This work proposes an alternative measure of court performance, namely, time efficiency, which is equal to the length of a verdict divided by the time needed to resolve the case. Using the data of resolved judgments of the Court of Justice of the European Union (CJEU) from 1954 to 2017, we show that, first, backlog causes time efficiency to fall using a vector autoregression model (VAR), and, second, the lowest value of time efficiency coincides with the establishment of the General Court in 1989. We argue with evidence that the improvement of time efficiency since 1989 was a result of the reform of the CJEU.

时间效率作为法院表现的衡量标准：来自欧盟法院的证据

这项工作提出了另一种衡量法院表现的方法，即时间效率，它等于判决的长度除以解决案件所需的时间。使用欧盟法院 (CJEU) 1954 年至 2017 年已决判决的数据，我们表明，首先，积压导致使用矢量自回归模型 (VAR) 的时间效率下降，其次，最低时间效率的价值恰逢 1989 年普通法院的成立。我们论证了自 1989 年以来时间效率的提高是欧洲法院改革的结果。
