This study aims to investigate the impact of R&D expenditures, energy consumption, and human capital on regional economic performance in level 1 regions in Turkey, using a random coefficient panel model. Annual data for the period 2010-2021 for level 1 regions were used. Regional gross domestic product, which is representative of regional economic performance, was used as the dependent variable. Regional electricity consumption, R&D expenditures, and the proportion of the workforce with higher education were used as independent variables. The study used panel data analysis methods, including horizontal panel dependency, panel unit root test, homogeneity, and random coefficient panel. According to the panel results of the random coefficient panel data model, all independent variables have a statistically significant and positive effect on the regional gross domestic product at a 1% level of significance. The cross-sectional results of the study indicate that R&D expenditures have a positive and significant effect on regional gross domestic product in many regions.

Anahtar Kelimeler

AR-GE HARCAMALARININ, ENERJİ TÜKETİMİNİN VE BEŞERİ SERMAYENİN BÖLGESEL EKONOMİK PERFORMANS ÜZERİNDEKİ ETKİSİ

Öz

Bu çalışma, Türkiye’deki düzey 1 bölgelerinde AR-GE harcamalarının, enerji tüketiminin ve beşeri sermayenin bölgesel ekonomik performans üzerindeki etkisini rassal katsayılı panel modelini kullanarak araştırmayı amaçlamaktadır. Düzey 1 bölgelerine ait 2010-2021 dönemi için yıllık veriler kullanılmıştır. Bağımlı değişken olarak bölgesel ekonomik performansın temsilcisi olan bölgesel gayrisafi yurt içi hasıla kullanılmıştır. Bağımsız değişkenler olarak bölgesel elektrik tüketimi, AR-GE harcamaları ve beşeri sermeyenin temsilcisi olan yükseköğretim mezunu iş gücü kullanılmıştır. Yatay kesit bağımlılığı, panel birim kök testi, homojenlik ve rassal katsayılı panel veri analiz yöntemleri kullanılmıştır. Rassal katsayılı panel veri modelinin panel sonuçlarına göre tüm bağımsız değişkenlerin %1 önem düzeyinde istatistiksel olarak anlamlı ve pozitif bir biçimde bölgesel gayrisafi yurt içi hasılayı etkilemektedir. Çalışma modelinin kesit sonuçları, birçok bölgede AR-GE harcamalarının bölgesel gayrisafi yurt içi hasıla üzerinde pozitif ve anlamlı etkisinin olduğunu ortaya koymuştur.
