There are several problems with the quantitative analysis of organizational network. One of them is the calculation of centrality in a network. Linton C. Freeman suggested a way to measure centrality of a network from the viewpoint of degree, betweenness and closeness. I call it Freeman Model and I found if you want to use it to analyze the relationship among firms, you will need to modify it because Freeman Model didn't take any considerations to the weight of the edge in a network. So I suggest a new idea of centrality measurement with the weight and use it to analyze the relationship among firms in Japanese Automobile Industry. Through the result of my analysis, we can find that the position of a node in a network depend on its degree of centrality, and its degree of importance. At the same time, I clarified the high relationships between degree of centrality and its sales, and its ordinary profit. Degree of centrality can be an important index when you draw up the managerial strategy of your organization.
