- ItemAn Ardl Model Analysis Of Turkish Airlines’ Impact As A Carrier Power On Türkiye–Africa Trade Volume(Dokuz Eylul University, 2025-09) Sönmezay, Mine; 409821Türkiye has increased its presence in the continent by using transportation diplomacy as an effective tool within the scope of the African opening policy that it has initiated since the early 2000s. This study examines Türkiye’s economic power projection in Africa through transportation diplomacy. In the study, economic power projection through diplomacy is considered as a theoretical framework; the connections between Türkiye’s transportation infrastructure investments in Africa, the expansion of its flag carrier airline network and the increase in its trade relations are analyzed with quantitative data. In the study, time series analyses are conducted on Turkish Airlines (THY) data and Türkiye-Africa foreign trade volume. The analysis was carried out with annual data for the period 2001–2024. Before proceeding to model construction, the stationarity levels of the series were examined, then the ARDL (Autoregressive Distributed Lag) method was applied and diagnostic tests of the model were performed. In the last stage, Granger causality analysis was performed. The results show that trade volume, transportation capacity and destination network act together in a long-term relationship in Türkiye’s transportation-based economic engagement towards Africa. This situation shows that the expansion of transportation infrastructure supports the trade volume between the two countries. These findings reveal that transportation diplomacy is positioned not only as a supportive but also as a guiding and sustainable foreign policy tool in Türkiye’s economic interaction with the African continent. The sustainability of this policy, its institutionalization and concrete suggestions for policy makers are discussed in the conclusion section; strategic initiatives are suggested for Türkiye to become a more permanent and effective actor in Africa in line with its mediumsized power profile. The results show that THY’s passenger transportation capacity positively affects the trade volume in the short and long term.
- ItemTax Transparency, Knowledge and Awareness Dynamics in Cross-Border E-Commerce: The Case of Türkiye(Muhasebe ve Finansman Öğretim Üyeleri Bilim ve Araştırma Derneği, 2025-08) Sönmezay, Mine; 409821With digitalized trade, consumers encounter various tax liabilities in their purchases from different countries; this situation directly affects their decisions. This research aims to examine the tax factors affecting consumer behavior in the digitalizing global trade environment from a holistic perspective. In particular, the effects of tax-related knowledge level, awareness and transaction transparency perceptions on purchasing decisions in cross-border e-commerce were evaluated. Data were collected via an online survey with convenience sampling method between June 5–15, 2025 and analyzed with structural equation modeling (SEM). The findings revealed that only the Perceived Transaction Transparency variable had a significant and high level of effect on purchasing behavior. On the other hand, the direct effects of Tax Knowledge Level and Tax Awareness and Perception were not found to be statistically significant. This result suggests that the clarity and accessibility of tax-related information is more influential on consumer behavior than its mere presence.
- ItemProblems and solution suggestions related to logistics processes in cross-border e-commerce: evaluations towards e-export in Bursa province(Süleyman Demirel University, 2024-08) Sönmezay, Mine; Yıldırır Keser, Hilal; 409821Rapidly growing e-commerce, due to globalization and the impact of the Covid-19 epidemic, has significantly increased global demand, and cross-border e-commerce has become a frequently mentioned concept. Cross-border e-commerce, which also triggers the development of international trade, has begun to influence the economic policies of countries, especially with its e-export dimension. The most important factor behind the development and success of cross-border e-commerce can be expressed as being its logistics services. E-commerce processes achieve success with the effectiveness of these services. However, as in many countries, problems may occur in logistics processes in Türkiye, which may prevent cross-border e-commerce companies from using their potential. In this context, in the study, firstly, the concepts of e-commerce and cross-border e-commerce are discussed and the concept of e-export is clarified. Then, logistics services in cross-border e-commerce are explained. Finally, a qualitative research is conducted to reveal the logistics problems encountered in cross-border e-commerce, and the findings of in-depth interviews with companies engaged in e-export in Bursa are evaluated.
