To help improve Henan Netcom Company's ability of competition, we also make the environmental analysis, the strategy analysis and the competitive analysis; distinct it's external internal strength as well as weakness opportunity, threat. We assure that the core competition abilities include advanced telecommunication network, large numbers of subscribers and various services. Then this text analysis the competitors, the potential competitors, substitutions, equipment providers and customers by using Porter theory, compare each competitor's ability and the field that they compete drastically. Through conforming the costumer's utilitarian and personal services requirement, it discover that the key factor of development is holding the group subscribers. By Boston Matrix we find out key services, staring services, problem services, then study which service is the most important for us and which one should be throw off. Base on analysis above, this article concludes the general strategy and the service strategy of Henan Netcom: enforce the stable development strategy for certain period, and perform expansion strategy when time is fit.
