Abstract:The study selects 71 agricultural scientific research institutions in China as the object of information collection, based on their cooperation with one hundred countries and the agricultural geo-strategic pattern of countries along the “Belt and Road”, the mechanism and key areas and existing problems of international scientific and technological cooperation are analyzed. Research shows that there are eight scientific and technological cooperation models between Chinese agricultural research institutions and countries along the “Belt and Road”. The key areas are mainly their respective advantageous agricultural technology fields. There are such problems as unstable political and economic environment, insufficient funds, low team stability, focusing on form but ignoring project implementation, focusing on platform construction but ignoring solving practical problems, focusing on short-term benefits of cooperation but ignoring long-term strategic layout. Therefore, the study puts forward countermeasures and suggestions to promote high-quality agricultural science and technology cooperation between China and countries along the "Belt and Road". China can strengthen output of agricultural science and technology "soft power" through agricultural research institutions, focus on the development of huimin project, build a financial support system for international cooperation in agricultural science and technology, improve the government-research institution-enterprise cooperation model, and strengthen the construction of overseas agricultural talent teams, etc.
