"京津冀人才流通网络呈现出'核心—边缘'的特征，以北京、天津为双核心，衡水和廊坊成为推动人才 双向流动的节点城市，保定和石家庄的人才吸引力正逐渐增强，成为人才承接区。"近日，一位参与京 津冀发展问题调研的专家在"江山论坛"上指出，"河北其他城市如沧州、邯郸、承德则面临人才吸引力 减弱、人才外流的困境。" 协同发展进入"融合提效"新阶段 《京津冀协同发展蓝皮书》数据显示，2023年，京津冀地区研发人员数量较2014年增长了1.5倍，呈现 稳步扩张态势。特别是北京，其研发人才占京津冀总量的比重从2014年的53%提升至2023年的58%，形 成了单极强化的人才集聚格局。 然而，从规模以上工业企业研发人员分布来看，北京、天津两地合计占据了京津冀研发人员总量的"半 壁江山"，而河北各城市整体不足前两者的一半，区域性"多中心协同"格局尚未形成。 2025年10月30日下午，第二届"江山论坛"分论坛——"中国式现代化的京津冀协同发展实践"在中国人民 大学举行。 冯仕政指出，该战略强调交通、产业、生态、城镇建设与社会政策"五个协同"，有效推动了区域高质量 发展，为中国式现代化提供了重要的实践样本。 创新动能增强但区域均衡仍 ...

Core Viewpoint - The phenomenon of "shrinking cities" in China has gained attention as urbanization enters a new phase, characterized by population decline and economic restructuring, necessitating targeted development strategies and policy recommendations for sustainable urban development [1][48]. Group 1: Definition and Identification of Shrinking Cities - Shrinking cities are defined as urban areas experiencing sustained population loss and structural economic crises, requiring a multi-dimensional understanding [3][6]. - Identification standards for shrinking cities include a continuous decline in urban population over three years, economic growth below the national average, and mismatched urban expansion and population growth [7][10]. Group 2: Characteristics and Distribution of Shrinking Cities - There are 139 identified shrinking cities in China, with significant concentrations in the Northeast, particularly in Heilongjiang, where 12 out of 13 cities are classified as shrinking [10][11]. - Shrinking cities exhibit a paradox of spatial expansion despite population decline, with 93.03% of these cities still expanding their built-up areas [35][36]. Group 3: Causes of Shrinking Cities - Macro factors contributing to shrinking cities include population aging, low birth rates, and regional development imbalances, leading to resource and talent concentration in coastal areas [17][19]. - Micro factors include population outflow, a decline in job opportunities, and a stagnant real estate market, exacerbating the shrinking phenomenon [27][29]. Group 4: Transformation Paths for Shrinking Cities - Strategies for transformation include "smart shrinkage," focusing on quality and efficiency rather than mere expansion, optimizing urban space, and developing new industries [38][39]. - Specific development paths for resource-dependent cities involve leveraging local resources for new industries, while cultural tourism and ecological cities are emerging as viable options for others [40][41]. Group 5: Policy Responses - National policies emphasize the need for "smart shrinkage" strategies, optimizing administrative divisions, and avoiding blind expansion to enhance urban quality and competitiveness [43][44]. - Future policy recommendations include establishing monitoring mechanisms for shrinking cities, implementing differentiated support policies, and promoting regional collaboration for resource sharing [46][47].
