AI and robotics as drivers of China’s urban innovation

Few studies have examined the economic consequences of deploying artificial intelligence (AI) and robotics in less-developed cities, where policies have often failed. To address this gap, we analyse a panel of 270 Chinese cities (2009–2019) using ordinary least squares (OLS), instrumental variable two-stage least squares (IV-2SLS) and quantile regression techniques. We find that AI and robotics significantly promote technological innovation in China, with especially pronounced implications for cities at or below the technological frontier. These technologies also enhance the returns to science and technology (S&T) investment. Its novelty lies in framing AI and robotics as policy substitutes and tools for narrowing innovation divides among Chinese cities.
