中国近海捕捞渔业生产效率的实证研究——基于DEA-Malmquist指数方法

Empirical analysis of total factor productivity of offshore fishing in China—based on Malmquist index

利用2008—2013年近海捕捞渔业生产投入产出的面板数据,采用DEA-Malmquist指数方法对中国近海捕捞渔业全要素生产率的变动及构成进行了分析。结果表明:近海捕捞渔业平均全要素生产率呈增长趋势,年均增长率为2.3%,主要依靠技术进步来推动;技术效率变化与全要素生产率之间的同步系数为0.6,纯技术效率、规模效率与技术效率之间的异向变化导致技术效率的下降;天津、浙江、辽宁、海南、福建、广西等6个省市的全要素生产率呈增长趋势;沿海各省市近海捕捞渔业技术效率下降是平均纯技术效率下降和平均规模效率下降共同作用的结果。

This paper analyzed the inshore capture fishery TFP and its composition using the 2008—2013 panel data of inshore capture fishery input and output based on DEA-Malmquist index. The results showed that,during the study period,the average TFP of inshore capture fishery was growing trend,mainly relied on technological progress to promote,and with an average annual growth rate of 2. 3%. Synchronization coefficient of technical efficiency change and TFP was 0. 6,the relative fluctuation of pure technical efficiency change,scale efficiency change and technical efficiency change lead to the technical efficiency decline. The TFP of six provinces and cities,Tianjin,Zhejiang,Liaoning,Hainan,Fujian and Guangxi,showed growing trend. According to the evaluation index above,the decrease of technical efficiency change of coastal provinces inshore capture fishery due to the decrease of average pure technical efficiency change and average scale efficiency change.
