摘要
本文用DEA方法估算了我国28个省份1980-2005年的农业生产率,分析表明:①我国农业生产率在1980~2005年间平均年增长速度为2.2%,其中技术进步率为4.2%,而相对技术效率则以1.9%的速度恶化;②1980~1989年间,农业生产率的变化较好地解释了农业生产的波动,而1990年以后,农业生产波动更多地受到生产率以外因素的影响;③从地域上看,东部地区的生产率增长率与技术进步率要快于中、西部地区。在技术效率上,中、西部地区均有不同程度的恶化;④我国农业生产率增长的主要源泉是技术进步。收敛性检验表明,我国农业生产率在总体上存在收敛趋势。
Using DEA approach, we have estimated the agricultural produc- tion efficiencies of 28 provinces during 1980 to 2005. Our analysis indicates: ①The growth of China's agricultural productivity effieieneies is about 2. 2%, and the technological progress about 4.2%, but the technology efficiency is worsen with the speed of 1.9% every year during 1980 to 2005; ②During 1980 to 1989, the change of efficiency had made a good explanation of the growth of agriculture produces ; ③The TFP growth and the technological progress is faster in eastern regions than in middle and western regions, and the technology efficiency is worsen in middle and western regions; OIt is the technological progress who boost the TFP growth in China's agriculture. And there exists σ-convergence in the agricultural production efficiency of our country as a whole.
