Overview

Quantitative analysis models monopolisation in the agricultural market, indicating critical transition points for intervention.

Key Points

  • This research aims to model monopoly formation in the agricultural market using percolation approaches for better forecasting.
  • Developed a two-dimensional percolation model of the agricultural market.
  • Conducted numerical experiments in a 200×200 domain to assess concentration dynamics.
  • Analyzed Ukrainian agricultural data from 2017-2023 to identify critical thresholds for monopolisation.
  • Identified a critical percolation threshold at P* = 0.59 for market monopolisation.
  • Observed a decline in the number of agricultural enterprises from 40.7 to 30 thousand (-26%).
  • Average land per enterprise increased from 490 to 576 ha, indicating concentration intensification.
