通过数据包络分析方法(DEA),从总体效率、纯技术效率、规模收益和投影分析等方面研究了我国30个省区营林生产的投入产出效率。研究表明:我国营林生产长期投入不足,整体营林生产效率还处于较低的水平;DEA无效省区营林生产规模收益均处于规模效益递增阶段,营林绩效具有较大的提升空间。通过增加营林资本、技术投入与创新管理模式等手段可以有效提升营林生产的效率。
Through data envelopment analysis (DEA), the input-output efficiency of forest production in 30 provinces and autonomous regions in China was studied from the aspects of overall efficiency, pure technical efficiency, scale benefit and projection analysis. The results show that the long-term investment in forest management in our country is insufficient, and the overall forest production efficiency is still at a relatively low level. The scale returns of forest production in ineffective DEA are in the increasing stage of scale benefits, and the performance of forest management has more room for improvement. By increasing investment in forest resources, investment in technology and innovative management models, the efficiency of silviculture can be effectively improved.
