By comparing the domestic and foreign related research, we find that in the developed countries, the advanced production technology and high government subsidies lead to a positive relationship between farmland scale and land productivity. While in the developing countries, due to the differences in the degree of factor market development, agricultural production technology and the land endowment will be a positive, negative, “U” type or the inverted “U” shaped relationship. On this basis, we explore this relationship in China and find that it will be “U” type firstly and then inverted “U” type as the scale of farmland becoming lager. Finally, in order to get a convincing conclusion, the researches should be expanded to the long term, and the more precise range of farmland scale should be carried out in the empirical analysis. %K 农地规模化 土地生产率 线性关系 “U”型关系< %K br> %K agricultural scale management land productivity linear relationship U type relationship %U http://www.xnxbs.net/xbnlkjdxskb/ch/reader/view_abstract.aspx?file_no=20170407&flag=1
