Bibliometric analysis of stock market performance throughout the COVID-19 outbreak

In this study the author examines the effect of the speed of population aging on the financial markets in 11 OECD (The Organisation for Economic Co-operation and Development) countries after controlling the proportion of labor population, the growth rate of real GDP (Gross Domestic Product), the rate of increasing productivity, inflation rate, and the rate of increasing scale of pension market. The author finds that the performance of stock market is affected by complex factors including increasing of average life expectancy, the growth rate of real GDP, the rate of increasing productivity, the inflation rate, the earning rate of stock market and the rate of increasing scale of pension market. Especially, the proportion of economically active people is the most significant factor to explain the stock market performance. Considering the decreasing proportion of economically active people in aging societies, the decrease of productivity and eventually the decrease of earnings from financial markets would be expected.

Generation Z makes up the largest proportion of the world’s population and owns active spending power. Born in the internet information age, they have diverse values and consumer behaviors compared to other cohorts of generations. While there has been a significant increase in research on the purchasing behavior of Generation Z in recent years, there are particularly few bibliometric studies in this field. This study aims to sort out the current research status on the purchasing behavior of Generation Z, identify the evolution of purchasing behavior research of Generation Z, determine key research hotspots, and explore future research directions and priority suggestions by analyzing the current literature. The bibliometric analysis is based on the citation information of 638 literature items about Generation Z purchasing behavior in the Scopus database. The results sort out the knowledge structure of the purchasing behavior domain of Generation Z and draw a visual map of the network. Four popular research themes are identified based on keyword co-occurrence analysis, namely the influencing factors of Generation Z consumption behavior, the comparative study with other generations of consumers, the analysis from the perspective of human demography, and the study of sustainable consumption behavior. Studies on Generation Z consumers’ spending habits from 2001 to 2022 may be divided into three stages related to the growth process of Generation Z. Future research should focus on the influence of social media on the purchasing behavior of Generation Z and the sustainability of their consumption patterns.

Dynamic capabilities theory has become one of the most widely accepted theories of business strategy. The study aims to determine the degree of development of the dynamic capabilities theory. A meta-analysis was carried out through a bibliometric analysis and a systematic literature review. Documents published in Scopus and Web of Science between 1997–2023 were analyzed using VOSviewer software. 49 documents met the analysis requirements, with a maximum of 11 published in 2022. Keyword co-occurrences were also analyzed. 222 were found, and 26 were selected with at least two co-occurrences. The documents were grouped into six clusters by these keywords and analyzed to determine the degree of development of the theory. The results have shown popularity among researchers in different science branches, indicating a high degree of development. However, the study noted a lack of theoretical consistency in elaborating constructs for measuring variables in empirical investigations. As a result, this leads to a lack of consistency and generalization of the results. Hence, the theory is not considered fully developed in terms of lack of internal coherence, falsifiability, and predictability. Tools for the empirical measurement of variables need to be theoretically and empirically validated to ensure their application in different contexts. The confrontation of results from validated measurement tools in diverse environments will contribute to developing dynamic capabilities theory.
