At the beginning of the 21st century, ever faster growth was recorded by the digital economy, which proved to be seven times faster than the rest of the economy. Through digital networks that support the economy and parts of our business and private lives, Europe lags behind for other countries in the world. The facts that underscore this lack of potential are: uneven business systems between Member States, high fees for telecommunications operators in cross-border communication, roaming (which has only recently been minimized), and uneven connectivity of digital networks that support private and business life, between EU countries . The digital plan launched by the EU in May 2010 seeks to boost the European economy by providing sustainable economic and social benefits of a single digital market. The aim of this paper is to explore and describe the role and importance of the Digital Plan for the Republic of Croatia through the establishment of a single digital market, enhancing interoperability, enhancing trust in online commerce, promoting fast and ultra-fast internet, investing in research and development and promoting digital literacy. The contribution of the broadband internet to digital citizenship, increasing the efficiency of cross-border connectivity through the achievement of a single telecommunications market, the impact on e-business, the protection of cybernetic attacks and the reduction of costs through the introduction of a single digital market, the impact of information communication technologies on the achievement of the Digital Plan's goals and the impact of the Digital Plan on Development, innovation and digital research are research questions that have been tried to give an answer to the work. The research used the literature of domestic and foreign authors from online databases and the literature of the Zadar City and University Library. The theoretical framework of the work was supported by scientific papers and methods of analysis, synthesis and systematization were used, while the empirical part of the paper used the EU Reports and secondary data sources. The research suggests that the implementation of the Digital Plan should contribute to better cross-border connectivity, better cross-border prices, greater innovation and diversification of products and services through the development of fast networks or the introduction of broadband internet, which should contribute to greater digital citizenship, greater consumer rights, for roaming in the EU and increasing security for investors. At this point, e-commerce in the EU is still underdeveloped, but a series of initiatives should change in the coming years. ICTs are developing and with this development increasingly and more intensively contribute to the greater development of knowledge, skills and market opening to global business and thereby achieving the goals of the Digital Plan. The Digital Plan has a major impact on development, innovation and digital research, as it promotes and supports their progress as they are one of the drivers and foundations for a better and better quality of life for all citizens.
