Due to the importance of this company, dual input- oriented data envelopment analysis models was used to measure its efficiency. <br /><strong>Results:</strong><strong> </strong>The results indicated that this company in some production units (such as: newspaper, white kraft liner and fluting line 1) had a good efficiency score (%100 efficient or score 1). But, according to the input-oriented sample of these models and scale efficiency model (SE), the rest of production units were inefficient. <br /><strong>Conclusion:</strong> Hence, this company must reduce its consumption of finical inputs (similar to efficient units) until it increases its scale efficiency of production units and profitability. <br />.  <strong></strong> <br />   <strong>Background and objectives: </strong>In this study, due to increasing of cardboard and paper products demand and consumption in Iran and also the important role of Mazandaran Wood and Paper Industries Company as a great supplier of paper products, the relative performance of the production units of this company was measured. <br /><strong>Materials and methods: </strong>In order to do this research, required data for a period of 6 years  (2005 up to 2010) and 6 production units was collected form the company financial balance sheets.
