African Journal of Management Research, 32(1), 63-82.https://uilspace.unilorin.edu.ng/handle/123456789/17068Employee performance plays a pivotal role in determining organizational success. However, due to the incessant job turnover in the Nigerian banking industry, the influence of critical factors such as knowledge sharing behavior and motivation cannot be underplayed. In view of this, this study investigated the influence of the dimensions of knowledge sharing behavior and motivational factors on employee performance of selected new generation banks, in Lagos, Nigeria. A survey research design was adopted using a structured and validated questionnaire to collect data for the study. A stratified sampling technique was used to select 1,628 employees from Six new-generation banks that are listed on the Nigerian Stock Exchange (NSE). Data was analyzed using descriptive and inferential (multiple regression) statistics. Findings revealed that the dimensions of knowledge sharing behavior and motivational factors influenced employee performance positively in the selected new-generation banks in Lagos, Nigeria. Personal interaction had the most significant influence on employee performance, followed by written contributions and organizational communication; while community of practice had the least considerable influence on employee performance. In terms of motivational factors, intrinsic motivation made the most significant contribution to employee performance compared to extrinsic motivation. This study recommends that the management of new generation banks should sustain and improve the channels of sharing knowledge and equally motivate employees appropriately to enhance their performance.enBanking IndustryEmployee performanceKnowledge sharing behaviourMotivationNew generation banksArticle
