Figure 4
The two-axis thematic map is divided into four quadrants by a vertical dashed line and a horizontal dashed line intersecting at the center. The vertical axis is labeled “Development degree (Density)” and the horizontal axis is labeled “Relevance degree (Centrality)”. The top-left quadrant is labeled “Niche Themes”, the top-right quadrant is labeled “Motor Themes”, the bottom-left quadrant is labeled “Emerging or Declining Themes”, and the bottom-right quadrant is labeled “Basic Themes”. In the top-left quadrant, a green circular node labeled “conceptual model” is positioned near the upper center-left. Below it, a smaller gray node labeled “Circular purchasing” appears above the horizontal midline. In the top-right quadrant, a light blue node labeled “organizational learning” is positioned above the horizontal midline and to the right of the vertical midline. In the bottom-left quadrant, two nodes are present. A yellow node labeled “employee engagement” appears slightly below the horizontal midline and left of center. Further down, a pink node labeled “dynamic capability” is positioned near the lower-left area. In the bottom-right quadrant, several nodes are clustered. A small light blue node labeled “s m e s” appears near the lower center-right. Slightly above it, a green node labeled “sustainability” is positioned. To the right of “sustainability”, a larger orange node labeled “innovation” is placed near the lower-right area. Above “innovation”, a large purple node labeled “entrepreneurship” is located near the mid-right. Slightly above and left of “entrepreneurship”, a gray node labeled “middle managers” appears. To the left of “middle managers”, a pink node labeled “bio-economy” is positioned.Strategy diagram in the study of corporate entrepreneurship and circular economy
