智慧城市建设能否成为经济增长新动能?

Can the Smart City Construction Become the New Momentum of Economic Growth?

智慧城市作为一种新的城市发展模式,自试点建设以来备受关注。科学评估智慧城市建设的作用,对于构建智慧城市、促进经济增长具有重要作用。基于2005—2016年中国171个地级城市的面板数据,在机制分析的基础上,运用双重差分方法实证检验智慧城市建设如何影响经济增长及其作用大小。研究发现:与非智慧城市相比,智慧城市建设显著促进了智慧城市地区经济发展,能够为地区经济发展提供新动能,平均而言,政策试点后,智慧城市经济增长显著高于非智慧城市5.4~5.9个百分点;智慧城市建设运用现代信息技术,通过优化资源配置、提高经济集聚水平、促进产业结构升级三个机制带动地区经济增长;智慧城市促进经济增长的作用随着城市人力资本水平提高、政府干预水平降低、金融发展水平及信息化水平提高而增强。研究结论对继续推动智慧城市建设、构建新型城市发展模式以促进经济增长具有重要的政策含义。

As a new urban development mode,smart city has attracted much attention since the pilot construction.Scientific evaluation of the role of smart city construction plays an important role in building smart city so to promote economic growth.Based on the panel data of 171 prefecture level cities in China from 2005 to 2016,on the basis of mechanism analysis,this paper uses the difference-in-differences method to test how the construction of smart city affects economic growth.The mechanism analysis shows that the construction of smart city can achieve economic growth through allocation effect,structure effect and agglomeration effect.The empirical analysis shows that compared with non-smart cities,smart city construction has significantly promoted the regional economic development of smart cities and can provide new impetus for regional economic development.On average,after the policy pilot,the economic growth of smart cities is significantly higher than that of non-smart cities by 5.4-5.9 percentage points;smart city construction uses modern information technology to improve the economy by optimizing resource allocation.The three mechanisms of agglomeration level and industrial structure upgrading drive regional economic growth;the role of smart city in promoting economic growth increases with the improvement of human capital level,the reduction of government intervention level,the improvement of financial development level and informatization level.The conclusion of this paper has an important policy meaning to continue to promote the construction of smart city and build a new urban development model to promote economic growth.
