基于DEA-Tobit两步法的主产区玉米生产技术效率分析
Technical Efficiency of Corn Production in Main Producing Region in China Based on DEA-Tobit
摘要
Abstract
The Panel Data of com production in 11 provinces are analzed, such as Jilin, Heilongjiang, Liaoning, Inner Mongolia, Hebei,Shandong, Henan, Anhui, Jiangsu, Hubei and Sichuan. Based on the CRS, VRS and Malmquist exponential models of DEA, technical efficiency of corn production is measured in main producing region by DEA-Tobit. And its influencing factors are analyzed. Result shows that corn production in main producing areas is mainly scale inefficiency and is at the stage of decreasing returns to scale. Pure technical efficiency of corn production is effective in most main producing regions. Total Factor Productivity of corn production is improved in main producing regioas, because the speed of technical progress is greater than the speed of efficiency reduction. In the years 1998 -2008, corn production in main producing regions is rational in structure and is not affected by the natural disasters.关键词
