基于灰色系统理论的广西海陆产业关联度分析

Grey Correlation Analysis on Marine and Land Industry of Guangxi Province

利用灰色关联度理论,对广西海陆产业的关联度进行了计算和分析,发现:1)北部湾地区工业基础薄弱,使得三次产业出现了比重"虚高"现象。目前海洋产业与陆域第一产业的关联度相对较高,海洋产业中第三产业比重较大。海洋相关产业由海洋经济的外围层发展成为海洋经济的支持层,产生了"角色颠倒"。2)海洋战略新兴产业与国民经济的关联度普遍较低,亟待发展。3)在全国主要沿海城市中海洋科研教育管理服务业与国民经济关联度水平广西最低。广西海洋科研教育服务业的发展速度落后于海洋各产业,亟待发展。

The correlation between marine and land industries of Guangxi Province is analyzed and calculated by means of grey correlation method based on the grey system theory.It is found that：1）The weak industry base in the Beibu Gulf of Guangxi Province makes the proportion of three industries ＂virtual high＂.At the present,the correlation between the marine industry and the first land industry is relatively high,and the proportion of the tertiary industry in the marine industries is higher.The industries related to the ocean have been developed from the perisphere to the support layer of marine economy,causing a ＂role reversal＂;2）The correlation between the marine strategic emerging industries and the national economy is generally lower and the former needs to develop urgently;3）The level of the correlation between the industry of marine scientific research,education,management and service and the national economy is the lowest in Guangxi Province compared with those in the main coastal cities of China.In Guangxi Province,The marine scientific research and education service industry falls,in developing speed,behind other marine industries and needs to develop urgently.
