Taking patsnap as the data source, a retrieval method was constructed by combining keywords with IPC classification number to carry out retrieval. After full and accurate inspection, the data were cleaned by combining IPC classification number with manual reading, and 9481 relevant patent documents were obtained. From the aspects of application trend, regional distribution, technology distribution and R & D subjects, the research on the development differences of straw energy utilization technology between China and foreign countries was carried out, and China's international competitive position in the field was analyzed from the perspective of patent portfolio theory.
