A spatial analysis of growth and convergence in Italian provinces: the role of road infrastructure
研究了1960年代意大利高速公路投资对南北经济差距的影响，发现投资虽显著但未能阻止南北极化，可能因南方投资不足未能缩小与中北部的可达性差距。
A spatial analysis of growth and convergence in Italian provinces: the role of road infrastructure. Regional Studies. The role of road infrastructure in reducing economic disparities is debated in both Europe and the United States. During the 1960s, huge investments in highways significantly reduced the time run between north and south Italy. A spatial analysis of convergence is performed. Results show that the effect of road infrastructure investment was significant but accompanied by a strong polarization between north and south (also emerging from non-parametric analysis) that it failed to prevent, possibly because investment in the south was not large enough to close the accessibility gap with the centre–north, a gap that appears to persist during the subsequent years.
