The article discussess the concepts of restructuring and reconversion of the national economy. These are difficult and complex problems, and their implementation takes a long time both at the preliminary and the execution stage. The labour market is a component of the restructuring process. It has been found out that this market is quite differentiated in particular administrative provinces of Poland. There is needed a coordination of studies on the restructuring process, the labour market and unemployment. It also appears necessary to intensify such studies on the macro scale (i.e. that of the entire country) and in regional cross-sections. More attention has been given in the analysis to the restructuring process taking place in the regions of Łódź, Wałbrzych and Silesia. The industries in these regions have been classified as the so-called sunset industries, which must be partly liquidated and deep structural changes must be caried out there. It is pointed out in the article that the analysis of delimitation of labour markets calls for their adjustment to real needs, which should reflect the situation existing in this field. The diversification of labour market is determined by the level of socio-economic development. The article postulates that there should be determined the degree to which labour statistics reflect the requirements of researches and analyses.
