The Effects of Government-Industry R&D Programs on Private R&D: The Case of the Small Business Innovation Research Program
研究政府产业研发补贴是否增加私人研发，利用小企业创新研究项目数据发现补贴完全挤出了企业自筹研发支出。
I ask whether government-industry commercial R&D grants increase private R&D. Regressing some measure of innovation on the subsidy can establish a correlation between grants and R&D, but it cannot determine whether grants increase firm R&D or whether firms that do more R&D received more grants. Using a dataset of firms involved in the Small Business Innovation Research (SBIR) program, I estimate a multi-equation model to test these hypotheses. Firms with more employees and that appear to do more research win more SBIR grants, but the grants do not affect employment. Moreover, I find evidence that the grants crowd out firm-financed R&D spending dollar for dollar.
