Place-based policy in southern Italy: evidence from a dose–response approach
评估了意大利南部一项区域政策（领土综合项目）的有效性，通过结合反事实设计和剂量反应函数，发现基础设施干预对目标地区（西西里）的工人数量和企业数量有积极影响，且资金强度与企业增长呈正相关。
This paper evaluates the effectiveness at a territorial level of a place-based policy for southern Italy, that is, territorial integrated projects (TIPs). We combine classical counterfactual designs and the construction of a dose–response function to assess the impact of the infrastructural interventions on the municipalities involved in a target region (Sicily). The results are robust enough to show policy effectiveness on both the number of workers and the number of plants. In the latter case, we also identify a significant and increasing dose–response function highlighting the positive relationship between funding intensity and the growth of plants.
