以1997—2009年间省繇时间序列一截面数据为基础，在方向性距离函数瓤共同边界分析架构下，测度考虑“坏产出”情况下的中国大陆地区31个省（市）农业生产的共同边界效率、群组边界效率以及达到整体理想最佳农业技术效率的追赶程度。主要结论如下：①1997-2009年间各省（市）共网边界农业技术效率呈现增加-减少-增加的变化趋势，其平均值为0．692,农业实际产出占理想产出的比例仅为69．2％；②不同群组农业技术效率存在明显差异，其地区分布与区域经济发展水平、农业生产条件存在着空间对应关系。即经济发展水平较高、农业生产条件较好的区域，技术效率和技术水平也较高。不同区域在环境管理中应实行差别化的管理政策；③东部和中部群组中大部分省份农业生产的共同技术bb率呈现增长的趋势，与最佳共同边界技术的差距逐步变小；而西部地区超过一半的省（市）出现了技术退步。

In this paper, the use of directional distance function along with the meta-frontier analysis is to explain the desired output of econometric development and the undesired output of pollution emission. Besides, the comparisons of the technology efficiency for the overall sample provinces and sub-group of the provinces are made. The comparisons of technical efficiency performance are computed for the difference between a specific province and a sub-group of the provinces and the meta-frontier technical efficiency that the specific province can capture up. The study finds that ： （ 1 ） The average value of agricultural meta-frontier environmental technology efficiency from 1997 to 2009 was 0. 692, indicating that in considering environmental factors, actual agricultural output accounted for about 69.2% of potential output. From the temporal perspective, in general agricultural environmental technical efficiency appeared a trend of increase-decrease-increase. （2） Sub-group efficiency were different among three sub-groups in China. Agricultural technical efficiency was related with regional economic development and agricultural production condition. Provinces with a higher level of economic development in eastern China have higher environmental technical efficiency, while provinces with a lower level of economic development in central and western China have lower environmental technical efficiency. Therefore, in different regions we should implement different agricultural and environmental management policies. （3） MGR grows in central China sub-group and eastern China sub-group; the gap with the best meta-frontier become smaller. And about half of provinces in western China had technical regress.
