PROBLEM STATEMENT SMES make a significant contribution to economic development via the creation of employment, technological advancement, reduction of poverty, innovation, and wealth distribution (Agyel, 2018; Ye & Kulathunga, 2019).Existing findings on these factors have generally been inconclusive (Essel, s, & Amankwah, 2019; Isaga, 2018) Thus, this gicular study investigated the effect of significant SMEs' performance, including operation efficiency, Avallabillty of business information, access to infrastructure, and Business environment on SMEs' performance to address the gap found in the entrepreneurial literature and practice of Saudi SMES.It was noted that most Saudi SMEs randomly prepare economic feasibility studies to obtain loans and financial support, which is another major issue that contributed to the fallure of mkof nandal resources, sfficlency that influences for SMES, a lack of managerial compet projects (Tripathil, 2019).Particularly the role of operation efficiency, Avallability of business information, access to infrastructure, and Business environment in predicting SMES formance is deficient in prior studies (Karadag, 2017; Ying et al., 2019).
