笔者采用樊福卓在2013年提出的产业结构相似指数测度方法,分别测度了我国11个沿海省市在海洋三次产业分类下和细分海洋产业分类下的海洋产业结构相似指数。研究结果表明,在不同海洋产业分类条件下,所得到的海洋产业结构相似指数呈现不同的变化趋势。具体表现为:在三次产业分类下海洋产业结构存在趋同现象,并且海洋产业同构问题较为严重,而在细分行业下海洋产业结构则表现为趋异,海洋产业结构相似指数较小,并不存在严重的同构问题。
The author uses the method of similarity index of industrial structure put forward by Fan Fuzhuo in 2013 and measures the similarity index of marine industrial structure under the classification of marine three industries and the classification of marine industries in 11 coastal provinces and cities respectively. The results show that under the conditions of different marine industry classification, the similarity index of the marine industrial structure shows different trends. The concrete manifestation is that the industrial structure of the oceans is converging under the three industrial categories, and the problem of isomorphic structure of the marine industries is more serious. However, under the sub-industries, the industrial structure of the oceans shows divergence and the similarity index of the marine industrial structure is small, There is a serious problem of isomorphism.
