摘要:
研究了金融支持设施农业发展的模式、机制及路径。依据江西省宁都县2004—2022年统计年鉴数据,采取OLS回归探究了宁都县年末贷款余额对农业产值的影响,以财政收入作为中介变量考察了年末贷款余额对农业产值是否存在影响,分别采用了逐步系数回归法、Sobel检验法和Bootstrap检验法。结果表明,年末贷款余额的增加对农业产值存在正向的作用,年末贷款余额每增加一个单位,会使得农业产值增加11.47%,财政收入作为中介效应也存在正向效应。
Abstract:Model, mechanism, and path of financial support for development of facility agriculture were studied.Based on statistical yearbook data of Ningdu County, Jiangxi Province from 2004 to 2022, OLS regression was first used to explore impact of year-end loan balance on agricultural output value in Ningdu County.Fiscal revenue was used as an intermediary variable to examine whether year-end loan balance has an impact on agricultural output value, using stepwise coefficient regression, Sobel test, and Bootstrap test, respectively.Results indicated that increase in year-end loan balance has a positive effect on agricultural output value.For every unit increase in year-end loan balance, agricultural output value increases by 11.47%, and fiscal revenue also has a positive mediating effect.
