Harran Ovasında Pamuk Üretim Teknolojisinin Analizi
Bu çalışmada işgücü, sermaye ve arazi (işletme büyüklüğü) faktörlerinin, Harran Ovasında faaliyet gösteren pamuk çiftçilerinden çekilen bir örnek üretici kitlesine ait brüt üretim miktarına nasıl tesir ettikleri ve bu ilişkinin, fonksiyon katsayısı olarak da bilinen ölçeğe-getiri parametresinin tahmin edilmesinde nasıl kullanılacağı araştırılmıştır. Regresyon analizinden elde edilen sonuçlara göre, sözü edilen bu faktörlerden işletme büyüklüğünün, pamuk üretiminde en etkili faktör olduğu ve bunu sırasıyla, sermaye ve işgücü faktörlerinin izlediği saptanmıştır. Bununlabirlikte, örnek işletmeler için hesaplanan ölçeğe getiri parametresi 1’den büyük olup, lineer ilişki varsayımı altında, bölgedeki pamuk üretim teknolojisi ölçeğe artan getiri özelliği taşımaktadır.
An Analysis of Cotton Production Technology on the Harran Plain
In this research, it was aimed to determine effects of three production factors; labor, capital, and land, on the current level of cotton output produced by a sample of local cotton farmers operating on the Harran Plain in Turkey and whether this relation may be used to assess the returns-to-scale parameter, also known as the function coefficient in the production economics literature. Regression results led us to conclude that among these variables, farm size is found the most influential variable determining cotton output, followed by the variables representing capital and labor as the second and third influential, respectively. In addition, results demonstrated that the returns-to-scale parameter calculated for this sample is significantly greater than unity suggesting that cotton production technology in this region exhibits increasing returns to scale, assuming linear technology.
