Using replication research for just‐in‐time purchasing construct development
通过复制研究验证了即时采购构念的六个因子（高层管理承诺、员工关系、培训、供应商质量管理、运输和交付数量），并确认了其内容效度、信度、收敛效度、区分效度等，为后续假设检验和元分析提供了可靠基础。
Abstract Using replication research, the validity of the just‐in‐time purchasing (JITP) construct is established. Although empirical researchers have examined JITP over the last two decades, a consistent set of valid, reliable factors has not been used. The lack of valid construct is a barrier to hypotheses testing and meta‐analyses on JITP. This study confirmed the validity of six JITP factors: top management commitment, employee relations, training, supplier quality management, transportation, and quantities delivered using two different data sets and testing the first‐ and second‐order structure of the JITP construct. Content validity, reliability, unidimensionality, convergent validity, discriminant validity, criterion‐related validity, and an invariant factorial structure of the JITP construct were empirically established.
