摘要 基于2005—2019年全国地级市面板数据,利用多时点DID方法对智慧城市建设提升城市宜居度的因果关系进行识别。研究发现:智慧城市建设可以显著提升城市宜居度,在经过安慰剂检验和PSM匹配的稳健性检验后,核心结论依然成立;机制检验表明,智慧城市建设可以通过资源配置效应、创新驱动效应和创业促进效应来促进城市宜居度的提升;异质性检验显示,城市区位、地理特征、人口规模和发展模式对政策反应有显著区别,东部城市、沿海城市、人口规模更大城市和非资源型城市受政策影响的效果更为显著。研究结论证实了智慧城市建设能够改善城市居民生活质量,提高城市宜居度。因此,加大创业创新人才的培养力度、推进新型基础设施建设、促进区域平衡发展,是提高人民生活品质、推动现代化城市建设和完善数字中国体系的现实有效路径。

Abstract: Based on the panel data of prefecture level cities in China from 2005 to 2019, this paper identifies the causal relationship between smart city construction and the improvement of urban livability by using the multi-point DID method. The study shows that smart city construction can significantly improve urban livability, and the conclusion remained valid after the placebo test and the robustness test of PSM-DID matching. Mechanism verification indicates that smart city construction can promote the improvement of city livability through resource allocation effect, innovation-driven effect and entrepreneurship promotion effect. Heterogeneity test reveals that there are significant differences in urban location, geographical characteristics, population size and development model to policy responses. Moreover, eastern cities, coastal cities, cities with larger population and non-resource-based cities are more significantly affected by the policy. This paper proves that the construction of smart cities can improve the quality of life of urban residents and enhance the livability of cities. Therefore, strengthening the training of entrepreneurial and innovative talents, promoting the construction of new infrastructure and promoting the balanced development of regions are realistic and effective ways to improve the quality of people’s life, promote modern urban construction and improve China’s digital system.
