ON MEASURING YIELD POTENTIAL OF THE HIGH YIELDING VARIETIES TECHNOLOGY AT FARM LEVEL
针对发展中国家水稻农场产量远低于潜力的问题，本文从农户经济环境出发，定义了农场层面可行且符合福利目标的产量潜力测度方法。
Among rice scientists in developing countries there is a general belief that on‐farm rice yields are far below their potential level. There is considerable controversy about the appropriate methodology to define and measure the potential yield at the farm level within the farmers' environment. Most of the methodologies are based on agronomic criteria and neglect the farmers' socio‐economic environment. The aim of this paper is to define the potential yield at the farm level incorporating the economic environment farmers face. This potential yield so defined is feasible in that it could be realised by all farmers with existing technology, provided that they have access to necessary inputs. Measuring potential yield in this way is also desirable from a welfare viewpoint.
