基于面板Tobit和面板门槛模型的数字政府建设对城市生态韧性的影响效应
Impact of digital government construction on urban ecological resilience based on panel Tobit and panel threshold models
摘要
Abstract
Using panel data of 279 Chinese cities from 2018 to 2021,the panel Tobit and threshold models were employed to examine the impact and mechanisms.Results showed that:(1)Digital government construction significantly boosted urban ecological resilience;(2)Digital government construction promoted ecological resilience by facilitating industrial structure upgrading;(3)A nonlinear marginal increasing effect emerged as ecological resilience was improved.The results provided empirical evidence for the positive correlation between digital government construction and ecological resilience.关键词
