To improve the welfare of the rural poor and keep them in the countryside,
the government has been
spending 40% of the value of agricultural GDP on agricultural support services. But
can investment make
smallholder agriculture prosperous in such adverse conditions? This paper derives
an answer by applying a
two-output six-input stochastic translog distance function, with inefficiency
effects and biased technical
change to panel data for the 18 districts and the commercial sector,
from 1979 to 1996. This model
demonstrates that herds are the most important input, followed by draft power, land
and seeds. Multilateral
indices for technical change, technical efficiency and total factor productivity
(TFP) show that the
technology level of the commercial sector is more than six times that of traditional
agriculture and that the
gap has been increasing, due to technological regression in traditional agriculture
and modest progress in the
commercial sector. Since the levels of efficiency are similar, the same pattern is
repeated by the TFP indices.
This result highlights the policy dilemma of the trade-off between efficiency and
equity objectives.
