Abstract: Although draft animals have been playing an essential role in agricultural production worldwide, in recent decades there has been a trend towards replacing draft animals with farm machines. In the areas facing labour shortage due to rural-to-urban migration, the use of farm machines is especially expected to enhance agricultural production and productivity. However, little is known about the extent to which the farm machine use substitutes draft animal use and how the two production activities jointly affect agricultural performance. To fill this gap, this paper attempts to examine the long-run and short-run effects of farm machine use on draft animal use using a pooled mean group estimator, and to estimate the joint effects of farm machine use and draft animal use on agricultural productivity using a panel production function model. The empirical results show that a 1% increase in farm machine use rate tends to decrease draft animal use by 2.82% in the long-run, but it does not have a statistically significant impact on draft animal use in the short-run. In addition, we find that output elasticity of farm machine use has increased from ?0.161 in 1978 to 0.170 in 2012, while that of draft animal use has decreased from 0.185 to ?0.129 over the same time period. Our findings highlight the importance of government’s efforts in promoting an agricultural transition from animal power to machine power in order to increase sustainable agricultural production.
