基于"蜂鸣-管道"模型的中国农业科技创新合作网络及其产出研究OACHSSCD

The coordinated innovation of agricultural science and technology is very important to improve the problems of the scarcity of major original frontier achievements,the low level of scientific and technological innovation performance,and the insufficient investment in agricultural science and technology.Therefore,based on the"buzzer-pipeline"model and the list of winners of the Shennong China Agricultural Science and Technology Award from 2012 to 2023,the agricultural science and technology innovation cooperation network of 31 provinces in China was constructed,and the short-term and long-term impacts of intra-regional cooperation and cross-regional cooperation and their interaction effects on the output of agricultural science and technology innovation were revealed through panel negative binomial regression analysis.The results show that in terms of network structure,the scale and closeness of China's agricultural science and technology innovation cooperation network are expanding,and the intra-regional cooperation and cross-regional cooperation are gradually accumulating and strengthening.In terms of regional differentiation,the spatial distribution of different regions and provinces in China's agricultural science and technology innovation cooperation network showed significant differences.In terms of the impact of cooperation network on the output of agricultural science and technology innovation,both intra-regional cooperation and cross-regional cooperation have a significant promoting effect,and there is a significant negative correlation between the interaction effect of the two and agricultural science and technology innovation,and the long-term impact of cross-regional cooperation is smaller than the short-term impact,and the long-term impact of intra-regional cooperation and interaction effect is greater than the short-term impact.
