The rice planting area in Neijiang City has remained stable at over 80 000.0 hm² annually, with a total output of approximately 670 000.0 t. In recent years, Neijiang has actively responded to national strategic initiatives, leveraging its regional geographic and climatic conditions, and taking Longchang County as the core production area to steadily promote the development of the ratoon rice industry, significantly improving resource utilization efficiency and economic benefits. This paper takes the ratoon rice industry in Neijiang City as research object, and on the basis of systematic reviewing its current development status, focuse on analyzing the connotative characteristics, operational mechanisms, and implementation outcomes of several typical new business models, including “leading enterprise+specialized cooperative+farmer”, “village collective economy+demonstration park+farmer”, “specialized cooperative+farmer” and “research institution+specialized cooperative+farmer”. It identifies existing issues in the industrialization process of ratoon rice, such as uneven regional adaptability, low standardization of cultivation and management techniques, insufficient integration of mechanization and agronomy, relatively loose interest linkage mechanisms, and limited industrial chain extension. Corresponding countermeasures are proposed from the perspectives of strengthening variety breeding and technology promotion, deepening the integration of agricultural machinery and agronomic practices, innovating and improving interest linkage mechanisms, extending the industrial chain and enhancing brand value, and reinforcing policy support and service guarantees. The aim is to promote high quality and sustainable development of the ratoon rice industry in Neijiang.
