E-government advancements have not fully resolved the challenge of providing citizens with a single entry point for services that involve different government entities. The Smart Cities and Service Integration project (hereafter, SmartCities) aims to establish a framework for smart city service integration that would assist in the management of large scale projects related to the integration of services across governments. By using comparative case studies of six cities (New York City, Seattle, Quebec City, Mexico City, Macao, and Shanghai), the project aims to develop a theoretical framework to guide smart cities service integration. The project will highlight integration of public services and cross-boundary information sharing by focusing on specific policy domains. An additional goal of this project is to develop research capabilities of graduate students who participate in the research. The research project is funded by the Social Sciences and Humanities Research Council of Canada.
