Currently, the Biden administration is adopting an S&T competition strategy toward China based on the “small yard, high fence” tactical logic, which involves three pillars: investment to make America strong, alignment to get things under control, and competition to weaken China. In the current context of the China–U.S. competition entering a new normal, five inherent contradictions, namely, the gap between strategic expectations and policy effects, shortfall between action capabilities and policy objectives, push-and-pull between strategic deployment and domestic politics, clash between strategic intentions and the S&T innovation ecosystem, and divergences between American priorities and the interests of American allies, will dictate how this administration will implement its S&T competition strategy toward China.展开更多

In this paper we first construct an index system for evaluating competitiveness of Chinese cities based on modern competitive advantage theory. With principal component analysis and cluster analysis methods, we compare the factors affecling cities’ integrated competitiveness in 1990 and 1997. We find that four major factors are capital (including investment, FDI and urban financial revenue ), urban ithestructure (transporiation and communication, urbanization level, education etc. ), industrial performance and structure, degree of market openness and that these factors have become more advanced and complicated since 1990. Most Chinese cities are transforming from productive factors-oriented type to investment-oriented type and a few are becoming innovation oriented. The integrated competitiveness is closely related to cities’ scale, urban function, regional policy and degree of market openness and displays an uneven spatial pattern. The difference between the south and the north and the difference between the west and the east co-exist bul the former has been more larger. Finally, we discuss the mechanism behind the pattern and attribute the unevenness to change of factors dominating the cities’ compehtiveness regional innovation capacity and geographical differenceof traditional culture.展开更多
