史铁生人物形象创作的符号化

根据2003—2014年安徽渔业经济总产值、增加值及三次产业子产业相关数据，对安徽渔业经济发展状况进行分析计算。结果显示：安徽渔业第二、第三产业比重持续增加，第一产业对渔业经济贡献度虽然最高，但是贡献程度却呈下降趋势；水产养殖对第一产业的贡献度依旧最高，但也呈现出下降的趋势；水产品加工和水产运输为第二、第三产业中对渔业经济贡献程度最大的两个产业；Moore结构变化值和年均变动值均反映渔业产业结构发生巨大变化，产业结构超前系数显示第二、第三产业均超前发展，且第二产业超前程度远强于第三产业。并在此基础上，提出相应的对策建议。

Factors Influencing Fishery Economy and Change of the Industrial Structure: Taking Anhui Province as an Example

This paper studies the development of fishery economy of Anhui Province based on the output value, increased value and some relevant data of three sub industries and branch industries from 2003 to 2014. The results show that the ratio of secondary and tertiary industries increased continuously, and primary industry contributed most to fishery economy, but there appeared a downward tendency for its contribution; aquaculture contributed most to primary industry, but it also showed a tendency of decline; processing and transportation of aquatic products were the two biggest industries contributing most to fishery economy in secondary and tertiary industries; the values of Moore structure change and average annual change reflect that fishery industry structure underwent a great change; advance coefficient of the industrial structure indicates that secondary and tertiary industries developed much too fast and the former faster than the latter. Based on these findings, some suggestions are then put forward in the paper.
