The Effects of the Temporary Protection on Firm Performances: Evidence from the Steel Industry in Vietnam
利用2010-2017年越南企业调查面板数据，研究临时贸易保护对钢铁行业及其下游用户的影响，发现保护政策增加了受保护企业的销售额，但损害了下游企业的销售、利润和生产率，尤其对小企业影响更严重。
Trade protection may have significant impacts on sectors other than those targeted by the protection policies, especially when the target sector produces goods that are essential inputs to downstream sectors. Using panel Vietnamese enterprise surveys from 2010 to 2017, this paper examines whether temporary trade protection has a significant impact on the steel sectors and downstream users of steel. We find that during the trade protection period to the steel sector, this policy increased sales of protected firms but hurt downstream firms. Particularly, trade protection has significant impacts on sales, profit, and productivity of downstream firms in the sectors that use steel intensively as their inputs. Additionally, these adverse effects of protection are more severe to small downstream firms.
