Influential factors, behaviors and objective performances of smart city construction are exploratively studied by using the grounded theory method based on text sources from the literature at home and abroad. A theoretical model about action mechanism among smart city construction influential factors, behaviors and objective performances is obtained based on the above analyses. Besides, the initial scales of influential factors and objective performances about smart city construction are built. Furthermore, the initial items of questionnaires with a small sample of pretest and reliability tests are modified, and the final items are formed by using exploratory factor analysis. The confirmatory factor analysis of these scales, tests of theoretical model and research assumptions are empirically conducted by questionnaire design and investigation. Finally, the main research conclusions are reached and policy suggestions are proposed.
