Research on the Development of Patents in Key Fields of the Automotive Industry in Huangpu District

Against the backdrop of the global automotive industry's transformation towards "electrification, intelligence, connectivity, and sharing" (the "New Four Modernizations"), patents have become a core indicator for measuring the technological innovation capability of the industry. This study takes the automotive industry in Huangpu District as the research object. It first sorts out the macro-development trend of patents in China's automotive "New Four Modernizations" field, then focuses on three key areas of Huangpu District: power batteries, charging systems, and intelligent perception. Through the analysis of patent quantity, type, technological layout, and enterprise entities, the study reveals the advantages and shortcomings of Huangpu District's patent development. The research finds that Huangpu District has formed characteristics in battery swapping technology and basic research and development of intelligent perception, but there are problems such as insufficient layout of segmented technologies in power batteries and unbalanced structure of charging technologies. Finally, combined with industry trends, strategies such as targeted R&D, technological collaboration, and forward-looking layout are proposed to provide reference for Huangpu District's automotive industry to enhance its patent competitiveness.
