The impact of medical infrastructure on regional innovation: An empirical analysis of China's prefecture-level cities.

ABSTRACT

Because of public health emergencies, such as the COVID-19 pandemic, having an optimal medical infrastructure is an important way to maintain the normal operation of society and stimulate vitality in regional innovation. Based on the data on 260 cities at the prefecture level and above in China from 2001 to 2018, this paper investigates the characteristics and mechanisms of medical infrastructure on regional innovation. After a series of regressions, we robustly find that medical infrastructure has a significantly positive impact on regional innovation. In addition, based on the mediating effect model, the mechanism test shows that medical infrastructure can promote regional innovation through the channels of the natural population growth rate, educational level, and the environmental greening level. Finally, considering the urban heterogeneity, we find that the positive impact of medical infrastructure on regional innovation is reflected mainly in eastern and central cities, non-sub-provincial cities, and non-resource-based cities. These conclusions not only enrich the theoretical research on regional innovation from the perspective of medical infrastructure but also shed light on how to better promote regional innovation for China or even other countries.
