【摘要】：節(jié)水灌溉技術采用率低下已成為制約西北干旱地區(qū)農村經(jīng)濟可持續(xù)發(fā)展的關鍵。理論研究發(fā)現(xiàn),信貸約束對具有資本密集型特質的節(jié)水灌溉技術采用產生影響,而社會資本對信貸約束具有一定的緩解作用�；诖�,本文使用甘肅張掖483戶農戶調研數(shù)據(jù),首先,將通過意愿調查法獲得的農戶金額約束、利率約束和期限約束數(shù)據(jù)資料表征農戶信貸約束程度,并應用探索性因子分析法構建社會資本指數(shù);其次,運用Probit模型實證分析信貸約束、社會資本對節(jié)水灌溉技術采用的影響;再次,分別引入社會資本與金額、利率和期限約束的交互項,檢驗社會資本對信貸約束的緩解效應;最后,通過穩(wěn)健性檢驗與邊際效應分析對實證結果和影響程度進行檢驗。結果發(fā)現(xiàn):(1)信貸約束的三個維度——金額約束、利率約束和期限約束分別對節(jié)水灌溉技術采用行為具有顯著的抑制作用,而社會資本對農戶采用節(jié)水灌溉技術具有積極促進作用。金額約束每增加1萬元,節(jié)水灌溉技術采用概率降低1.96%;利率約束每上升1%,采用概率下降0.77%;期限約束每延長1年,采用概率下降2.39%;農戶社會資本每提高一個檔次,采用概率提升21.04%。(2)社會資本通過民間借貸等形式,對技術采用過程中的金額與利率約束有顯著的緩沖功能;受民間借貸期限不穩(wěn)定等因素的影響,社會資本對期限約束的緩解效應并不明顯。(3)戶主年齡、受教育程度、所在村莊與鄉(xiāng)鎮(zhèn)的距離以及是否接受過技術推廣服務均對節(jié)水灌溉技術采用行為有顯著影響。
[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.
