The article identifies at least three structural factors simultaneously narrowing the space for traditional product categories. First, global supply chain reorganization: purchasing decisions are becoming more dispersed, undermining the old model of stable orders based on long-term relationships. Second, China exporting excess capacity at low prices: the Ministry of Finance's H1 2025 report directly names Chinese overcapacity being sold to overseas markets as a cause of year-on-year declines in chemicals and plastics/rubber, creating downward price pressure. Third, resources and attention concentrating on AI and ICT applications, making it harder for traditional categories to attract new customers, capital, and demand. These three forces are not cyclical economic fluctuations that will disappear with economic recovery—they continuously erode traditional manufacturing's share of global markets.
