R&D Investment, Exporting, and Productivity Dynamics
估计了一个生产者决定投资研发和出口的动态结构模型，发现这两种活动都能正向影响未来生产率，并促使更多企业自我选择参与，从而进一步推动生产率提升。
This paper estimates a dynamic structural model of a producer's decision to invest in R&D and export, allowing both choices to endogenously affect the future path of productivity. Using plant-level data for the Taiwanese electronics industry, both activities are found to have a positive effect on the plant's future productivity. This in turn drives more plants to self-select into both activities, contributing to further productivity gains. Simulations of an expansion of the export market are shown to increase both exporting and R&D investment and generate a gradual within-plant productivity improvement.
