INTER‐REGIONAL FARM EFFICIENCY IN PAKISTAN'S PUNJAB: A FRONTIER PRODUCTION FUNCTION STUDY
基于1984-85年全农场调查数据，估计概率前沿生产函数，比较旁遮普省四个灌溉种植区的农业生产效率，发现缩小最佳实践与平均农户间的差距可使总收入提高13%，利润提高40%。
Agricultural production efficiency in four irrigated cropping regions of the Punjab province of Pakistan was compared on the basis of a probabilistic frontier production function estimated from whole‐farm survey data for the year 1984‐85. It is found that the gross income of farmers can be increased by 13% at the current levels of resource use if the production gap between ‘best practice’ and ‘average’ farmers is suitably narrowed in all cropping regions. This will increase profits by up to 40%. No significant difference in technical efficiency was found across the regions. Economic efficiency was similar across all cropping regions except in the cotton region, which had significantly lower economic efficiency due to higher allocative inefficiency, which in turn was attributable to the more dynamic production technologies being adopted in that region.
