Cross-industry growth differences with asymmetric industries and endogenous market structure

摘要

We develop a two-industry R&D growth model with a free-entry endogenous market structure to evaluate the impact of industrial fundamentals on cross-industry differences of TFP growth and R&D intensity. Endogenous market structure in our model allows the firm's market size to respond to the firm's entry and exit which complements the models with an exogenous market structure in the previous literature. We find that surprisingly, an industry with a relatively high R&D productivity or appropriability exhibits "relatively" low in-house innovation growth and R&D intensity during transition. Moreoever, we examine the effects of R&D subsidies and patent breadth policies on industry differences by implementing both asymmetric and symmetric policy rules. We find that only asymmetric R&D subsidies have impacts on TFP growth and R&D intensity differences.
