Research on Key Core Technology Identification based on Patent Semantic Analysis: A Case of the Biological breeding field

To achieve high-quality development, China must break through key core technologies. Accurately identifying key core technologies is crucial for the government or enterprises to optimize their research and development layout and actively seize the technological high ground. This study used LDA semantic analysis to classify patents in the field of biology, and selected topics in the field of biological breeding based on topic keywords; Conduct a competitive analysis of two key core technologies: gene editing technology and plant transgenic technology. It is recommended to closely monitor the latest research and development progress in these two technologies by the world’s leading seed companies. Jointly with relevant entities, focus on tackling key core technologies, strengthen high-level open cooperation with domestic and international entities, accelerate the integration of informatics with biology, and promote the breakthrough of key core technologies in the field of biological breeding. These actions aim to provide decision support for the high-quality development of China’s biological breeding sector.
