Recently, a new batch of major project construction has been launched in various regions, and the progress of ongoing projects has also accelerated. Experts predict that with the follow-up support of special bond funds and bank matching loans, some infrastructure projects will accelerate the formation of physical workload by the end of the year; By the end of the year, 500 billion yuan of additional treasury bond will be put into use, which will also form a strong support for infrastructure investment. It is expected that the growth rate of infrastructure investment will stabilize and slightly increase by the end of the year. Recently, the C6008 first high-speed train slowly started running out of Maoxian Station, and the Qingbaijiang East to Zhenjiangguan section of the Sichuan Qinghai Railway was opened for operation, marking the first high-speed train line in northwest Sichuan. It is understood that the Qingbaijiang East to Zhenjiangguan section of the Chuanqing Railway is a part of China's "eight vertical and eight horizontal" high-speed railway network from Lanzhou, Xining to Guangzhou. The geological conditions along the line are complex and the construction difficulty is high. Each participating unit efficiently promoted the construction of the project, ensuring that the project was completed on schedule. After the opening and operation of this line, the Northwest Sichuan Plateau officially entered the era of high-speed trains. The Sichuan section of the Xicheng Railway, which is a component of the China Lanzhou (West) Guangzhou high-speed railway network with eight vertical and eight horizontal sections, has also pressed the "fast forward" button for project construction. Recently, the No. 1 inclined shaft of the Baozuo Tunnel on the Xicheng Railway, constructed by China Railway Second Bureau, officially entered the main tunnel. This is the first time that the Sichuan section has entered the main tunnel through the inclined shaft for construction. "The inclined shaft of the tunnel is a Class I risk tunnel, which needs to overcome difficulties such as high cold, water inrush, and soft rock mass. The project department strengthens the monitoring and measurement of the entire process of the tunnel and surface settlement observation to ensure the smooth progress of tunnel construction." The person in charge of the Xicheng Railway Project Department of China Railway Second Bureau told reporters. It is reported that the newly built Xicheng Railway has a total length of 832.9 kilometers, of which 172.6 kilometers are newly built within Sichuan Province, with a designed speed of 200 kilometers per hour. After completion, the connection between the Silk Road Economic Belt and the Yangtze River Economic Belt will be strengthened to promote coordinated regional economic development. In addition, the reporter learned that many places are seizing the opportunity of issuing additional treasury bond and planning a new batch of major projects around major water conservancy, emergency equipment, urban flood control and waterlogging drainage and other fields. Some regions have already started the preliminary work of project construction. Major projects have a large investment volume and high correlation, which has a significant driving effect on investment. Since the beginning of this year, the contribution rate of major project investment has increased. According to the data of the National Bureau of Statistics, in the first 10 months of this year, the investment in projects with a total planned investment of 100 million yuan or more increased by 9.9% year on year, and the growth rate was 7.0 percentage points higher than the total fixed assets investment; The contribution rate to the growth of all fixed assets investment increased by 3.8 percentage points over the previous three quarters. Major projects are not only the cornerstone of stable investment, but also the backbone of promoting industrial upgrading. In the recent intensive construction of major projects in multiple regions in the fourth quarter, industrial projects have become the top priority. On November 24th, key projects in the fourth quarter of Xi'an began construction, with a total investment of 45.726 billion yuan for 69 projects and an annual investment of 5.787 billion yuan. Among them, there are 41 industrial projects, especially 30 advanced manufacturing and innovation capacity enhancement projects, mainly including the high-tech intelligent manufacturing base project in the High tech Zone, the development of titanium fiber gas diffusion layer for PEM electrolysis water hydrogen production in the Economic Development Zone, and
