Abstract: during the process of the developing country's manufacturing industry from low-end to high-end migration, a problem to be solved is how to achieve technological catch-up. To this end, the article takes the typical enterprise of mature industry in our country as the sample, using the grounded theory to study the technology catching up process in the developing countries, trying to make the research conclusion that has the potential social value. Based on the technological catch-up inertia conduction path model, the study found that: (1) different from the most studies results, inertia factors is not hindering factors in specific conditions, but to promote enterprise to realize the technology catch-up as the original driving factors; (2) in the different stages of technological catch-up, dominated inertia exhibits different characteristics and through the interaction between different inertia to drive technology catch-up process completed; (3) the role of achievement inertial is through the whole process of technology catch –up.
