【摘要】：节水灌溉技术采用率低下已成为制约西北干旱地区农村经济可持续发展的关键。理论研究发现,信贷约束对具有资本密集型特质的节水灌溉技术采用产生影响,而社会资本对信贷约束具有一定的缓解作用。基于此,本文使用甘肃张掖483户农户调研数据,首先,将通过意愿调查法获得的农户金额约束、利率约束和期限约束数据资料表征农户信贷约束程度,并应用探索性因子分析法构建社会资本指数;其次,运用Probit模型实证分析信贷约束、社会资本对节水灌溉技术采用的影响;再次,分别引入社会资本与金额、利率和期限约束的交互项,检验社会资本对信贷约束的缓解效应;最后,通过稳健性检验与边际效应分析对实证结果和影响程度进行检验。结果发现:(1)信贷约束的三个维度——金额约束、利率约束和期限约束分别对节水灌溉技术采用行为具有显著的抑制作用,而社会资本对农户采用节水灌溉技术具有积极促进作用。金额约束每增加1万元,节水灌溉技术采用概率降低1.96%;利率约束每上升1%,采用概率下降0.77%;期限约束每延长1年,采用概率下降2.39%;农户社会资本每提高一个档次,采用概率提升21.04%。(2)社会资本通过民间借贷等形式,对技术采用过程中的金额与利率约束有显著的缓冲功能;受民间借贷期限不稳定等因素的影响,社会资本对期限约束的缓解效应并不明显。(3)户主年龄、受教育程度、所在村庄与乡镇的距离以及是否接受过技术推广服务均对节水灌溉技术采用行为有显著影响。
[Abstract]:The low adoption rate of water-saving irrigation technology has become the key to restrict the sustainable development of rural economy in arid areas of northwest China. Theoretical research shows that credit constraints have an impact on the adoption of water-saving irrigation technology with capital-intensive characteristics. Based on this, this paper uses the survey data of 483 households in Zhangye, Gansu Province. First of all, the amount of money obtained by the will survey method will be restricted. The data of interest rate constraint and term constraint represent the degree of credit constraint, and the exploratory factor analysis is used to construct social capital index. Secondly, the Probit model is used to analyze the credit constraint empirically. The impact of social capital on the adoption of water-saving irrigation technology; third, the introduction of social capital and the amount of money, interest rate and term constraints to test the mitigation effect of social capital on credit constraints; finally, The empirical results and the degree of influence are tested by robustness test and marginal effect analysis. Interest rate constraints and term constraints have significant inhibitory effects on the adoption of water-saving irrigation techniques, while social capital has a positive effect on farmers to adopt water-saving irrigation techniques. The probability of water-saving irrigation is reduced by 1.96; the probability decreases by 0.77 for every increase of interest rate constraint; the probability decreases by 2.39 per year with the extension of the term constraint; and the social capital of farmers increases by one level. The social capital has a significant buffer function on the amount of money and interest rate constraint in the process of technology adoption, which is influenced by factors such as the instability of the term of private lending and other factors. The mitigation effect of social capital on the term constraint is not obvious.) the age of head of household, the education level, the distance between the village and the township, and whether or not the technology extension service have significant influence on the adoption of water-saving irrigation technology.
