What is a good database to search for companies and countries competitive edge?
Regarding finding the competitive edge of companies, one way to find this is to analyse a SWOT analysis, particularly using the Strengths and Opportunities. If you haven't found this yet, you can find it in many of our Company specific databases found on our International Business Guide
The first one the list, MarketLine Advantage, can be searched using your company's name. For most companies, particularly public companies, they'll have extended company reports including a SWOT analysis. This database will also have a competitive analysis on most industries if you search for your particular company's industry.
Other databases on the list will be similarly useful.
In the middle box [Country Reports], the last link "Global Competitiveness Report 2014-2015" should have some of the latest information regarding the competitive edge of each company. If you would like to go beyond this report, have a look at the other databases on this list and their descriptions as many of them cover similar information.
