We find that firms pursing a product differentiation strategy have more R＆D spending than those with a cost leadership strategy. In addition, we document a positive effect of R＆D spending on firms＇ future performance if they adopt a product differentiation strategy. Meanwhile, for the firms that adopt a cost leadership strategy, the relationship between R＆D spending and firm performance resembles an inversed U-shape. Furthermore, we find this inversed U-shape relationship only exists for non-state-owned firms. Overall, this paper provides guidance and useful suggestions on the efficient allocation of R＆D resources for Chinese manufacturing firms.展开更多
