In this study, the various influencing factors presented in the prior studies in Korea relating to technology commercialization were classified and grouped into 8 upper group factors and 16 subgroup factors based on their theoretical background. Meta-Analysis was then conducted to figure out the average effects size of overall influencing factors and to identify the key success factors of technology commercialization. In addition, moderator effects were analyzed based on paper type, data type, and sample size. The results showed .3576 of correlation coefficient (ESr) as the summary effect size from 72 studies with 18,370 samples and six (6) factors were derived as the key success factors of technology commercialization: Marketing Capability, Strategic Planning, Manufacturing Capability, Internal Cooperation, External Cooperation, and Learning Capability. Moderator effects were found with data type and sample size but no significant results were obtained with the paper type.
