中国苹果主产区投入产出效率分析

The Input-output Efficiency Analysis of Apple in Major Production Areas of China

利用中国苹果主产区8个省份2001～2010年投入产出面板数据,运用数据包络分析(DEA)对其生产效率进行分析和评价。结果表明:除甘肃省与河北省外,苹果主产区生产效率维持较高水平,规模效率是地区间生产效率差异的主要原因,生产效率具有较强的地域聚集性和发展收敛性。通过对主产区10a间Malmquist值测算发现,主产区全要素生产率(TFP)在波动中小幅下降,其主导因素是技术进步的反方向发展;并在此基础上,提出了促进苹果主产区生产效率发展的合理对策建议。

The apple production efficiency using panel data of the eight major production areas of china during 2001～2010 were analyzed and evaluated.The results showed that in addition to Gansu Province and Hebei Province,the major apple production areas maintained a high level of production efficiency.Scale efficiency was the cause of inter-regional differences.Production efficiency had a strong geographical aggregation and convergence in the development.After estimating the Malmquist index during 10 years of the main production areas,we found that the total factor productivity（TFP） had declined slightly in the fluctuations.The dominant factor was the development of technological progress in the negative direction.On this basis,some policy and solution for the main apple producing areas to develop the total factor productivity were brought out.
