This research demonstrates that the mother factory system has been getting increasingly complex and dynamic changes have been taking place through the influence of global factory networks on technological knowledge transfer. Network and statistical analyses are completed using data from Japanese factories (2012 to 2015). The result shows that when a firm has a strategy of creating a global network by a self-sustaining factory with the capability of product development and providing global offerings, the number of network creeks of the factory promotes the technological knowledge transfer. Nonetheless, the strategy of the top grandmother factory in Japan has no influence on technological knowledge transfer and indicates the enhancement of the control of the mother factory area in the global network.
