摘要
Under the special background of China, the cooperative innovation between different Government-Industry-University-Research institutes plays an increasingly important role in the agricultural field. However, existing literature has paid little attention to it. Taking the cooperation patents published in agr iculture field from China Patent Full-text Database as study object, spatial attribute and institutional attribute of the authors as data source, combining social network analysis and spatial econometrics analysis, this paper analyzes the structure evolution characteristics of cooperative innovation networks of agricultural Government-Industry-University-Research institute in the city level of China in 1985-2014 based on the triple helix theory, with influence factors discussed. It shows that,(1) since 1985, China's agricultural innovation level has been substantially increased, but the development degree of cooperative innovation network is low and patent cooperation mainly relies on authors in the same unit;(2) enterprises play a leading role in agricultural cooperative innovation. The effect of the government and hybrid organizations driven by the government isn't obvious.(3) cooperative innovation in the province and the city dominates, Multi-pole pattern has been formed. The cooperative innovation network structure evolves from single helix empty core, double helix multicore to double helix hierarchical network;(4) science and education funding and personnel investment of the city are key factors determining agr icultural cooperative innovation, while agricultural development of the city have slight negative impacts on it. Spatial mismatch of supply and demand happens to technical cooperative innovation of China's agriculture. Therefore, strengthening science and education investment to big agricultural provinces allows of no delay.
