Study On Evoluation Of Catching-up Enterprise's Technology Chain Based On Patentometrics

Along with the global economy integration, the evolution regularity of technical capability and technology chain in the catching-up enterprises is becoming a new research hotspot.Qualitative analysis was used to make research on the issue of the technology catching-up by most scholors. Howerver, compared with qualitative analysis, patent analysis is more objective. Patent data is a panel data integrated by cross-sectional and time-series data which has higher accuracy and reliability.This paper objectively verified theevolution process of technology chain on the basis of the automobile industry from the angle of patent. This research work is as follows.This paper gave the general mode of the technology chain's construction in catching-up enterprises. Enterprises in the developing countries should set up their technology chain from the assembly technology to the dominant design (new technology principle), which is ordinal and advanced, the technological learning of the product architecture knowledge, the technological learning of the component knowledge and the independent innovation based on new technology principle.This paper selected the Korean hyundai motor company and Chinese chery automobile company as the research objects.First, the technology life cycle of core component was predicted by using Logistic model.Then, a division of the technology chain was presented and it was found that the evolution of the technology chain tended to speed up with a breakthrough in core technology. Finally, this paper measured the cooperation condition by joint patent applications, patent collaborative rate, collaborative intensity and inventors' productivity and found that technical cooperation between inventors help to improve the patent output of enterprises.
