ÖZETMemleketimizin diğer bölgelerine nazaran Doğu Anadolu bölgesindeekonomik hayat daha fazla tanma bağlıdır ve dolayısiyle tarımsalproblemler bu bölgede dahafazladır. Bölgenin tarımsal yapısının daha iyianlaşılaNlmesi için, bölgedeki arazi mülkiyet ve tasarruf durumununtesbiti lüzumludur.Arazinin tasarruf şekli ile tarımsal üretim veya gelir arasında birilişkinin mevcut olabileceği düşünülerek bölgedeki tarım işletmeleri buyönleri ile incelenmiştir.Bu çalışmada, istatistik ve matematik tekniklerinin ekonomik olaylarauygulanması şeklinde tarif edilebilecek ekonometrik analizler yapılmış,ayrıca işletme analizlerine de yer verilmiştir. Bölgedeki tarım işletmeleri,arazi tasarruf şekillerine göre 5 grupta toplanmış ve gruplararasında, kulianılan kaynaklar ve elde edilen gelirler bakımından, farklıiıklartesbit edilerek bu farklılıkların nedenleri araştırılmıştır.AN ECONOMETRİC ANALYSİS OF FARMS ACCORDİNG TO THELAND TENVRE SYSTEMS İN ERZURUM PROVİNCEThis study is an econometric analysisof faıms, grouped on the basis ofland tenure systems, in Erzurum proYİnce.The data used in this study werecoJIected through questionnairesfılled on a ıandom sampling of 175farms which were visited during theperiod of August 15-September 15of 1969.According to the land tenure statusof the operators, the fanns includedin the sample were divided intofive groups as: GrouırA owner operatedfarms, group B- one third orless of te farm is operated under a 50pereent share cropping; groupC,between 1/3 and 2/3 of the farın is operatedunder a 50 pereent share cropping;group D- 2/3 or more of thefann is operated under a 50 pereentshare cropping; and group E- pattlyrented farıns.The yearly accomplichment levelsof farms were obtained through the applicationof some economic criteria.According to these analysis, an averageof only 34.4 pereent of ' availablefamily labor is utilized, Le. theıe is abig anı.ount of disguised unemplayınentQn farıns. Three of the four farms madenoprofit. Average per capita incometo family labor, ınanagement and OWDcapital is LI 67 Turkish lira a year. Noone of the five farm groups is operatedefficiently.The production functions of Cobb~Douglass type were derived in order toshow the funetional relationships betweenthe gross retums and the resourcesuse'! in obtaining the latter. Based onthese produetions functions, the marginalreturns of resources (at geometric meanlevels), the marginal efficieneycoefficients, and the marginal efficiencyof factor combinations were estimated.According to the intergroup analysisof variance there is not an significantdifference as to the output pro-.duced on all farms. A search was madebetween the owner operated group offarms and other groups to see whetherthe production elasticies of t,he same inputfaetors were different ard it wasfound that the produetion elasticitiesof land, livestock, seed. and' buildingof group D were different. İntergroupcomparisons proved the fact that regardlessof the land tenure status offarmers. usually the same techonolgyis applied on all farms and thus thereare not significant differences amongfaıms.
