Zróżnicowanie poziomu wydajności pracy i jego przyczyny w polskich województwach w latach 1998-2008
Differentiation of Productivity Levels and its Causes in Polish Voivodeships in the Years 1998-2008

Summary/Abstract: The present article aims to determine which factors contributed most to a differentiation of productivity levels of Polish voivodeships in the years 1998-2008. The author applied a non-parametric DEA method (Data Envelopment Analysis) and the Malmquist productivity index. The use of the latter allowed the author to distinguish three components of changes in productivity: changes in relative efficiency, technological progress and accumulation of real capital. As a result, sources of changes of productivity in the studied time period were found and recommendations for regional policies were formulated.
