Comparative analysis on the technical efficiency of rice production in three counties along the Huai river in Anhui Province
Based on the survey data of rice growers in the Huai River region of Anhui Province,the DEA model was used to measure the technical efficiency of rice production,and the differences in rice production technology ef-ficiency among different regions and scale growers along the Huai River were compared and analyzed.Research has found that the comprehensive technical efficiency of rice production in Shou County was 0.934,which was higher than 0.872 in Yingshang County and 0.865 in Funan County.In terms of pure technical efficiency,Funan County was 0.972,which was higher than Shou County's 0.963 and Yingshang County's 0.924;in terms of scale efficiency,Shou County was 0.968,which was higher than Yingshang County's 0.942 and Funan County's 0.887.The techni-cal efficiency of rice production showed an overall inverted U-shaped trend with the change of scale,the highest comprehensive technical efficiency was achieved by farmers on a scale of 6.67～13.33 hm2,and land management scales that were too large or too small was not conducive to improving production efficiency.
