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