摘 要：以2023年我国38个体育城市数字经济与全民健身发展的截面数据为实证依据，通过门槛效应模型，探讨数字经济驱动体育城市全民健身智慧化转型的门槛效应与作用特征，旨为促进城市全民健身智慧化发展提供参考。研究表明：(1)数字经济的快速发展有效驱动我国体育城市全民健身智慧化转型且存在显著的门槛效应；(2)随着城市经济稳步发展、数字基础设施迭代升级、科技创新融合驱动、产业结构能级跃迁，城市全民健身智慧化水平逐步提升，呈现明显的单门槛特征；(3)数字经济对全民健身智慧化转型的驱动作用强度呈现出典型“南强北弱”的地区城市异质性。地区数字经济、科技创新水平与产业动能结构是驱动城市全民健身智慧化转型的核心门槛。建议：以数字经济驱动体育城市发展，促进全民健身智慧转型；以科技创新赋能产业结构升级，提升全民健身供给效能；以政策引领统筹区域联动发展，推动城市全民健身协同转型。
关 键 词：数字经济；体育城市；全民健身；智慧化转型；门槛效应

Abstract: Based on cross-sectional data of digital economy and national fitness development from 38 Chinese sports cities in 2023, this study employs a threshold effect model to examine the threshold effects and influencing characteristics of the digital economy in driving the intelligent transformation of national fitness in sports city, which aims to provide insights for advancing the intelligent development of urban national fitness. The findings reveal that: (1) The rapid development of the digital economy significantly effectively drives the intelligent transformation of national fitness in Chinese sports city, and also presents notable threshold effects. (2) As urban economies grow steadily, basic digital infrastructure gradually upgrades, the integration drive between science and technology and innovation, and industrial structures largely enhance, the intelligent transformation level of national fitness in urban improves progressively, which demonstrates a distinct single-threshold feature. (3) The driving effect and intensity of the digital economy exhibits obvious regional urban heterogeneity, which is characterized by a "stronger in the south, weaker in the north" pattern. Regional digital economy, innovation capacity of science and technology, and industrial dynamics structure are identified as the core threshold to drive this transformation. The study proposes the following recommendations: driving the development of sports city by digital economy to promote intelligent transformation of national fitness; empowering industrial structure upgrade by the innovation of science and technology to enhance the supply efficiency of national fitness; and coordinating regional collaborative development by policy guide to promote coordinated transformation of national fitness in urban.
