ملخص المقالة :
تاثیر فناوری اطلاعات و ارتباطات بر افزایش تراکنش‌های مالی در زمینه‌های مختلف نشان از تحولات مثبت این صنعت در ایران دارد. اما آیا صنعت فاوا توانسته است در اقتصاد سرمایه‌ای کشور نیز کارا باشد؟ صنعتی که با ماهیت کمک به انتقال و تحلیل اطلاعات پدیدار شد، خود کارایی اطلاعاتی دارد؟ در این پژوهش، صنعت فاوا در بورس تهران مورد بررسی قرار گرفت تا کارایی اطلاعاتی آن سنجیده شود. بدین منظور داده‌ها و اسناد مرتبط با شرکت‌های فعال در این صنعت طی بازه‌ای 6 ساله بصورت کمی مورد بررسی قرار گرفت. در مجموع 8 شرکت با ماهیت فاوا انتخاب گردید. برای پی بردن به کارایی اطلاعاتی از آزمون گردش‌ها با دو رویکرد گردش با تغییر علامت و گردش با تغییر نسبت به میانگین استفاده شد. نتایج نشان داد که صنعت فاوا در بورس تهران، حتی کارایی اطلاعاتی در سطح ضعیف ندارد. نتیجه‌ای که کاملا مغایر با سایر کشورهای جهان است و نشان می‌دهد که وضع فناوری اطلاعات و ارتباطات کشور نیاز به تامل اساسی دارد.
