This study sets up a spatial econometric framework to explore the factors that best describe land consumption in Italy at the municipal level. By modelling the different types of spatial interactions and geographical proximity between all Italian municipalities, the direct effects of land use drivers are assessed together with spillover effects. Land use data are drawn from the ISPRA-SNPA 82/18 Report and cover all 7,998 Italian municipalities. The results highlight the existence of endogenous and exogenous interaction effects and the crucial role of the demographic, socio-economic and institutional structure on land use intensity. Hence the need for a planning policy aimed at: i) strengthening institutional cooperation to deal with excessive administrative fragmentation; ii) improving institutional and governmental quality to trigger virtuous mechanisms for sustainable land use management.

本研究建立了一个空间计量经济学框架，以探索最能描述意大利市政层面土地消费的因素。通过对意大利所有城市之间不同类型的空间相互作用和地理邻近性进行建模，土地利用驱动因素的直接影响与溢出效应一起被评估。土地使用数据来自 ISPRA-SNPA 82/18 报告，涵盖意大利所有 7,998 个城市。结果强调了内生和外生相互作用效应的存在以及人口、社会经济和制度结构对土地利用强度的关键作用。因此，需要制定一项旨在：i ) 加强机构合作以应对过度行政分散化的规划政策；ii) 提高体制和政府质量，以启动可持续土地利用管理的良性机制。
