International Trade, R&D Spillovers and Productivity: Evidence from Indian Manufacturing Industry
利用印度制造业企业面板数据，研究贸易带来的研发溢出对生产率的影响，发现研发溢出显著提升生产率，且在技术密集型行业效果更强，企业设备投资能增强这一效应。
Abstract This paper examines the effect of trade facilitated R&D spillovers on the productivity of manufacturing firms in India, inter-sectoral variation in the effect on productivity and the importance of firms' investment in R&D, technology imports and plant and machinery in enhancing the productivity effect. Using firm level panel data, the study shows that R&D spillovers have a significant effect on productivity and that this effect is greater in technology-intensive industries. The paper also shows that firms' investment in plant and machinery enhances the productivity effect of R&D spillovers. The paper provides detailed micro-level evidence on the argument that trade openness promotes technological progress in developing countries.
