      <string language="tr">Bu çalışmada, parametrik olmayan yöntemlerden "Veri Zarflama Analizi, VZA" ve parametrik yöntemlerden "Stokastik Etkinlik Sınırı, SES" kullanılarak, Ranlıurfa ilinde ikinci ürün mısır tarımı yapan işletmelerin teknik, tahsis ve ekonomik etkinlik seviyeleri belirlenmiştir. Ayrıca, iki farklı metot ile saptanan etkinlik değerleri karşılaştırılarak, üretime etkisi olduğu düşünülen bazı sosyo ekonomik faktörlerin önemlilik dereceleri tobit analizi yardımı ile saptanmıştır. Çalışmada, teknik, tahsis ve ekonomik etkinlikler, VZA ile % 81, % 87 ve % 77, SES ile % 84, % 78 ve % 64 olarak bulunmuştur. İki metot ile elde edilen etkinlik değerlerinin benzerlikleri ve farklılıkları sıra korelasyonu analizi ile incelenmiş ve sonuçların örtüştüğü ortaya konulmuştur. Ayrıca hem VZA hem de SES metodu ile saptanan ölçeğe getirilerde genel bir tutarlılık gözlemlenmiştir. Uygulanan metotlar ile saptanan değerler, incelenen işletmelerde etkinsizlik olduğunu göstermiştir. Sosyo-ekonomik faktörlerden sulama sayısının ve sulama aralığının, işletmelerin etkinlikleri üzerinde istatistiksel olarak önemli bir etkisi olduğu ortaya konulmuştur.</string>
      <string language="en">In this study, technical, allocative and economic efficiency measures are derived for a sample of corn producers in Ranlyurfa using the parametric Stochastic Frontier Analysis (SFA) technique and nonparametric Data Envelopment Analysis (DEA). Efficiency measures obtained from the two frontier approaches are compared and socio economic factors affecting productive efficiencies are also analyzed using tobit regression analysis. The mean technical, allocative and economic efficiencies are 84 %, 78 % and 64 %, respectively, for the parametric approach and 81 %, 87 % and 77 % for DEA. Rank correlation analysis revealed that the efficiency rankings of the sample producers based on the two approaches are highly correlated. Also, it was found that there is a consistency in returns to scales with two methods used in this study. Thus the results from both approaches reveal considerable inefficiencies in corn production in Ranlyurfa. Analysis of the role of various socio-economic factors on productive efficiency shows that number of irrigation and watering frequency has significant effects on efficiency levels.</string>
      <string language="de">In dieser Studie, technische werden Allokations- und wirtschaftliche Effizienz-Maßnahmen für eine Probe von Mais-Hersteller in Ranlyurfa mit dem parametrischen stochastischen Frontier-Analyse (SFA) Technik und Nichtparametrische Data Envelopment Analysis (DEA) abgeleitet. Effizienzmaßnahmen gewonnenen zwei Frontier-Ansätze werden verglichen und sozio ökonomischen Faktoren, die die produktive Effizienz werden auch mit Tobit Regressionsanalyse analysiert. Der mittlere technische, Allokations- und wirtschaftliche Effizienz sind 84 %, 78 % und 64 %, für die parametrische Ansatz und 81 %, 87 % und 77 % für DEA. Rang Korrelationsanalyse ergab, dass die Effizienz-Rankings von der Sample-Produzenten, die auf der Grundlage der beiden Ansätze stark korreliert sind. Auch wurde festgestellt, daß es eine Konsistenz in liefert Waage mit zwei Methoden, die in dieser Studie verwendet. So zeigen die Ergebnisse von beiden Methoden erhebliche Ineffizienzen im Mais-Produktion Ranlyurfa. Analyse der Rolle der verschiedenen sozio-ökonomischer Faktoren auf Produktionseffizienz zeigt, dass die Anzahl der Bewässerung und Bewässerung Frequenz hat erhebliche Auswirkungen auf die Wirtschaftlichkeit.
