It is found that when executives' external compensation is higher than the industry average, executives' external compensation gap has a significant promotion on the preference to carry out R&D internationalization in technologically developed countries; executives' overseas experience and government subsidy excluding the irrelevant part of technological innovation have a positive moderating effect on the relationship above.
