Based on the panel data of the Industry-University-Research institution Collaboration (IURC) in Guangdong Province from 2005 to 2009, the innovation efficiency of 260 companies is empirically evaluated using the stochastic frontier model, and the key factors influencing IURC efficiency are researched from the system perspective. The results show that the cooperative innovation efficiency in the sample period is still low but is steadily increasing; the influence effect and path are diverse among key-factors in the system. Entrepreneurship, external technology dependency, and government subsidy have a significantly positive effect on IURC efficiency, among them government subsidy has a long-acting effect on it; the cooperation pattern shows a significant negative impact on IURC efficiency, while export orientation has a higher non-efficiency impact degree. The impact of industry differences on IURC efficiency is unable to pass the significance test. Finally, the limitations and future directions are discussed according to the related theory and practice.
