中文摘要:
      为探索制约林业科技成果转化的关键因素,了解当前林业推广现状、特征和存在的问题,结合二阶段DEA-HR模型和GIS对28个省(市、区)的林业推广效率及其参与主体的协调情况进行测算,分析林业推广服务效率与林业技术应用效率的时空变化,针对其协调情况进行了类别划分和评价。结果表明,林业推广服务效率为0.328~0.573,其中纯技术效率偏低;林业技术应用效率值在0.622以上,其中规模效率偏低。林业推广服务的高效率地区数量由7个增加到10个,林业技术应用的高效率地区数量由17个增加到2015年的25个。“协调且有效”的区域有13个,“协调且无效”的区域有3个,“不协调且有效”的区域有6个,“不协调且无效”的区域有6个。研究表明,林业推广服务效率低于林业技术应用效率,纯技术效率是制约林业推广服务效率的重要因素,规模效率是制约林业技术应用效率的重要因素;林业推广服务与林业技术应用两阶段效率在空间分布格局上呈现不同的变化,但高效率地区的数量均有所增加,呈现良好的发展态势;林业推广参与主体的协调类别呈现不同的分布特征,且不协调的原因各异,其中“协调且有效”的区域偏多,且分布呈集聚效应。
英文摘要:
      In order to explore the key factors restricting the transformation of scientific achievements and to understand the current situation, characteristics and existing problems of forestry promotion, this paper calculated the forestry extension efficiency and the coordination of their participating subjects from 28 provinces (cities, autonomous regions), combining the two-stage DEA-HR model and GIS, analyzed the spatial and temporal variation of the efficiency of forestry extension service and forestry technology application, and classified and evaluated its coordination. Results show that the maximum value of the forestry extension service efficiency is between 0.328-0.573 and the pure technical efficiency is low; while the forestry technology application efficiency is above 0.622, in which the scale efficiency is low. The number of high efficient areas for forestry extension services increased from 7 to 10, and the number for the forestry technology application increased from 17 to 25 in 2015. There were 13 “coordinated and effective” regions, 3 “coordinated and ineffective” regions, 6 “uncoordinated and effective” regions, and 6 “uncoordinated and ineffective” regions. This study also found that the efficiency of the forestry extension service is lower than that of the forestry technology application, in which the pure technical efficiency is an important restricting factor for forestry extension service efficiency and the scale efficiency is an important restricting factor for forestry technology application efficiency. The two-stage efficiency of forestry extension service and forestry technology application is different in spatial distribution patterns, but the number of high-efficiency regions has increased and the development trend is good. The coordination categories of forestry extension participants have different distribution characteristics, too, with different reasons for incoordination, among which the number of the “coordinated and effective” regions is bigger and the distribution also shows some agglomeration effects.
