Starzenie się społeczeństwa a wzrost gospodarczy w krajach Unii Europejskiej
Due to the still growing demographic aging process and the significance of this process on the economy, the article analyzes relationship between the demographic aging of the European Union countries and economic growth. The aim of the research was to determine the impact of demographic aging on the rate of economic growth in the EU27. The research period covered the years 2000-2015. Data from the Eurostat and the World Bank databases were used. The study adopted a division into the “old” and “new” EU Member States. The rate of GDP growth was taken as the measure of economic growth, while the measures of demographic aging included the old-age rate (percentage of population aged 65 or over) and the venerable senility rate (share of the population at the age of 80 or more in the general number of population). Panel models were used. It was found that the demographical aging of society negatively correlates with the dynamics of economic growth. In panel models constructed for countries of the "old" Union, regression coefficients for the old-age rate and the venerable senility rate were respectively: –0,446 and –1,521, while for the "new" EU countries were equal to: –0,153 (for the old-age rate) and –0,980 (for the venerable senility rate). This means that the negative impact of demographic aging on the GDP growth rate is more strongly observed in the countries of the "old" Union in comparison with the countries of the "new" Union.
