内容提要:
This study examines how firms respond to export tax increases by adjusting sales across product and destination markets. We first built a multi-product multi-destination model to demonstrate how capacity-constrained firms translate negative tax shocks to specific product-destination markets into sales expansion to other product and destination markets. By exploiting a quasi-experimental export tax change setting and applying detailed firm and product-level trade data, we find strong evidence of this dual-dimensional market interdependence effect on Chinese exporters. Specifically, the results indicate that an increase in export tax for treated products of the firms is accompanied by significant increases in the firms’ export sales for the untreated products and total domestic sales. Further analysis demonstrates a decline in the marginal cost of production for treated firms in the post-treatment period, which affirms that production capacity constraints comprise the key mechanism for the detected market interdependence effects.
本研究考察了企业如何通过在产品市场与出口目的地市场之间调整销售额,来应对出口关税上调的冲击。我们首先构建了一个多产品、多目的地理论模型,用以说明产能约束下的企业如何将特定产品 — 目的地市场的负面税收冲击,转化为对其他产品和目的地市场的销售额扩张。借助准自然实验性质的出口关税调整场景,并运用高度细化的企业——产品层面贸易数据,我们为中国出口企业存在双重维度的市场联动效应提供了稳健的经验证据。具体而言,结果显示:当企业受影响产品的出口关税上升时,其未受影响产品的出口销售额以及国内总销售额均出现显著增长。进一步分析表明,政策实施后受影响企业的生产边际成本有所下降,这证实产能约束是本文所识别的市场联动效应的核心机制。
