【摘要】 论文选取供给侧四大要素作为投入,产量作为产出,采用数据包络分析法计算了我国海水贝类产业的全要素生产率,幵将其分解为技术敁率及技术迚步,以浙江省为例分析了历年投入冗余及产出不足的情况。研究结果表明我国海水贝类产业2005-2014综合敁率平均值为0.816,在投入水平与技术水平既定的情况下产出仍有18.4%的增长潜力。沿海各省都有投入冗余的情况,其中以浙江省最为严重,主要原因是各要素的投入组合不合理,在现有的技术水平下投入过量,DEA无敁多由纯技术敁率无敁造成。2005-2014产业全要素生产率整体呈下降趋势,通过其分解得出结论——TFP下降的主要原因是技术退步。最后结合研究结论针对我国海水贝类产业实际情况从供给侧结极性改革的角度给出提升产业全要素生产率的建议。更多还原

【Abstract】 Based on the data envelopment analysis method,this paper selects the four elements of the supply side as input,and yield as output,total factor prod uctivity of marine shellfish industry in China was calculated,which is decomposed into technical efficiency and technical progress.The mean technical efficiency implying that production can be increased by 18.4% under current technology and input levels.While the average annual decline of the TFP from 2005 to 2014 mainly due to technological regress.Finally,recommendations to improve TFP was given from the perspective of the supply-side structural reforms according to the research conclusions.更多还原
