Risk Transmission and Influencing Factors of Guarantee Network of Urban Investment Platform
Financial stability is an important component of national security. Ensuring financial stability and pre-venting systemic financial risks are critical for the healthy development of China's financial industry. This paper employs social network analysis to examine the guarantee data from province X's urban investment platform,cov-ering the period from 2011 to 2023. We construct the guarantee network,explore its topological characteristics,and identify systematically important institutions. Using QAP regression analysis,we verify the factors influencing guaranteeing behavior. The results indicate that the guarantee network of province X's urban investment platform exhibits small-world characteristics,suggesting potential risks within guarantee relationships. Variations in degree centrality and the presence of structural holes positively influence guarantee relationships,while similarities in en-terprise registration locations and industries also have a positive effect. In contrast,differences in enterprise nature negatively impact guarantee relationships.
