China’s Greater Bay Area (GBA), detailed in my last blog, appears an obvious magnet for inward foreign direct investment (FDI) and catalyst for outward FDI (OFDI). Beijing’s backing, infrastructure improvements, supportive government science and technology (S&T) policies, the GBA’s surfeit of supply networks, and the GBA’s scale and diversity should attract inward FDI (IFDI). The GBA’s role as a financial center and the relaxation of barriers to outward capital flows promise greater OFDI. Some question the GBA’s ability to realize its lofty aims given myriad barriers to internal flows, the vagueness of government plans, and dearth of true technology leaders.
