The author restructured the abstract. Sentences were shortened in accordance with the recommendation that the authors consider revising them to no more than two sentences. The updated version of the abstract included the background, methodology, findings, and conclusion. The externalities are very important concepts in the research, and the mentioning of the externalities is reflected in the first sentence of the abstract. Here, by investigation, the authors explained this term in the introduction in the revised version in order to clarify the confusion. The researchers explained the impacts of externalities on the sustainable development of smart cities and territories. The explanation was disclosed with more details in the introduction. The authors provided clarification of what they mean by "The consequences of a social nature are much wider and deeper."The first paragraphs in the Methods section were moved to the Introduction. The introduction started from the second paragraph – The authors expanded the discussion on the methods once the first paragraph was deleted, enabling them to discuss the methods in detail. The references were extended by new recommended sources. The paper's novelty was revealed in Section 1. The authors suppose that market uncertainty affects the sustainable development of smart cities and territories. The requested changes are made accordingly in the revised version. The authors explained the mathematical model as part of management decision support. According to the experts, formalisation principles serve as the foundation for a mathematical model employed in the construction of smart areas. The results section's first two paragraphs were relocated to the techniques section. The results section contains the derivatives of what was proposed in the methods section. The final statement of the result analysis, explaining that computations were performed using Microsoft Excel, was relocated to the Methods section.

Several possible actions from a comprehensive perspective could be significant in Post-COVID recovery.1–4 The state as a whole, from the point of view of the economy, is a set of enterprises, both institutional and commercial. When studying economic processes at the top level, profits, common interests, and obligations must be taken into account.5,6 Additionally, it is important to introduce formalisms for the effect of externalities, which occur everywhere. Besides entrepreneurial activity, state institutions of the defense department, medicine, transport, education, etc., operate in each country. The authors define externalities as a cost or benefit that is imposed onto a third party that is not incorporated into the final cost (https://boycewire.com/externalities-definition/#Externalities-Definition). When modeling externalities, it is essential to consider both their positive (positive externalities) and negative (negative externalities) aspects based on the activities of all market entities. Positive externalities create a benefit to a third party. On the contrary, negative externalities generate a cost to a third party. For example, the digital transformation of smart cities and smart territories could positively affect achieving sustainable development’s environmental and social goals improving ecology and healthcare (two of ESG goals). The smart city concept enables the development of culture and society, the social inclusion of different kinds of urban residents in public services, and sustainability.
Any reaction can be the genesis in the general case. Therefore, considering the larger scale, it is necessary to not be limited to the field of ecology in smart cities and in the smart territories.7 The consequences of a social nature are much wider and more profound.8 Authors suggest including the indicators such as pollution, waste generation and consumption of water and energy. The authors consider the smart cities and territories concept as an efficient, green, socially inclusive socio-economic system using digital transformation to avoid a whole range of damage to a sustainable society. Such damage to society will first be taken into account when monitoring the economic indicators of the current activities of any market participants. Authors suspend that market uncertainty affects the sustainable development of smart cities and territories by forcing economic agents to reduce social responsibility’s expenditures.
As a rule, the analysis of market indicators uses the methods of surrogate markets. In turn, this direction, which is usually referred to as an indirect market method or proxy market, is divided into several pricing principles.
Authors suppose that, at present, there is no definitive methodology able to cover the problem in general. The researchers consider the novelty of the article applying the holistic approach with the dependencies of externalities in the form of a function and concerning the arguments as the characteristics of economic activity.9 An additional circumstance complicating any activity is the uncertainty of market conditions. Here, the stochastic process theory methods are used, making it possible to form adequate mathematical models.10 However, it must be taken into account that the indicators of distribution functions are not static. In solving the problem, a set of algorithms are defined, and the economic criteria used is justified. When evaluating a set of planned calculation results, special attention should be paid to finding a balance between the additional burden on the enterprise—i.e., on internalization and the profitability indicators of its activities. Based on this set of conditions, the formalisms of the mathematical model should be built. Similarly, non-commercial activities must be accounted for. This is necessary to assess the social factor in the activities of state institutions themselves in terms of their social and economic efficiency.
In this case, optimization is carried out by searching for the extrema of functionality, considering the inclusion of externalities in the market mechanism for evaluating performance. The results obtained may be a set of regulatory measures using institutional tools. These include dispositive, strategic, restrictive, and stimulating components that form the basis of administrative management and legislative acts that are implemented in both the concepts of preventive behavior and prevention of damage, as well as in the more general ideas of the preservation and development of the social environment.11
Improving the smart city concept is essential to meet the demand of growing urban conglomerates to maintain comfort12 and improve the quality of urbanization.13,14 Regulation of the internal flows of megacities is the main focus of maintaining the quality of urbanization.15 Ignoring environmental requirements to reduce landscape characteristics, which will occur without striving to maintain the structure and functions of the regional ecological system.16 Urbanization policy is closely related to a wide range of objectives, including transport policy, the provision of public infrastructure, and the provision of modern security and management facilities.17 Urbanization affects the condition and viability of green infrastructure and its maintenance as a source of ecosystem services, which will allow the development of effective policies for land use, sustainable urban development and infrastructure management.18 A recent study suggested the sustainable development of smart cities as a complex structure of interconnected organizations that influence the level of everyday life of the population.19
The authors developed a formalized description to solve the problem at hand. The methods presented in the literature operate, as a rule, with the tools of correlation and regression analysis.20 To find the optimal solution under the conditions of market uncertainty and to apply the optimization methods correctly, a more complex mathematical model is needed.
Since the processes of economic activity have some duration in terms of time and also have a complex nature based on changes in seasonal indicators, the authors used a combination of methods.21 Among them, we note the theory of the calculus of variations, methods for solving differential equations, the theory of mathematical games, and the main provisions5,6 of methods used for finding optimal control.22,23
In order to describe the processes under study, we introduce a number of parameters that describe business and government activities. The mathematical model we propose is based on the application of methods for finding optimal solutions.
We introduce the concept of the number () of enterprises. All of them work in this limited area. Let us take into account the fact that these enterprises have negative externalities as an external influence. In the case of additional costs for each enterprise, the effect of negative externalities can be reduced.
All calculations were implemented using Microsoft Excel (Microsoft, 2022) (RRID:SCR_016137).
We denote as the vector of searching for the optimal equilibrium solution. Searching for options for such solutions is carried out inside an -dimensional cube of economic situations. We make the calculation specific for , since in this case the result can be visualized. Let us enter the value of additional expenses . This amount reflects the need to spend additional money when planning work aimed at minimizing damage from the externalities produced.
Next, we take into account the possible differences in the scale of enterprises, such as the differences in damage and . We summarize the calculation model and data in Table 1.

To calculate, we assume that , and calculate the product of the vector below:
By applying the solution-finding rule24 to the formulated conditions, we obtain two inequalities. The calculated ratios reflect possible market equilibrium conditions. First, we need to define the conditions for the lower bound:
The next calculation step allows us to determine the upper limit:
We then carry out simple transformations and obtain the system:
The calculation process used for each enterprise is similar. As a result, one obtains a system of equations for calculating the boundaries necessary for making decisions:
All possible solutions are limited within the multidimensional cube of situations. The term of the multidimensional cube of situations means the visualization of several impacts on environmental and social goals considered as dimensions. Such visualization is applicable to the three-dimensional case considered in this example and is used solely for clarity. In the case of , this can be visualized in Figure 1. At the cube corners, the economic indicators associated with externalities are marked.
As a result of solving the system of equations, we obtain a set of regions for . The vector values belong to the multidimensional space of situations that satisfy the Nash equilibrium condition. The obtained data is represented in the simplest way by constructing volumetric diagrams of the solution in any package of mathematical applied programs. An analysis of the obtained equations shows that the domains of admissible solutions belong to the intersection of planes with hyperbolic surfaces.
The calculation results for the two participants in production activities are shown in Figures 2 and 3.38 The third solution differs only in terms of the orthogonal rotation of the axes in which the diagram is built.

Note that the equations are hyperbolic surfaces, with several intersection points giving the desired solution. To do this, it is sufficient, for example, to transform Equations (2) and (3) to the following form:
In this case, the variation in the boundaries forms multidimensional dependencies, as presented in Figures 2 and 3.
The first version of the result reflects a trivial solution . In addition to this case, it is possible to obtain stable states in two more variants. The calculation of the second vector makes it possible to determine the components that satisfy the equilibrium conditions:
Let us calculate the third case of equilibrium in a similar way. The desired vector is equal to:
Each calculated value is applied in different conditions. For the administration of cities and regions, the decision is made in order to overcome a number of barriers. This applies primarily to the disagreement between the profits of commercial structures, the negative externalities generated by their activities, and the social benefit of the population in the controlled territory. In the case of the dispositive method of legal regulation, the first (trivial) solution is applied everywhere.
This decision (presented in Figures 2 and 3) can be interpreted as the unwillingness of the participants in production activities to bear the costs of transforming external effects into internal ones.25
The second equilibrium solution accounts for restrictive measures. This approach requires the application of regulatory standards.
The third result of the decision involves the application of radical measures of restriction.
The listed measures have an economic character. The application of these restrictions obliges economic entities to conduct their activities while taking into account the interests of society. This will also generally affect the state of the entire economic system.26–30
It should be emphasized that the presented equations of the mathematical model reflect the situation for participants in commercial activities. This is explained by the fact that, in this case, it is possible to visualize the calculation results. The equations developed for the mathematical model can be scaled. At the same time, the number of participants31 in economic activities is not limited. In addition, the dependencies describing economic indicators can also have an arbitrary form. This only increases the dimension of the externalities model.
Authors’ recommendations for authorities and governments include suggestions to use the proposed mathematical model as part of the management decision support. The application of the obtained results in the organization of the life of modern megapolises is especially relevant. Due to the aggravated environmental situation, problems of both a social and economic nature are actively manifested in them. The effective work of the authorities will be based on a scientifically grounded methodology for solving problems related to the economics of the environment. Therefore, the efficient use of public resources is emphasized as among the major tasks that must be completed. The task of business analysis aimed at developing recommendations for authorities and governments is to take into account multidirectional processes. On the one hand, there is an increased burden on resources and a decrease in the quality indicators of these resources, and it is necessary to evaluate the negative externalities. For the economic indicators of the metropolis, the standard26 of living of the population depends on the activities of all types of businesses and on enterprises that create profit and employment. The results presented by the authors of this paper and the mathematical model32,33 make it possible to develop a solution algorithm. Based on this, it is possible to create expert systems. The development of large metropolitan areas and industrial centers is accompanied by data exchange flows. Modern big data technologies and statistical analysis provide operational, economic information for calculations based on mathematical models. Such systems are promising for use in the environmental, social, and corporate management of a smart city at the top level of planning. Also, the researchers propose making urbanization on the basis of sustainable development.
Urbanization reflects a global trend. Consolidation into large megapolises is based on a multifaceted process involving the development of society as a whole. Megapolises, alpha cities, and the neighborhoods of such agglomerations, at present, house up to half of the world’s population and the majority of industrial enterprises. The smart city concept has no alternative today. The set of expert algorithms within the framework of the smart city conceptual model is intended primarily for decision-makers in each of the sectors of the economy. The authors suppose that the principles of formalization are used as the basis for a mathematical model. As a result, the development of directives for business organizers, systems, and services necessary for a megapolis is carried out based on calculated and economically sound principles. In many ways, the work of the e-government is guided by similar principles. The main principles are still the commitment to sustainable development34 and maintaining the quality of life of the population.27,35 High rates of urbanization have caused large-scale shifts in the entire structure of relationships (relationships between business entities operating in a given territory, administration, and the population as a user of public resources). It is necessary for management structures36 or administration bodies to exclude decision-making37 based on heuristic methods. The authors consider the success of smart city development due to the community’s acceptance of new technologies.38 COVID-19 seems to be a driver for the digital transformation of ecosystems worldwide.39 The dynamics of the mutual influence of different types of activity have intensified. Over the past decade, the world has come to increasingly rely on scientific and technological achievements. This inevitably entails negative consequences, which, in conditions with a high concentration of population and industry, inevitably create problems of both a social and economic orientation. The nature of these externalities is not determined solely by their impact on the environment. The quality of life, in general, is also negatively affected. The desire of the population to move to megapolises is determined by the high-quality standards of the living environment. If radical measures are not taken to regulate the entire infrastructure, we will see the opposite effect. The functioning of numerous social institutions, public utilities, the service sector, and the industrial sector should be coordinated within smart city digital platforms.
The development of algorithms for making intelligent decisions is only possible today by combining digital data flows, big data technologies, and information communications into a single system. Decision criteria can be multifaceted. Science-based accounting of the balance between profit affecting the welfare and minimizing the negative impact of industrial urbanization is needed. The solution to socio-territorial problems depends on the quality of management decision-making algorithms. These should be based on mathematical models that are close to reality and methods for finding optimal solutions.
The authors propose a complex approach to consider the socially-oriented combination of ICT (information and communication technology) tools for the rational use of resources to improve life quality indicators. The authors attempt to develop a smart city concept considering the public sector concept model (PSCM). The authors’ recommendations are aimed at organizations that provide services and manage data in cities. The proposed approach addresses the interoperability of systems and data-sharing so that information from different sources can be normalized, classified, shared, and understood, with data derivation linked back to previous layers and the impact of decisions observable in operational data. The stated principles of formalization are the basis for developing a mathematical model. The use of the decision algorithm serves as a rationale for making several management decisions. At present, the concentration of business and cultural activity on a limited territorial scale dominates. This gives rise to the need to determine the feasibility of internalizing the numerous effects of business or governmental activities. The presented technique makes it possible to formalize these according to the externalities principle and apply a multidimensional balance calculation to minimize the potential damage caused. It is necessary to carry out the analysis on a verified, scientifically based calculation. The result of mathematical modeling will be the optimization of the amount of expenses that various members of the business community must bear. It should be noted that today, in the decision-making process, dynamic analyses of the situation in the economy using digital twins are not carried out, and methods for finding optimal solutions are not applied. All of these shortcomings occur for many reasons. These include the imperfection of methods and the complexity of taking into account many factors. We would also point to the lack of correct theoretical models and digital twins of processes in megacities based on accounting for economic indicators.
