摘要:

运用DEA模型测度了2000~2010年黄淮海平原县域单元的农业综合效率,并将之分解为纯技术效率和规模效率,探讨农业效率的时空特征及其演变因素,为优化农业生产要素组合,提高农业的投入产出效率提供参考。研究发现:① 综合效率总体上处于中低层次,存在着较大的区域差异,高效率县域多分布在城郊县,这可能与城郊县域多发展都市农业有关。② 研究时段总体上下波动明显,无增长趋势;变异系数在沿黄两岸的一些县域较大,其值在0.060以上。③ 综合效率受纯技术效率和规模效率共同作用。多数县域规模效率达到有效状态,且规模效率大于纯技术效率;纯技术效率对综合效率的影响及制约能力略强于规模效率。④ 纯技术效率较高的县域逐渐由东向西转移,城郊县的纯技术效率相对较高;纯技术效率较低的县域逐渐由北向南转移;纯技术效率一般的县域逐步转移至海河平原上游区域。⑤ 规模效率较高,且分布较为均衡。⑥ 黄淮海平原农业生产效率大多处于规模报酬递增阶段。

Abstract:

This article measured agricultural efficiency of the Huang-Huai-Hai Plain in 2000-2010 by using the method of data envelopment analysis(DEA).Then it classified the agricultural efficiency into pure technological efficiency and scale efficiency for exploring the spatial and temporal characteristics of the agricultural efficiency and its evolution factors. The results suggest that: 1) The overall efficiency on the whole is on medium and low level and there exists large regional differences with high efficiency county located in the suburban. This may be attributed to development of urban and suburban agriculture in these areas. 2) The overall study period fluctuated significantly and there is no growth trend coefficient of variation is larger in some of the county along the Huanghe River, reaching above 0.060. 3) Overall efficiency is influenced by the combined effect of pure technical efficiency and scale efficiency. Scale efficiency of most counties are efficient, with scale efficiency greater than pure technical efficiency. Pure technical efficiency of the overall efficiency is slightly stronger than the scale efficiency. 4) The counties with higher pure technical efficiency gradually shift from east to west, and in suburban the pure technical efficiency is relatively high. The counties of lower pure technical efficiency gradually transfer from north to south. The counties of general pure technical efficiency are gradually transferred to the upstream region of the Haihe Plain. 5) Scale efficiency is higher, and distributed in a balanced way. 6) Most of the efficiency of agricultural production is in the developmental stage of increased scale returns in the Huang-Huai-Hai Plain.

Key words: overall efficiency, pure technical efficiency, scale efficiency, spatial and temporal pattern, county, the Huang-Huai-Hai Plain
