数实融合能否提高城市遭遇气温冲击时的经济韧性OA

As the core carriers of macroeconomic operations,cities' levels of economic resilience are not only crucial for regional risk prevention and control effectiveness but also vital for constructing a new development paradigm and promoting high-quality economic development.Digital-real economy integration represents a key initiative driving industrial transformation,providing foundational tech-nological conditions for urban industrial upgrading and economic development.Against the backdrop of the normalization of extreme temperature events,whether digital-real economy integration can effectively enhance urban economic resilience requires thorough inves-tigation.Accordingly,this study utilized annual data of prefecture-level and above cities in China from 2010 to 2022 to calculate the lev-els of temperature shocks,digital-real economy integration,and economic resilience faced by each city.Taking the interaction term of temperature shock and digital-real economy integration as the core explanatory variable and urban economic resilience as the explained variable,this study empirically examined the impact and mechanisms of digital-real economy integration on urban economic resilience under temperature shocks using a fixed effects model.It further analyzed its heterogeneity and threshold effects.The findings indicated that:① Digital-real economy integration helped improve urban economic resilience when facing temperature shocks.This conclusion remained robust after a series of robustness tests and endogeneity treatments.② Mechanism analysis revealed that under temperature shocks,digital-real economy integration could significantly enhance urban economic resilience through talent agglomeration effects,in-dustrial structure rationalization effects,and government digital governance effects.③ Heterogeneity analysis showed that the positive impact of digital-real economy integration when facing temperature shocks was more pronounced for inland cities,large and medium-sized cities,and cities with relatively well-developed digital infrastructure.④ Threshold effect analysis found that when temperature shocks were relatively small,digital-real economy integration could substantially improve urban economic resilience;however,when temperature shocks intensified,although digital-real economy integration could still significantly enhance urban economic resilience,the magnitude of improvement diminished.Therefore,governments should accelerate the process of digital-real economy integration,im-prove its regulatory mechanisms,and fully leverage its positive effects in stabilizing the economy and promoting development,thereby fostering the sustained and steady improvement of urban economic resilience.
