Complex Network Analysis of China National Standards for New Energy Vehicles

Abstract

Standards are technical measures to regulate and promote sustainability. China National Standards for new energy vehicles (NEV) are developing at an increasing rate. We explored the functions and citation network the China national standards from a complex-network perspective. Different types of standards were clustered and citation relationships were identified based on standards’ document analyses. In this paper, the evolution of standard nodes and citation links are presented, and implications for future standardization work are proposed. In total, 114 existing standards were identified through desktop research and network analysis by using the Gephi ForceAtlas2 algorithm. This study can be helpful for future standardization in areas such as autonomous driving and carbon-related standards based on citation-network analysis.
