報(bào)告摘要：
This paper investigates the role of trade policy uncertainty (TPU) on resource allocation across heterogeneous Chinese producers and aggregate productivity. Using detailed Chinese data, we document that (i) simple measure of labor misallocation declined sharply as China joined the WTO and (ii) the largest declines occurred in industries with larger reductions in TPU. We rationalize these patterns with a model of input demand under policy-driven demand uncertainty among heterogeneous firms. The model implies that (i) the expected firm-level misallocation is increasing in the degree of TPU and (ii) the expected degree of misallocation is decreasing in firm size. Using China’s accession to the WTO as an exogenous change in the degree of trade policy uncertainty faced by Chinese producers, we test the model’s predictions and quantify the implied change in aggregate productivity due to the reduction in TPU. Consistent with the model predictions we find that the WTO accession reduced input misallocation by 3.2 percent in the average Chinese firms, gains were larger in industries facing greater TPU uncertainty and among China’s largest manufacturers. In aggregate the reduction in TPU induced by WTO accession accounted for 12% increase in aggregate productivity through improved resource allocation alone.
