Cement network data: statistics of cement output of all provinces and cities in China from January to March 2026

The statistical data of cement output in all parts of the country from January to March 2026 show that the cumulative output of cement in the country has a certain scale. From the year-on-year data, the situation varies from place to place. The output in most regions showed a trend of year-on-year decline, among which the decline in Liaoning, Shaanxi, Fujian and other places was more obvious, for example, the year-on-year decline in Liaoning was larger; while the output in Beijing, Guizhou, Hunan and other places increased year-on-year, and the year-on-year increase in Beijing was relatively prominent. The smaller year-on-year change in production was in Zhejiang, which decreased by only 0.03%. The overall output of the whole country decreased by 7.10% year on year.
