulative patent applications. Large multinational companies such as Codihua, Bayer and Syngenta were not only the main patent applicants in the world, but also active in patent applications in China. They had applied for a large number of basic patents in the fields of sugarcane molecular breeding, asexual propagation, biochemical prevention and control, basically realizing global technical protection. The scientific research institutions and universities are the main body of domestic patent application, and patent type direction focuses on the research and development of sugarcane planting, production, processing and other new practical technologies.

Key words: sugarcane, patent, technology, intelligence, econometric analysis
