摘要
渔业是粮食供应链中的一个重要组成部分,研究渔业经济效率,了解渔业资源开发利用的现状和问题,对于提高渔业经济效益、促进可持续发展具有重要意义。本文基于2012—2021年长江经济带11个省(市)的面板数据,结合超效率SBM模型、超效率Malmquist指数、泰尔指数分析法解析渔业经济效率时及其差异。结果表明,长江经济带渔业经济效率总体上不断上升,逐渐呈现出下游效率最高的变化态势;渔业经济效率值趋于1,各地对于渔业投入资源的利用率较高;渔业总体发展较为均衡,渔业经济效率的差异主要由区域内的差异形成。基于此,未来长江经济带的渔业发展要注重养殖渔业技术创新、养殖规模扩大化以及区域间的协调均衡发展。
Fishery is an important component of the food supply chain.It is important to study the economic efficiency of fishery and to understand the current situation and problems in the exploitation of fishery resources in order to improve the economic efficiency of fishery and promote sustainable development.Based on the panel data of 11 provinces(cities)in the Yangtze River Economic Zone from 2012 to 2021,this paper analyzed the economic efficiency of fishery and its differences when combining the super-efficient SBM model,super-efficient Malmquist index and Theil index analysis.The results showed that,the economic efficiency of the fishery industry in the Yangtze River Economic Zone had been increasing in general,gradually showing a trend of the highest efficiency in the downstream;the economic efficiency value of the fishery industry tended to be 1,and the utilization rate of fishery input resources was high in each region;the overall development of the fishery industry was relatively balanced,and the differences in the economic efficiency of the fishery industry were mainly formed by the intra-regional differences.Based on this,the future development of fishery in the Yangtze River Economic Zone should focus on technological innovation in aquaculture fishery,expansion of aquaculture scale and coordinated and balanced development between regions.
