Abstract

The pharmaceutical sector serves as a cornerstone for safeguarding public welfare and national security. Driven by intensifying market and customer network volatility, mitigating financing constraints and recalibrating strategic deployments to bolster financial performance have become top priorities for pharmaceutical firms. Utilizing panel data from Chinese A-share listed pharmaceutical enterprises spanning 2016 to 2023, this study scrutinizes the nexus between customer concentration and corporate financial performance, with particular emphasis on the mediating role of financing constraints. The empirical evidence reveals a pronounced, negative impact of customer concentration on financial performance. Specifically, customer concentration acts as a structural impediment that stifles firm performance by compounding existing financing constraints, thereby confirming a distinct mediating channel. These findings suggest that pharmaceutical firms should diversify customer portfolios and alleviate financing constraints to achieve sustainable performance growth.
