Given the recent push for greener industry, many of the heavy industry players like Shell, Exxon mobile have announced plans to move their operations to lower cost countries. With such a shift, Singapore has to identify new industry or expand existing manufacturing base to fill up the gap. One key industry is semiconductor fabrication plants. It's considered relatively light industry given that its able to site near residential areas, the only consideration is the blast radius for it to be away from places where there is high vibration, which our tradition heavy industrial area may not be suitable. As Singapore government continues to set aside land for such needs, we will see the companies expanding to mitigate the impact of any supply chain risk that they could face with a single hub. 

While there are talks whether there would be slow down, I think the long term growth is still intact compared to many other sectors. The key is where these companies will invest or grow their business in the years to come.
