中国淡水养殖技术效率研究——基于2018年的数据

On evaluation of technical efficiency of freshwater aquaculture in China—Based on data from 2018

根据2018年中国淡水养殖地区统计数据,分析2018年中国淡水养殖技术效率水平。通过构建DEA模型,测算不同地区淡水养殖的效率值。结果表明:2018年中国整体淡水养殖技术效率较高,为0.85;不同地区的技术效率水平值存在差异,最高值为1.00,最低值为0.76。从空间分布看,7个区域的技术效率值不同,但没有明显区别,因此认为技术效率与空间分布无明显关系。基于研究结果,从技术创新、交流合作、产业结构等方面提出了相关建议,以期为中国淡水养殖效率研究提供可参考的资料。

According to the statistical data of China’s freshwater aquaculture areas in 2018,technical efficiency levels of China’s freshwater aquaculture in 2018 were analyzed.The DEA model was built to calculate the efficiency of freshwater aquaculture in different regions.The results showed that:in 2018,the overall efficiency of China’s freshwater aquaculture technology was relatively high,which was 0.85;the value of technical efficiency varied from region to region,with a maximum value of 1.00 and a minimum value of 0.76.From the perspective of spatial distribution,technical efficiency values of the seven regions were different,but there was no obvious difference.Therefore,it is believed that there is no obvious relationship between technical efficiency and spatial distribution.Based on research results,suggestions are put forward from the aspects of technological innovation,exchange and cooperation,industrial structure,etc.,in order to provide reference materials for the research on the efficiency of freshwater aquaculture in China.
