中国海洋经济投入产出表编制及产业关联效应

Input-Output Table Compilation and Industrial Linkage Relationship in China’s Maritime Economy

基于2002年、2007年、2012年、2017年和2020年全国投入产出表剥离出15个核心层海洋产业,构建了海洋经济投入产出表,测算海洋产业发展规模及对国民经济的贡献,揭示各海洋产业与陆域产业间的关联关系及动态变化趋势。研究表明;我国海洋经济向上发展的基本面没有改变,2020年产业规模较2002年增长近5倍,形成了以海洋旅游业为龙头的较稳定的产业发展格局;各海洋产业对陆域产业呈现“二>三>一”的基本依赖结构,且与陆域第三产业关联有逐步加深的趋势。

Based on the national input-output tables in 2002,2007,2012,2017 and 2020,the paper extracted 15 core marine industries,and constructed the input-output table of maritime economy.Then the research measured the development scale of marine industry and its contribution to national economy,and then revealed the linkage relationship and dynamic changing trend between marine industries and land-based industries.The results showed that,the upward development of China’s marine economy has kept the fundamentals,and the industrial scale in 2020 has increased nearly five times than that in 2002.Meanwhile,China’s marine economy has formed a relatively stable industrial development pattern,and the marine tourism industry has developed as the leading one.The basic dependency structure of marine industries on land-based industries showed the pattern of“secondary industry>third industry>primary industry”,and the linkage between marine industry and land-based third industry had a gradually deepening tendency.
