We aim to investigate the effect of Single Market Programme on the spatial interaction of labour income share amongst the EU countries. Spatial panel data analysis is used for the aim of the study. The dataset is obtained from AMECO and WDI databases and covers the time period of 1960–2017. The results show that sign of spatial interaction between these countries in term of the labour income share has turned from positive to negative after the Single Market Programme. In other words, the Single Market Programme has induced to decrease the labour income share by negatively affecting the spatial interaction between these countries. In addition, we find that although the negative impacts of capital-output ratio and trade openness on the labour income share decrease, the negative impact of total factor productivity increases after the Single Market Programme. The results of robustness check also confirm our empirical findings.

我们旨在调查单一市场计划对欧盟国家间劳动收入份额空间互动的影响。空间面板数据分析用于研究目的。该数据集来自 AMECO 和 WDI 数据库，涵盖了 1960-2017 年的时间段。结果表明，在单一市场计划之后，这些国家之间在劳动收入份额方面的空间互动迹象已由正转为负。换句话说，单一市场计划通过对这些国家之间的空间互动产生负面影响，导致劳动力收入份额下降。此外，我们发现虽然资本产出比和贸易开放对劳动收入份额的负面影响有所下降，单一市场计划后全要素生产率的负面影响增加。稳健性检验的结果也证实了我们的实证结果。
