Purpose – The purpose of this paper is to examine the effect of work characteristics on members' self-efficacy and collective efficacy, and the subsequent effect on police officers' performance. Design/methodology/approach – A multilevel model is adopted to analyze quantitative data obtained by using 812 police officers and 54 chiefs of police stations in Taiwan as the research objects. Findings – The authors found that work characteristics affected members' self-efficacy and collective efficacy, which further affected the individual- and group-level performance and the contextual effect of social work characteristics (SWCs) and collective efficacy on self-efficacy and individual performance. The authors also confirmed the cross-level moderation of social characteristics on the relationship between motivational work characteristics (MWCs) and self-efficacy, and between self-efficacy and individual performance. Research limitations/implications – A limitation was the characteristics of the sample, which consisted of mostly first-line uniformed police officers in Taiwan. From the perspective of managerial implications, it is felt that police organizations should beef up the training on police officers' collective efficacy, such as building group spirit, improving members' sense of responsibility, and building up trust with the organization. Originality/value – The findings prove that the study of work design is particularly important for enhancing the management effectiveness of police organization, because it explains the causes of a number of organizational behaviors as well as a number of important results that influence the police organization (e.g. efficacy and performance).

The shaping of employees' innovativeness is an important way of building a sustainable organization. Therefore, in order to have a sustainable police organization, the innovativeness of the police must be established in order to achieve the objective of maintaining law and order. In this study, Taiwan's first-line border police officers served as the research subject, and the cross-level model perspective was adopted to investigate their innovativeness from task-oriented and socially oriented viewpoints. At the same time, investigations were made into the cross-level direct and indirect effects of social work characteristics and collective efficacy toward police officers' self-efficacy and innovativeness. A multilevel model was adopted to analyze the quantitative data obtained with 249 border police officers in Taiwan as the research objects. The results showed that social work characteristics have a positive influence on collective efficacy, and motivational work characteristics have a positive influence on employees' self-efficacy and innovativeness. Their self-efficacy showed a positive influence on innovativeness, and a mediating effect on the relationship between motivational work characteristics and innovativeness. Moreover, social work characteristics and collective efficacy have a cross-level contextual effect on self-efficacy and innovativeness, while social work characteristics and self-efficacy have a cross-level interaction on police officers' innovativeness. In general, this study confirmed the importance of employees' innovativeness for the establishment of a sustainable police organization. The characteristics of social and motivational work, self-efficacy, and collective effectiveness are important variables for establishing employees' innovativeness. [ABSTRACT FROM AUTHOR]
