In the process of identifying the effect of institutional quality, the roles of other factors such as ownership types and market structures are revealed, which provides interesting insight into firms ＂ R＆D behavior. The key findings suggest that institutional quality positively affects the decision offirms to engage in R＆D activities. Once firms start to engage in R ＆D, the subsequent expansion of firm-level R ＆D intensity depends on factors such as market structure. Therefore, strengthening domestic institutional quality is the first critical step towards the goal of building a knowledge-intensive economy in China. Efforts to nurture market development are also important for achieving this goal.展开更多
