The recent spotlight on BYD's "Di Chain" system has ignited widespread debate. Wei Jianjun, Chairman of Great Wall Motors, subtly raised concerns about underlying risks in the automotive sector, drawing public attention to BYD's financial health, particularly its high debt-to-asset ratio of 70% and total liabilities amounting to 584.66 billion yuan. In response, BYD emphasized that its debt ratio and payment terms fall within industry norms. Subsequently, several automakers committed to paying their suppliers within 60 days. An official from the Ministry of Industry and Information Technology echoed this sentiment, emphasizing the importance of automakers reasonably managing their payment cycles to foster a healthy and sustainable automotive industry. As an innovative financial tool within BYD's supply chain, Di Chain facilitates settlement through electronic debt instruments, intended to alleviate funding issues. Nonetheless, it has also sparked discussions regarding prolonged payment cycles and the financial strain this places on suppliers.
