It is viewed as a convenient way to improve disaster response and governmental efficiency. With the extensive use of these social collaboration tools, the governmental agencies of emergency management need measurements to determine the performance of these tools, which help them to understand the direction of improvements. Therefore, this paper aims to provide performance measurements of Web 2.0, social media, and mobile Apps for the governmental agencies of emergency management. This paper involved a survey of top 20 cities in U.S. The quantitative analysis of the survey was conducted by descriptive statistics. In this survey, the performance of Web 2.0 in San Diego is the best among these 20 cities. New York is the first place in the performance of social media. As for mobile Apps, New York still has the best performance. Otherwise, in order to understand the improvement of the performance of social collaboration tools through e-governance, the paper tries to investigate the relationships between social collaboration tools and e-governance capability. Under this objective, the stepwise regression was used to identify the relationships between 5 components provided by U.S. Municipalities E-Governance Report and the social collaboration tools. Findings suggest that Web 2.0 is related to “Citizen Participation” component. In addition, social media is related to “Services” and “Citizen Participation” components. As for mobile Apps, it has close connection with “Usability”. The findings of relationships help municipal administration understand how to improve social collaboration performances through e-governance capabilities. | en_US |
