This paper investigates the impact of government size on economic growth in selected economies of the MENA countries by using a non-linear panel data approach over the period 1990-2011. The estimation results of Panel Smooth Threshold Regression model show that when the level of government consumption is very large, the positive impact of labor force on growth is intensified. On the other hand, export revenues in the countries under investigation have no positive effect on economic growth when the level of government consumption is high. The main result of this study confirms the negative impact of consumption expenditures on economic growth in this block of countries.

Abstract [Persian]

مقاله حاضر اثر اندازه دولت بر رشد اقتصادی را در کشورهای منتخب منطقه منا با به­کار گیری رهیافت داده ­های تابلویی غیرخطی در طول دوره زمانی 1990-2011 بررسی می­کند. نتایج حاصل از تخمین مدل رگرسیونی انتقال ملایم تابلویی نشان می­دهد که شدت اثر مثبت نیروی کار بر رشد اقتصادی در سطوح بسیار بالای اندازه دولت افزایش یافته است و برخلاف اثر مثبت سرمایه­ گذاری بر رشد اقتصادی در سطوح پایین اندازه دولت، اثر آن منفی تخمین زده شده است. از سوی دیگر، در سطوح بالای اندازه دولت، درآمدهای صادراتی در کشورهای تحت بررسی اثر مثبتی روی رشد اقتصادی ندارند. اصلی­ ترین نتیجه مطالعه حاضر بیان می­کند که اثرات تخریبی مخارج مصرفی دولت با تأکید بر اثر منفی این مخارج بر رشد اقتصادی تأیید می­ گردد.
