西班牙在世界橄榄油生产和贸易排名中占据第一位。这一分析评估了该部门运作的相对技术效率。技术效率的概念对于衡量一个公司的业绩、确定采用创新技术的程度和总体生产效率至关重要。具体而言，本研究的主要目的是评估相对技术效率，并分解西班牙橄榄农场的生产力增长。技术效率的影响被假定为企业的具体特征的函数。最大似然法应用于模型的估计。采用一种原始方法将全要素生产率（TFP）增长分解为各个组成部分。结果表明，农场的位置，经理的年龄，以及劳动力的组成影响效率水平。技术效率变化和规模效应是影响全要素生产率增长的主要因素。
Spain occupies the first position in worldwide rankings of olive oil production and trade. This analysis assesses the relative technical efficiency with which this sector is operating. The concept of technical efficiency is critical to measuring the performance of a firm, determining the degree of innovative technology adoption and the overall production efficiency. Specifically, the main objective of this study is to assess the relative technical efficiency and to decompose the productivity growth of Spanish olive farms. Technical efficiency effects are assumed to be a function of firm-specific characteristics. Maximum-likelihood methods are applied to the estimation of the model. A primal approach is used to decompose total factor productivity (TFP) growth into its various components. Results indicate that farm location, age of manager, as well as the composition of the workforce affect efficiency levels. Technical efficiency changes and scale effects are found to be the main sources affecting TFP growth.
