摘要/Abstract

摘要： 【目的】从投入产出角度分析超级稻种植过程中各生产环节的技术推广到位效率。【方法】通过对超级稻种植环节的分解，确立农业技术推广到位效率的关键指标，借助于超效率DEA方法对获取的第一手田间数据进行分析处理。【结果】超级稻示范户水稻生产效率都有效，非示范户的生产效率平均仅有80%；3个时间偏差指标对产量的总影响占15%；通过松弛变量分析，对于非有效指标的离差程度进行了分析和定量说明。【结论】超级稻推广环节的到位情况对超级稻的产量和效率有重要影响，研究充分说明农业技术推广的效率在种植管理中不仅影响到产量，也影响到种植成本。

Abstract: 【Objective】 This paper analyzes the efficiency of technology extension in super rice’s each production links from the angle of input and output. 【Method】 Through decomposing the planting links of super rice, using the first-hand field data and applying super-efficiency DEA method, the key indicators of agricultural technology extension efficiency were established. 【Result】The results show that the model household’s production was efficient, while the production efficiency of non-model household was only 80% in average. The three time deviation indexes accounted for 15% on yield of the total impact. Through analyzing the relaxation variables, the analysis and quantitative description of degree of deviation of the non-effective indexes was made. 【Conclusion】 The promotion situation of super rice has an important influence on its output and efficiency. This study fully explained that agricultural technology extension efficiency in growing management not only affects the output, but also affects the cost of planting.

Key words: super-efficiency DEA, extension efficiency, super rice, technology extension
