According to the root cloud platform of the Ministry of Industry and Information Technology, the construction machinery operation rate in May this year was 67.15%. Through the "excavator Index", it was found that driven by a series of stable investment measures, the progress of infrastructure construction in many parts of the country has accelerated significantly. Wang Jinxia, an analyst at excavator Index, said that due to the improvement of the epidemic prevention and control situation, including the intensive introduction of investment policies in some countries, the data on the operating rate of construction machinery continued to increase, reflecting the continued recovery of large-scale construction projects and the release of demand.
