PRODUCTIVITY GROWTH IN AGRICULTURE (REVISITED): A MEASUREMENT FRAMEWORK AND SOME EMPIRICAL RESULTS
在投入产出分析框架下提出一种确保部门生产率增长与整体经济一致的方法，并用Tornqvist指数估计了英国农业的全要素生产率，同时考虑了农业及上游辅助产业的劳动力，发现部分农场劳动力已向上游产业转移。
This paper explores the methodology of sectoral productivity growth measurement within the framework of input‐output analysis. A method which ensures that sectoral productivity growth rates are consistent with productivity growth rates for the economy as a whole (as well as allowing for external trade) is suggested. New estimates are presented on total factor productivity in UK agriculture using a Tornqvist index procedure. In addition, new estimates of agricultural labour productivity growth are presented, taking account not only of labour employed in agriculture but also of labour employed in ancillary industries on the supply side. The empirical results confirm that part of the labour previously employed on farms has shifted “upstream” to industries providing agriculture with fertilises, machinery and other inputs.
