- W2370085296 abstract "This article measured agricultural efficiency of the Huang-Huai-Hai Plain in 2000-2010 by using the method of data envelopment analysis(DEA).Then it classified the agricultural efficiency into pure technological efficiency and scale efficiency for exploring the spatial and temporal characteristics of the agricultural efficiency and its evolution factors. The results suggest that: 1) The overall efficiency on the whole is on medium and low level and there exists large regional differences with high efficiency county located in the suburban.This may be attributed to development of urban and suburban agriculture in these areas. 2) The overall study period fluctuated significantly and there is no growth trend; coefficient of variation is larger in some of the county along the Huanghe River, reaching above 0.060. 3) Overall efficiency is influenced by the combined effect of pure technical efficiency and scale efficiency. Scale efficiency of most counties are efficient, with scale efficiency greater than pure technical efficiency. Pure technical efficiency of the overall efficiency is slightly stronger than the scale efficiency. 4) The counties with higher pure technical efficiency gradually shift from east to west, and in suburban the pure technical efficiency is relatively high. The counties of lower pure technical efficiency gradually transfer from north to south. The counties of general pure technical efficiency are gradually transferred to the upstream region of the Haihe Plain. 5) Scale efficiency is higher, and distributed in a balanced way. 6) Most of the efficiency of agricultural production is in the developmental stage of increased scale returns in the Huang-Huai-Hai Plain." @default.
