Small and medium-sized enterprises (SMEs) have long been the backbone and the focus of development in industrial countries. This study adopted the supply chain process perspective to investigate effects of the supply chain process on the supply chain performance of SME. To it, the supply chain mechanism of SMEs (comprising the production, transportation, and warehousing logistics and the service logistics) and three dimensions of the supply chain performance (capability of operations, flexibilities, and services) were modelled, and then an empirical study was executed in Taiwan. 277 samples were collected, and the SEM(Structural Equation Modeling) method was used to analyze the model. The results showed that the firm's production, transportation, and warehousing logistics positively influenced the flexibility of the supply chain, whereas service logistics affected the operations and services of the supply chain. Findings of this study can be applied to the strategic supply chain configuration of SME.
