چکیده

هدف مطالعه حاضر بررسی تاثیر نوآوری بر صادرات کشورهای منتخب درحال توسعه و توسعه یافته طی دوره زمانی 2012-2007 با رهیافت پانل دیتا و با روش تخمین معادلات رگرسیون به ظاهر نامرتبط (SUR) در قالب سیستم معادلات همزمان است. براساس یافته های برآورد معادله عمومی در کشورهای درحال توسعه، ضرایب متغیرهای شاخص جهانی نوآوری و تولید ناخالص داخلی، مثبت و معنادار و ضرایب شاخص حکمرانی و انباشت جریان ورودی سرمایه گذاری مستقیم خارجی، مثبت و بی معنی است، درحالی که در کشورهای توسعه یافته، ضرایب متغیرهای انباشت جریان ورودی سرمایه گذاری مستقیم خارجی، شاخص جهانی نوآوری، تولید ناخالص داخلی و شاخص حکمرانی، مثبت و معنادار است. شایان ذکر است، بخش قابل توجهی از اثرات نوآوری بر صادرات در کشورهای توسعه یافته با سازوکار غیرمستقیم (از کانال تولید ناخالص داخلی، سرمایه گذاری مستقیم خارجی و شاخص حکمرانی) بر صادرات اعمال می گردد. اما در کشورهای درحال توسعه، وضعیت معکوس کشورهای توسعه یافته ملاحظه می گردد.

چکیده [English]

Exports as the engine of the economy plays a role in global markets, because export take advantage of global markets to provide manufacturing firms and lift market restrictions on domestic manufacturing firms and the use of economies of scale. So the aim of this study is to evaluate the effect of innovation on exports of selected developing and developed countries over the period 2007-2012 using panel data approach and by estimating Seemingly Unrelated Regression (SUR) for a system of simultaneous equations. According to the general export equation estimations indicate that in developing countries, Global Innovation Index and GDP coefficients are positive and significant and the coefficients of governance and accumulation of FDI inflows is positive and meaningless and in developed countries, coefficients of accumulation of FDI inflows , Global Innovation Index, GDP and governance is significantly positive. However, the indirect effects of innovation on exports indicate that indirect effects such as direct effects of both developing countries and developed countries are positive. It is noteworthy that a significant portion of GII effects on export in developed countries is applied by indirect mechanism (the channels of GDP, FDI and governance index) but in developing countries, the reverse situation is observed .
