Convergence and divergence across Italian regions

Abstract. This paper aims at showing the relevance of the Italian experience to the current debate on regional convergence. Regional convergence of per capita GDP in Italy is analyzed for the period 1953–1993 using the Theil coefficient of concentration and a relationship with the process of national economic development is postulated. Two different phases are distinguished, with 1975 serving as a break-point. Different kinds of disaggregation of regional inequality are attempted and a separation index for groups of regions is calculated. The general conclusion is that after a period of strong convergence, which was limited to the years 1960–1975, the process of regional convergence stopped in Italy and since then a long-term tendency towards divergence has been verified. Both the process of national development and spatial factors are shown to have played an important role in the convergence process, suggesting that the identification of appropriate temporal and spatial disaggregation is a necessary condition in order to understand the regional growth process.
