Potential of China's grain production: evidence from the household data
基于1993-95年1000户农户调查数据，用随机变系数前沿方法测算中国粮食生产潜力，发现实际产量比潜力低15-35%，并识别出人力资本、土地规模和市场化改革是提升效率的关键因素。
This study investigates whether China has achieved its potential in grain production fully with the existing technology. A stochastic varying coefficients frontier approach is applied on recent household survey data of 1000 grain farmers covering the periods 1993-95. The results indicate that, on average, the actual grain outputs are about 15-35% lower than the potential output. The analysis has identified households' human capital stock, land size and market-oriented reform as important factors contributing positively to grain production efficiency.
