Bu çalışmanın temel amacı, 2010 - 2016 döneminde Türkiye tarım sektöründe üretimi yapılan 61 adet bitkisel ürünün Veri Zarflama Analizi (VZA) ve VZA Tabanlı Malmquist Toplam Faktör Verimlilik (MTFV) Endeksi kullanılarak etkinliklerinin ölçülmesi ve değerlendirme altındaki yıllar arasında etkinlik değişmelerinin gözlemlenmesidir. Yapılan analizlerde, her bir bitkisel ürün, karar birimi olarak değerlendirilmiştir. Etkinlik analizlerini takiben, dönemler arasındaki etkinlik değişimini değerlendirmek amacıyla Malmquist Toplam Faktör Verimliliği Endeksi analizleri yapılmıştır. Böylelikle, 2010 - 2016 yılları arasındaki Türkiye düzeyinde ürün üretim süreç etkinlik değişmeleri gözlemlenebilmiş ve değerlendirme altındaki dönemler arasında etkinlik skorlarını karşılaştırılabilme imkânı sağlanmıştır. Elde edilen sonuçlar ile Türk tarım sektörü üzerine makro boyutta bir bakış açısı sağlanması amaçlanmıştır. Etkinlik analizlerinde, 2010 - 2016 yılları arasında Türk tarımında en yüksek sayıda etkin birime sebzeler kategorisinde ulaşılmıştır. Malmquist TFV Endeksindeki en büyük ilerleme % 40,2 ile çavdar biriminde, en büyük gerileme ise % 31,8 ile pırasa biriminde gözlenmiştir. Kategorik açıdan değerlendirildiğinde, Malmquist TFV Endeksinde en büyük ilerlemeyi meyveler, içecek ve baharat bitkileri sergilemiştir.
The main objective of this study is to measure and observe the effects of 61 plant products produced in the Turkish agricultural sector in the period 2010 - 2016 using the Data Coverage Analysis (VZA) and the VZA-based Malmquist Total Factor Efficiency Index (MTFV) measuring and observing the effects of changes between the years under assessment. In the analyses performed, each plant product was assessed as a decision unit. Following the performance analysis, Malmquist Total Factor Efficiency Index analyses were conducted to assess the change in performance between periods. Thus, on the level of Turkey between 2010 and 2016, the product production process activity changes were observed and the possibility of comparing the activity scores between the periods under assessment was provided. The achieved results are aimed at providing a macro-dimensional perspective on the Turkish agricultural sector. In the analysis of the event, a large number of active units in the Turkish agriculture between 2010 and 2016 were achieved in the category of vegetables. The Malmquist TFV Index has seen a great progress in the square unit with 40.2%, and a great decline in the square unit with 31.8%. When categorically assessed, Malmquist has shown great progress in the TFV Index, fruit, beverages and spices.
The main purpose of this study is to measure efficiency and to observe efficiency change of produced 61 crops in the Turkish agricultural sector in 2010 - 2016 period with using Data Envelopment Analysis (DEA) and DEA-based Malmquist Total Factor Productivity Index. Each crop was considered as a decision-making unit in both of analysis. Following the efficiency analysis, Malmquist Total Factor Productivity Index analysis was performed to evaluate the efficiency change between the periods. Thus, efficiency change of crop production process in Turkish agricultural sector between the years 2010 - 2016 could be observed and the opportunity to compare their efficiency scores has been achieved between the periods under evaluation. The aim is to provide a macro perspective on Turkish agriculture sector with the results obtained. In efficiency analysis, the highest number of efficient units in Turkish agriculture is found in the vegetables category during 2010 - 2016. The highest increase rate of Malmquist TFV index was observed in rye unit with 40.2% and the biggest decrease rate was observed in leek unit with 31,8 %. In terms of categories, the biggest progress on the Malmquist TFP index was indicated by fruits, beverages and spice crops.
