Examines the influence of big data policy on innovation in Chinese cities, suggesting positive effects.
When regions enhance the development of big data, are innovative activities affected? Via a DID framework and using panel data for 293 cities over the period 2009–2019 in China, this research analyzes innovation output change before and after cities became a part of the Big Data Comprehensive Pilot Zone (BDPZ). We document that the BDPZ policy facilitates financial-resource agglomeration and rational allocation, thereby stimulating local technological innovation. After further analysis, we show that heterogeneity exists in different patents and cities. Our paper offers evidence for the innovative effects of data resource in the field of economics.
