Analiz, 1992-2022 yılları arasındaki veriler kullanılarak Kesirli Fourier Birim Kök Testi ile gerçekleştirilmiştir. Analize 31 OECD ülkesi dahil edilmiştir. Bulgular, çevre teknolojileriyle ilgili patentlerin 23 ülkede OECD ortalamasına yakınsadığını göstermektedir. 8 ülkede yakınsama görülmemektedir. Ülkelerin yaklaşık %75'inde yakınsama olduğu göz önüne alındığında, ortak bir politika izlenmesinin olumlu sonuçlar verebileceği söylenebilir. Ancak yakınsamanın olmadığı 8 ülke göz önüne alındığında, bu ülkelerin ortak stratejilerin yanı sıra ek, ülkeye özgü politikalar geliştirmeleri yararlı olacaktır.

Analysis was conducted using Fractional Fourier Unit Root Tests using data from 1992 to 2022. Stochastic convergence was used, and 31 OECD countries were included in the analysis. The findings indicate that patents related to environmental technologies converge to the OECD average in 23 countries. Convergence is not observed in 8 countries. Given that convergence exists in approximately 75% of countries, it can be said that pursuing a common policy could yield positive results. However, considering the 8 countries where convergence is not present, it would be beneficial for these countries to develop additional, country-specific policies alongside common strategies CR - Acemoglu, D., Aghion, P., Bursztyn, L., & Hemous, D.
