【摘要】：农业生产效率低下是制约中国农业可持续发展的关键。由信贷约束引发的资本投入不足,生产要素配比不合理,以及节水灌溉等先进技术采用率低,是西北干旱地区农业生产效率低下的主要原因。基于此,本文使用甘肃张掖367户玉米种植户调研数据,在运用随机前沿生产函数法对不同灌溉技术条件下农户生产效率进行测算的基础上,从农户信贷金额、利率和期限三个维度探析信贷约束对农户生产效率的影响,并运用分位数回归模型,检验信贷约束对不同水平生产效率的影响。研究结果发现:节水灌溉技术对农户生产效率的提高有显著促进作用;金额约束和利率约束抑制生产效率的提高,而期限约束的影响则不显著;金额约束对生产效率较低农户的影响较大,而利率约束则对生产效率较高农户的影响更为突出。
[Abstract]:The low efficiency of agricultural production is the key to restrict the sustainable development of agriculture in China. The main reasons for the inefficiency of agricultural production in arid areas of northwest China are the shortage of capital investment caused by credit constraints, the unreasonable proportion of production factors and the low adoption rate of advanced technologies such as water-saving irrigation. Based on this, this paper uses the survey data of 367 maize growers in Zhangye, Gansu Province, based on the measurement of farmers' production efficiency under different irrigation technology conditions by using the stochastic frontier production function method, and based on the amount of farmers' credit. This paper explores the influence of credit constraints on farmers' production efficiency from the three dimensions of interest rate and term, and uses the quantile regression model to test the effects of credit constraints on different levels of production efficiency. The results show that the water-saving irrigation technology has a significant effect on the improvement of farmers' production efficiency, while the amount constraint and interest rate constraint inhibit the improvement of production efficiency, but the effect of term constraint is not significant. The amount constraint has a great influence on the low production efficiency farmers, while the interest rate constraint has a more prominent effect on the higher production efficiency farmers.
