摘要

Enhancing the regional power supply through cross-regional energy infrastructure is crucial for alleviating the firms’ export volatility. This study utilizes data from the Chinese Customs Database and the Chinese Industrial Enterprises Database, spanning the period from 2002 to 2013. It employs ultra-high voltage (UHV) transmission projects as a quasi-natural experiment, applying the PSM-DID method to explore the impact of energy infrastructure on firms’ export volatility and its mechanisms. Firstly, the results show that UHV projects reduce firms’ export volatility by about 2.25%, with the effect remaining robust after multiple checks. Secondly, the mechanism analysis suggests that they reduce firms’ export volatility by alleviating power constraints and reducing inventory costs. Thirdly, the heterogeneity analysis reveals that UHV projects on firms’ export volatility are more pronounced in receiving power regions and multi-product exporting firms. Finally, further analysis shows that the stable energy supply helps prolong firms’ export duration and facilitates their upgrading in global value chains. This study extends the focus on infrastructure and trade to energy infrastructure, providing empirical evidence that it helps stabilize firms’ export performance.
