【摘要】：以黑龙江省粮食主产区"两大平原"为研究区,运用双重差分(DID)模型和多元回归方法实证研究土地流转对玉米和水稻土地生产率的影响效果及原因。结果表明:1研究区农户土地流转能显著提高玉米的土地生产率,但会显著降低水稻的土地生产率。2土地流转通过改变农户经营的土地生产要素进而改变劳动和资本等生产要素的投入,从而影响土地生产率。土地流转后化肥投入的增加是玉米土地生产率提高的主要原因;土地流转后经营规模和集中连片程度增加的同时,化肥和灌溉投入减少是水稻土地生产率降低的主要原因。
[Abstract]:Taking the "two Great Plains" of Heilongjiang Province's main grain producing area as the research area, The effect of land transfer on land productivity of maize and rice was studied by using double differential DID-model and multivariate regression method. The results showed that the land transfer of farmers in the study area of 1: 1 could significantly improve the land productivity of maize. But it will significantly reduce the land productivity of rice. 2. Land circulation will change the input of factors of production, such as labor and capital, by changing the factors of land production managed by farmers. The increase of chemical fertilizer input after land circulation is the main reason for the increase of maize land productivity, while the scale of operation and the degree of concentration increase after land circulation. The decrease of fertilizer and irrigation input is the main reason for the decrease of rice land productivity.
