本文旨在评估参与全球市场自由化进程的一组地中海国家农业部门的技术效率。该分析将随机生产前沿模型应用于一组六种不同的农作物产品。对于每种产品，均使用涵盖 14 个地中海国家 1990 年至 2005 年期间的面板数据集，并获得单独的计量经济学结果。然后在第二阶段使用横截面国家信息来评估导致技术效率低下的主要因素并解释地中海国家之间的效率差异。实证结果表明，地中海农业生产存在严重的低效率问题，而且不同国家和作物之间存在显着差异。欧盟国家的平均技术效率水平似乎高于SMC，其中阿尔及利亚、摩洛哥、突尼斯和约旦等一些国家存在严重的资源错配。研究结果表明，通过扩大灌溉面积、鼓励农民机械化和解决土地细碎化问题，一些地区的农作物产量还有提高50%的空间。
This paper aims to estimate the technical efficiency of the agricultural sector in a group of Mediterranean countries involved in the process of global market liberalization. The analysis applies the stochastic production frontier model to a set of six different crop products. For each product, a panel data set covering the period 1990-2005 in fourteen Mediterranean countries is used and separate econometric results are obtained. Then cross-sectional country information is used, in the second stage, to assess the main factors contributing to technical inefficiencies and to explain efficiency differentials among Mediterranean countries. The empirical results revealed the presence of important inefficiencies in Mediterranean agricultural production with significant diversities across countries and crops. EU countries on average appear to have higher technical efficiency levels than SMC, among which some states such as Algeria, Morocco, Tunisia and Jordan display substantial misallocation of resources. The results indicate that there exists scope for increasing crop production up to 50% in some regions through expanding irrigated areas, encouraging the mechanisation of the farmers and combating the land fragmentation.
