Abstract: Based on the comparative analysis of biological characteristics of "Belt and Road" (B&R) oriented enterprise technology standard alliances (ETSA), this paper collects and pre-processes research materials and data via text mining, and then utilizes the coding methods and procedures of proceduralised grounded theory to analyze the ecosystem of ETSA. The paper finds that B&R-oriented ETSA participants mainly include technology standard providers, standard product suppliers, standard product consumers and technology application promoters. There are three forms of interaction mechanism among the participants, namely, standard output and application, standard collaborative construction and standard fusion and symbiosis. On these bases, this paper constructs a model of interaction mechanisms among them and probes into their interactive relationship and the role of each participant plays under different interaction mechanism.

Key words: enterprise technical standards alliance, interaction mechanisms, ecosystems, proceduralised grounded theory
