Purpose

Despite the increasing interest in the role of supply chain concentration (SCC) in improving performance, its influence on firms' sustainability performance remains unexplored, as do the underlying mechanisms of this relationship. Drawing on resource dependence theory, the authors investigate the relationship between SCC and manufacturing firms' sustainability performance and the moderating roles of operational slack and information transparency.

Design/methodology/approach

The authors use secondary data from 3,581 manufacturing firms listed on the Shanghai and Shenzhen A-share stock markets from 2006 to 2020 to conduct an empirical analysis using panel data regression models.

Findings

Manufacturing firms' SCC is negatively related to sustainability performance until it reaches a certain point, where SCC positively affects sustainability performance, presenting a U-shaped relationship. In addition, operational slack represented by a quick ratio moderates the relationship between SCC and sustainability performance by flattening the curve. Operational slack represented by receivable turnover ratio moderates the relationship between SCC and sustainability performance by steepening the curve and shifting the turning point left. Information transparency strengthens the effect of SCC on the sustainability performance by steepening the curve.

Originality/value

This investigation provides a comprehensive view of the SCC– sustainability performance relationship.

供应链集中度能否提高可持续发展绩效：运营宽松和信息透明度的作用

目的

尽管人们对供应链集中度（SCC）在提高绩效方面的作用越来越感兴趣，但它对企业可持续发展绩效的影响以及这种关系的潜在机制仍未得到探索。作者利用资源依赖理论，研究了 SCC 与制造企业可持续发展绩效之间的关系以及运营松弛和信息透明度的调节作用。

设计/方法论/途径

作者利用2006年至2020年沪深A股市场3581家制造业上市公司的二手数据，利用面板数据回归模型进行了实证分析。

发现

制造企业的SCC与可持续发展绩效呈负相关，直到达到某一点，SCC对可持续发展绩效产生正向影响，呈现U形关系。此外，以速动比率为代表的运营闲置通过拉平曲线来调节 SCC 与可持续发展绩效之间的关系。以应收账款周转率为代表的运营闲置通过使曲线变陡并将转折点左移来缓和SCC与可持续发展绩效之间的关系。信息透明度通过使曲线变陡来增强 SCC 对可持续绩效的影响。

原创性/价值

这项调查提供了 SCC 与可持续发展绩效关系的全面视图。
