本文研究了意大利跨行业的空间集聚,通过使用控制的机会和工厂规模的影响的指标。1996年100个工业制造部门的数据表明,向心力大于离心力。计量经济学结果表明,集聚是由一个部门的人力资本密集度和创新倾向促进的,并受到运输成本的阻碍。因此,知识溢出效应更重要的行业往往更加聚集。运输成本的负面影响意味着贸易下降。
This paper investigates spatial agglomeration across industries in Italy, by using indexes controlling for the effects of chance and plants size. Data on 100 industrial manufacturing sectors in 1996 show that centripetal forces prevail over centrifugal ones. Econometric results show that agglomeration is fostered by both the human capital intensity of a sector and its propensity to innovate and hampered by transportation costs. Hence industries where knowledge spillovers matter more tend to be more agglomerated. The negative influence of transportation costs implies that falling trade.
