Abstract

The aim of this study is to reveal the resource utilization pattern of county-level crop farming production in He'nan in 2010, which can provide scientific basis for formulation of crop farming production policies and adjustment of production elements. The empirical analysis of the production efficiency of 126 country-level crop farming in He'nan in 2010 is conducted by applying GIS software and DEA model from three aspects of "combined efficiency", "technical efficiency" and "scale efficiency" and non-DEA effective states of mechanical power input, pesticide input, effective irrigation area and so on are revealed. The results show that: the average value of the combined efficiency of crop farming in the research period is 0.69 and the county-level spatial differentiation is remarkable; the technical efficiency is the main factors influencing the combined efficiency and its spatial pattern is basically consistent with the spatial pattern of the combined efficiency; the average value of the scale efficiency of crop farming is 0.95, which indicates that the overall scale efficiency of crop farming in He'nan is at a higher level; it further reveals looseness of various input elements in various counties. It is suggested to optimize and adjust the element input amount and input structure by type and improve the combined efficiency of crop farming.
