Makineler ve İhracat: Tarımsal Verimliliği Destekliyor mu, Engelliyor mu?

Öz

Bu çalışma, tarımsal mekanizasyon, gıda ihracatı, kişi başına düşen gelir ve beşeri sermaye gelişiminin tarımsal verimlilik üzerindeki etkilerini incelemektedir. 2000-2019 yıllarını kapsayan 55 gelişmekte olan ülkeye ait panel veriler kullanılarak, heterojenlik ve kesitler arası bağımlılığı dikkate alan AMG ve CCE-MG yöntemleri uygulanmıştır. Elde edilen bulgular, tarımsal mekanizasyonun verimlilik üzerinde beklenenin aksine negatif bir etkiye sahip olduğunu ortaya koymaktadır. Bu durum, altyapı eksiklikleri, finansmana erişim zorlukları ve küçük ölçekli çiftçilerin teknolojiye adaptasyonundaki yetersizliklerle açıklanabilir. Öte yandan, kişi başına düşen gelirin tarımsal verimliliği artırdığı görülmektedir; bu, ekonomik büyümenin modern tarımsal tekniklerin benimsenmesini teşvik ettiğini göstermektedir. Gıda ihracatının ise tarımsal verimliliği artırdığı tespit edilmiştir; ancak, dış pazarlara aşırı bağımlılığın fiyat dalgalanmalarına ve gıda güvenliği risklerine yol açabileceği unutulmamalıdır. Beşeri sermayenin (eğitim) etkisi ise karmaşık bir tablo sergilemektedir; genel eğitim seviyesinin artması kırsal iş gücünün tarım dışı sektörlere kaymasına neden olabileceğinden, eğitimin tarım odaklı becerilerle desteklenmesi gerekmektedir. Bu bulgular, gelişmekte olan ülkelerde tarımsal verimliliği artırmak için çok yönlü bir politika çerçevesinin gerekli olduğunu göstermektedir.

Machines and Exports: Do They Complement or Counteract Agricultural Productivity?

Abstract

This study examines the impact of agricultural mechanization, food exports, per capita income, and human capital development on agricultural productivity. Utilizing panel data from 55 developing countries covering the period 2000–2019, the analysis employs the AMG and CCE-MG estimation techniques, accounting for heterogeneity and cross-sectional dependence. The findings reveal that agricultural mechanization, contrary to expectations, has a negative impact on productivity. This may be attributed to inadequate infrastructure, limited financial access, and smallholder farmers' difficulties in adopting new technologies. In contrast, per capita income positively influences agricultural productivity, indicating that economic growth facilitates the adoption of modern agricultural practices. Food exports also enhance productivity, though excessive reliance on external markets may introduce risks related to price volatility and food security. The effect of human capital (education) presents a more complex picture; while higher education levels are generally associated with increased efficiency, they may also drive the rural workforce to shift to non-agricultural sectors. This underscores the need for education systems to incorporate agricultural-specific skills and technological training. These findings highlight the necessity of a comprehensive policy framework to enhance agricultural productivity in developing economies.
