In the original publication [1], there was a mistake in the legend for Figure 1 and Figure 4. A map legend can be explained either by text within the figure (where space permits) or by numbering the conventional signs within the figure, and explaining them below the figure (where space is more limited). In Figure 1 and Figure 4, the second method of explanation was initially used (by means of the numbers explained under the figure), but later, according to the indications received from the referents, the numbers in the figures were replaced by their explanations (according to the version uploaded on 3 September 2023). Due to an unfortunate error, in the version uploaded on 6 September 2023, Figure 1 and Figure 4 were uploaded with the conventional numbered signs in the legend, but without the explanation of the numbers below the figure, making the figures much more difficult to explain. Therefore, we request that these two figures be replaced with their variant, where the legend is explained in the text, as indicated by the referents. The correct legend appears below. The authors state that the scientific conclusions are unaffected. This correction was approved by the Academic Editor. The original publication has also been updated.

This paper intends to delve deeply into the current understanding of the ways in which the transition from a central-based economy to an economy relying on free competition has led to changes in the big urban centers, bringing about a change in the relationships with the suburban areas. The authors take into account the high population density, the lack of space, and the elevated price of land within the big cities, which leads to urban functions migrating beyond the administrative boundaries, thus favoring the process of suburbanization. Given the context, commercial forces shift, migrating from the center to the urban peripheries or even outside them. This research is based on a comprehensive process of participative investigation (2012–2022) in Bucharest, Romania’s capital city. The research relies on field investigation, statistical and quantitative analyses and bibliographical sources. The conclusions rely primarily on the idea that political changes cannot be separated from economic, cultural and environmental ones, highlighting globalizing flows and the development of big cities. Industrial activities, strongly developed within a central-based economy, have significantly declined, which is partly compensated for by the development of the tertiary sector and, in particular, of commercial services leading to a functional reconversion of the urban peripheries and of suburban areas. The conclusions suggest that it is very important to be highly careful regarding the dilemmas and challenges ensuing from uncontrolled urban growth; therefore, several measures of urban planning should be taken with a view to achieving a better cooperation between urban stakeholders and those from the metropolitan areas so as to attain some common objectives in infrastructure in order to reach an integrated regional development.
