Modern cities face a number of challenges, among which growing urbanization over the years, environmental pollution, climate change or the problem of efficient resource management play a key role. In this context, the smart city concept, based on modern technologies and innovative solutions, is becoming a leading element of development strategies. Polish voivodeship cities, as regional centres, are increasingly implementing smart city solutions to improve the quality of life of residents, increase the efficiency of government operations and promote sustainable development. The purpose of this article is to determine the extent to which the smart city idea is incorporated into the development strategies of Polish voivodeship cities, and to identify the areas in which these solutions are of greatest importance. The analysis covers six dimensions of the smart city: economy, mobility, environment, people, quality of life and governance. The study consisted of two stages: a literature analysis and a review of cities' strategic documents using thematic modelling tools.

The pandemic disrupted traditional supply chains and world trade deeper than other crises in the recent past. In a complex business environment, companies need to rethink and redesign their supply chains for the resilience and flexibility they need. Therefore, the purpose of this article is to identify trends and logistic solutions that should be considered in order to skillfully navigate in the new reality. Based on the literature review and the experiences of enterprises, the role and importance of resilience and risk management in ensuring the efficiency and transparency of supply chains will be indicated.

The article carries out an argument justifying the stabilizing role of logistics in achieving well-being in a period of surprising and unexpected changes. The arguments presented are based on time-varying relations between logistics and well-being as well as on the reactivity of logistics to changes in the environment.

Managers of the public sector are increasingly looking for new opportunities to offer residents a
larger package of benefits that contribute to improving the quality of life. One of them is public
logistics, which has the potential to integrate and coordinate activities in the implementation of
public tasks. However, public sector concerns regarding private performance of benefits are still
relatively high. This is due not only to the lack of confidence in the external performance of tasks, but

also to the lack of transparency in the relationship between the public and private sectors. This is
justified by agency theory. A way to improve relations and optimize the offer in the city can be
blockchain technology, which is a revolutionary and ground-breaking technology that promises to
change the way interactions between city stakeholders. It offers new alternatives not only to shape
city-society relations, increase public sector transparency, but also to facilitate the transmission of
confidential data without compromising privacy and security. In the article I will attempt to assess
the possibilities of using blockchain technology in the implementation of public tasks and in everyday
contacts of the public sector with stakeholders. I tried to show the possibilities of blockchain
technology in shaping the relationship between the public sector and society and entities from the
non-public sector involved in the implementation of public services.
