“…For this research, we have selected 46 municipalities and cities (LAU1) with a population of more than 50,000 inhabitants (Appendix C), of the total 103 municipalities and 216 cities in Romania (Figure 1). These cities are the major economic hubs of the country [42][43][44], especially the capitalthe Municipality of Bucharest-the sixth city in the EU in terms of population (2,131,034 inhabitants in 2019), followed by six regional centers with a population exceeding 300,000 inhabitants: Iași (378,954 inhabitants), Timișoara (328,186 inhabitants), Cluj-Napoca (324,960 inhabitants), Constanța (313,021 inhabitants), Galați (304,050 inhabitants), and Craiova (301,269 inhabitants) [45]. With an important rural population (around 48% of the total population), the major municipalities of Romania are the leading places for innovation and smart city solutions, connecting large rural hinterlands with the global flow of capital, goods, and information [46,47].…”
