Abstract:Scientific and technological innovation is the main driving force of urban and regional development. Based on the evidenced data, it is particularly necessary to make a rapid and accurate quantitative evaluation of scientific and technological innovation for a specific city. Based on the evaluation index system and the visual development tools, this study designs a mobile APP for city scientific and technological innovation evaluation and applies it in the practice. The system realizes the functions of index display, index analysis and evaluation in the mobile terminal according to the index data. Moreover, combined with the geospatial information, this APP can browse and contrast the index information of different cities. This is of great significance for promoting the efficiency and accuracy of urban scientific and technological innovation.
