Investment Rating - The report maintains an "Overweight" rating for the construction and engineering sector, as well as for building materials [6]. Core Insights - Traditional infrastructure investment is expected to show stable growth, while emerging industries and strategic regional investments are anticipated to have high elasticity [1][3]. - The report emphasizes the importance of urban renewal as a key area for improving living standards and highlights the robust demand for investment in emerging industries [1][3]. - The report identifies that the economic provinces are expected to play a significant role in driving investment, with regions like Xinjiang, Tibet, and Hainan showing considerable investment elasticity [4][10]. Summary by Sections Overview of Infrastructure Investment - Traditional infrastructure investment is projected to improve slightly, with energy sectors like nuclear power, wind power, and power grids experiencing high demand [1][3]. - Urban renewal projects are highlighted as critical for addressing social needs, with a focus on upgrading old urban areas and improving public housing [3]. Regional Investment Dynamics - Economic provinces are expected to lead investment efforts, with strong fiscal capabilities observed in regions like Zhejiang [4][10]. - High-risk areas are showing signs of recovery, with investment plans for 2025 indicating a positive trend after two years of risk management [4][10]. Sector-Specific Insights - The construction sector is expected to maintain a stable demand, with leading state-owned enterprises and quality local state-owned enterprises likely to benefit from valuation recovery [5]. - The report identifies two main investment directions: the dividend value of leading construction companies and the growth opportunities driven by industrial services in data centers and cleanroom engineering [5]. Energy and Transportation Investment - Energy construction is expected to see high growth in nuclear power and wind power, while solar energy installations may decline [3][48]. - Transportation infrastructure, particularly railways, is projected to remain robust, while road investments are under pressure due to policy constraints [32][42].

Core Viewpoint - The Tianshan Victory Tunnel, the world's longest highway tunnel, has successfully connected after five years of construction, significantly reducing travel time and embodying the principle of "ecological priority and green development" [1][5]. Group 1: Project Overview - The Tianshan Victory Tunnel spans 22.13 kilometers and reduces the travel time across the Tianshan Mountains from 3 hours to 20 minutes [1]. - The tunnel is a critical component of the G0711 line, which connects Urumqi to Yili, and it traverses 16 geological fault zones with a maximum depth of 1112.6 meters [1][5]. Group 2: Environmental Protection Measures - The project team established strict environmental protection standards, including a dust collection rate of over 99% for concrete production and 100% recycling of construction wastewater [5][12]. - Innovative dust removal systems were implemented to ensure that dust generated during construction does not harm the surrounding environment [6][8]. - Three wastewater treatment plants were constructed, with a combined daily processing capacity of 17,500 cubic meters, ensuring that treated water meets surface water quality standards [13][12]. Group 3: Wildlife Conservation Efforts - The project includes measures to protect local wildlife, such as constructing oval-shaped water pools to facilitate access for animals and designing tunnels and bridges to maintain animal migration routes [16][17]. - Approximately 116 kilometers of the project route features rich biodiversity, with 17 tunnels and 36 large bridges designed to minimize ecological disruption [17][18]. Group 4: Community and Stakeholder Engagement - The project management emphasizes the importance of ecological protection alongside construction, ensuring that local communities and wildlife are respected throughout the process [18][15]. - The construction team actively engages with local wildlife, demonstrating a commitment to coexistence and environmental stewardship [16][18].
