Regional disparities, transmission channels and country's economic growth
研究了欧盟国家内部区域差异如何通过人力资本和投资等传导渠道影响国家经济增长，发现总体区域差异抑制增长，但人力资本和投资的区域差异反而可能促进增长。
Abstract Regional disparities reflect the development pattern in many countries. Rich regions or prosperous cities confirm the unbalanced nature of economic growth. However, there is the lack of studies undertaking the role of regional stratification in the national economy. This study explores the transmissions channels through which regional disparities may affect the country's growth. A system or recursive equation by means of the control function approach (CFA) was applied to empirically assess the weight of these mechanisms. The level of regional disparities within the EU countries at nomenclature of territotial units for statistics‐2 level was calculated applying economic polarization measures. Empirical results, based on panel data analysis, showed that overall regional disparities affect negatively growth. However, after exploring transmission channels of this relationship, it was shown that regional differences in human capital or investments may enhance growth at the national level. The results were robust to various estimation methods.
