摘要
The present study applies a bootstrapped DEA procedure to compute bias corrected measures of technical and scale efficiency of Chinese litchi farmers. DEA approach is appropriate to estimate the efficiency but the result is ambiguous due to lack of information about estimates' uncertainty. The present study overcomes this drawback by applying bootstrapping procedure to DEA. The data is collected from 160 farm household spread across the six southern provinces of China during 2014. The result revealed that the mean technical efficiency is 0.804 in study area which suggest that farm households are potential for producing 80% of litchi. The scale efficiency score imply that a majority of litchi farmers are operating with decreasing returns to scale. We also examine farmer's characteristics with respect to input use under various returns to scale. The bootstrap procedure corrected bias in technical efficiency scores from a mean of 0.804 to 0.66. So it is important to use bootstrap technique to reduce the ambiguity of result.
