摘要
研究目的:对中国"七五"到"十五"期间区域农地的生产效率差异进行比较研究。研究方法:数据包络分析DEA的C2R模型和BC2模型。研究结果:(1)传统农业大省和经济发达地区的农地综合生产效率和技术效率较高,农业生产具有优势。(2)规模收益值的计算结果显示,东中部地区农业生产的投入结构存在着问题,西部地区投入不足。(3)从时间序列的比较分析中发现,在"十五"期间各地区的农地生产效率都出现了下降趋势,表明工业化和城市化对中国农业生产存在较大影响。
The purpose of this study is to analyze the productive efficiency difference of regional farmland in China from the 7th Five-Year Plan to the 10th Five-Year Plan. Methods of C2R model and BC2 model of Data Envelopment Analysis （DEA）were employed. The results indicate that,（ 1 ）the traditional agricultural provinces and developed areas enjoy comparatively higher farmland productive efficiency and technology efficiency with greater advantage in agricultural production;（2）the result of scale returns shows that there is still room for improvement in agricultural input mechanism in the eastern and middle areas while the western areas are short of input;（3）in the comparative analysis of time series, it is found that during the 10th Five-Year Plan period, farmland efficiency tended to decline in some areas, which suggests that industrialization and urbanization have a considerable influence on agricultural production.
