英文文献摘要:
Limited data on the allocation of inputs to different activities has limited agricultural economists' attempts to measure sub-sector productivity growth in agriculture. However, recent developments have enabled us to estimate total factor productivity (TFP) growth for crops and livestock accounting for input-output allocation. This paper extends previous work on TFP measurement for livestock into ruminants and non-ruminant productivity measurement, given the differences in productivity growth rates among these species. The results show that the non-ruminant sector is more dynamic than the ruminant sector, driving most of the productivity growth within the livestock sector. Given the rapid rates of productivity growth observed recently, non-ruminant productivity in developing countries may soon be converging to the productivity levels of developed countries.
对不同活动投入分配的数据有限,限制了农业经济学家衡量农业分部门生产率增长的努力。然而,最近的发展使我们能够估计作物和牲畜的全要素生产率(TFP)增长,计入投入产出分配。鉴于家畜生产力增长率的差异,本文将以往对家畜TFP测量的研究扩展到反刍动物和非反刍动物的生产力测量。结果表明,非反刍动物部门比反刍动物部门更具活力,推动了畜牧部门生产率的大部分增长。鉴于最近观察到的生产率快速增长,发展中国家的非反刍动物生产率可能很快会趋同于发达国家的生产率水平。
