The Influence of Demand-Based Policy Instruments on Urban Innovation Quality—Evidence from 269 Cities in China

Abstract

Enhancing the quality of urban innovation is a powerful strategy for advancing urban sustainability. A strong public innovation policy is a crucial building block for advancing urban innovation quality. This study identifies innovative procurement instances from over 640,000 public procurement contract data through textual analysis to investigate how urban innovation quality could benefit from demand-based policy instruments. The study’s findings indicate the following: (1) It provides evidence that the adoption of public innovation procurement has a significant impact on urban innovation quality, suggesting an inverse U-shaped relationship between the two. (2) Heterogeneity analysis reveals public innovation procurement stimulates urban innovation quality more remarkably in cities with provincial status and provincial capitals, as well as in eastern cities. (3) We discovered that it is not possible to increase the quality of urban innovation in the city when human capital in the city is performing poorly and when there is also a lack of external technology and entrepreneurial activity. Finally, this paper argues that our findings also provide important insights for the development of proactive innovation policy instruments, the construction of innovative cities, and the realization of sustainable development in countries around the world, especially in developing countries.
