Nowadays, and generally speaking, EU funds include all EU programs, regardless of whether they are member states or countries outside the specified region or candidate countries. On the other hand, it is important to emphasize that EU funds are awarded year by year through various and numerous programs, for example with the purpose of cross-border cooperation, regional development of a particular area, education of all age groups, building of certain institutions and strengthening of the overall capacities. Accordingly, EU funds can also be interpreted as financial instruments serving the implementation of EU public policies, and are the primary basis for defining pre-defined and set goals. Also, EU funds aim to contribute to the achievement of key EU policies. Furthermore, as far as the territory of the Republic of Croatia is concerned, prior to accession to the European Union, "Instrument for Pre-Accession Assistance" (IPA), but after accession to the European Union in 2013, the most important source of funds becomes structural funds. Accordingly, it can be said that EU funds become the primary part of the investment of entrepreneurs in the territory of the Republic of Croatia and, as such, need to be exploited to the fullest extent. Namely, as mentioned in the previous section of the text, by the accession of 2013, numerous and significant financial opportunities and opportunities have been opened up to the Republic of Croatia, while only the use of EU funds has a number of development implications which are primarily reflected by the impact on the economy. In this way, efforts are made to act at regional level, ie the aim is to respect the numerous specifics of particular regions and regions. Accordingly, the aim of the regional development policy, which aims to contribute to the economic development of all parts of the European Union and also of the Republic of Croatia, needs to be emphasized.
