Abstract
When cities develop rapidly, there are negative effects such as population expansion, traffic congestion, resource shortages, and pollution. It has become essential to explore new types of urban development patterns, and thus, the concept of the “smart city” has emerged. The purpose of this paper is to investigate the links between smart city policies and urban green total factor productivity (GTFP) in the context of China. Based on panel data of 200 cities in China from 2007–2016 and treating smart city policy as a quasi-natural experiment, the paper uses a difference-in-differences propensity score matching (PSM-DID) approach to prevent selection bias. The results show: (a) Smart city policies can significantly increase urban GTFP by 16% to 18%; (b) the larger the city, the stronger and more significant this promotion.
Highlights
Urban growth is a global trend, the world’s urban population will be close to 70% by 2050 [1].Following this world trend, urbanization is developing rapidly in China
This paper aims to study the impact of smart city policies on green total factor productivity (GTFP) from the perspective of an urban development pattern
0.592 in the treated group and is 0.406 in the control group). This result is a preliminary indication that smart city policies can promote urban GTFP
Summary
Urban growth is a global trend, the world’s urban population will be close to 70% by 2050 [1]. Following this world trend, urbanization is developing rapidly in China. China’s urbanization is mainly enacted through area expansion and population spatial agglomeration. This model will lead to population expansion, traffic congestion, resource shortages, and environmental degradation [3]. The 18th National Congress of the Communist Party of China clearly put forward the concept of “new urbanization”. Cities are implementing programs aiming to increase their sustainable development
