In order to study the relationship between the age structure of the urban workforce and the adoption of new or significantly improved technologies in service sector firms, the article closes a research gap by analyzing the joint impact of the age of the workforce and the enhancement of teamwork on the probability of adopting new technologies. The empirical analyses, that is based on the data collected from the questionnaire survey, reveals three findings:firstly, firms with a higher share of younger employees are more likely to adopt new technologies. Secondly, the distribution of the age of the workforce has no significant impact on the probability of adopting new technologies. And thirdly, firms which enhance their teamwork and have a higher share of younger workers are less likely to adopt new technologies; whereas firms that enhance their teamwork and have a higher share of older employees are more likely to adopt new technologies.
