Diffusion of Next-Generation Vehicles through the Smart City Policy in Saitama

Abstract

This study aimed to elucidate the diffusion factors of next-generation vehicles in Saitama city. The city is one of the most advanced in terms of smart-city policy development, using next-generation vehicles as a technological innovation. The author focused on diverse actors, such as government, private companies, institutions, and residents who used next-generation vehicles. The ways in which those vehicles are used and actors’ interactions were examined from the viewpoint of practical users. Finally, the author collected data from 23 sample actors, comprising one local government body, 11 private companies or institutions, and 11 individuals. All these actors used next-generation vehicles in their own ways in 2015.

Only a few actors had previously used next-generation vehicles as a part of their business. However, after the Saitama city project was adopted, more actors switched to using next-generation vehicles. The reasons why they chose the vehicles were not limited to economic efficiency, but also included the preference for eco-friendly technology, better quality of life, etc. The recognition of those advantages was often due to influence from “first-runner” users of next-generation vehicles. In addition, it was natural that most actors were only adopters of next-generation vehicles in the initial stage, although some gradually became promoters as well.

Consequently, actors’ interactions became more frequent. Next-generation vehicles have gradually become widely accepted. Using next-generation vehicles in Saitama city has become more popular with the increase in actors who use them in various ways and for various reasons.
