Abstract : This paper aims to outline the importance of the cultural dimension in organizational practices of competitive intelligence and environmental scanning by analyzing the case of Chinese enterprises. The article consists of three main parts. In the first part, the authors define the concept of communicational practices of environmental scanning, then examine the cultural dimension and the cultural foundation of those practices. The second part of the paper investigates environmental scanning practices in the cultural context of Chinese enterprises by using primary and secondary data from the literature and from a field work conducted in China during several months from 2005 to 2007. This contextual analysis aims to define the particularities of the Chinese cultural informational system that constraint the implementation of CI systems. In the last part, the authors examine the Chinese practices of environment scanning in the framework of the « informational culture » provided by Davenport and Prusak (1997) and evaluate the adequacy of Chinese CI systems to those practices.
