This article presents the results of a piece of research into extortion in the city of Palermo between 2004 and 2015. Highlighting the importance of the territorial context among the factors that explain the mafia phenomenon, the study draws on two different georeferencing databases: the first relating to the distribution of extortion across the Sicilian capital's various districts, and the second relating to the distribution of Palermo businesses that had joined the Addiopizzo anti-extortion movement. Although the empirical material is problematic, marked territorial variations emerge from a comparative analysis of the two databases, prompting a number of potential interpretations.

社会变革和反黑手党运动：“Addiopizzo”变量

本文介绍了 2004 年至 2015 年间对巴勒莫市敲诈勒索的一项研究结果。强调了地域背景在解释黑手党现象的因素中的重要性，该研究利用了两个不同的地理参考数据库：第一个与勒索在西西里首都各个地区的分布，第二个与加入 Addiopizzo 反勒索运动的巴勒莫企业的分布有关。尽管经验材料存在问题，但对两个数据库的比较分析出现了明显的地域差异，从而引发了许多潜在的解释。
