摘要
利用超越对数随机前沿生产函数模型,深入分析黑龙江省种粮大户粮食生产技术效率以及技术效率影响因素。研究结果表明,全样本种粮大户生产技术效率均值为62.23%,进步空间很大,100～130亩规模组大户生产技术效率值最高为71.92%,并具有经营规模与技术效率之间较强的"反向"作用效应。种粮大户资源禀赋中各变量对技术效率影响效应具有明显差异性,户主年龄、文化程度、身体状况、经营规模、家庭农业投入人口、技术变量、社会环境1、社会环境2都对技术效率有正向影响效应,种粮总收入、信贷可获得性、社会环境3、信息服务变量有负效应。
Using Tanslog Stochastic Frontier Production Function Model, this paper analyzes the technical efficiency of grain pro- duction and its influencing factors in large-scale grain production households in Heilongjiang Province. The results show that average ef- ficiency value of production technology is 62.23% in all samples and has much room for improvement, and it is up to 71.92% in 100- 130mu group, where management size and farmer households＇ technical efficiency display an ＂reverse＂ tendency. The resource endow- ments of household age, education, health, management size, family agricuhural population, technical variables, social environment 1 and social environment 2 have a marked positive effect on the production efficiency of large-scale grain production households, and those of grain income, credit availability, social environment 3 and information service have a negative effect.
