Abstract: China's agriculture is large but not strong, and it is urgent to achieve a leap from a large agricultural country to an agricultural powerhouse. Digital technology is in the ascendant and has become a new driving force for promoting the development of the national economy. Accelerating the integration of digital technology and agriculture, and developing digital agriculture is an inevitable choice to help China's transition from a large agricultural country to an agricultural powerhouse. Based on the perspective of building a strong agricultural province, this study empirically examines the mechanism and promotion path of digital agriculture's impact on the achievement of the goal of building a strong agricultural country. Research has shown that digital agriculture has a U-shaped nonlinear impact on achieving the goal of building a strong agriculture. In addition to directly affecting the achievement of the goal of building a strong agriculture, digital agriculture also indirectly promotes the achievement of the goal of building a strong agriculture by promoting new agricultural business entities and the development of agricultural green industries. Financial support for agriculture is achieved by promoting the development of digital agriculture and empowering the construction of a strong agriculture. To achieve the goal of building a strong agriculture, we should vigorously develop digital agriculture and accelerate the construction of agricultural informatization; the development of digital agriculture requires continuous investment and long-term achievements. A scientific and reasonable digital agriculture investment mechanism should be established according to local conditions. Regions where digital agriculture plays a prominent role in promoting the goal of becoming a strong agricultural country should gradually introduce market mechanisms to promote high-quality development of digital agriculture. Other regions should increase financial support for digital agriculture, and the central government should provide special support for the development of digital agriculture in underdeveloped areas in central and western China; we should take the development of new agricultural business entities represented by farmers' professional cooperatives and agricultural green industries as the starting point, focus on promoting the development of agricultural green industries by new agricultural business entities, and improve the information technology level of their pre-production, production and post-production.
