In this paper, fuzzy theory, Markov chain and RFM model are integrated to evaluate customer lifetime values. This approach calculates the profit contribution of customers in every purchasing situation. Firstly, customer purchasing state is updated contiguously by fuzzy theory and RFM model with transition matrix which represents the probabilities among purchasing states. Then the profit contribution of each period is computed by using revenue and cost data. Finally, the profit contribution of each customer is accumulated through some discounting consideration. This will construct the final customer lifetime values.

The proportion of rents that firms get depends on their network capability. This reveals the essential relationships between network resource, network rents and network capability: First of all, network rents come from the network resources. Furthermore, network rent is the representative of the competitive advantage and the value of the network resource. Second, network resource is the foundation of the network capability, the function of network capability is activated in the process of using network resource by firm. It enables the network resource to be a potential value resource of the competitive advantage. At last, network capability activates the network rents in the network resource, and make sure that the firm get the additional benefit;(4) the network capability can be classified as: network visioning capability, network constructing capability, network operating capability and network constructing capability. Some factors, such as maturity of IT, openness of culture, management system involved, experience of participation in network, have a positive effect on the network capability of the firm;(5) the impact of network capability on innovation performance is realized through knowledge transfer between network partners, namely, knowledge transfer is the mediator; and (6) the type of innovation network, exporation network or exploitation network, has moderator effect on the relationship of network capability and knowledge transfer, and network capability and innovation performance as well. In the exploration network, network constructing capability has more effect on the performance of the knowledge transfer and innovation. In the exploitation network, network operating capability has more effect on the performance of the knowledge transfer and innovation.
