This paper provides an empirical analysis of the Italian total factor productivity (TFP) growth for the 1995-2012 period that takes into account the factors explaining cross-regional differences in productivity growth. We focus on the changes in the quality of labor caused by the increasing use of temporary workers and on the migration flows of human-capital, which almost unidirectionally moved from the Southern to the Northern-Centre regions. Empirical results provide evidence of a non-linearity (U-shaped) in the relationship between the use of temporary workers and TFP growth, which suggests that TFP growth in some Southern regions benefited from the increase in the share of temporary workers after the early 2000s, while regions in the Centre-North regions experienced an opposite effect, with the share of temporary workers being negatively related to TFP growth. Results also show that migration flows of qualified human capital had a positive impact on TFP growth in the regions of destinations, while the number of emigrants have a positive effect on the TFP growth in the regions of origin.

本文提供了1995-2012年期间意大利全要素生产率（TFP）增长的实证分析，其中考虑了解释生产率增长的跨地区差异的因素。我们着眼于临时工使用的增加引起的劳动质量的变化，以及人力资本的迁移，人力资本的迁移几乎是单方面地从南部地区转移到北部中心地区。实证结果提供了证据，证明临时工的使用与全要素生产率的增长之间存在非线性关系（U形），这表明一些南部地区的全要素生产率的增长得益于2000年代初以后临时工的份额增加，而中北部地区的效果则相反，临时工的比例与全要素生产率的增长负相关。结果还表明，合格人力资本的移民流动对目的地地区的全要素生产率增长产生积极影响，而移民人数对原产地地区的全要素生产率增长产生积极影响。
