摘要: 基于数据包络分析方法对通辽市各旗县2000—2008年农业生产技术效率进行综合评价。结果表明:①通辽市农业生产技术效率整体上较低,但呈逐年上升的趋势。②通辽市各旗县农业生产技术效率的时空差异明显,霍林郭勒和开鲁县的农业生产技术效率表现为先降低后上升;库伦旗和科尔沁左翼中旗农业生产技术效率表现为持续上升;科尔沁左翼后旗、扎鲁特旗和奈曼旗的农业生产技术效率表现为随时间呈现一定波动性;各旗县中奈曼旗年均效率最高。③通辽市农业生产技术效率主要受投入冗余影响,各旗县均存在降水冗余,反映出当地农业生产投入的盲目性。降水的波动性和不确定性导致灌溉用水、耕地面积投入过多,进而影响了各旗县农业生产技术效率。不同旗县在不同年份的投入冗余有所差异,显示农民应对降水变动的措施也具有一定盲目性。建议针对气候的不确定性对农业生产的干扰展开研究,改进农业生产技术。

Abstract: Agricultural production technical efficiency in seven counties of Tongliao City from 2000 to 2008 was evaluated based on data envelopment analysis method. Results showed that:(1) The agricultural production technical efficiency in Tongliao City was generally low, but it increased continuously from 2000 to 2008. (2) The agricultural production technical efficiency was significantly different among the seven counties in both temporal and special dimensions. In Huolinguole and Kailu, the agricultural production technical efficiency decreased before 2004 and then increased after 2004. In Kulun and Horqin Left Wing Middle Banner, the agricultural production technical efficiency increased all along. In other counties, including Horqin Left Wing Rear Banner, Jarud Banner and Naiman Banner, the agricultural production technical efficiency had great fluctuations. (3) The agricultural production input redundancy, especially precipitation redundancy, had impacts on agricultural production technical efficiency in Tongliao City. To deal with the impact of the climate uncertainty, more and more irrigation water and irrigated land was input into agricultural production, which leaded to lower agricultural production technical efficiency. The agricultural production input redundancy is quite different among these counties. More attention should be paid on research of the influence of climate uncertainty on the agricultural production and the improvement of agricultural production technology.
