1. Relations of Public Service Motivation and Job Performance evidence from Vietnam. Polish Journal of Management Studies. 2021, Vol. 23 Issue 1, p385-402. 18p. The factors affecting public service motivation (PSM) on civil servants' job performance in Vietnamese State-owned Enterprises (SOEs) in the telecommunications industry. SOEs have not paid much attention to intensive investment in technology and equipment innovation, production techniques to improve the labor productivity of the staff. The results also attain validity and reliability of variable scales, including PSM, passion and performance. Therefore, SOE's leaders must consider intrinsic and extrinsic PSM to enhance performance. The proposed solutions could be supported in encouraging and nurturing passion and performance of their SOEs. Research results also suggest implied solutions that will help SOEs leaders realize the nature of PSM relating to positive emotions and performance, contributing to the creativity and innovation of their performances instead of relying only on working conditions.
