The country institutional profile (CIP) construct has become the most widely used conceptualization of institutional environment for entrepreneurship. This construct is frequently employed to study institutional forces influencing entrepreneurial activity at the national level. However, relatively little is known about the cross-national equivalence of the construct. Moreover, the institutional environment for entrepreneurship in emerging economies remains largely under-explored. To address these issues, in the current study, we used the most frequently utilized CIP scale to collect data from 809 young adults in four rapidly emerging countries: Brazil, China, India, and South Korea. We examined the invariance of the CIP construct and unraveled differences in perceived institutional profiles among these rapidly emerging economies. Results support the CIP construct as largely invariant in the four REME countries and revealed important differences in specific aspects of institutional environments in these countries. Implications for future research and practice are discussed.
