In this research, we display the trajectories of Vietnam’s environmental pressure throughout the years during 2008–2018 and identify the underlying socioeconomic driving factors through input-output and forward-backward linkage analysis. Decoupling index (DI) and input-output analysis (IOA) indicated that mining, the extraction, and use of fossil fuels, as well as energy generation for daily life and manufacturing industries, are the primary contributors to rising environmental pressures (DI; forward and backward linkage values > 1). Vietnam’s decoupling performance has four distinct phases. Mineral and fossil fuel depletion; climate change in the short-term and long-term, and water stress indexes (the ratio of total annual freshwater withdrawal to hydrological availability) were high with 456.91%; 55.91%; 54.43%; 41.87%; and 30%, respectively during 2008–2018.

Purpose: The purpose of the article is to present systemic determinants of structural changes in the economy Design/methodology/approach: The article uses critical literature analysis. The theory of structural changes and system theory was reviewed to reveal the impact of the economic system on changes in the economic structure. Findings: Owing to the conducted analysis, the relationship between the system and the economic structure was presented. On the one hand, shaping the structure turned out to be strategically important for the entire system. On the other, the structure may depend on broadly understood conditions resulting from the properties of the system itself or its environment. Hence, for the same purposes, the systems may differ in their structure, which will be chosen to apply to the existing determinant. It can therefore be assumed that the system is an important determinant for structural adjustments in the economy. Originality/value: The literature on the subject, as the main factors of changes in economic structures, primarily reveals: the introduction and diffusion of new technologies and the increase in global trade. The nature of their influence has been extensively described by economists. However, systemic determinants of structural transformations are still hardly documented.

The aim of this article is to investigate the relationship between the cyclical fluctuations in Poland on a regional perspective and the level of specialization of regional economies. To do this, the correlation between the morphology features of regional business cycles and the level of their specialization was made. The morphology features were represented by such parameters: cycle length, phase length, standard deviation ratio, coefficient of variation ratio and average amplitude of upward and downward phases. The evolution of economic structures was measured by the Krugman specialization index. Assessing the GDP cyclical fluctuations in the Polish regions during 1996–2013, it can be concluded that the regions have different sensitivity to economy “shocks,” both positive and negative. The results of the regional specialization measuring are ambiguous. Most of them appear falling specialization, and the others show stable specialization levels. Despite a few exceptions, a correlation between the level of regional specialization and the degree of sensitivity to economic disturbances can be observed. Regions that are less specialized and have more-diversified production structures show greater resistance to economic fluctuations. This is confirmed by the analysis of the morphology of cycles on a regional basis.
