The goal of this paper is to analyse determinants of the performance of commercial district courts in Poland in the period 2009–2016 in terms of the number of resolved cases. To this end we apply a panel data approach to identify factors affecting court output (i.e. the number of cases adjudicated) and stochastic frontier analysis to investigate determinants of court efficiency in resolving cases. Although we found that the judicial system in Poland is mostly driven by the demand for justice, the results indicate that an increase in the number of judges can significantly enhance the number of resolved cases that require a full court trial. We also found that court efficiency is significantly associated with some auxiliary court staff members and variables capturing economic development of court jurisdiction. Specifically, we found that judge assistants increase court efficiency in resolving commercial cases requiring a full trial and court clerks boost court efficiency in resolving writ-of-payment cases.

法官和法院的绩效：波兰地方商事法院的案例研究

本文的目的是根据已解决案件的数量，分析2009年至2016年期间波兰商业区法院业绩的决定因素。为此，我们采用面板数据方法来确定影响法院产出的因素（即，判决的案件数）和随机前沿分析，以调查解决案件中法院效率的决定因素。尽管我们发现波兰的司法系统主要是由对司法的需求驱动的，但结果表明，法官人数的增加可以大大增加需要全面法庭审判的已解决案件的数量。我们还发现，法院效率与一些辅助法院工作人员和反映法院管辖权经济发展的变量显着相关。特别，
