摘要:Contingency theory points out the adaptive management is crucial point to sustainable firm performance. This research aims to determine the relative importance of a set of variables comprising the four entrepreneurial management variables, i.e. strategic orientation, organization culture, organization structure, and reward system, and a set of environmental turbulence variables in predicting firm performance. This research uses firm-level data with observed population of this research is SMEs in Surabaya, Indonesia. Through adopting hierarchical regression approach and partial least square method, this study indicates that moderating effect of environmental turbulence changes the direction of relationship between entrepreneurial management and firm performance. During low environmental turbulence, entrepreneurial management has positive impact on firm performance, but the direction changes. Entrepreneurial management has negative impact on firm performance during high environmental turbulence.
