农机购置补贴政策在“工业反哺农业”、加快农业现代化进程中发挥着不可替代的“杠杆”作用。文章在梳理农机购置补贴及财政支农支出的传导机制和拓展柯布-道格拉斯生产函数的基础上,基于省际面板数据,分别对我国粮食主产区和非粮食主产区的农机购置补贴与财政支农支出传导机制的有效性进行实证研究,结果表明:(1)粮食主产区和非主产区的农机购置补贴及财政支农支出的传导机制均是有效的;(2)粮食主产区和非主产区的土地生产率对单位面积土地上农机购置补贴的弹性分别为0.0045、0.0189;(3)粮食主产区和非主产区土地生产率对单位面积土地上财政支农支出的弹性依次为0.33、0.25。
The purchase subsidy policy of agricultural machinery plays an irreplaceable “lever ” role in “industrial nurturing agriculture ” and accelerating the process of agricultural modernization. Based on the inter-provincial panel data, the paper analyzes the mechanism of purchasing subsidies for agricultural machinery and the transmission mechanism of financial support for agriculture, and expands the Cobb-Douglas production function. Based on the panel data of provinces, The results show that: (1) The subsidies for agricultural machinery purchase in the main and non-main grain-producing areas and the transmission mechanism of financial support for agriculture are both effective; (2) (3) The productivity of land in non-main producing areas and non-main producing areas is respectively 0.0045, 0.0189 for agricultural subsidies on unit area of land; (3) Flexibility followed by 0.33,0.25.
