土地生產(chǎn)率視角下的中國(guó)土地適度規(guī)模經(jīng)營(yíng)——基于2010年全國(guó)農(nóng)村固定觀察點(diǎn)數(shù)據(jù)
[Abstract]:From the point of view of land productivity, the relationship between land productivity and land scale of wheat, paddy, corn and soybean was tested by using the data of fixed observation points in rural areas of China in 2010. The results show that wheat land productivity and land scale are inverted "U" type, and the relationship between paddy land productivity and land scale is reverse. There may be a linear positive relationship between maize and soybean land productivity and land scale. The results of comparative analysis of different regions show that the land productivity and land scale of wheat in central and western regions show an inverted "U" type, which rises first and then decreases; In the central and western regions, there is a reverse relationship between land productivity and land scale, but in Northeast China, increasing the land scale is helpful to improve the land productivity of paddy. Maize has a smaller land size and higher land productivity in the eastern region, but in the west and northeast regions, increasing the land scale is helpful to improve the land productivity. There may be no specific relationship between soybean land productivity and land scale in the eastern and central regions, but there is a positive relationship between them in the west and northeast regions.
