五年协同铸就万亿集群：成德眉资同城化重塑区域经济版图

Core Viewpoint - The Chengdu-Deyang-Meishan-Ziyang (CDMZ) urban integration development is emerging as a new engine for high-quality development in Western China, focusing on industrial clusters and breaking administrative barriers to create a modern industrial system through collaborative efforts over five years [2][4]. Group 1: Industrial Collaboration - The four cities have implemented a "functional complementarity and differentiated development" strategy to address their respective industrial shortcomings, leading to a series of effective explorations and practices [3]. - Chengdu focuses on research and design, Deyang aims to build a world-class heavy equipment manufacturing base, Meishan is developing a new materials industry hub, and Ziyang is cultivating a rail transit cluster and specialized dental industry [3]. Group 2: Economic Growth and Industrial Clusters - The economic output of the Chengdu metropolitan area is projected to grow from 2.24 trillion yuan in 2020 to 2.98 trillion yuan by 2024, with an average annual growth rate exceeding national and provincial averages [4]. - By 2025, the output value of nine key industrial chains in the Chengdu metropolitan area is expected to exceed 1.2 trillion yuan, with 14 national-level industrial clusters, including electronics and equipment manufacturing, reaching over 1 trillion yuan in scale [4]. Group 3: Infrastructure and Connectivity - Over five years, more than 200 billion yuan has been invested in transportation projects, significantly reducing average commuting time between the four cities from 2 hours to 1 hour, thus facilitating industrial collaboration [6]. Group 4: Public Services and Talent Mobility - The "Chengdu-Deyang-Meishan-Ziyang Unified Service" initiative has enabled 505 high-frequency services to be processed across cities, enhancing talent mobility and providing strong support for industrial development [9]. Group 5: Future Development and Goals - The CDMZ urban integration is set to accelerate towards higher levels of development, focusing on innovation collaboration, deepening open cooperation, and optimizing ecological systems, with plans to establish two world-class industrial clusters and four trillion-yuan industrial clusters by 2030 [10][13].
