The Influence Of Social Network Structure On The Performance Of Scientific And Technological Achievements Transformation

In the National Science and Technology Innovation Conference in 2016,Xi Jinping pointed out that science and technology innovation is not only researches in the laboratory,but must be transformed as a driving force for economic development.However,due to various reasons,such as policies,service systems and personnel incentives,the rate of Chinese scientific and technological achievements transformation is poor and the performance is unsatisfactory.As for a complex system,the transformation involves multiple organizations such as universities,enterprises and research institutions and the cooperation between different organizations constitutes a social network.Therefore,the study of relationships between structural characteristics of transformation network and individuals in it and the performance of scientific and technological achievements transformation has certain theoretical and practical significances.This thesis studies the impact of social networks on the performance of scientific and technological achievements transformation from two aspects: the individuals' structure characteristics and the overall structural characteristics.First,participation factors and cooperation models of scientific and technological achievements transformation is summarized.Then,according to the relevant data of the National Statistical Yearbook,the entropy method is used to calculate the weight and the transformation performance of university,enterprise and research institution is evaluated.After that,a random network is created to simulate the transformation of scientific and technological achievements,based on the theory of social network and innovation diffusion and reality data.Finally,through statistical analysis of the simulation results,conclusions are draw as follows: First,the degree centrality has an inverted U-shaped relationship with transformation performance of university and research institution,while closeness centrality is negatively correlated with it.This means individual's network centrality is not as high as much better for individual's structural characteristics have a greater impact on the transformation cost than on the transformation income.Second,the individual structural characteristics of social networks have a significant impact on university and research institution's transformation performance,and there is no significant correlation with enterprise's transformation performance.Third,for the overall performance of scientific and technological achievements transformation,the network average distance and centralization are negatively correlated with it,and the density is positively correlated with it.It means that the more unequal of status of transformation subjects and the farther the distance between them,the more unfavorable for improving the whole transformation performance.The more connections between different subjects,the more contribute to the transformation performance.On this basis,revelations and suggestions are put forward.
