- W2145020072 abstract "By linking DEA model to GIS technologies, this paper makes an empirical analysis about food production efficiency of 138 counties in Hebei Province from three aspects: total factor efficiency, technical efficiency and technological progress efficiency. The result shows that :1) The food production efficiency in Hebei Province grows rapidly during this period, and the production efficiency of different kinds of food shows a higher relation, and the technical efficiency has a large influence on the total factor efficiency, with a correlation coefficient 0.50, (2) Spatial distribution of food production efficiency within the province area is evident, and total factor efficiency in latitudinal direction presents an inverse U type distribution trend, meanwhile technical efficiency shows the first order distribution trends. (3) In the 138 counties, the food production efficiency significantly differs, among which predominance areas of total factor efficiency mainly include Shijiazhuang, Hengshui and other mid-eastern regions, while the non-dominant northern zone are mainly located in the north. Compared with traditional methods, the method of linking DEA model to GIS technologies has certain advantages in estimates and spatial analysis of food production efficiency." @default.
