Uncertainties,Imitative Behaviours and Foreign R&D Location: Explaining the Over-concentration of Foreign R&D in Beijing and Shanghai within China

This study examines the location of foreign research and development (R&D) establishments in China and reveals that such facilities are overly concentrated in Shanghai and Beijing, the two first- tier cities. We argue that the spatial concentration of R&D in Shanghai and Beijing is more intense than what can be expected based on the spatial concentration of foreign investment, science and technology resources and general economic activities. The spatial concentration is also greater than what is observed in more developed countries. This degree of concentration cannot be convincingly explained by the conventional, rational choice model that relies mostly upon factors such as market size, labour costs and infrastructure, among others. Our analysis suggests that site location decisions are also the product of imitative behaviours among decision makers faced with uncertainties and multiple risks, particularly in a transitional economy such as China's. We further discuss the implications for second-tier cities in competition for foreign R&D investment, suggesting that these cities should aggressively market their cities to foreign investors in order to reduce the perceived risks undermining their ability to attract R&D. We also speculate that as foreign investors become more knowledgeable about the rest of China, more companies will begin to establish R&D facilities in such second-tier cities.
