智慧城市建设能否提升居民幸福感--基于中国健康与养老追踪调查数据的实证分析

Can the Construction of Smart Cities Improve the Happiness of Residents:An Empirical Analysis Based on Data from CHARLS

基于中国健康与养老追踪调查(CHARLS)数据,利用双重差分法(DID)评估了智慧城市建设对居民幸福感的影响,并运用倾向得分匹配法(PSM)进一步进行了验证。结果表明,智慧城市建设显著提升了居民幸福感,平均而言可以提升居民幸福感7.2%。智慧城市建设能够通过减少环境污染、降低犯罪率和革新信息技术提升居民幸福感。这种促进作用因城市所在区域和行政等级不同而存在明显差异,位于东部、中部地区和具有高行政等级的智慧城市建设对居民幸福感的影响更大。为此,国家应继续推进智慧城市建设,以解决生态环境问题为突破口,加快互联网等基础设施的建设,进而增加居民福祉。

Based on the data from the China Health and Retirement Longitudinal Study(CHARLS),this paper uses the double difference method to evaluate the impact of smart city construction on residents'happiness,and further verifies the result by using the propensity score matching method.Results show that the construction of smart citics has significanly improved residents'happi-ness by 7.2%averagely.Smart city construction can improve residents'happiness by reducing environmental pollution,reducing crime rate and innovating information technology.There are obvious differences in this promotion efct due to different regions and administrative levels of cities.The construction of stmart cities in the eastern and central regions and with higher administrative levels has a greater impact on residents'happiness.To this end,the country should keep promoting the construction of smart citices,take the solution of cological and environmental problems as a breakthrough,and accelerate the construction of infrastructures including the Intermnet.etc.s0 as to improve the well-being of residents.
