Abstract: For the productization and project-based makers of complex hardware, this article researched the process control mechanism and collaborative extent of mass entrepreneurship space and hardware maker combined the exploratory case study method and Stackelberg game analysis.The main conclusions are as follows: (1) Exploratory case found there is a refined management route in the process of collaborative hardware entrepreneurship; (2) We draw from the Stackelberg game of collaborative entrepreneurship is giving play to the overall effect and necessary for mass entrepreneurship space and hardware makers. It can effectively increase product definition precision of hardware makers. It also can solve hardware makers' sore spots of supply chain and channel integration; (3) Collaborative extent is the inverse of hardware makers' key resource investment and product definition ability. The results show that the collaborative entire effect can control a refined hardware entrepreneurship process when mass entrepreneurship space grasp a reasonable degree of collaborative participation. It could be a new entrepreneurial paradigm of resource sharing and coordinated hardware industrial chain.
