For several years, the themes concerning agglomeration economies have been approached from different perspectives in the scientific debate, as capable of triggering various positive features. The present research starts precisely where many others arrive, that is, given the value of these externalities, analyzing the spatial distribution of the geographical concentration of economic activities and the related influencing factors. To this end, in this contribution an explanatory investigation is carried out into the spatial dynamics deriving from main productive sectors’ concentration in some Italian regions. The proposed methodological approach is based respectively on the LISA spatial autocorrelation models and on the analysis of non-neighboring clusters to understand if the geographical area of reference and / or the particular production sector are influencing variables. The empirical investigation confirms the presence of a parametric interaction between factors related in some cases on the geographical context and in others on the productive sector.

多年来，在科学辩论中，从不同角度探讨了关于集聚经济的主题，因为这些主题能够触发各种积极的特征。本研究正好从许多其他因素到达的地方开始，也就是说，考虑到这些外部性的价值，分析经济活动的地理集中度的空间分布及其相关的影响因素。为此，在此贡献中，对意大利某些地区主要生产部门集中的空间动态进行了解释性研究。所提出的方法论方法分别基于LISA空间自相关模型和非相邻集群的分析，以了解参考地理区域和/或特定生产部门是否正在影响变量。实证研究证实，在某些情况下与地理环境有关的因素与在其他情况下与生产部门有关的因素之间存在参数交互作用。
