What are the characteristics of long-lived companies? Do common management practices exist that enhance the probability of a firm's long-term survival? This study attempts a statistical verification of the impact that management practice characteristics possessed by firms at a specific point in time had on their subsequent survival, based on the characteristics of long-lived companies identified in prior research. To this end, a total of 308 companies listed on the Korean Securities Exchange at the end of 1978 were examined, and the effects of firm characteristic factors and management practice characteristics as of 1978 on firm survival over the subsequent 34 years were investigated using the Cox proportional hazards model. The analysis results confirmed that firm characteristic factors such as firm age and size, as well as management practice characteristic factors such as emphasis on human resource investment and technology investment, were factors that enhanced the probability of long-term firm survival even after controlling for firm performance levels. These results suggest the possible existence of common longevity routines that contribute to enhancing firms' long-term survival rates, providing important implications for future research on corporate longevity. Furthermore, this study holds significant value as a large-scale data-driven empirical study on the causes of long-term firm survival, an area where research remains relatively scarce.
