Abstract

This study aims to measure the total productivity of agricultural production factors through the calculation of the Malmquist index for six Mediterranean countries during the period 2003-2018. The results indicate that the growth of agricultural productivity in the Mediterranean region during this period by the calculation of the Malmquist index recorded an increase of 13.2%. Much of this productivity growth is driven by technological change rather than a change in technical efficiency or scale. In fact, the technology change increased by 13%, while the technical efficiency change showed a slight increase of 0.2% due to the scale efficiency change of the same percentage. It should be noted that the total productivity of agricultural production factors and the contribution of technical change and scale efficiency have the same trend at the subregional level, but are different at the country level. These results show that the total productivity of agricultural production factors is highly variable between Mediterranean countries and that the overall efficiency gains obtained are largely due to the phenomenon of technological catch-up rather than to gains in scale or efficiency pure.

利用马尔姆奎斯特指数方法计算地中海地区的总农业生产力

本研究旨在通过计算2003-2018年期间六个地中海国家的Malmquist指数来衡量农业生产要素的总生产力。结果表明，根据Malmquist指数计算，这一时期地中海地区的农业生产力增长了13.2%。这种生产力增长很大程度上是由技术变革驱动的，而不是技术效率或规模的变化。事实上，技术变化增加了13%，而由于相同百分比的规模效率变化，技术效率变化略有增加0.2%。应当指出，农业生产要素的总生产力以及技术变革和规模效率的贡献在次区域一级具有相同的趋势，但在国家一级有所不同。这些结果表明，地中海国家之间农业生产要素的总生产率变化很大，所获得的总体效率收益很大程度上是由于技术追赶现象，而不是纯粹的规模或效率收益。

期刊介绍： New Medit is an applied economics journal, with a multidisciplinary approach, aimed at providing insights into the economic and the social transformations of agro-food sector, rural societies as well as local development and bioeconomy in the Mediterranean Basin. Manuscripts submitted to NEW MEDIT generally should deal with wide-ranging topics that can be extended to other countries where organisational, production and market conditions and the related development policies may emerge at the corporate or regional level.
