以辽宁省4个县200户农户为样本,运用DEA方法对林地投入产出经营效率进行测算,结果显示:样本户林地经营综合效率较低,综合效率均值为0.095,无效程度严重的占比为93.5%;样本户林地经营纯技术效率不高,纯技术效率总体均值为0.152,高达96%的样本户未实现技术有效;样本户林地经营规模效率较高,规模效率总体均值为0.810,实现规模有效的占比为45%。137个样本户林地经营处于规模报酬不变的状态,占比为68.5%。
Taking 200 households in 4 counties of Liaoning Province as samples, the DEA method was used to estimate the input-output management efficiency of woodland. The results showed that the overall efficiency of woodland sample management was lower, the comprehensive efficiency was 0.095, the proportion of ineffectiveness was 93.5% of the total sample. The pure technical efficiency of the sample households in forest management is not high, the overall average of purely technical efficiency is 0.152, and up to 96% of the sample households are not technically effective. The scale of operation of the sample households is relatively high and the overall average of scale efficiency is 0.810. The effective proportion is 45%. 137 samples of forest management in the state of scale returns unchanged, accounting for 68.5%.
