演讲内容简介:

The productivity effect of public infrastructure investment is controversial in the literature using aggregate data, mainly due to reverse causality. To address the identification issue, this paper develops a model of endogenous productivity in a firm-level production function, and matches Chinese firm-level production data with province-level infrastructure investment data. A structural model is employed to further distinguish the long-run productivity effect from the short-run Keynesian demand effect of public investment. The estimated rates of return of public infrastructure investment are 9.2% and 2.5%, respectively before and after controlling for the demand effect. The returns triple once national spillover effects are taken into account. Firm-level evidences are consistent with a mechanism in which public infrastructure investment functions as a catalyst in facilitating resource reallocation from less to more productive firms.
