农业绿色全要素生产率增长及其影响因素

通过拓展的非径向非角度的DEA模型和Luenberger生产率指标，在估算了农业污染的前提下，计算了中国农业绿色TFP的增长，并对其影响因素进行了分析。结果表明：中国农业绿色TFP目前增长较慢，且区域差异明显；农业技术效率改善缓慢，技术进步是农业绿色TFP增长的主要源泉；如果忽视环境约束，将导致农业TFP增速的明显高估；农业税的减免促进了农业绿色TFP增速的提高，而农业财政支出的影响并不明显；工业化、城市化的推进和农业贸易条件阻碍了农业绿色TFP增速的提高。

China's Agricultural Green Total Factor Productivity Growth and Its Affecting Factors

With an extended non-radial and non-oriented DEA model and Luenberger index, this paper calculates China's agricultural green TFP growth, and analyzes its affecting factors on the basis of estimating agricultural pollutions. The results show, China's agricultural green TFP growth rate is low, and varies greatly among regions; Agricultural technical efficiency improves slowly, and technical progress is the main source of agricultural green TFP growth; If environmental restriction is ignored, the agricultural TFP growth rate will be overestimated significantly; Agricultural tax deduction facilitates agricultural green TFP growth, while fiscal expenditure plays an insignificant role; Industrialization, urbanization and trade terms hinders the growth of agricultural TFP.
