چکیده
بحرانهای اقتصادی اخیر (2007 تا 2008)، تمرکز بر مدیریت سرمایه در گردش را در همه شرکتهای دنیا، مورد توجه قرار داد. با توجه به اهمیت چرخههای تجاری بر وضعیت سرمایه در گردش شرکتها، در این پژوهش بهبررسی نقش چرخههای تجاری بر رابطه بین مدیریت سرمایه در گردش و سودآوری پرداخته شده است. در این پژوهش از دو معیار بازده داراییها و سود ناخالص عملیاتی برای سنجش سودآوری استفاده شده است و تعداد 200 شرکت در دوره زمانی 1391-1380 بهعنوان نمونه آماری انتخاب شدند که در مجموع تعداد 2218 سال- شرکت را ایجاد میکردند. یافتههای پژوهش حاکی از این است که تأثیر چرخههای تجاری بر رابطه بین سرمایه در گردش و سودآوری در شرایط رونق اقتصادی، برجستهتر از شرایط رکود اقتصادی است. بهعلاوه، نتایج نشان میدهد اهمیت مدیریت چرخه تبدیل وجه نقد و دوره وصول مطالبات در شرایط رونق اقتصادی افزایش مییابد؛ همچنین مدیریت کارای موجودی کالا و دوره پرداخت حسابهای پرداختنی در شرایط رونق اقتصادی کاهش مییابد. بهطورکلی، نتایج نشان میدهد مدیریت سرمایه در گردش امری ضروری و حیاتی برای شرکتها است؛ بنابراین شرکتها باید آن را در برنامههای تأمین مالی خود مدنظر قرار دهند.
