摘　　要：利用超效率DEA模型和多元线性回归模型分析黄淮海地区1999-2005年粮食生产效率变化及影响因素。通过分析研究结果表明:2000-2003年黄淮海地区粮食生产的相对效率无效,至2003年粮食产量降到近年来的最低点,2004年和2005年粮食生产相对效率提高到有效范围,但是至2005年底黄淮海粮食生产的超效率值仍未达到1999年的粮食生产效率的状态。在影响黄淮海地区粮食生产效率的影响因素分析中,灌溉保证率和人均粮食产量的增加有利于黄淮海地区粮食生产效率的提高;单位农作物播种面积第一产业增加值、乡村人口占总人口比例、粮食占农作物播种面积比例的提高、单位农作物播种面积农业劳动数量的减少有利于其粮食生产效率的提高。图1,表3,参21。This article uses super-efficiency of Data Envelopment Analysis （DEA） and multiple linear-regression to analyse the varia- tions of relative efficiency of food production of Huang-huai-hai region and its influencing factors from 1999 to 2005. The results show that the relative efficiencies of Huang-huai-hai region from 2000 to 2003 are void and fells to the lowest point in 2003 while its relative efficiencies rise to the effective range in 2004 and 2005. However, the super-efficiency value of grain production of Huang-huai-hai re- gion in 2005 is still lower than in 1999. Among factors affecting relative efficiency of grain production of Huang-huai-hai region, in- creasing the guaranteed irrigation rate and grain output per member are favorable for heightening the relative efficiency of food produc- tion of Huang-Huai-Hai region, while reducing the industrial added value per unit crop sown area, the proportion of rural population to total population, the ratio of the grain crop and sow,, area of farm crops, the number of agricultural labor on unit area are favorable for heightening its relative efficiency of food production.
