摘要
随着中国海水养殖产量的不断增长,由其带来的生态环境问题受到日益广泛的关注。本文运用SBM模型对2008-2016年中国海水养殖生态经济效率进行测度,并对导致生态经济效率损失的原因进行探讨。通过研究发现：2008—2016年中国海水养殖生态经济效率均值为0. 62,整体呈现出逐渐趋优态势,但还存在较大的提升空间。从海域分布来看,海水养殖生态经济效率的海域排名从高到低依次为：南海海域、黄渤海海域、东海海域。各沿海省份海水养殖生态经济效率存在明显的差距,且呈现出不同的波动趋势。导致海水养殖生态经济效率损失的原因主要集中于资源的过度消耗和过量的养殖产污,其中资源消耗指标中渔船投入、面积投入和培训投入以及养殖产污指标中氮污染产出过量的影响程度较高。提高资源利用效率,降低养殖环境污染是海水养殖生态经济效率改善的主要方向。
With the continuous increase of mariculture production in China,the ecological environment problems caused by mariculture have received widespread attention. In this paper,SBM model is used to measure the eco-economic efficiency of mariculture in China in 2008-2016,and the causes that lead to the loss of eco-economic efficiency are also discussed. Research reveals：（1） In 2008-2016,the average value of eco-economic efficiency of China＇s mariculture was 0.62. The overall trend is gradually improving,but there is still a large room for improvement.（2） In terms of the distribution of marine areas,the eco-economic efficiency of mariculture is ranked as high to low in order： South China Sea,Yellow Sea and Bohai Sea,and East China Sea.（3） There are significant differences in the eco-economic efficiency of mariculture in every coastal province which presents different fluctuation trends.（ 4） Reasons leading to the mariculture eco-economic efficiency loss mainly limited to excessive consumption of resources and excessive aquaculture production and pollution. Among them,the influence of fishing vessel input,area input,and training input in the resource consumption index and the excess output of nitrogen pollution in the aquaculture pollution index are relatively higher. Raising the efficiency of resource utilization and reducing the pollution of breeding environment are the main directions of improving the eco-economic efficiency of China＇s mariculture.
