Smart cities improve services for businesses, among many other benefits. A comprehensive understanding and effective utilization of these advantages is crucial for promoting business development. Using panel data from Chinese listed companies (2010-2020), this study employs a multi-stage DiD model to investigate the impact of smart cities on corporate earnings management. The findings indicate that the smart city pilot policy has significantly reduced corporate earnings management. Further analysis suggests that smart cities primarily reduce earnings management by improving firms' external information environments. Additionally, the results show that the policy impact of smart cities is more significant in regions with lower regulatory intensity or higher marketization levels, compared to regions with higher regulatory intensity or lower marketization levels. Similarly, firms in less concentrated markets or those more closely related to smart city development tend to experience greater reductions in earnings management due to smart city construction, unlike firms in more concentrated markets or those less involved. Finally, this paper offers several brief suggestions.
智慧城市在提高企业服务水平等诸多方面具有显著优势。全面理解并有效利用这些优势，对于促进企业发展至关重要。本文利用中国上市公司（2010-2020 年）的面板数据，采用多阶段 DID 模型实证检验了智慧城市对企业盈余管理的影响。研究结果表明，智慧城市试点政策显著降低了企业盈余管理水平。进一步分析表明，智慧城市主要通过改善企业外部信息环境来降低盈余管理程度。此外，研究结果显示，与监管强度较高或市场化水平较低的地区相比，在监管强度较低或市场化水平较高的地区，智慧城市的政策效果更为显著。同样，与处于更为集中的市场或与智慧城市发展关联度较低的企业相比，处于竞争程度较低的市场或与智慧城市发展关联度较高的企业，由于智慧城市建设，其盈余管理程度的降低更为显著。最后，本文提出了几点简要建议。
