The aim of this study is to analyse the extent to which different productive factors, and the relationships that exist between them, affect the economic growth of productivity in ten Middle Eastern and North African ( MENA ) countries during the period 1990-2010. A translog production function is estimated by using panel data and the contribution of the factors to growth is calculated. The results show a positive effect of the physical and human capital on productivity and high complementarity relationships between them, both factors being essential in determining economic growth. However, the magnitude of their contribution varies substantially between the ten countries considered. Thus, the capitalisation of the economies and the improvement of the human capital seem to be key policy elements of economic growth in these countries. Nevertheless, a considerable part of the economic growth cannot be explained by these factors, particularly in Syria, Jordan, Saudi Arabia and Tunisia.

中东和北非国家生产要素对经济增长的不同贡献

这项研究的目的是分析1990-2010年期间，十个中东和北非（MENA）国家不同生产要素及其之间存在的关系对生产率经济增长的影响程度。通过使用面板数据估算超数生产函数，并计算因素对增长的贡献。结果表明，物质资本和人力资本对生产力及其之间的高度互补关系具有积极影响，这两个因素对于确定经济增长至关重要。但是，在所考虑的十个国家之间，其贡献的大小差异很大。因此，经济资本化和人力资本的改善似乎是这些国家经济增长的关键政策要素。不过，
