Since the beginning of this year, promoting the upgrading and renovation of various types of equipment has become a key part of expanding domestic demand. Related engineering projects have started construction one after another, and investment enthusiasm has increased - multiple high-frequency indicators that intuitively reflect the economic operation situation confirm this trend. According to the latest data obtained by the Big Data Development Department of the National Information Center, the manufacturing investment heat index grew by over 40% in March, with a year-on-year increase of 65.5% in heat related to equipment updates, renovations, and upgrades, far exceeding the overall growth rate of engineering projects, highlighting the huge investment potential brought by equipment "renewal". Recently, the green painted 30000 ton forging press machine "water to oil" project on the forging production line of Southwest Aluminum Forging Plant has been successfully completed and officially resumed production. It is reported that the 30000 ton forging press has provided materials for major projects such as China's Long March series rockets and Shenzhou series spacecraft. With the rapid development of China's aerospace technology, new processes and products have put forward higher requirements for this equipment, and upgrading and renovation have been put on the agenda. "By transforming the 30000 ton forging hydraulic press into a forging hydraulic press, the equipment body and control accuracy have been greatly improved, the forging quality has been significantly enhanced, and the production efficiency will also be greatly improved. This will provide more solid and powerful support and guarantee for Southwest Aluminum's production of advanced aerospace materials such as die forgings and high-temperature alloys." said the relevant person in charge of Southwest Aluminum. For a period of time, various regions have been targeting high-end, intelligent, green, safety and other key directions, promoting large-scale equipment updates in the industrial field. The project investment heat index constructed by the National Information Center based on project bidding data shows that investment heat increased by 0.6% year-on-year in the first quarter of this year, with a year-on-year increase of 5.8% in March, showing an accelerating growth trend. Among them, the growth of investment in the manufacturing industry is outstanding, with a year-on-year increase of 13.3% in the manufacturing investment heat index from January to February, and a rapid increase to 40.6% in March, far higher than the overall growth rate of bid winning amounts in the country. "Especially in terms of investment in equipment updates and renovations, the performance was impressive. In March, the heat related to equipment updates, renovations, and upgrades in the manufacturing industry increased by 65.5% year-on-year, surpassing the overall investment heat growth rate of the manufacturing industry by nearly 25 percentage points." said Yang Daoling, Director and Researcher of the Big Data Analysis Department of the National Information Center's Big Data Development Department. "With the continuous recovery of the economy, the demand for technological innovation investment continues to be released, providing important support for manufacturing investment. The recently launched equipment renewal policy is conducive to further promoting the increase of technological innovation investment demand," said Luo Huanjie, a researcher at the Chief Industrial Research Institute of Guangkai. After the implementation of the Action Plan for Promoting Large scale Equipment Renewal and Consumer Goods Exchange, issued by the State Council, the equipment renewal plan for the industrial sector has been officially released recently. It proposes four major actions, including the implementation of advanced equipment renewal action, digital transformation action, green equipment promotion action, and intrinsic safety level improvement action, including aviation, photovoltaics, power batteries, additive manufacturing equipment, industrial robots and other industry sectors. Zhao Chenxin, Deputy Director of the National Development and Reform Commission, stated that according to relevant institutions, the net value of the total stock assets of equipment in society is approximately 39.3 trillion yuan, of which the stock assets of industrial equipment are approximately 28 trillion yuan.
