Self‐reinforcing Agglomerations? An Empirical Industry Study
利用结构计量模型检验内生集聚力的存在，以挪威海洋产业为例，发现该产业存在显著的规模经济，主要集中于九个细分行业中的子群，表明存在两个自我强化的集聚，但维系两者在一起的机制很少。
We test for the existence of endogenous agglomeration forces, using structural econometric models. After showing generally how to establish the existence of agglomeration forces empirically, we undertake an industry study of the maritime industry in Norway. The results suggest that there are significant economies of scale in the maritime industry. These economies of scale are mainly found in sub‐groups of a set of nine maritime industries. This indicates that the maritime industry consists of two self‐reinforcing agglomerations, but that there are few mechanisms actually keeping the two together.
