- ItemCapital-Labor-Output Nexus in Türkiye's Fisheries Sector: Panel ARDL Analysis(Isparta University of Applied Sciences, 2025-09) Şengül, Serkan; 355807This study analyzes the relationship between production, labor force and capital investments in the fisheries sector in the Marmara, Aegean, Mediterranean, Western Black Sea and Eastern Black Sea regions of Türkiye and examines their effects on sectoral growth and employment. In the study, total fish production, number of employees in the sector and capital investments (number of vessels) variables are used in the panel data analysis covering the period 2006-2023. According to the results of the analysis, the labor force has a positive and significant effect on production, but the effect of capital on production is negative. This shows that capital investments in the Turkish fisheries sector have not been able to provide the expected productivity growth. Moreover, capital investments are found to support employment by increasing labor demand. The long-run cointegration results reveal a strong equilibrium relationship between the variables. This study contributes to the existing research in the literature and provides strategic recommendations for the development of sustainable growth and productivity policies in Türkiye's fisheries sector. In particular, supporting aquaculture activities, modernizing capital investments and taking regional differences into account are critical for the long-term sustainability of the sector.
- ItemGıda Güvenliğinin Ekonomik ve Çevresel Belirleyicileri: BRICS-T Ülkeleri İçin Bir Analiz(Dokuz Eylül Üniversitesi, 2025-07) Şengül, Serkan; Köprücü, Yılmaz; 355807Bu çalışma, BRICS-T ülkelerinde gıda güvenliğini etkileyen ekonomik ve çevresel faktörlerin uzun dönemli etkilerini analiz etmektedir. Çalışmada, gıda güvenliği endeksi, karbon emisyonları, kişi başına düşen gelir, nüfus artış oranı, ve enflasyon değişkenleri incelenmiştir. Panel eşbütünleşme testi ve FMOLS yöntemleri kullanılarak, karbon emisyonlarının gıda güvenliği üzerinde pozitif bir etkisi olduğu, ancak bu etkinin çevresel sürdürülebilirlik açısından risk oluşturabileceği tespit edilmiştir. Bulgular, sürdürülebilir tarım teknolojilerine yatırım yapılması, doğal kaynakların korunması ve uluslararası işbirliklerinin artırılması gerektiğine işaret etmektedir. Çalışma, BRICS-T ülkelerinin farklı ekonomik ve çevresel koşulları ışığında literatüre yeni bir bakış açısı sunmaktadır.
- ItemProduction and Sustainability in Türkiye's Fisheries Sector: The Role of Economic Variables(Çanakkale Onsekiz Mart University, 2025-07) Şengül, Serkan; 355807This study investigates the impact of basic economic variables on production processes in Türkiye's fisheries sector, emphasizing sustainable development strategies. Using a dataset from the Turkish Statistical Institute covering annual data from 2003 to 2023, the research employs the ARDL model to examine the long-term and short-term effects of capital investments, labor costs, and energy expenses on total production. Results indicate that capital investments significantly enhance productivity, though misallocation can negatively impact efficiency. Labor and energy costs exhibit a negative effect, underlining the importance of cost optimization for sectoral sustainability. Based on these findings, the current study proposes strategic policy recommendations such as; efficient capital allocation, labor cost optimization through training programs, and the adoption of renewable energy sources to reduce operational expenses. These recommendations aim to support sustainable growth in the Turkish fisheries sector, enhance food security, and bolster economic resilience.
- ItemFrom capture to culture: the asymmetric impact of education on Türkiye's fisheries sector(Springer, 2025-08) Canbay, Şerif; Şengül, Serkan; Karahan Dursun, Pınar; 355807; 414023The aim of this study is to analyze the causal effect of the net schooling rate, as a proxy for human capital, on saltwater fisheries and aquaculture in five coastal regions of T & uuml;rkiye (Marmara, Aegean, Mediterranean, Western Black Sea, and Eastern Black Sea). In the empirical analysis, we use the panel data for the period 2009-2022 and employ the dependent variables that are the amount of fish production obtained through fishing in Model 1 and the amount of fish produced through aquaculture in Model 2. The study applies the panel bootstrap Granger causality method, considering both structural heterogeneities and cross-sectional dependencies. The results show that the effect of educational attainment on fish production activities varies both by type of production and by regional conditions. In the Mediterranean and Aegean regions, educational attainment has strong effects on both fishing and aquaculture, while in some regions, it has a negative effect on production. The study contributes to the literature by presenting the effects of education, a socio-economic variable, at the sectoral level in detail; it also provides an empirical basis for the development of region-specific sustainability policies.
- ItemEconomic growth and fisheries biocapacity in BRICS+T: An Environmental Kuznets Curve analysis(Ege University, 2025-03) Canbay, Şerif; Şengül, Serkan; 278780; 355807This study evaluates the robustness of the Environmental Kuznets Curve (EKC) hypothesis by examining the association between economic growth and fisheries biocapacity in BRICS+T countries, namely Brazil, Russia, India, China, South Africa, and Türkiye. Panel bootstrap causality test is utilized to evaluate the causal relationship between the variables using data covering the period 1992-2022. The results show that the EKC hypothesis is held for Russia, South Africa and Türkiye and that economic growth initially causes to a decrease in fisheries biocapacity, but after a certain threshold, biocapacity recovers. In contrast, the EKC hypothesis is not supported for Brazil, China and India. These findings necessitate governments to take policy measures to promote environmental sustainability.
