Figure 13
The horizontal axis is labeled “Relevance degree (Centrality)”, and the vertical axis is labeled “Development degree (Density)”. Dashed lines divide the plot into four quadrants labeled “Niche Themes” at the upper left, “Motor Themes” at the upper right, “Emerging or Declining Themes” at the lower left, and “Basic Themes” at the lower right. In the upper left quadrant, a bubble labeled “sustainable development”, “corporate social responsibility”, and “sustainable development goal” appears above the horizontal dashed line and left of the vertical dashed line. In the upper right quadrant, a bubble labeled “financial market”, “united states”, and “covid-19” is positioned above the horizontal dashed line and right of the vertical dashed line. In the lower right quadrant, a large bubble labeled “sustainability”, “banking”, and “islamism” appears just above the horizontal dashed line and right of the vertical dashed line. In the lower left quadrant, smaller bubbles including “developing world” and “strategic approach” appear below the horizontal dashed line and left of the vertical dashed line, while “financial provision” is placed further down in the same quadrant. In the lower right quadrant, near the lower center-right area, “empirical analysis” and “knowledge” are positioned slightly below the horizontal dashed line and right of the vertical dashed line. The bubble for “sustainability”, “banking”, and “islamism” is the largest, the cluster around “sustainable development” is medium-sized, and the remaining themes are smaller in size.Thematic analysis.
