The regional specialisation of sold production of industrial products was determined based on the value of the location quotient LQ, which indicates the level of regional specialisation in a given voivodship relative to the national level[1]. For each voivodship, PKWiU (Polish Classification of Products and Services) sections with the highest LQ values were identified.
To illustrate the changes over a five-year period, 2019 and 2023 were selected for comparison. The LQ indicators for PKWiU sections from these two periods make it possible to determine the direction of regional specialisation development. Data on sold production of industrial products used to calculate the LQ indicator are collected using the enterprise-based method, i.e., according to the seat of the enterprise.
[1] The indicator is called the location quotient or Florence’s concentration index.
