Divergence or Convergence: Growth Dynamics of Polish Regions

The purpose of this article is to establish whether regional convergence is present in Poland in terms of GDP per capita. An analysis was conducted for the years 1995–2005 at the voivodeship (NUTS2), sub-regional (NUTS3 classification) and intra-voivodeship levels. Convergence means a reduction of income disparities between regions. The opposite phenomenon is called divergence. The author of the paper used a method – proposed by Quah (1993, 1996a, 1996b) – that enables an analysis of the full distribution dynamics of relative per capita income. It consists in the estimation of transition matrices derived from Markov’s processes and in the use of nonparametric kernel estimators of the relative density function for relative GDP distribution per capita in subsequent years. The method facilitates verification of the club convergence hypothesis, which is impossible using the classic methodology (Barro and Sala-i-Martin 2003). It is clear that income distribution is stable and that there is no unconditional convergence both between voivodeships and between sub-regions. In general, voivodeships as well as sub-regions were impoverished as a result of a faster-than-normal growth of the richest voivodeships (mazowieckie voivodeship) and sub-regions (large cities, mainly Warsaw and Poznan). The diversification of relative GDP per capita grows in time both in the case of voivodeships and sub-regions. The convergence model that can be seen both at NUTS2 and NUTS3 levels is club convergence (polarisation): relatively the poorest and – separately – the richest regions are becoming similar and converge at different income levels. The analysis also includes the occurrence of sub-region convergence within voivodeships, with the only observable convergence model being club convergence.

Diversification of the level of economic development of cities and towns in the eastern region versus the diversification of the dynamics of changes

The aim of the paper is to analyze the level of economic development and its dynamics in the cities and towns in the eastern region between 1995 and 2015. The objects of the study were 54 cities and towns of the region. The source of the data for the analysis was the Local Data Bank of the Central Statistical Office. Taxonomic analysis, no-pattern method was used for the study. Ten variables were analyzed during the studied period. They were divided into those referring to budgets of municipalities/communes, national economy entities, and the labor market. As a result of the analysis, it was discovered that 50 cities and towns showed signs of development in the period. It was observed that the diversification of the level of economic development of cities and towns of the eastern region in the spatial layout did not decrease. It was also stated that the accession of Poland to the European Union had an impact on the growth of dynamics indexes of changes for the towns and cities.

Evolution of the economic base and economic growth of the towns and cities in the Warmińsko-Mazurskie voivodship

The author attempts to determine the size, structure and diversification of the economic base of towns and cities in the Warmińsko-Mazurskie Voivodship, as well as their evolution in the years 2008-2015. An additional objective is to determine the relationship between the level of economic growth of the examined units and the state of their economic base. The obtained results confirm the hypothesis that the economic sector is not a significant part of total employment in the surveyed units. At the same time, the exogenous employment structure is poorly diversified, and in the period under study it decreased even further, exposing local economies to external shocks. There is also a positive, although weak effect of the increase in local specialization on the level of revenue in local self-government units and on their level of unemployment.

Socio-demographic and spatial changes in the economic activity of rural population in Poland in 2010–2016

The paper analyses the changes in the scale of the rural economic activity and identifies their selected determinants. The socio-demographic characteristics of the labour resources and the economic differences between rural regions in Poland were analysed as reasons for the dissimilar levels of rural employment. Analyses have demonstrated that, in 2010–2016, rural economic activity measured by the employment rate increased from 50% to 53%, primarily as a result of the impact of cyclical determinants, reflected in the increase in the number of the employed being higher than the number of inactive persons, with a reduced scale of unemployment overall. The studies indicated similar values of the employment rate for urban and rural areas, while the differences in its level within the selected social categories were much more visible for rural populations. This reflected a persistence of territorial disparities in labour markets as well as a trend towards their convergence. The level of territorial differences in the rural employment in Poland was moderate and should be linked with regional economic characteristics. In this context, the allocation of rural labour supply could be attributed to the impact of cities and their functional areas and to the progress in economic diversification of villages located in a particular region. The discussion section of the paper outlines the institutional opportunities and barriers increasing rural economic activity. The presented conclusions were based on the Central Statistical Office data (mainly the Labour Force Survey and the Local Data Bank) and statistical and comparative analysis methods.

To Diversify or to Specialise? How to Strike a Balance in a Cluster Profile: A Case Study of the Hamburg Aviation Cluster (HAv), Drawing on Related Variety and Blending Processes

The motivation for this paper comes from the recognition that our understanding of specialisation might be too simplistic and that the dichotomy of specialisation and diversification could be outdated not reflecting the richness of real complex economic and technological relations among industries. Drawing on a qualitative study of the Hamburg Aviation (HAv) cluster, this paper discusses the peculiarities of a cluster profile in the digital time – the age of Industry 4.0 (I4.0), touching upon the issues of cluster structure and the complexity of production, synchronising specialisation with diversification, branching, and bridging, and the I4.0 attributes facilitating complementarity. The final research proposal, which is empirically embedded in the studied context, states that related variety encompassing both ‘specialisation in diversification’ and ‘diversification within specialisation’ can be further developed by a blending process. This can lead to branching and is modulated by the universal character of the I4.0 and a problem-solving attitude. It takes the form of an additive (new entries) or multiplicative (spinoffs) evolution, and, ultimately, owing to the complementarity, it can provide sustainable competitive advantages.
