摘要
利用赫芬达尔-赫希曼指数、空间基尼系数、熵指数和地点系数对2001-2012年我国海洋产业集聚水平进行测度,结果表明我国海洋油气业、海洋矿业和海洋盐业的产业集聚水平最高;海洋渔业、海洋化工业和海洋电力业产业集聚化趋势明显;同时,海洋产业的集聚程度在不同沿海地区间差异较大;而影响海洋产业集聚的主要是区位因素、产业规模递增、产业波及效应和差异化竞争等因素。
This paper measures the agglomeration level of marine industries between 2001 and 2012 with the H index, spatial Gini coefficient, entropy index and location coefficient. The results show that the offshore oil and gas industry, marine mining industry and sea salt industry have the highest agglomeration level, while marine fishery industry, ma rine chemical industry and marine electric power industry follow the agglomeration trend obviously. Also, the agglom eration levels varies in the coastal areas, and the location factors, increasing returns to scale, industrial spread effect and differentiation competitive play important roles in effecting the agglomeration of marine industries.
