Hi-tech industries are light industries that involve scientific research and development to produce sophisticated products. They are divided into research and development as well as manufacturing. The location of hi-tech industries is influenced by factors such as access to an urban labor force, transportation infrastructure like airports and roads, proximity to universities for research collaboration, and attractive environments in planned science parks. Tsukuba Science City in Japan is an example of a planned science park located near Tokyo that hosts over 50 national research institutions and 150 private firms in attractive landscaped settings to support the high-tech industry.
