As emerging platforms and key drivers of high-quality agricultural development，agricultural science and technology parks play a profound role in promoting farmers’ income growth and advancing urban-rural integration.This study introduces the “Triple Helix” theory and resource orchestration theory to elucidate the theoretical logic through which national agricultural science and technology parks drive high-quality agricultural development.Through a multi-case study approach，the paper explores specific practical endeavors within national agricultural science and technology parks.The findings reveal that agricultural science and technology parks serve as important carriers for promoting high-quality agricultural development.The practices observed in the three cases demonstrate that national agricultural science and technology parks，guided by science and technology，facilitate synergistic innovation through the “trinity” collaboration of government，enterprises，and academic/research institutions.These parks integrate and concentrate various resource elements to serve the goals of high-quality agricultural development.A dual approach of technological and institutional innovation fosters a virtuous cycle of results transformation and value enhancement.It is recommended to strengthen government planning and institutional support，build multi-stakeholder coordination mechanisms，deepen the integration of production，education，research，and application，promote innovation in agricultural business models and formats，and bridge the gap between innovation and industrial chains.These measures aim to improve the supportive role of national agricultural science and technology parks in high-quality agricultural development and promote synergistic regional economic growth.
