渔业产业结构对渔业技术效率的影响——基于SFA的实证分析

The impact of Fishery structure on Fishery technical efficiency——an application of stochastic frontier approach

论文以2003-2015年我国27个省份的渔业经济数据为样本,借助SFA方法研究渔业产业结构对渔业技术效率的影响。实证结果表明,我国渔业技术效率整体处于较低水平,存在较大改进空间;内陆省份和沿海省份的渔业均处于规模报酬递减阶段;对内陆省份来说,当前其渔业三次结构现状不利于渔业技术效率的改善;对沿海省份来说,积极发展渔业二、三产业有利于其技术效率的改善。最后,提出了改善渔业技术效率是提高我国渔业发展效率的重要途径;优化渔业产业结构是改善我国渔业技术效率的有效措施;同时,须及时调整渔业生产结构以适应不断变化的渔业自然资源条件。

This paper specifies a Stochastic Production Frontier function and a technical inefficiency function to conduct an empirical analysis about the impact of Fishery industry structure on Fishery technical efficiency, the data during 2003-2015 of China＇s 27 provinces are the foundation of this paper. The empirical results show that, the overall technical efficiency of China＇s Fishery is at a low level and there exists great improvement space for it; Both the Fishery of the inland and coastal provinces are in the diminishing returns to scale; the current Fishery industry structure is not conducive to its technical efficiency for the inland provinces; the positive development of the second and third Fishery industry is conducive to the improvement for the coastal Fishery technical efficiency. That means, the improvement of Fishery technical efficiency is an important way for its transformation development; optimize the Fishery industry structure is an effective measure to improve the performance of China＇s Fishery; meanwhile, it is necessary to adjust the Fishery production structure timely to adapt the conditions of changing fishery nature resource.
