- Abstract
Using data envelopment analysis (DEA) method, Selecting effective irrigation area, crop planting area, fertilizer inputs, pesticides, rural employed population as input indexes, agricultural output, food production as output indexes, taking Guizhou province as the research object, to measure and analyze the input-output efficiency of agriculture in 2003-2012. The results showed that:(1) The volatility change of comprehensive efficiency of agricultural input and output was smaller nearly 17 years in Guizhou province, generally in a nearly optimal state. Scale efficiency was the main factors influencing the overall efficiency of agricultural input and output in Guizhou. (2) In the case of Variable Return Scale, invalid year of efficiency appeared input redundancy, In the redundant indicators, crop planting area, fertilizer input and pesticide use were bigger; There were excessive reclamation, excessive use of fertilizers and pesticides, by cutting the input redundancy can make agricultural production efficiency to achieve the optimal state. The results of the analysis can provide some useful reference for t ecological environment construction and the sustainable development of ecological agriculture in Guizhou province.
