利用灰色关联分析方法,结合新的海洋经济核算标准,深入分析了山东省海陆产业关联程度。结果表明,山东省地区经济与陆地产业关联度高于海洋产业;海洋第一产业与陆地经济、陆地第一产业、陆地第三产业联系较弱,海洋第三产业与陆地第二产业联系较弱;山东省陆地经济与海洋科研教育管理服务业联系较弱。提出要以海岸带为纽带优化海陆产业联动发展布局,加强海陆产业内部的产业链对接,分阶段有重点地推进海陆产业联动发展。

英文摘要：

Shandong Province is an important coastal province of China. Shandong Peninsula Blue EconomicZone is the first national strategy zone that combines land and sea in China. Study on the marine-land industry com-bined development is very important. This article absorbs the results of previous studies and gives new understand-ing of the marine-land industry combined development. According to the latest data, the thesis used grey correlationanalysis method to analyze the correlation degree among the Shandong economy, the land industry and the marineindustry. The results show that the correlation degree between regional economy and land industry is higher thanthat of marine industry in Shandong Province. Ocean primary industry has weaker connections with land economy,land primary industry, and land tertiary industry. The correlation degree between ocean tertiary industry and landsecondary industry is relatively low. The industries of marine scientific research, education, management and serv-ice have weaker connections with land economy in Shandong Province. Finally the paper proposed that ShandongProvince should improve the marine-land industry combined development space layout by using coastal zone asbond, strengthen the industry chain docking between marine industry and land industry, promote the marine-landindustry combined development by carrying out different key tasks during different stage.
