The Empirical Study on Relationship between Design-Manufacturing Integration and Manufacturing Performance of Chinese manufacturing Enterprises

Nowadays, researchers' study on DMI more focus on the influence of DMI to new products or new products development, Few focus on the influence to the manufacturing performance in manufacturing enterprises. Especially it lacks empirical research on how DMI's various activities influence manufacturing performance and how interact on each other between them. Based on the theoretical analysis on DMI, this paper analyzes the correlations between horizontal organizational integration, design integration, technological integration and the relation between them and manufacturing performance, provides the hypothesis, and carries out the empirical research on 150 enterprises in china in 2009's International Manufacturing Strategy Survey, it turned out that horizontal organizational integration, design integration between design and manufacturing departments have positive promoting effect on technological integration. Horizontal organizational integration, design integration and technological integration have positive promoting effect on manufacturing performance. Technological integration plays mediating effect between horizontal organizational integration and manufacturing performance. Technological integration plays mediating effect between design integration and manufacturing performance.
