通过对河南鄢陵花卉产业集群91户农户和46家企业的调查，用社会网络分析法揭示了农业创新系统由创新主体、网络和内容三部分构成，发现外地企业主导集群创新，政府直接作用较小，而企业与高校、科研院所紧密联系能显著提升创新能力。
This paper constructs the theoretical framework of agricultural innovation system,through field survey of 91 households and 46 agricultural enterprises in flower and plant industrial cluster in Yanling County,Henan Province,using social network analysis to conduct an empirical analysis on the structure of agricultural innovation system.It is found that,agricultural innovation system is composed of three parts of innovation subject,innovation networks and innovative contents.Enterprises in other regions play a leading role in agricultural cluster innovation;Higher heterogeneity of the status of innovation in local enterprises;the direct role of government in the innovation of agricultural clusters is smaller,but close linkages between enterprises,universities and research institutes can significantly improve the innovation capacity of cluster enterprises.Relative to the cooperative networks,knowledge networks show a multi-core structure and the centralization and density of the networks are higher.Compared with the manufacturing clusters,agricultural innovation is more dependent on the enterprises in other regions,market demands and the linkages between local enterprises,universities and research institutes.
