There is no link between academia and industry, period
Thinking that there should be link between academia (industry) with (commercial) industry is just like thinking that there is should be a link between automotive industry and food industry.
Yes, there is a link between rubber industry with automotive industry, one as supplier and one as buyer. The relationship is clear. One can make connection from automotive industry with sport industry as sponsor, but naturally there is no connection, it just a cooperation.
When people saying that there should be a link, it is saying that we need to diversify the business
PS: There is sciencedirect paper in the link, very good.
