Throughout the history of world economic development, international capital flow is the only route to allocating flowing factors under the background of globalization, foreign direct investment (FDI) brings positive effects to push forward the host countrys economic growth. As many countries along the route of “OneBeltOne Road” (OBOR) are still in the early stage of economic development, FDI may help increase economic growth by facilitating their capital formation and raise the level of technology. Considering the complexities and discrepancies among the investment environment and economic development of many OBOR countries, attracting FDI become more challenging for them. The fundamental issue here is that these OBOR countries are mostly in the early development stage, which implies the lacking of normative standards for establishing a market economy system. With the Openingup Reform, China moved slowly but steadily and gradually accumulated its own reform experience, especially combining inductive institution evolution and compulsory institution evolution, leading to marketoriented reform and economic development pattern by incremental reform and other measures, which all provided experiences and references for the OBOR countries.
