چکیده

دو عامل ابداعات داخلی و واردات فناوری از کشورهای پیشرفته نقش مهمی در افزایش تقاضای نسبی برای نیروی کار ماهر ایفا می­ کنند. این دو عامل خود متأثر از سرمایه گذاری در تحقیق و توسعه داخلی و تجارت بین­ الملل می­ باشند. در این مقاله، با به‌ کارگیری یک تابع هزینه ترانسلوگ، تأثیر فناوری و سایر عوامل تعیین کننده شامل حجم تولید و موجودی سرمایه فیزیکی بر سهم اشتغال نیروی کار ماهر برآورد شده است. داده‌ های مربوط به واردات فناوری براساس کدهای دو رقمی طبقه­ بندی بین­ المللی ISIC ، طی دوره ۱۳5۰-۱۳92 جمع­ آوری شده است. با برآورد تابع هزینه ترانسلوگ به روش رگرسیون‌ های به­ ظاهر نامرتبط، ملاحظه می­ شود که در سال‌ های مورد مطالعه،  با گسترش واردات فناوری سهم اشتغال نیروی کار ماهر در ایران افزایش و هزینه‌ های تولید کاهش یافته‌ است، همچنین نتایج تحقیق نشان می­ دهد که تحقیق و توسعه داخلی، روی اشتغال نیروی کار ماهر اثرگذار نبوده است.
