The study aims to provide a series of information that will contribute to the understanding of the concept of healthcare marketing and other associated concepts from the perspective of how research in the field has evolved. We aim to quantify the scientific interest in the field of healthcare marketing and to extract aspects that will contribute to a better understanding of the trends that characterize the specific vision of this topic. The research involves a bibliometric analysis, and the conduct of the study is based on the investigation of the academic literature from the Scopus and PubMed databases based on the PRISMA methodology. The study investigates 1077 papers published between 2000 and 2022. According to our study, the most productive countries in the field of healthcare marketing academic publications are the United States, the United Kingdom, and India. As research themes, the study revealed that customer/patient satisfaction, medical tourism, social marketing, and hospital-related marketing topics are highlighted based on cluster analysis of authors keywords. We also discuss the significant lack of research to clarify the use of the concepts such as patient/client/customer in healthcare marketing and to understand the role of prevention services as essential in sustainable healthcare.

Green taxes are taxes collected to protect the environment by controlling the negative effects of certain activities and products on the environment. They are also an instrument of environmental policy and can therefore contribute to several sustainable development goals. According to the studies carried out, the green economy aims to ensure sustainable development. The main objective of this paper is to identify the existing relationships between green taxes and sustainable economic development through a dynamic panel analysis. A dynamic panel analysis was therefore carried out on the existing links between environmental taxes and charges at the European level and the indicators of the circular economy. The results of the two dynamic regressions for the two dependent variables, namely total green taxes and energy taxes, show a positive and significant correlation with the variation of GDP and with primary energy consumption, confirming the hypothesis that environmental taxes and energy taxes are closely linked to these two important indicators of sustainable development. Thus, as GDP changes, the taxes on energy production and the energy products used in both transport and stationary applications increase. As a result of the analysis, we can note that the increase in primary energy consumption and the consumption of raw materials leads to an increase in environmental and energy taxes. Energy taxes are a possible solution to reduce CO₂ emissions in third world countries and may even stimulate climate action. In contrast, we found no significant correlation between green taxes and the following variables: Human Development Index, net greenhouse gas emissions, private investment and gross value added related to circular economy sectors, the consumption of raw materials, waste generated, waste treatment, the supply, transformation, and consumption of renewable energy, public expenditure on environmental protection, and climate-related economic losses.

The owners of the guesthouses in the mountain areas of Bihor County trying to attract guests using more and more social media channels. Their presence on social media channels plays an important role due to the fact that an increasing number of tourists are searching for information by the means of these channels. In this study, we analyzed the presence of the mountain area Bihor County guesthouses on social media channels. We also studied the way in which different social media channels are used by the owners of the guesthouses to attract guests and also the attention paid to each of them.
