To explain countries’ varying participation in the Belt and Road Initiative, this chapter begins with a discussion of recipient country characteristics that impact the demand for Chinese spending, including the political regime, clientelism, and the public-private orientation of the corporate sector. It then discusses the supply-side factors that influence Chinese foreign spending, including the Chinese Communist Party (CCP), state-owned entities (e.g., SOEs), and private firms. Finally, it evaluates the compatibility of these demand and supply characteristics. The key prediction is that electoral autocracies will display the strongest compatibility with Chinese foreign construction spending. This is amplified when the leaders of these regimes have a weak or insecure hold on power. Electoral autocracies are also predicted to be the most avid adopters of Chinese standards stemming from their eagerness for Chinese infrastructure spending.
