The European Union is by far the most important economic and development partner of the Republic of Moldova providing wide support for this young democracy to consolidate its fragile institutions. The main aim of this support is to improve the existing socioeconomic relations in the country and, therefore, encourage the development of Moldovan market economy. Nowadays, euro- sceptics in the Republic of Moldova as well as in other countries put under the question the efficiency and effectiveness of policies EU has promoted in neighbouring countries. Supported by obscure interests and widely covered by biased mass media, they distort public opinion and denigrate EU backed achievements in Eastern Europe, including in the Republic of Moldova. The present paper comes to bring an impartial insight and a disinterested view upon the role of EU in consolidating market economy in neighbouring countries considering the experience of the Republic of Moldova in this sense. The research takes into account reliable data-sources on the base of which it is performed the quantitative and qualitative analyses and are drawn coherent conclusions. The research through the use of economic analysis provides consistent arguments assessing the impact of EU support upon Moldovan market economy and its institutional framework.
