The smart city: a new solution to urban shrinkage? Evidence from China

While urban shrinkage has extensively befallen cities around the world, the current responses to urban shrinkage have been regarded as deficient and required optimization to help shrinking cities achieve sustainable economic growth and higher quality of life. This paper deploys difference-in-difference (DID) and successfully finds, based on China's national smart city pilot projects, significant effects of smart city development on shrinking cities in catalyzing sustainable economic growth by upgrading and diversifying local industries, promoting economic growth, and providing a better quality of life for citizens through improved wages, enhanced urban environment and public service.
