摘　　要：农业生产效率是农业综合生产能力的主要组成部分。广东现已进入现代农业建设全面推进阶段,农业生产效率的相关研究备受关注。本文应用基于数据包络分析(Data Envelopment Analysis,DEA)的时间窗分析方法,对广东省21个地市在1994～2007年间农业投入产出的效率进行了测算,并从横向(同一地区不同时间窗)和纵向(同一时间窗不同地区)两个方面对各地市农业发展的相对效率和动态趋势进行了对比分析和评价。结果表明,广东省农业发展的平均效率和稳定性存在较为明显的区域差距,珠三角地区农业投入产出的绩效相对最优,东西两翼农业生产的整体效率水平低于珠三角,但却处于较为稳定的发展状态。农业发展效率较差且随时间波动较大的地区主要集中在山区5个地市,其中清远的效率较其他地区低,韶关农业发展的波动性相对最为明显。研究结果可为深入了解农业投入产出绩效的整体情况和发展趋势提供参考,同时为相关管理部门制定有利于提高农业发展效率的政策措施等提供科学论据。Agricultural production efficiency is of the basis of comprehensive productive capacity of agriculture. Guangdong Province is now in promotion stage of modem agricultural development, which emphasizes agricultural production efficiency research. Using DEA （data envelopment analysis） theory, agricultural input-output efficiencies in 21 city-regions in Guangdong Province were calculated for 1994-2007. The relative efficiency and dynamic behavior of agricultural production were compared and evaluated laterally （i.e., the same region but at different time windows） and longitudinally （i.e., different regions at the same time window）. The results depicted some gaps in average agricultural productivity and dynamic stability among regions. Agricultural input-output performance of the Pearl River Delta was relatively optimal. Although the performance level in the ＂east-west double wings＂ region was less than that in the Pearl River Delta region, developmental trend in agricultural productivity in the ＂east-west double wings＂ was more stable. Regions of lower agricultural productivity and significant fluctuations were concentrated in the mountain areas of northem Guangdong. While the lowest agricultural productivity efficiency was in Qingyuan City, the highest variation in agricultural productivity was in Shaoguan City. The findings laid not only the basis for in-depth insight into provincial agricultural input-output efficiency and development trends, but also provided information basis for related departments to establish management policies that can enhance agricultural productivity.
