由规模扩张转向内涵式发展，建设宜居城市这么做！

Group 1 - The central urban work conference emphasizes the integration of population, industry, urbanization, and transportation planning to optimize urban spatial structure as a task for building livable cities [1] - China's urban spatial structure optimization has shifted from scale expansion to quality enhancement, focusing on efficient allocation of spatial elements and systematic optimization of functional systems to address "urban diseases" and promote high-quality urban development [2][3] Group 2 - By 2024, China's urbanization rate is projected to reach 67%, with urban development transitioning from scale expansion to quality improvement [2] - The transformation towards a multi-center network structure aims to alleviate excessive concentration in central urban areas, as seen in Beijing's adherence to population limits and Chengdu's establishment of industrial ecological zones [2] - From 2019 to 2024, 280,000 old residential communities are set to be renovated, benefiting over 120 million residents, focusing on enhancing community facilities and improving living quality [2] - The implementation of 90 sponge city pilot projects aims to develop flood resistance solutions and restore urban ecological networks [2] Group 3 - Urban spatial optimization is crucial for enhancing urban competitiveness and residents' quality of life, yet challenges such as land resource imbalance and historical preservation conflicts persist [3] - Future strategies for optimizing urban spatial structure include establishing a dynamic monitoring and evaluation mechanism for population, industry, and space, and promoting coordinated development among urban agglomerations [3] - The need for smart governance using big data to optimize traffic flow and public service layout is highlighted to improve spatial efficiency and convenience [3] Group 4 - The promotion of industrial spatial optimization involves collaborative mechanisms for industrial land use, policy support, and urban-rural integration to enhance regional functional synergy [4] - Companies are encouraged to seize policy opportunities to participate in the development of balanced urban structures, enhancing spatial efficiency through initiatives like "industrial upgrading" and "mixed-use land" [4] - The exploration of "ecology+" models and the use of technology to improve spatial governance efficiency are essential for creating a green, low-carbon, and innovative urban space [4]
