I think you need to narrow down your scope of study and be more specific to your research question. Anyway, you may find the following articles useful for starting your research:
Storeya, D,J and Tetherb, B.S. (1998), New technology-based firms in the European union: an introduction, Research Policy, 26(9), pp.933–946.

I add a short list of papers that may be relevant. The papers can be downloaded from ResearchGate.

It seems you are searching for fresh opportunities for research in the area of entrepreneurship, this particular editorial in the Journal of Business Venturing by Dr Dean Shepherd will be of use.
Titled "Party On! A call for entrepreneurship research that is more interactive, activity based, cognitively hot, compassionate, and prosocial" in the Vol 30 Issue 4 of JBV (2015).
The paper is available for download from our RG Community.
The other source will be the January 2011 Special Issue "The Future of Entrepreneurship Research" in Entrepreneurship Theory & Practice Journal. It opens up a number of areas of interesting research possibilities in Entrepreneurship.
With these two sources, you should be able to have numerous new and emerging themes in Entrepreneurship Research.
Feel free to read my papers on opportunity recognition in Journal of International Marketing, International Marketing Review, and the more recent one in Asia Pacific Journal of Management. All the papers are in my ResearchGate page. Good luck!
