This chapter aims to explore the importance of the convergence and collaboration of the internet of things and blockchain in enabling the development of smart cities. It will capture the strong link between the burgeoning advanced technology and China's fast-growing smart cities. In addition, the authors used the CiteSpace bibliometric tool to analyse the core journals related to smart cities, IoT, and blockchain in WoS and CNKI operations and visualise the relationships between the literature as a scientific knowledge map. The research topic in this chapter focuses on the keywords with the highest frequency and determines the research frontier and trend. This chapter will further explore the roles of the government in promoting the integration of the internet of things and blockchain in the development agenda of industrial infrastructure and smart cities through policies (i.e., institutions).
