How does China's deep and rapid supply chain ecosystem provide a structural advantage for hardware and software innovation?

Over the past two decades, China has developed an unmatched ecosystem for automotive components, electronics, sensors, and manufacturing. A German automotive executive recently described China as a wonderland for supply chains because any new prototype idea can be sourced, iterated, and delivered within days. Instead of waiting weeks for international communications, engineers can coordinate suppliers via instant messaging or take a high-speed flight between Beijing and Shenzhen within three hours, treating the entire country as an integrated manufacturing village.
