文章基于我国2009—2021年282个地级及以上城市面板数据测度了各城市资源错配指数，并采用双重差分法实证分析了智慧城市建设对城市资源错配的影响。研究结果表明：智慧城市建设能够改善城市资源错配，其通过降低政府干预水平和提高区域技术创新水平改善资源错配。异质性分析发现：中部地区智慧城市建设对资源错配的缓解效应显著，东部地区和西部地区智慧城市建设对资源错配的缓解效应不显著；智慧城市建设对资源型城市资源错配的缓解效应显著强于非资源型城市。在新发展格局下，应因地制宜建设智慧城市，积极发挥政府的引导作用，提高企业科技创新能力，实现资源优化配置。

This paper empirically examines the impact of smart city construction on urban resource mismatch based on the panel data of 282 cities at prefecture level and above in China from 2009 to 2021, and on the basis of measuring the resource mismatch index of each city, using double-difference method, heterogeneity analysis and mediation effect analysis. It is found that, firstly, China's smart city construction can improve urban resource mismatch, and the results remain robust through the test. Secondly, mechanism analysis finds that China's smart city construction improves resource mismatch by reducing the level of government intervention and increasing the level of regional technological innovation. Thirdly, heterogeneity analysis finds that the mitigation effect of smart city construction on resource mismatch is most significant in the central region, and the improvement effect of smart city construction is not significant in the eastern and western regions. The mitigation effect of smart cities on resource-based cities is significantly better than that on non-resource-based cities. Therefore, under the new development paradigm, it is essential to build smart cities in a location-specific manner, innovate in the development of smart cities, intervene in the market in a rational way, promote the flow of factors, and enhance the efficiency of resource allocation.
