基于DEA-Tobit模型的河南省粮食生产效率分析
Efficiency analysis of grain production in Henan Province based on DEA-Tobit model
摘要
Abstract
Using data for 18 cities in Henan Province from 2000 to 2010 and data envelopment analysis (DEA) Henan Province grain production efficiency was analyzed; then Tobit model was used to analyzed the main influencing factors of Henan grain production efficiency. The analysis results show that Henan Province grain production efficiency level integral is higher, but these exists a redundant input in Zhengzhou, Kaifeng, Luoyang, Pingdingshan, Anyang, Puyang, Xuchang, Luohe, Sanmenxia, Nanyang and Shangqiu. Positine correlation exists between effective irrigation area and unit area grain yield and grain production efficiency, and high GDP per capita of local food production efficiency is relatively low. Therefore, in the process of food production a reasonable adjustment of factor inputs is necessary, the construction of irrigation and water conservancy facilities, should be strengthened and advanced agricultural science and technology should used to improve the efficiency of food production.关键词
