Compared with the 2019 level, profits of major industrial firms rose by 45.5 percent in H1. The expansion put the average H1 growth for 2020 and 2021 at 20.6 percent, NBS data showed.

Boosted by an expansion in COVID-19 vaccine and testing reagent production capacity, profits of the pharmaceutical manufacturing sector jumped 88.8 percent year-on-year, accelerating from the pace in the first quarter.

The rebound in the industrial sector was in line with China's overall economic recovery. In the first half, China's GDP expanded 12.7 percent year-on-year, with major indicators pointing to resilience in growth.

Noting that industrial firms still face challenges, such as high costs rising from commodity price hikes and weak links in industrial chains, Zhu said the country should make sustained efforts to keep market prices stable and tackle the difficulties of companies.
