Abstract: New enterprises of small and micro-size always lack of resources, and have to obtain resources from their business network, therefore, network capability has become an important factor affecting the entrepreneurial performance, but the influence mechanism of network capability on entrepreneurial performance need to be revealed. This paper puts forward the theoretical model of “network capability, absorptive capacity and growth performance”, and takes 141 small and micro businesses as a sample to empirical analysis. The results showed that, the capacity of network construction, embedding and relationship management all have significant effect on absorptive capacity. Also, the capacities of network construction and embedding have significant influence on growth performance, but relationship management capacity doesn’t have significant effects on growth performance. Entrepreneur’s absorptive capacity has significant effect on growth performance, and it plays some intermediary role between the network embeddedness capability and growth performance, while it plays full intermediary role between the relationship management capability and growth performance.
