洞察地铁运营里程增长盾构机市场需求稳增
受益于国内地铁建设的稳定发展，我国盾构机市场需求呈现攀升趋势。在2020年，该行业实现了500台的销售量，预计在2021年将达到460台。
盾构机是一种高效且安全的施工设备，能够进行隧道施工。由于其综合性能和较高的安全性，它们已经被广泛应用于公路隧道、海底隧道、铁路、城市下穿隧道和油气管道等领域。随着我国基建项目不断推进，盾构机市场需求持续攀升，行业得到快速发展.
市场分析显示，盾构机需求主要来源于地铁建设工程，这占比达到了七成左右。我国城市化快速发展中，加上新增地铁运营线路长度不断增长，在2020年达到最高，为1122公里，但在2021年受到政策调整和疫情影响，有所下滑，为970公里左右。随着新增运营线路长度的持续增加，盾构机应用需求也在持续上升.
根据新思界发布的《2022-2026年中国盾构机行业全面市场调研及投资分析报告》，我国已经拥有自主知识产权，并实现国产替代，同时开始向全球输出产品。在近几年的新基建项目推动下，我国盾constructing machine market demand growth, driving production volume increase. Since 2016, China's shield tunnel boring machine output has grown from approximately 400 units to around 660 units in 2020.
From the perspective of demand, shield tunnel boring machines are mainly used in subway construction. With the stable development of subway construction projects in China, the country's shield tunnel boring machine market demand is growing steadily. In addition to soft rock and hard rock types, soft soil and mixed face shields also have a certain market share.
In terms of industry concentration, before 2015, foreign enterprises such as Hitachi (Japan), Komatsu (Japan) and Herrenknecht (Germany) dominated the Chinese shield tunnel boring machine market. However, with increasing domestic R&D investment and technological advancements, Chinese enterprises have achieved indigenous innovation.
Currently, there is a high degree of concentration in the domestic market for this type of equipment; key players include China Railway Industry Corporation (CRIC) and Tianhe Heavy Industry Co., Ltd., accounting for approximately 39% and 33%, respectively.
Tianchen Heavy Industry is also a major player on both domestic and international markets; it accounted for about 14% domestically but had an overseas share exceeding that at home - reaching around one-quarter or more - by producing over two hundred units in last year.
An analyst from New Thinker said: "The application field of shield tunnel boring machines lies primarily within subway construction projects across China where rapid urbanization continues to drive infrastructure needs."
Thus concludes our report on how growing subway lines fuel increased demand for these critical pieces-of-equipment that help shape modern cities' underground networks.
