摘要:In this study, the relationship between average economic growth (GDP) and average foreign direct investments of Belgium, Ireland, Luxembourg and Netherlands countries was investigated by using time series analysis and annual data of 2005-2018 period. Because, it was observed that these countries managed to attract foreign investments in different amounts to their countries by using the legal gaps in the European Union (EU) in this period and to continue their economic growth positively. These countries have also used the sovereign fields of other union member countries to reach the target, as well as their own geography. However, this method, which is claimed to be growth-oriented, has started to be discussed since 2013 and the activities regarding tax regulations have been examined by the European Commission. The argument that needs to be put forward today is whether these countries, which have been taken under surveillance by the European Commission, have gained foreign direct investment through non-legal means, which can be considered illegal in the last five years, and continue to contribute to their economic growth. It is beneficial to shed light on economic history with Regression and Granger Causality Analysis for the last fourteen years.
