摘要：
This paper aims to improve our understanding of the constraints that heterogeneous firms face in expanding and maintaining their supplier base and in responding to unanticipated shocks to this base. Based on highly disaggregated firm-productcountry trade data, we analyze the evolution of Chinese firms’ sourcing decisions in the wake of China’s entry into the WTO in 2001 and document three stylized facts using anti-dumping (AD) investigations as unanticipated trade shock. We next build a simple model of firm’s sourcing search capacity to explain the observed supplier network adjustment among Chinese firms. To test the model predictions, we examine the impact of China’s AD investigations towards other countries’ exported goods on Chinese firms’ import supplier network decisions (entry and exit of import origin markets, other than the targeted sourcing origins) for both targeted and non-targeted imports. We find that once subject to AD shock, firms are more likely to explore new origins and also more likely to exit existing origins for targeted imports, while they become more sluggish about entry and exit decision for nontargeted imports. Firms show more churning in import sourcing supplier network adjustment in terms of entry and exit for targeted imports, but the opposite pattern obtains for non-targeted imports. Moreover, the importing supplier network response to AD shock presents significant heterogeneity across firms. Combining trade data with firm-level production data, we find that small, less productive firms or firms with smaller supplier base more actively adjust import sourcing supplier network on both targeted and non-targeted imports when facing AD shock, while large, more productive firms or firms with greater supplier base show more modest churning in their sourcing supplier network adjustment。
