Research on the Network Evolution Characteristics and Influencing Factors of Agricultural Patent Cooperation of Countries along"the Belt and Road"
As an important part of"the Belt and Road"initiative,agricultural science and technology cooperation is conducive to improving the scientific and technological level of countries along"the Belt and Road"and promoting mutual benefit and win-win results.Based on the agricultural patent data of 65 countries along"the Belt and Road"from 1990 to 2022,this paper uses the social network analysis to investigate the evolution characteristics of agricultural science and tech-nology cooperation networks of countries along"the Belt and Road",and empirically tests its influencing factors.The re-search results show that:①From the perspective of network evolution characteristics,the scale of the"the Belt and Road"agricultural patent cooperation network is still small.Nodes,ties,density and connectedness of the net work all show a trend of first rising significantly and then declining slightly,and the average distance continues to decline.In addition,the core countries in the network gradually change from"Russia,Israel"to"Russia,China,India,Israel,and Singapore";② The benchmark regression results indicate that the expansion of geographical distance,language distance,and industrial distance will reduce agricultural patent cooperation,while the expansion of economic distance and technological distance will promote agricultural patent cooperation;③From the perspective of heterogeneity analysis,expanding technological distance not only reduces agricultural patent cooperation between innovative countries and non-innovative countries,but also reduces agricul-tural patent cooperation between developed countries and developing countries;④Further analysis shows that the improve-ment of intellectual property protection level will enhance the inhibitory effect of language distance on agricultural patent co-operation,reduce the inhibitory effect of geographical distance and industrial distance on agricultural patent cooperation,and enhance the promoting effect of economic distance and technological distance on agricultural patent cooperation.The research conclusions of this paper can provide theoretical basis and policy guidance for promoting agricultural science and technology cooperation along"the Belt and Road".
