笹井均先生退職記念号In this paper six measurement scales are developed for practices, process, strategic guide and capabilities of new product development as potential determinants of its performance, based on the survey data from Italian and Japanese machinery, electrical & electronics companies. Eight indicators are proposed to measure new product development performance. A multiple regression model with a country dummy variable is employed to estimate the differential determinants of performance between Italian and Japanese companies. Significant differences are found in the impacts of new product development capabilities on attainment of profit goals and product quality capability, suppliers' linkage on revenue percentage of new products, and strategic guide on time-to-market reduction. This analysis demonstrates the overwhelming importance of technology and marketing capabilities concerning new product development. The final analysis evaluates the level of improvement in explanatory power by dividing the pooled sample into two sub-samples, that is Italian and Japanese samples, and enabling regression coefficients to take different values for each sample There are no evidences of significant improvement.
