Insignificent variables

[Nitzan04]

Hello,
I am performing linear regression analysis in Eviews and half of my variables are unfortunately with p.value larger than 0.05 , even though i dropped out one variable after detecting a multicollinearity it still doesnt change the p.value of the other variables.
My research dealing with the effect of explanatory variables such as : R&D Expenses, Company Size, repeated/new partner in alliances ,Total alliances and some more, on the number of patents per year in the pharma industry.My question is what is the implication in that kind of case? what can i do?
Thank you in advance
Nitzan.
