劳动同酬、最大利润与中国粮食生产的适度规模

Equal Pay, Maximum Profit and Moderate Scale of China's Grain Production

适度规模是构成粮食生产效率的关键指标,现代农业发达国家的粮食生产数据显示出种植规模与生产效率的正相关。当然,不同区域的粮食生产的适度规模受制于资源禀赋与技术条件。为推导出当前中国粮食生产的适度规模,利用2011—2015年中国26个产粮省域的面板数据,构建C-D生产函数与成本、利润联立方程,以劳动同酬为条件函数,以农户利润最大化为目标函数,运用固定效应模型测算出在现有约束下中国粮食生产适度规模为劳均12.81—17.91公顷,户均35.88—50.16公顷。因此,提出创新土地流转方式、扩大融资渠道、培育新型职业农民、制定与规模挂钩的扶持政策等方式扩大中国粮食生产规模的建议。

Moderate scale is the key index that constitutes the efficiency of grain production.The food production data of modern agricultural developed countries show that the scale of planting is positively correlated with the efficiency of production.Of course,the moderate scale of food production in different regions is subject to resource endowments and technical conditions.To derive the moderate scale of China’s grain production,using the 2011-2015 panel data of 26 provinces and cities grain production in China,building the C-D production function and cost,profit simultaneous equations,labor conditions of equal pay for function,with farmers profit maximization as the objective function,using fixed effect model to measure China’s grain production moderate scale under the existing constraints of law are 12.81-17.91 ha/workforce,35.88-50.16 ha/door.Therefore,proposing to expand the scale of grain production in China by innovating land transfer mode,enlarging financing channels,cultivating new professional farmers,and formulating supporting policies that are linked to size.
