Figure 5
The illustration is arranged as a two-by-two grid of line charts, each sharing the same horizontal axis labeled sequentially with the letters “A, B, C, D, E, F, G, H, J, K, L, M, N, O, P, Q, R”. In the top-left panel titled “Knowledge depth”, a single curve with circular markers shows the values 14 at A, 4 at B, 3 at C, 5 at D, 7 at E, 13 at F, 11 at G, 16 at H, 1 at J, 15 at K, 6 at L, 2 at M, 10 at N, 16 at O, 8 at P, 12 at Q, and 9 at R. In the top-right panel titled “Technology demonstration”, one curve displays 14 at A, 15 at B, 12 at C, 13 at D, 10 at E, 6 at F, 4 at G, 3 at H, 5 at J, 16 at K, 2 at L, 1 at M, 11 at N, 17 at O, 7 at P, 8 at Q, and 9 at R. In the bottom-left panel titled “Embedding depth”, the curve shows 15 at A, 12 at B, 9 at C, 14 at D, 10 at E, 8 at F, 4 at G, 16 at H, 3 at J, 6 at K, 2 at L, 5 at M, 11 at N, 16 at O, 13 at P, 1 at Q, and 7 at R. In the bottom-right panel titled “Knowledge flow”, the curve presents 13 at A, 16 at B, 8 at C, 14 at D, 11 at E, 4 at F, 5 at G, 15 at H, 2 at J, 10 at K, 1 at L, 7 at M, 12 at N, 17 at O, 9 at P, 3 at Q, and 6 at R. Each panel contains a single continuous line with point markers and printed numeric labels to support comparison across the four metrics.Ranking of industrial digitalization participation breadth by secondary indicators
