Abstract

The development of science and technology is one of the vital driving forces for the Chinese agricultural development. Based on 2,513 valid potato invention patents from 1986 to 2019 in China, a social network analysis is applied to investigate the effects of the network changes in potato patents on the innovation activities and potato production. The results show that China has formed a status quo of separation between potato-producing areas and patent-invention places. The collaborative relationships of potato patents are mainly distributed in non-main production areas. Most of the collaborations are intra-provincial rather than inter-provincial. The correlation relationship between potato innovation and potato yield is positive. But the density and cluster coefficients of collaborative networks in potato research affect the potato innovations differently. Considering the variation in collaborative networks and different technology progress in potato production across regions, a cross-regional exchange platform is needed to promote the dissemination and extension of potato patents in the main potato-producing areas.

中国的协作网络、技术进步和马铃薯生产

科技发展是中国农业发展的重要动力之一。基于中国1986年至2019年的2513件有效马铃薯发明专利，运用社会网络分析法研究马铃薯专利网络变化对创新活动和马铃薯生产的影响。结果表明，中国已形成马铃薯产区与专利发明地分离的现状。马铃薯专利合作关系主要分布在非主产区。大部分合作是省内合作而非省际合作。马铃薯创新与马铃薯产量的相关关系为正。但马铃薯研究合作网络的密度和集群系数对马铃薯创新的影响不同。考虑到各地区合作网络的差异和马铃薯生产技术进步的不同，需要建立一个跨地区的交流平台，以促进马铃薯专利在马铃薯主产区的传播和推广。
