Abstract:The organic combination of agricultural scientific and technological innovation and financial support is an important means to solve the problems of agriculture, rural areas and farmers. As a major agricultural province, Sichuan has witnessed rapid development of agricultural science and technology in recent years. At the same time, financing needs have shown an increasing trend. Although the support of regional finance to Sichuan's agricultural science and technology innovation is increasing, there are still problems such as insufficient financial support, investment structure to be adjusted, inactive market financing, imbalance between supply and demand, and imperfect risk sharing mechanism. Therefore, in view of the current situation and problems in the development of financial support for agricultural science and technology innovation in Sichuan, put forward relevant countermeasures and suggestions, and analyze the Sichuan agricultural science and technology innovation and financial support development model, namely: "policy input guidance + financial institution alliance" diversified subject input model; "government + guarantee + insurance + policy + financial institution" comprehensive risk protection model; "Financial instruments + services + platforms + multiple financing" integrated flexible capital market model.
