Abstract:
Amid a complex and volatile socioeconomic environment, how national qualification certification can guide the effective allocation of resources and enhance supply chain security has become an important issue of shared concern among academics and practitioners. Using data from Shanghai and Shenzhen A-share listed companies, this study finds that accreditation as a National Enterprise Technology Center effectively promotes the diversification of firms' supply chain configurations. This finding remains robust after applying the instrumental variable approach, propensity score matching, and placebo tests. The underlying mechanisms operate through four channels: (1) a signaling effect, whereby accreditation enhances corporate reputation and increases market attention, attracting more upstream and downstream partners to seek cooperation; (2) a capital effect, whereby accredited firms leverage commercial credit to provide informal financing support to supply chain partners, strengthening their willingness to cooperate; (3) an innovation effect, whereby accreditation fosters inter-firm R & D collaboration, helping firms simultaneously expand product variety, output, and competitive advantage, thereby driving greater raw material procurement and downstream market expansion; and (4) a talent effect, whereby systematic talent recruitment and cultivation mechanisms help firms attract highly skilled personnel and promote R & D innovation. Further analysis shows that the positive impact of accreditation on supply chain configuration is more pronounced for upstream segments, highly competitive industries, and state-owned enterprises. In addition, accreditation can reduce operational risk and improve firm performance through supply chain diversification. This study offers implications for fully leveraging national qualification accreditation and further improving innovation support policies.
