[Retracted] Can European Union (EU) Enlargement Boost Regional Economic Common Growth? Multi‐Period Difference‐in‐Difference (DID) Method

Abstract

Under the dual background of Britain’s blatant “Brexit” and the steady “expansion” of the European Union (EU) audit list, the economic effect of the development of regional alliances, in the end, is a question worthy of in-depth discussion. Using data from a sample of 27 EU member states from 2000 to 2018, this study examines and compares the impact of EU enlargement on economic growth for countries as a whole, developed and developing countries, and Central and Eastern European (CEE) countries using a multi-period difference-in-difference (DID) method and explores the mechanisms underlying that. The results show that EU enlargement contributes to the expected regional economic growth, and the effect is more evident in developed countries and CEE countries; the robustness of the results is tested by the dynamic effect test and counterfactual method; EU enlargement improves the spatial allocation of factor markets through regional integration, increases productivity, and positively promotes the overall national economic growth. As a typical quasi-natural experiment of the development of regional integration, the research results of this study on the enlargement of the EU provide a useful reference for the promotion of the development of cross-administrative integration around the world.

Trends in the development of the national economy as a medium for the functioning of Ukrainian organizations

“…country, but with a delayed effect, which can be used in the process of forecasting and achieving the desired level of GDP. In [26], the results of the study of the impact of EU enlargement on the socio-economic development of the member countries are presented.

“…Scientists also insisted on the positive role of European integration in promoting regional economic growth, increasing the production efficiency of member countries and releasing their potential. The concept of the siphon effect of developed and central regions on remote and developing regions introduced by the authors [26] determines the feasibility of taking effective measures for new EU member states aimed at avoiding the outflow of labor, capital and other factors of production.…”

The influence of knowledge-intensive service industry agglomeration in the Yangtze River Delta urban agglomeration on regional economy

“…Some related documents suggest that the position and function of knowledge-intensive service industry in regional economic development are mainly reflected in the following aspects: knowledge-intensive service industry is the core and focus of regional economic industrial development; Knowledge-intensive service industry has promoted the upgrading of regional industrial structure; The knowledge-intensive service industry has stimulated the employment of local workers; Knowledge-intensive service industry provides all-round support for the development of new industrialization. Zhao X, Shi C and Li Y proposed in their research in 2022 that knowledge-intensive service industry has the industrial characteristics of long accumulation, high added value and high driving force, which has a strong radiation and driving effect on regional economy, and its extended industrial chain and service industrial chain will drive the development of regional economy and society [ 4 ]. Before 2008, Dai W also mentioned in his research: In the industrial chain of regional economy, there is a dialectical relationship among the three major industries, which are mutual conditions, preconditions and “upstream industries”.…”
