Native language as compared to? You might like this special issue in the Journal of International Business Studies: https://link.springer.com/journal/41267/45/5/page/1 It's mostly about language in multinational / multilingual settings but it might speak to your question?

Language is the key element of culture and to be a successful entrepreneur one should be aware of the native cultural elements which can help in the localization of the products.

Looking at your question as formulated, I doubt if native language alone will impact entrepreneurship and entrepreneurship performance.

I would think culture may have an influence. But in the conduct of international business, native language may well have an influence, but I suspect that is possibly because native language may well be intertwined in cultural antecedents, by which I mean the ways of thinking and social behaviour perhaps, and may have some influence. Consider China... that country has produced an enormous number of entrepreneurs who are very successful, possibly because China constitutes a huge market of more than 1.3B people and if only 1% of that population or even a fraction of 1% should buy a product, success is very likely. In India too, there are numerous examples of successful entrepreneurship.

I think it is the thinking, the attitude and behaviour that has an influence on entrepreneurship not language. If culture, and particularly one often related to religion suggests that something is pre-ordained, it might act as a brake on some people ignoring initial failure and trying anew,

This is an utterly interesting question! As a start, I would recommend the work of M. Keith Chen (a Chinese American behavioral economist) and more specifically The Effect of Language on Economic Behavior: Evidence from Savings Rates, Health Behaviors, and Retirement Assets, American Economic Review, 2013. This may not yet be a full answer to your question but definitely a worthwhile perspective on the impact of native language(s) on economic decision making and behaviour that may be a great inspiration to your research design or approach. I would be very interested in your results.

Thank you Andrea Cnyrim, Phil Barbonis, Richard Haans and Suhail Mohammad Ghouse. I am still finding a way out and definitely i will share my findings.

Appreciated :-)

yes language plays a very important role, a recent study though yet to be published found that local language proficiency is instrumental to the ability of immigrant entrepreneurs to cope with their business.

i hope this helps.
