Now many businesses pay more attentions on upgrading their decision-makings and adjusting their organizational structures by making full use of big data and developing information strategy for business decision supports. For group enterprises, however, multi-layered organizational structures, diversified busi-nesses, multi-regional locations along with the complexity and dynamics of strategic governance have shoul-dered the complexity in group information strategic planning and hence the difficulty in its implementations. In order to fetch a reasonable information strategy to enhance the business’s ability in obtaining and integrat-ing information and reducing risks and improve the success rate of the information strategy to achieve the ul-timate goal of integrating the business information strategy with their development strategy, it is important that we approach the study from multiple aspects, multiple angles, and multiple levels to determine the infor-mation demands of the business and the strategic implementation strategy. In the first part, the paper present-ed an analysis of the situations within current information strategy in the context of the so-called “Internet +” environment as adopted by resource enterprises. Then using the tool of big data, the researchers formulated the big data based information strategy (BDBIS) aimed at improving work efficiency and group governance. An empirical study of the DY Coal Group was then conducted and an implementation framework and proce-dure for the information strategy were suggested. The research findings of the empirical study have signifi-cant implications for resource enterprises in formulating their business information strategy and implementing the information strategy.
