Türkiye Ekonomisinde Ar-Ge Yatırım Harcamaları, Patent, Endüstriyel Tasarım, İhracat ve Reel Ekonomik Büyüme Arasındaki İlişkinin İncelenmesi

Bu çalışmada; Türkiye ekonomisi için 2000-2019 döneminde ar-ge yatırım harcamaları, patent sayısı ve endüstriyel tasarım, ihracat ve reel ekonomik büyüme arasındaki ilişkiler analiz edilmektedir. Serilere ilk olarak Zivot-Andrews yapısal kırılma testi uygulanmıştır. İkinci olarak seriler arasında eşbütünleşme EngleGranger eşbütünleşme testi ile incelenmiştir. Üçüncü olarak seriler arasındaki nedensellik ilişkileri test edilmiş ve bunun için Engle Granger ve Hatemi-J asimetrik nedensellik testleri kullanılmıştır. Bu çalışmada iki farklı model tahmin edilmektedir. Daha sonra yapılan Engle Granger nedensellik ilişkisinde, Model 1 için ar-ge yatırım harcamalarından reel ekonomik büyümeye ve patent sayısının reel ekonomik büyümeye tek yönlü nedensellik ilişkisi olduğu sonucuna ulaşılmıştır. Model 2'de ise; ihracattan ar-ge yatırım harcamalarına, patentten ihracata ve endüstriyel tasarımlardan ihracata doğru tek yönlü nedensellik ilişkisi belirlenmiştir. Son olarak, daha gelişmiş bir test olan Hatemi-J asimetrik nedensellik analizine göre, Model 1'de Ar-Ge yatırım harcamaları ve patentten reel ekonomik büyümeye pozitif bir nedensellik ilişkisi belirlenmiştir. Ayrıca model 1'de reel ekonomik büyümeden ar-ge yatırım harcamalarına, patent ve endüstriyel tasarımdan reel ekonomik büyümeye doğru negatif tek yönlü bir ilişki belirlenmiştir. Model 2'de ise; ihracat ile Ar-Ge yatırım harcamaları arasında çift yönlü bir nedensellik ilişkisine ulaşılmıştır. Ayrıca Model 2'de patent ve endüstriyel tasarım değişkenlerinden ihracata doğru negatif bir nedensellik ilişkisi tespit edilmiştir.

In Turkey Economy Analysis of the Relationship Between R & D Investment Expenditures, Patent, Industrial Design, Exports and Real Economic Growth

In this study, relationship between R & D investment expenditures, number of patents, industrial designs exports and real economic growth are analyzed in the period from 2000-2019 for Turkey. First in this study, ıt is applied Zivot-Andrews structural break test. Secondly, ıt is analyzed the existence of cointegration relationship between series by Engle-Granger cointegration test. Thirdly, the causality relationships between the series are tested, and for this, Engle Granger and Hatemi-J asymmetric causality test are used. In this study are estimated two different models. In the Engle Granger causality relationship made afterwards, the singletrack causality relationship from R&D investment expenditures to real economic growth and the number of patents to real economic growth has been determined in Model 1. In Model 2, one-way causality relationship is determined from exports to R&D investment expenditures, from patent number to exports and from industrial designs to exports. Finally, according to a more advanced test, Hatemi-J asymmetric causality analysis, a positive causality relationship from R&D investment expenditures and patent to real economic growth are determined in Model 1. In addition, in model 1, a one-way relationship has been determined between negative components from real economic growth to R&D investment expenditures and patent and negative components from industrial design to real economic growth. In Model 2, a bidirectional causality relationship between exports and R&D investment expenditures have been reached. In addition, a negative causality relationship between patent and industrial design variables towards export have been determined.
