Research On The Influencing Factors Of Supply Chain Information Sharing Effect From The Perspective Of Social Network Theory

Information sharing is a key component of supply chain management system.Its performance level affects the operation efficiency of supply chain management system,thus affecting the management level and management performance of enterprises.In view of how to improve the performance level of supply chain information sharing,many scholars at home and abroad have carried out research and discussion in this field.This paper attempts to introduce a new perspective of social network theory to study this proposition.Starting from the four dimensions of social network characteristics,i.e.connection strength,network density,network centrality and network size,this paper studies the influence of social network characteristics of supply chain network on the partnership and partner characteristics among members of supply chain network,and then clarifies the four dimensions of social network on the relationship between members of supply chain network and partners.The direct and indirect impact of information sharing performance.By exploring the social network factors affecting the information flow among supply chain network organizations,we can understand the relationship between the network characteristics of social network and the characteristics of supply chain partnerships and partners,as well as the effect of these factors on the information sharing of supply chain network.Thus,the core enterprises in the supply chain network can effectively manage and coordinate the whole supply chain network,effectively mobilize the resources in the supply chain network,effectively exert the advantages of the social network relationship of the supply chain,and provide positive practical guidance.Based on the theory of supply chain management and social network,this paper designs the questionnaire by referring to the mature research results at home and abroad,obtains the relevant data through the questionnaire,and boldly makes the corresponding research hypothesis on the basis of literature review.It uses SPSS22.0and AMOS22.0 software to calculate and test the relationship between variables,and obtains the interaction process between variables.The structural equation method is used to establish the model,which provides some preliminary guidance for the construction of social network structure of supply chain network and the improvement of information sharing performance.This paper analyses the impact of the strength of social network characteristics,network density,network centrality and network size on partnership,partner characteristics and the effect of information sharing,and studies the relationship among these variables.Then,on the basis of the conclusions drawn from the empirical research data,the hypothesis is validated,and some improvements and optimization are made to the model.Then,from the classical evaluation indexes of structural equation,the good degree of model fitting is discussed.The results show that in the supply chain organization,the strength,network density,network centrality and network size have a positive impact on the characteristics of partnerships and partners;the strength,network density and network centrality also have a positive impact on the effect of information sharing,but the direct impact of network size on the effect of information sharing is not significant.Good and stable partnership in supply chain has a positive impact on the information sharing effect of supply chain.At the same time,the partnership characteristics of enterprises in supply chain also have a positive impact on the partnership.The characteristics of supply chain partners with high similarity and complementary resources also have a positive role in promoting the effect of information sharing in supply chain.In the practice of supply chain management and operation,managers and enterprises need to rationally analyze the situation according to the different external environment,and then choose reasonable strategies that are in line with the actual situation,actively and effectively adjust the network characteristics and network structure of the social network of the whole supply chain to improve the level of information sharing of the whole network and promote supply chain management in China.Improve the level of rationality and economic efficiency.
