Abstract: Technological innovation and patents are closely related to each other. From the perspective of patents, this paper mined and visually analyzed industry patent data from the dimensions of Jiangsu agricultural machinery manufacturing enterprises technology development trends, technology concentration, important applicants, and core inventors. The research showed that in the past ten years, Jiangsu agricultural machinery manufacturing enterprises have significantly improved their innovation abilities, with an average annual growth rate of 27.60% in patent authorization. Additionally, innovative agricultural machinery manufacturing enterprises have accelerated their development and growth, and the number of top 5 applicants in each subdivision accounted for an average of 72.27% of the total number of patents. Moreover, the innovation activity in subdivisions was uneven, and the innovation momentum was strong in 4 fields such as agricultural power machinery and general machinery. Finally, the industrywide invention patents accounted for only 942% of the total patents, which was obviously low, and the overall innovation level needed to be improved. Relevant research conclusions are helpful to comprehensively understand the status quo of innovation activities of Jiangsu agricultural machinery manufacturing enterprises and provide information support for scientific decisionmaking.
