Determining allocative-economical efficiency of joint-stock company of Shafaroud Forest based on Data Envelopment Analysis (DEA)

The aim of this study was to measure the allocative- economical efficiency of joint-stock company of Shafaroud Forest using Data Envelopment Analysis. In this study, data during period of 10 years (2002 to 2011) with two inputs (production prices, total cost) and two outputs (sales of forest products, total revenue) was collected from the company financial balance sheets. Due to the importance of this company for supplying wood products in the Guilan province, advanced models were used to estimate the cost, revenue and profit efficiency. Results indicated that this company in terms of allocative- economical efficiency was completely efficient (100% or scored 1) in (2006), (2008) and (2010) by all of these models, but the company did not have high productivity in other years. This result can be due to the nature of theses input oriented advanced models that focus on optimal inputs allocation, and could be known as a result of optimal usage and resources management.
