China’s high-tech manufacturing profits jump 52% in Jan-Sept

The outsized profit growth in high-tech manufacturing, and the specific strength in fiber-optic and cable manufacturing tied to computing-power and data-center buildout, points to AI and cloud infrastructure spending as a real earnings driver inside China's industrial economy, not just a narrative. The widening gap between high-tech and overall industrial profits also suggests a structural tilt in profitability that matters for how China's manufacturing base is valued. Whether the data-center-led demand behind fiber and cable margins persists, and whether the high-tech share of total industrial profits keeps climbing, is the open question.
