The caliber of export products is a microcosmic reffection of economic development quality. This study seeks to elucidate the inffuence of environmental regulation on product quality, integrating the role of the skill premium as shaped by environmental regulation within a Dixit-Stiglitz CES production function model. Additionally, we empirically scrutinize the interplay between environmental regulation, skill premium, and product quality, utilizing Chinese customs export data in conjunction with data from listed companies spanning 2003-2015. The conclusions drawn from our theoretical analysis and empirical veriffcation reveal an inverted U-shaped relationship between environmental regulation and product quality, which is tempered by the skill premium. Moreover, a signiffcant positive correlation exists between environmental regulation and the skill premium. Similarly, the relationship between the skill premium and product quality manifests an inverted U-shape. Notably, an elevated skill premium markedly bolsters the enhancement of product quality through green innovation. These insights underscore the need for balanced environmental regulations and strategic investment in skilled labor to augment product quality. This serves as a valuable compass for policymakers and businesses endeavoring for green innovation and high-quality, sustainable economic growth.
