Based on data drawn from the national section of the EU Farm Accountancy Data Network (FADN) database, the study investigates the efficiency of a panel sample of Italian farms practising other gainful activities. An output-oriented Data Envelopment Analysis is performed for each year from 2012 to 2017. A second step of analysis is carried out by using the Malmquist Index in order to analyse inter-temporal productivity changes and to decompose its variation into three components, that is, the variations in pure technical efficiency, the variation in scale efficiency and the technological progress for every two years. Results show there is much room for improving the performances of diversified farms, even when considering the variability observed among farms in terms of efficiency scores and across the investigated period. Some variables at contextual and farm levels – farm's location and size– relate to the efficiency performances of diversified Italian farms. Over the investigated period of time, the technological change supports farms' performances and contrasts some situations of low managerial efficiency.

分析多元化农场的效率：来自意大利 FADN 数据的证据

该研究基于欧盟农场会计数据网络（FADN）数据库国家部分的数据，调查了意大利农场开展其他有酬活动的小组样本的效率。对2012年至2017年每年进行面向产出的数据包络分析。第二步分析是利用Malmquist指数进行分析，分析跨期生产率变化，并将其变化分解为三个组成部分，即、纯技术效率变化、规模效率变化和每两年的技术进步。结果表明，即使考虑到农场之间在效率得分方面和整个调查期间观察到的变异性，多元化农场的绩效仍有很大的改进空间。背景和农场层面的一些变量——农场的位置和规模——与多元化意大利农场的效率表现相关。在调查期间，技术变革支持了农场的绩效，并对比了一些管理效率低下的情况。
