Effciency and productivity of conventional and organic farms in Finland 1994-1997
用数据包络分析比较芬兰传统和有机农场的效率与生产率，发现有机农场在自身技术下效率更高，但所用技术生产率低于传统农场。
This paper uses data envelopment analysis to compute overall technical and input-specific technical efficiency measures of conventional and organic farms in Finland. Moreover, productivity measures are determined, indicating differences in technology employed by organic and conventional farms. The data are from crop and livestock farms over the period 1994–1997. The results show that organic farms are on average more efficient relative to their own technology, but use a less productive technology than conventional farms.
