چکیده مقاله :

توانایی مدیریت بر فعالیت هایی همچون تحقیق و توسعه، بهای تمام شده، هزینه های مالی، دارایی ها و درآمد شرکت ها تاثیر می گذارد و کارایی آنها نیز به این عوامل بستگی دارد. هدف این تحقیق، ارزیابی کارایی نسبی در صنعت سیمان عضو بورس ایران به عنوان شاخصی برای سنجش توانایی مدیریت با یک الگوی جدید بسط داده شده است. برای این کار از داده های صورت های مالی شرکت های سیمان در طی سال های90 الی94 استفاده شده است. ابتدا با اجرای مدل تحلیل پوششی داده ها، کارایی نسبی هر یک از شرکت ها ارزیابی شده و واحدهای کارا نیز با روش اندرسون- پیترسون رتبه بندی شده اند. سپس با برآورد یک مدل رگرسیونی، شاخص توانایی مدیریت هر کدام از شرکت ها با یک الگوی مناسب، محاسبه شده است. برای سنجش و ارزیابی کارایی نسبی از نرم افزار بهینه سازی GAMS و جهت سنجش شاخص توانایی مدیریت از نرم افزار E-Views بهره گرفته شده است. منظور ما در این تحقیق رسیدن به توانایی غیرذاتی مدیران در واحدها بوده است. یافته های تحقیق نشان داده که کارایی یا عدم کارایی شرکت ها می تواند به توانایی ذاتی و اکتسابی مدیران مرتبط باشد. بر این اساس نتایج بیانگر آنست که شرکت هایی که با امتیاز کارا ارزیابی شده اند (مثل؛ ایران گچ و سیمان اردبیل)، صرفا تضمینی برای بالا بودن توانایی مدیران آنها نبوده است. از طرف دیگر، برخی از شرکت هایی که کارا ارزیابی شده اند (مثل؛ سیمان خوزستان و سیمان مازندران)، توانایی مدیران آنها نیز بالا بوده است.

چکیده انگلیسی:

The management ability affects activities such as R & D, cost, financial costs, assets and firm's income. Their efficiency also depends on these factors. The purpose of this study is to measure the ability of management in the cement industry with a new pattern has been member of the Iranian stock exchange. To do this, data from financial statements of companies at 2012 to 2016 years were used. First, by implementing a suitable model and regional Data Envelopment Analysis model, Relative efficiency for each of the companies is calculated and efficient units also have been ranking with Anderson-Peterson method. Then estimate a regression model, the index is calculated to management ability each of the firms. For evaluating the relative efficiency optimization software GAMS and to determine the ability of management software E-Views is used. We aim to achieve non-inherent ability of managers in units. The results of the research show that the efficiency or Inefficiency of the companies can be related to the inherent and acquired ability of managers. The results indicate that companies that have been evaluated with a score efficiently (For example; Iran Chalk Co. & Ardabil Cement Co.), not simply guarantee for high ability of their managers. While, some companies have been efficiently evaluated the ability of their managers is also high. For example; Khuzestan Cement Co. & Mazandaran Cement Co.
