[Music] [Applause] I want you to imagine for a moment that you're an insect and you just woke up for the day and you're going out to get some breakfast. And along the way, you pass all kinds of plants and wild flowers. And you see all your neighbors out and about.And you're a respectable bug. So you smile and you wave to every single one of them. And there are a lot.In fact, 80% of all animal life on Earth is insects. And they are busy. In fact, because of their productivity, they generate about $577 billio ...

Core Insights - The article discusses the comprehensive development of the Yarlung Tsangpo River downstream hydropower project, led by China Yajiang Group, with a total investment of 1.2 trillion yuan and a planned capacity of 60 million kilowatts, aiming for an annual power generation of 300 billion kilowatt-hours [1][6]. Upstream Industry - The upstream high-end equipment manufacturing sector exhibits a multi-dimensional competitive landscape, with Dongfang Electric holding a 45% market share in the turbine sector, expected to capture over 40% of the turbine and auxiliary equipment value for the Yajiang project, translating to an order size exceeding 28 billion yuan [3][5]. - In the tunnel boring machine (TBM) sector, China Railway Construction occupies a dominant position with a 50% market share, anticipated to secure orders for 25 hard rock TBMs, accounting for 45%-68% of the total orders, with a median value of 3.675 billion yuan [3][5]. - The peak delivery period for high-end equipment is projected between 2028 and 2035, which will have a long-term stimulating effect on the industry chain [3][5]. Midstream Industry - The design and construction of hydropower projects face significant technical barriers and high industry concentration, with the Yajiang project expected to generate design contracts worth 24 billion yuan, based on a 2% design fee of the total investment [6][9]. - China Power Construction, as a leading player in global hydropower engineering, is expected to undertake over 50% of the main engineering volume for the Yajiang project, leveraging its expertise in complex geological engineering [8][9]. Downstream Industry - The Yajiang Group's electricity transmission primarily relies on "Tibetan electricity transmission," with over 70% of power sent out through ±1100 kV UHVDC technology, which allows for efficient long-distance transmission with losses below 10% [11][12]. - The investment in supporting transmission projects is estimated to exceed 240 billion yuan, contributing to a significant market opportunity in the UHV sector [12][14]. Supporting Services - The ecological restoration aspect of the Yajiang Group's operations focuses on smart monitoring technologies and ecological benefit transformation mechanisms, establishing a comprehensive ecological monitoring network [15][16]. - The fish species enhancement project has successfully bred rare fish species, contributing to biodiversity and receiving international recognition for its ecological restoration model [16][17].
