| 中文摘要: |
| 在对2011要2012 年城郊与农区蔬菜投入产出效率进行比较分析的基础上，利用VAR 模型对1998—2012 年城郊蔬菜投入产出关系进行协整检验、脉冲响应和方差分解。比较分析表明：城郊蔬菜投入产出效益在下降，农区投入产出效益在增加：实证分析表明，蔬菜种植人工成本与物质费用均和蔬菜收益存在长期稳定关系，但蔬菜种植收益自身存在一定滞后效应，其次是物质费用，人工成本影响最小。完善蔬菜投入保障机制、提高农民素质和创新能力、加大技术投入是改善城郊蔬菜投入产出关系的重要手段。 |
| 英文摘要: |
| Based on the comparative analysis between suburban and rural vegetables in 2011-2012, the input-output relationship of suburban vegetable from 1998 to 2012 was analyzed using cointegration test, impulse response function and variance decomposition. The comparative analysis showed that: suburban vegetable input-output efficiency was in decline,
rural vegetable input-output efficiency was rised; The empirical analysis shows that: vegetable planting labor costs and
material costs existed long-term stable relationship with vegetable yields, but the vegetable yield itself had a certain lag effect, the second was material cost, the last was labor cost. So establish and improve the safeguard mechanism, enhance the quality and innovation ability , increase the technical inputs are important measures to improve the relations between input and output of suburban vegetable. |
