Abstract: As an open organization that has transaction and innovation attributes and can facilitate multiparty interaction and resource integration, platform has inherent advantages in dealing with sudden changes. However, the existing literature lacks adequate theoretical guidance for a platform to achieve rapid iteration in response to environmental jolts. Based on the perspective of search theory, we select the development process of the emergency materials platform developed by Haier COSMOPlat as the research object to carry out an exploratory case analysis, and discuss the internal mechanism of how the platform realizes rapid iteration through instant search under the environment jolts. Our findings are as follows. Firstly, the environment jolts triggers and activates the instant search process of the platform through the dynamic changes and continuous interaction of mutation speed, mutation direction and mutation amplitude. Secondly, the platform uses three kinds of instant search strategies, namely, responsive, forward-looking and leading, to deal with the dynamic impact of the environment jolts in different development stages, and different search strategies will present different search tracks of “stimulus-connection-discovery”. Thirdly, the platform instant search in the context of environment jolts will promote the rapid iteration of the platform through three dynamic matching modes of resources and requirements: bridging, focusing and verifying. The research conclusions have a good theoretical and practical value in revealing the inherent law of platform evolution and optimizing platform operation in the context of environmental jolts.
