摘要

摘要本研究推断了农业贸易开放、全要素生产率增长和国内农业支持对非洲粮食安全的影响。为了在存在复杂误差项的情况下保持估计的效率和一致性，我们对13个非洲国家2005-2016年的面板数据采用了面板校正标准误差（PCSE）估计量。结果表明，农业贸易自由化和全要素生产率具有显著的有利影响。此外，我们发现，将农业支持减少到无扭曲水平之外，可以加强粮食安全。在贸易开放的基础上，我们呼吁以出口增长为导向的国内支持，以农业人力资本开发、创新和研发为基础。

Agricultural trade liberalisation, agricultural total factor productivity growth and food security in Africa

ABSTRACT The study draws inference on the impact of agricultural trade openness, total factor productivity (TFP) growth, and domestic agriculture support on food security in Africa. To retain estimates efficiency and consistency in the presence of complex error terms, we employed the Panel-Corrected-Standard-Error (PCSE) estimator on panel data spanning 2005–2016 for 13 African countries. Results suggest that agricultural trade liberalisation and TFP have significant and favourable effects. Moreover, we find that reducing agricultural support beyond distortion-free levels enhances food security. Further to trade openness, we call for export growth-oriented domestic support anchored on agricultural human-capital development, innovation, and research and development.
