| With the further deepening of globalization mode,scientific development has also fallen into the bottleneck of development.The best way to deal with these problems is to deepen cooperation.In recent years,research institutions at home and abroad continue to strengthen cooperation in the field of science,which not only enhances the professional knowledge of their own researchers,improves the output of scientific research results,but also facilitates academic exchanges among scientific researchers around the world,thus forming a global exchange network.The continuous development of modern science promotes the rapid development of traditional agricultural science.Following the trend of the times,China actively supports the progress of agricultural scientific research.In addition to increasing the financial expenditure for agricultural scientific research,it also vigorously guides the innovation of agricultural scientific research institutions,and guides the production departments to further integrate agricultural scientific research technology and agricultural productivity.Similarly,the government has put forward higher requirements for the development of agricultural research institutions in China.The research object of this paper is the same as the research trend at home and abroad,that is,to analyze the cooperation of agricultural research institutions,and to study the cooperation of high-yield institutions with the most prominent productivity in the Yangtze River Delta.The cooperative papers of agricultural high-yield organizations in the Yangtze River Delta involve many agricultural related disciplines.The objective evaluation of the cooperation ability of the organizations is conducive to clear the right way of cooperation and improve the domestic and foreign competitiveness of agricultural organizations in the Yangtze River Delta.In this paper,two ESI discipline data of "agricultural science" and "plant and animal science" and four supplementary discipline data of "environment and ecology","Microbiology","biology and biochemistry" and "molecular biology and genetics" in 2009-2018 wos database are cleared up to determine the publications of agricultural institutions in the Yangtze River Delta region in the database.First of all,this paper makes a quantitative analysis on the distribution of high-yield organizations in the agricultural field in the Yangtze River Delta,and reveals the main characteristics of high-yield organizations' cooperative distribution from the perspectives of the overall output,the comparison of high-yield organizations' cooperative distribution,and the international cooperation mode.Secondly,this paper constructs the internal cooperation network,the domestic cooperation network and the international cooperation network of the high-yield organizations with the cooperation relationship as the connecting edge.In this paper,through the observation of each time period of three kinds of cooperation networks,the overall characteristic indexes,centrality and small groups of the networks in each stage are investigated,in order to reveal the cooperation between high-yield institutions and institutions in different regions in the field of agriculture and judge the institutions with high impact.After identifying the high impact organizations in the organization cooperation network,this paper analyzes the self-centered network of the high impact organizations and excavates the cooperation themes of each organization.Finally,this paper puts forward some suggestions for the cooperation of high-yield institutions,in order to promote the cooperation of institutions in the Yangtze River Delta and improve the competitiveness of institutions in the region.According to the statistical analysis,the author draws the following conclusions.(1)Through the econometric analysis of cooperative papers,it is found that the overall level of cooperative output of agricultural high-yield institutions in the Yangtze River Delta is high,but the influence of cooperative papers needs to be improved.In the Yangtze River Delta,the output of cooperative scientific research of high-yield institutions in the agricultural field is increasing year by year,and the cooperation of 2-4 main bodies is the large scale of output at present.The comparison of cooperative publications of various high-yield institutions shows that the dependence of foreign cooperation of high-yield institutions in the agricultural field is quite different,the cooperation rate of institutions ranking lower is higher,and the independent output capacity is weaker The international cooperation model of research institutions shows that the cooperation scale between high-yield institutions and developed countries,especially the United States,is larger.(2)Starting from the three types of cooperation networks of high-yield institutions,it is found that the frequency of cooperation between high-yield institutions is increasing,but the depth and breadth of cooperation between high-yield institutions and foreign institutions still need to be improved.Specifically,with the change of time,the cooperation frequency between high-yield institutions has been increasing,but the cooperation between high-yield institutions and domestic institutions is mostly limited to the cooperation with domestic top universities,and the high-frequency cooperation objects of high-yield institutions are mostly universities,with relatively few cooperation with foreign companies.It is found that Nanjing Agricultural University,Zhejiang University and Shanghai Jiaotong University have outstanding cooperative influence,and the three focus on different cooperative research themes.Nanjing Agricultural University pays more attention to the cooperation in the field of basic agronomy,while Zhejiang University has a relatively wide range of cooperation topics,with relatively more cooperation in molecular genetics and Biosciences,while Shanghai Jiaotong University focuses on chemical industry,veterinary science and other fields. |
