Figure 3
The horizontal axis is labeled “Relevance degree (Centrality)” and the vertical axis is labeled “Development degree (Density).” A dashed horizontal line and a dashed vertical line divide the plot into four quadrants labeled as follows: top-left is “Niche Themes,” top-right is “Motor Themes,” bottom-left is “Emerging or Declining Themes,” and bottom-right is “Basic Themes.” In the top-left quadrant labeled “Niche Themes,” the keywords “coordination,” “contracts,” and “demand” appear together near the top, while “subsidies,” “impacts,” and “progress” are positioned lower and toward the center. On the dividing line between “Motor Themes” and “Basic Themes” lie the keywords “firm performance,” “competitive advantage,” and “absorptive-capacity” grouped together. On the dividing line between “Emerging or Declining Themes” and “Basic Themes” lie the keywords “economic-growth,” “c o 2 emissions,” and “energy-consumption.” In the bottom-right quadrant labeled “Basic Themes,” the keywords “performance,” “impact,” and “management” appear together within a purple-shaded cluster. Slightly above them and shaded in red, the keywords “china,” “growth,” and “innovation” form another cluster. A small cube icon resembling a logo is placed near the lower-right corner.Thematic map.
