To Mix or Specialise? A Coordination Productivity Indicator for English and Welsh farms
提出一种非参数协调生产率增长测度方法,分解为协调技术效率变化和协调技术变化,应用于2007-2013年英格兰和威尔士农场面板数据,发现协调无效率随畜牧业资源比例增加而显著上升,协调低效农场应增加作物种植面积。
Abstract This paper introduces a nonparametric measure of coordination productivity growth where the subprocesses are explicitly modelled in the production technology. The coordination productivity indicator is decomposed into a coordination technical inefficiency change component and a coordination technical change component. This decomposition allows assessment of reallocation impacts on the different sources of productivity growth. The empirical application focuses on a large panel of English and Welsh farms over the period 2007–2013. The results show that coordination inefficiency significantly increases with the proportion of resources allocated to livestock production in economic and statistical terms. Coordination inefficient farms should generally allocate more land to crop production. Depending on the region, the average coordination productivity growth ranges from −9.7% to 15.9% per year. It is driven by coordination technical change rather than coordination inefficiency change.
