Structural change and economic development in Southern Italy
利用意大利多区域投入产出数据，测量南部工业结构细节及部门间联系，发现后向联系多样性与区域人均GDP正相关。
This article uses input‐output information to measure the detail of the industrial structure of the Italian South and the linkages between different industrial sectors. The basic hypothesis is that regional economic development will be associated with the variety of backward and forward linkages existing in a regional economy. This hypothesis is tested using linkage measures based on the concept of entropy applied to data from a multiregional input‐output system for Italy for five years between 1959 and 1975. The results show that levels of gross regional product and gross regional product per capita were higher in regions and years with diverse backward linkage measures.
