Characterization of Group Behavior of Corruption in Construction Projects Based on Contagion Mechanism

Abstract

With the rapid development of construction projects, more and more engineering corruption problems have emerged. Therefore, this paper proposes a SEIR (susceptible-exposed-infected-recovered) based corruption model to better understand the propagation process of corruption cases in construction projects. In this model, the data samples are collected from the 2018 Engineering Corruption Case Judgment Document, the propagation parameters are obtained through actual case analysis with the help of complex networks, the change process and key influencing factors of actual nodes in engineering corruption cases are simulated by Python. The study results indicate that the personnel conforms to the “4–9 transmission law,” in which the early stage is a period of high incidence of corruption cases. The network of corruption cases is somewhat vulnerable, and its spread is about minus 8 times the change in crackdown rate and 10 times the change in infection rate. The variation range of the susceptible population S and the removed person R in the propagation simulation curve can predict the relationship between corruption infection rate and crackdown rate, which can provide theoretical guidance for preventing the occurrence of corruption.

“…De acuerdo a Li et al (2022), la red de casos de corrupción es algo vulnerable y su propagación es aproximadamente menos 8 veces el cambio en la tasa de represión y 10 veces el cambio en la tasa de infección. El rango de variación de la población susceptible S y la persona eliminada R en la curva de simulación de propagación puede predecir la relación entre la tasa de infección por corrupción y la tasa de represión, lo que puede proporcionar una guía teórica para prevenir la corrupción.…”
