| 基于绿色全要素生产率视角，采用SBM-Global-Super模型对中国2000—2017年地级市农业绿色发展水平进行测度，运用Dagum基尼系数、σ收敛和β收敛方法考察农业绿色发展水平的地区差异和收敛性。结果表明:1)农业绿色发展水平表现出波动上升趋势，并存在明显的地区差异；东部地区农业绿色发展水平均属于领先型，其他地区分布相对分散；2)农业绿色发展水平的地区差异呈逐步上升态势，东北和中部区域内差异较小，东部—西部区域间差异最大；农业绿色发展水平的地区差异主要来源于区域间差异，超变密度和区域内差异的影响相对较小；3)全国及四大区域农业绿色发展水平并未呈现明显的σ收敛和绝对β收敛特征，但存在显著的条件β收敛趋势。 |

| Abstract: |
| Based on the perspective of green total factor productivity, this study uses the SBM-Global-Super model to measure the level of agricultural green development in the prefecture-level cities in China from 2000 to 2017. Dagum Gini coefficient, σ convergence and β convergence methods are adopted to investigate regional differences and convergence. The results showed that: Firstly, the level of agricultural green development shows a fluctuating upward trend, and there are obvious regional differences, the level of agricultural green development in the eastern region is the leading type, and the distribution in other regions is relatively scattered. Secondly, the regional differences in the level of agricultural green development are gradually increasing. The regional differences in the northeast and central are small, and the inter-regional differences between the east and the west is the largest. The differences in the level of agricultural green development mainly come from inter-regional differences, hypervariable density and regional differences are relatively small. Thirdly, the level of agricultural green development in the country and four major regions does not show obvious σ convergence and absolute β convergence characteristics, but there is a significant conditional β convergence trend. |
