The Consequences of Economy Servitization for Ensuring Energy Sustainability-The Case of Developed and Developing Countries

This study presents an analysis of the relationship between the servitization process and energy sustainability in the years 2015-2020. The research refers to 164 selected countries, also divided into two regimes: developed and developing. The transformation of the manufacturing process, and as a result, the economy's structure, towards servitization, is observed in most countries worldwide. The positive influence of the servitization of production by individual manufacturers on sustainability is widely known. In this research, this relationship is considered on a macroeconomic scale, which is one of the novelties of the study. Particularly, sustainability in the energy sector, indicated as an achievement of the 7th goal of Sustainable Development, is discussed. Energy sustainability is evaluated using a synthetic measure by Perkal. This part of the research shows the problem of the low level of energy sustainability in developing countries (particularly in Africa) compared with developed ones. Moreover, spatio-temporal sensitivity models are estimated and verified. The sensitivity parameter in these models shows the impact of the progress in the servitization process on energy sustainability. The models have been enriched with the effects of spatial dependence between countries, taking into account two types of proximity matrices based on (1) the common border criterion and (2) the similarity of the development levels measured by the Human Development Index. Additionally, the differences in sensitivity between developed and developing countries are considered. The results of the study show that in both cases, the economic servitization positively influences energy sustainability, but the strength of the relationship is stronger in the group of developed countries. This can be, for example, the result of the individual characteristics of the given countries, where African countries mainly benefit from agricultural development. Only after reaching a certain level of economic growth will they be able to obtain sustainability faster through economic servitization.
