Since 2021, the export of second-hand excavators from China has grown rapidly, reaching 120,000 units in 2024, surpassing the domestic demand and export volume of new excavators for the first time. In May 2025, the export volume of second-hand excavators increased by 52% year-on-year [6]. Compared with manufacturing new products, the remanufacturing industry can save 60% of energy, 70% of materials, and reduce emissions by 80%. At the beginning of 2024 and 2025, the state policy supported equipment renewal and the upgrading of the remanufacturing industry, promoting the trading of second-hand goods. The number of construction machinery in China has exceeded 10 million units, and there is a large demand for the circulation of second-hand equipment. The remanufacturing industry has room for development.
