| 摘 要： | 利用DEA方法和Malmquist生产率指数模型方法对吉林省2001~2009年农地要素资源的投入生产效率及其变化特征进行了深入的研究,结果如下:①农地生产效率研究显示,2001~2009年吉林省农地生产综合技术效率相对较高,在未达到DEA有效的年份,规模效率对综合效率有着较大的影响;从区域特征上看,2001~2009年中部地区平均综合效率水平高于东西部地区,东西部地区平均综合效率水平相当;②农地生产效率变化研究显示,吉林省各地区2001~2009年相邻年份农地利用的综合效率变动相对较小,历年全要素生产率则在总体上保持了一定的增长趋势;2001~2009、2001~2005和2005~2009三组对比时间点的农地生产效率变化显示东中部地区的农地生产平均综合效率呈现下降趋势,西部地区综合效率呈增长趋势,东中西部地区的农业要素生产率均呈增长趋势,西部地区变化最为明显。

| Abstract: | The rapid urbanization and industrialization activities have limited the amount of land available for extensive agricultural purposes.Hence,it is of prime importance to evaluate the efficiency of land utilization so as to guarantee food security and industrial production of raw materials.An analysis of the efficiency of land utilization in Jilin Province from 2001 to 2009 was carried.Several agricultural inputs such as labour,total power of agricultural machinery,effective irrigated area,consumption of chemical fertilizer and total sown area were examined.The Data Envelopment Analysis(DEA) method and Malmquist index model were used to evaluate the production efficiencies and the various features in the land.The results showed that efficiency change(EC) is relatively high,while the scale efficiency had a great impact on the EC in the years that the DEA was ineffective.The central region was found to have a higher comparative mean EC.However,the mean EC of the Western and Eastern regions were equivalent.The variation of agricultural production efficiency showed that the annual total factor productivity change(TFPC) and the EC in 2001-2009,2001-2005 and 2005-2009 were in a gradual trend;some like the Eastern and Central Jilin Province were increasing slightly while the Western Jilin Province had an evident upward increase. |
