Abstract
Based on the introduction of complex social network theory and methods, this study reveals enterprises' patent layouts to help Chinese enterprises distinguish the core competitors. This study uses the social network analysis method and the system cluster analysis method to systematically analyze the macro technology development trend and competitors' micro technology innovation points. Based on the structure of enterprise resource investment, a two-dimensional matrix with the keyword “similarity-technological competition intensity” was constructed to accurately identify BYD's core technological competitors. In China, BYD company should regard GX company and ND company as core technology competitors, pay attention to the technology development direction and patent layout of YW company and HD company, and pay attention to the patent dynamics of GLM company and YQ company in specific technological innovation points.
Highlights
In recent years, China has been vigorously developing new energy, materials, and technology-based strategic emerging industries
Analysis of the Scope of Technological Competition in the Industry. e International Patent Classification (IPC) promulgated by the World Intellectual Property Organization (WIPO) is a standard international classification method for patent technology. e IPC number represents the coverage of patent technology and the direction of technology development of enterprises [16]. e greater the number of repetitions of IPC numbers between different firms, the greater the technological competition between them, indicating more technically identical or similar areas
BYD should keep an eye on the patent technology development direction of GX and ND, especially the common trend between core technology and auxiliary technology, to be alert to competitors’ patent layout of Li-ion battery technology
Summary
China has been vigorously developing new energy, materials, and technology-based strategic emerging industries. As one of the new energy industries, the lithium battery industry steps into the fast development track. Affected by the growth of the new energy vehicle market and national policies, domestic demand for lithium-ion production equipment exceeded 17 billion yuan in 2017. China has become the world’s leading production base for lithiumion power batteries for vehicles. As the lithium battery industry enters a rapid growth period, the number of enterprises in related fields is rapidly rising. E competition between enterprises in the industry is becoming increasingly fierce; quickly and efficiently identifying the core competitors has become the key to gaining a competitive advantage in the market. There are different kinds of methods for identifying core competitors of enterprises
