利用1985-2007年省际面板数据,基于DEA的非参数Malmquist指数法对农业全要素生产率进行测算和分解,并在此基础上对其进行收敛分析。测算结果表明,总体而言,1985-2007年我国农业全要素生产率呈现增长态势,其动力来源于农业技术进步;收敛分析结果表明,我国农业全要素生产率同时存在绝对β收敛和条件β收敛。
Agricultural Total factor productivity (TFP) was calculated and decomposed by non-parametric DEA Malmquist index method based on the provincial panel data from 1985 to 2007. On this basis, this paper has tested the convergence hypothesis of the agricultural TFP. The calculation results show that the agricultural TFP had been increasing from 1985 to 2007 primarily due to technical progress. The convergence analysis suggested that the unconditional β convergence and the conditional β convergence coexist in agricultural TFP.
