The auto parts sector in Jimo District is accelerating its transformation and upgrading, making the leap from conventional build-to-print manufacturing to joint vehicle R&D with automakers and further strengthening the resilience of its 100-billion-yuan-level automotive industry cluster. Local companies are moving upstream into the early stages of vehicle R&D. By having engineers work on site to tackle technical challenges together, they optimize manufacturing processes, dimensions and materials before a model enters mass production, thereby forging stronger and more enduring technical partnerships. They are also refining their business portfolios. By supplying multiple customers and producing a diverse range of products, they have developed flexible manufacturing capabilities that help cushion them against market volatility. Meanwhile, they are making forward-looking moves into smart and high-end segments, securing early positions in emerging fields such as smart electronic rearview mirrors. These efforts have increased product value severalfold and helped them win projects with global automakers. Today, Jimo's more than 400 auto parts companies and leading automakers reinforce one another's growth. Together, they have created a development model built on local sourcing, linkages within and beyond the district, and automakers and suppliers expanding overseas in tandem, driving the regional automotive industry chain toward higher-end, smarter and more globally oriented development.
