The latter two shopping centres were abandoned. Skudai plaza was abandoned due to bankruptcy attributing to poor business while Kemayan City was abandoned during the period of economic downturn. In fact, Kemayan City was planned to be Johor Baru's single biggest integrated shopping and commercial development project with its 64,800 sq m of retail space.  Kemayan City will be refurbished and redeveloped into a contemporary shopping mall known as B8 mall starting mid 2010. It is expected to be completed to the end of 2012.
Malay, Chinese, and Indian food are being served in restaurants and food stalls. A large variety is available throughout the area. Mamak restaurants are mostly available in Taman Universiti.
As is the norm with many parts of southern johor, many people in Skudai are from other states in Malaysia, attracted by better employment opportunities and double the exchange rate in neighbor Singapore. These immigrants would rent houses in Skudai and other parts of johor, with many preferring to settle down here some years down the road. This has created a housing boom in this area as many local young people are also starting families of their own. The higher income that residents can earn from working in Singapore have resulted in higher disposable income too, thus spurring the entertainment and automotive sectors in johor.
