تقدير الإنتاجية الكلية لعوامل الإنتاج للقطاع الزراعي في دول نامية مختارة

الملخص EN

With limits to further expansion of cultivated land and diminishing returns to further input intensification, there is growing need for food supply increases that could only, perhaps, originate from total factor productivity growth (TFPG), rather than increase in inputs.

Based on this fact, current study aimed to determine the contribution of (TFPG) in agricultural growth for six developing countries, namley: Iran, Iraq, Jordan.

Lebanon, Seryia and Turkey, during the period (1981-2007), using Solow’s methodology to derive (TFPG).

Generally, results showed at the aggregate level the value of (TFPG) amounted to (2.12 %), indicating that it’s contribution in agricultural growth, (which amounted to 2.7 %), was (78.56 %), while the rest of the growth is attributed to contribution of the five tradional inputs.

Finally, we conclude that TFP of agricultural sector should be increases in order to accelerate the pace of agricultural growth.
