The structural model shows six oval nodes arranged from left to right with directional arrows connecting them. The left column contains three oval nodes labeled “C x O” at the top, “C o O” in the middle, and “L e O” at the bottom. The middle column contains one oval node labeled “Tech O”. The right column contains two oval nodes labeled “I 4.0-Base” at the top and “I 4.0-Front-end” at the bottom. Percent values appear near the right-side nodes. From “C x O” at the top left, a dashed arrow extends horizontally to “I 4.0-Base” labeled “minus 0.017”. From “C x O”, a solid diagonal arrow slopes downward to “Tech O” labeled “0.260 asterisk”. From “C x O”, a dashed diagonal arrow slopes downward toward “I 4.0-Front-end” labeled “minus 0.114”. From “C o O” in the middle left, a dashed diagonal arrow slopes upward to “I 4.0-Base” labeled “minus 0.2”. From “C o O”, a solid horizontal arrow extends to “Tech O” labeled “0.290 asterisk”. From “C o O”, a dashed diagonal arrow slopes downward to “I 4.0-Front-end” labeled “0.135”. From “L e O” at the bottom left, a solid diagonal arrow slopes upward to “TechO” labeled “0.285 aeterisk”. From “LeO”, a dashed horizontal arrow extends to “I 4.0-Front-end” labeled “minus 0.020”. From “LeO”, a dashed diagonal arrow slopes upward to “I 4.0-Base” labeled “0.194 asterisk”. From the middle node “Tech O”, a solid arrow slopes upward to “I 4.0-Base” labeled “0.344 asterisk”. From “TechO”, a solid arrow slopes downward to “I 4.0-Front-end” labeled “0.209”. Next to the right column nodes, text shows model fit values. Near “I 4.0-Base” the text reads “R superscript 2 equals 49.8 percent”. Near “Tech O” the text reads “R superscript 2 equals 53.6 percent”. Near “I4.0-Front-end” the text reads “R superscript 2 equals 5.5 percent”.Structural model testing results. Notes: *p < 0.05, The dotted arrow line indicates that the relationship was not statistically significant
