چکیده

یکی از ارکان توسعه و رشد اقتصادی مبتنی بر گسترش سرمایه­گذاری بخش خصوصی است. ازاین­رو، توجه به متغیرهای مرتبط در این باره و بررسی نقش آن­ها امری ضروری است. بنابراین هدف مطالعه حاضر، بررسی نقش نااطمینانی اقتصاد کلان و مخارج دولت بر سرمایه­گذاری بخش خصوصی در ایران بر اساس داده­های فصلی و سالانه در بازه زمانی 1368-1394 است. برای این منظور، ابتدا نااطمینانی اقتصاد کلان با استفاده از الگوی تلاطم تصادفی استخراج گردیده و سپس برای بررسی اثر مخارج دولت و نااطمینانی اقتصاد کلان بر سرمایه­گذاری بخش خصوصی از روش داده­های ترکیبی با تواتر متفاوت (MIDAS) استفاده شده است. نتایج نشان می­دهد که افزایش نااطمینانی اقتصاد کلان و نیز افزایش تولید ناخالص داخلی بر سرمایه­گذاری بخش خصوصی در ایران به ترتیب اثرات منفی و مثبت داشته است. همچنین مخارج مصرفی دولت تأثیر منفی بر سرمایه­گذاری بخش خصوصی دارد.

چکیده [English]

One of the foundations for development and economic growth is the expansion of private sector investment. It is necessary to pay attention to the relevant variables in this regard and to examine their role. Therefore, this study examines the role of macroeconomic uncertainty and public expenditure in determining private investment in Iran based on seasonal and annual data during 1368-1394. For this, first, the macroeconomic uncertainty was extracted using stochastic volatility model. Then, to investigate the effect of macroeconomic uncertainty and public expenditure on private investment, we usedMixed frequency Data Sampling (MIDAS) approach. The results showed that the increase of macroeconomic uncertainty as well as the increase of GDP have negative and positive effectson the private sector investment in Iran, respectively. Furthermore, the public consumption expenditure has a negative and significant effect on private sector investment and significant effect on private sector investment and significant effect on private sector investment
