Figure 1
The diagram presents a conceptual model flowing from left to right. On the far left, there are two rectangular boxes. The upper box contains the text “Control variables: organizational size, software procurement, frequent supplier changes, short-term relationships.” The lower box contains “Strategic P S M integration.” From the “Strategic P S M integration” box, three rightward arrows extend toward three ovals arranged vertically in the middle of the diagram. These ovals are labeled “Relational capital,” “Cognitive capital,” and “Structural capital.” Each of these arrows is labeled respectively with “positive H 1,” “positive H 2,” and “positive H 3.” From the middle section, additional arrows extend to the right toward three ovals representing types of values. The top oval is labeled “Operational value,” the middle oval is labeled “Innovative value,” and the bottom oval is labeled “Environmental value.” Each oval on the left connects to multiple ovals on the right through arrows labeled with specific hypotheses. The oval labeled “Relational capital” connects to “Operational value” with an arrow labeled “positive H 4 a,” to “Innovative value” with an arrow labeled “positive H 4 b,” and to “Environmental value” with an arrow labeled “positive H 4 c.” The oval labeled “Cognitive capital” connects to “Operational value” with an arrow labeled “positive H 5 a,” to “Innovative value” with “positive H 5 b,” and to “Environmental value” with “positive H 5 c.” Similarly, the oval labeled “Structural capital” connects to “Operational value” with “positive H 6 a,” to “Innovative value” with “positive H 6 b,” and to “Environmental value” with “positive H 6 c.”Research model and hypotheses.
