2025收缩型城市分析——139个城市正 “悄悄收缩”

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].
