This paper investigates the relationship between suppliers' performance and their parts transactions with customers in Japanese automobile industry. We generate a hypothesis focusing on supplier's learning processes, and test it using Japanese auto parts transactions data set during the period 1993-99. Results show that suppliers who prove important to the main customer at the same time maintaining business relationship with numbers of other customers, tend to surpass other suppliers in their performance. In other words, we find how important it is for suppliers to build stable business tie with the main customer and broaden relationship with other various customers.
Content analysis proves to be very useful in inferring the intention among competing firms. Content analysis is the systematic and replicable examination of symbols of communication. Like individuals, firms render messages outside of themselves. Their daily activities are, so to speak, communications process. Therefore researchers are able to apply content analysis to the exploration of firms' behavior. This paper will take up, as one of these cases, new products news releases made by inkjet printer makers. Through the analysis, the product concept trajectory is developed. These depicted trajectories show us the intention of competing firms.
