Standardization is an important technical means to promote the development of strategic emerging industries. Data source based on technical standard information of new energy vehicle in China from 2001 to 2019. From two dimensions, network construction and innovation value chain, content analysis of 148 national technical standards and industry technical standards for China"s new energy vehicle industry. The results show that the network under the technology standardization of new energy vehicle industry has evolved from simple to complex, the scale of the network continues to expand, network distance and cohesion index show fluctuating state; There is a clear “core-edge” structure layering between the nodes of the new energy vehicle technology standardization network, so it is necessary to promote the diffusion linkage from the core area to the edge area and promote the core node to drive the edge area node; the new energy vehicle technology standards are based on the core parts of the power battery in the product development stage, and then develops into the market promotion stage to form a comprehensive system of “complete vehicle-parts”, this is a gradual process; There are differences among the innovation subjects in the innovation value chain, in the link of R D, scientific research institutes and universities are the main innovators, in the link of product introduction, enterprises and universities are the main innovators, enterprises play an important role in the link of market promotion of new energy vehicles.
