Overview

Analysis explores supply chain network changes, showcasing implications for economic resilience.

Key Points

  • The aim is to analyze the dynamics of supply chain networks at the firm level and their reorganization over time.
  • Utilized a dataset from Hungary covering 2014 to 2022 with over 711,000 companies
  • Reconstructed supply relations using monthly VAT data
  • Analyzed changes in supply-links and firm entries/exits annually
  • Developed a statistical network generation model to simulate SCN characteristics
  • Approximately 25% of firms exit the supply chain network annually
  • 28% of firms enter the network each year
  • 55% of supply-links in one year do not persist into the next
  • The average lifespan of a supply-link is about 13 months
  • The model accurately reproduces key characteristics of the Hungarian supply chain
