摘要
量化中国对虾类产品出口贸易的灰水足迹,探寻对虾养殖业的绿色发展途径,为对虾类产品出口贸易政策调整提供参考。构建出口产品的灰水足迹测算方法,采用多元线性回归模型,分析中国对虾类产品出口贸易灰水足迹的影响因素。结果表明,中国对虾类产品出口的灰水足迹受到对虾类产品出口总额、对虾类产品结构与对虾养殖产业结构的综合影响。其中对虾类产品出口额对总对虾出口的灰水足迹呈现正效应,产品结构和产业结构则呈现负效应。为促进中国对虾生产和贸易灰水足迹的下降,提出扩大对虾类产品的进口规模、提高虾仁类产品的出口比重、转变对虾养殖方式和重视养殖尾水达标排放等建议,以期实现中国对虾出口贸易灰水足迹进一步下降的目的。
To explore the green development path of prawn aquaculture industry and provide reference for adjusting the export trade policy of prawn in China,this paper quantifies the grey water footprint of China’s export of prawn products.The method of calculating the grey water footprint of prawn export products was constructed.The influencing factors of the grey trade footprint of prawn exportation in China was analyzed by multiple regression models.The research results showed that the grey water footprint of prawn exportation in China was affected by the total value of prawn exportation,the structure of shrimp products and the industrial structure of prawn aquaculture.It is concluded that the export value of prawn products has positive effects on the grey water footprint of total prawn exports,while the product structure and industrial structure has negative effects.The suggestions are made from the following aspects:enhancing the import scale of prawn products,adjusting the proportion of exports of prawn products,improving the prawn aquaculture methods,and putting more emphasis on aquaculture water discharge standards.
