PRODUCTIVITY GROWTH AND THE UK FOOD SYSTEM 1954‐84
利用投入产出数据估算英国三个子时期各行业的生产率增长率，并分析其对食品系统满足消费者需求效率变化的贡献，强调将农业生产率研究扩展至上下游产业的重要性。
This paper uses input‐output data bases to derive estimates of industry productivity growth rates in the UK for three discrete sub‐periods. The results are then used to derive estimates of the within‐industry productivity growth contributions to the changing efficiency over time of the economic system in meeting consumers' food requirements. The resultant estimates indicate the value of extending studies of agricultural productivity growth to encompass efficiency gains in industries that are upstream and downstream of the agricultural industry.
